Data reception pulse, 0.5uS or greater pulse width required. Usual state is HIGH, and reads data after going to LOW state.

The DATA0 through DATA7 signals represent data bits 0 to7, respectively. Each signal is at high level when data is logical 1 and low level when data is logical 0. These signals are used to transfer the 1284 extensibility request values to the printer.

When LOW the printer has finished preparing to receive signals and can accept data. Pulse width is about 1uS or 3uS Printer clock signal.

HIGH means the printer cannot receive data. This occurs when the printer is receiving data or when the printer is in an error state.

HIGH means no paper is loaded. (LOW means an error.) Always HIGH. Pulled up to +5V via 1.0Kohm Not used

Pulse width of 50uS or more means LOW pulse, and the falling edge of LOW signal causes the printer to initialize.

Note 1: *1 The return side means the twisted pair return and is connected to the signal ground

level. Furthermore, when interfacing, a twisted pair cable should definitely be used for each signal and the return side should definitely connected. Also, use of a shielded cable and connection to the chassis ground of the center machine and the printer, respectively are effective countermeasures against noise.

Note 2:All the interface conditions are TTL level standard conditions. The rise and fall time of each

signal is 0.2 _s or less.

Note 3:There must not be any data transfer with disregard of the /ACKNLG or BUSY signals. (Data

transfer to this printer must be performed after the ACKNLG level is confirmed or when BUSY is in the “LOW” state.)

Note 4: A horizontal line above the signal name sows a LOW active signal.

1.2.1.1 Receiving Buffer Full Operation

When receiving data via the parallel interface or the optional Type B interface while in a state where no error has occurred (including the Pause state), if the available capacity of the buffer drops to 4 KB or less, the printer receives at 1 byte/sec. and prevents the host from issuing a time out.

At the point when the available capacity of the buffer becomes 8 KB or higher, 1 byte/sec. reception is canceled and reception stops when the available capacity is 32 bytes or less. At the point when the available capacity recovers to 1K-byte or higher, reception at 1 byte/sec. is resumed.

Product Description SPECIFICATIONS 22

EPSON Stylus Pro 9500 Revision A

1.2.1.2 Interface Selection

It is possible to switch between the manual fixed selection function or auto selection function to select one of the interfaces which the printer is equipped with (parallel, serial or optional interface).

o Manual Fixed Selection:

One of the interfaces which the printer is equipped with, can be selected and fixed as the default setting.

o Auto Selection Function:

After the power is turned on, the interface from which data are first received is selected. After that, if a predetermined period of time (fixed at 10 seconds) passes during which the reception of data is stopped, the printer enters the idle state (a state where no interface is selected), then selects the interface from which it first receives data next.

o Concerning interface selection and interface state:

n When an interface other than the parallel interface is selected, the

parallel interface is set in the BUSY state. At this time, the LH signal goes “L.” The meaning of LH = L is that the power is cut off. That is, it shows that the 1284 interface cannot respond. Therefore, a host computer requesting reverse transmission must first check LH. When the serial interface is not selected, DTR switches to the MARK (High) state.

n When the optional interface is not selected, the OFF-LINE bit is set in

the Main Status Register (MNSTS).

n After the printer has been initialized, or when it is in the idle state (with

no interface selected), the status of each interface is a shown below.

• Parallel Interface : READY State

• Serial Interface : DTR = SPACE (Low) State

1.2.2 Initializat io n

This section describes the initialization procedures for the EPSON Stylus Pro

9500. There are three ways to initialize the EPSON Stylus Pro 9500:

o Hardware initialization:

When the power is turned on or a cold-reset command is sent to the printer (remote RS command), the printer does the following:

n Initializes the printer mechanism n Clears the input data buffer n Clears the print buffer n Restores the default values

o Software initialization:

When the printer receives an ESC@ command, it does the following:

n Clears the print buffer n Restores the default values

o Control panel (operator) initialization:

When the Reset button is pressed or the printer receives an -INIT signal (negative pulse) from the parallel inter face, the pr int er :

n Paper Eject (In the case of roll paper, the printed part is skipped and

when “Auto; Cut” is set in the paper select settings of the panel settings, the paper is cut, and when “Cutter Off” is set, the paper is not cut.)

n Caps the printheads n Clears the input data buffer n Clears the print buffer n Resets the default values

• Optional Interface : OFF-LINE bit of the Main Status Register (MNSTS) is reset.

n An interrupt signal, like the -INIT signal of the parallel interface, is

disregarded while that interface is not selected and while in the Nibble mode or ECP m ode.

Notes:

1) The setting values in the above table with underlines are default setting values.

2) In the “Roll Paper Margins” setting, if “Vertical 15 mm” (15 mm is set at the top and bottom, and 3 mm is set at the left and right), or “15 mm” (15 mm is set at the top, bottom, left and right), the printing position of vertical lines and horizontal lines in the portion where 15 mm is set at a position 12 mm wider than the logical paper (the minimum margin is an area of 3 mm from the paper edge). (Therefore, the margin becomes 3 mm + 12 mm = 15 mm.) Also, if the printable area becomes X = 15 mm or greater from the right edge of the paper, that portion is not printed on.

3) If the “Paper Skew Error Sensing” setting is turned OFF, even if the paper is skewed as it is being fed, printing will continue, and even if the printed image spills over the edge of the paper due to skewing, the printer will not give notice of the error, so the user should take full responsibility for the possible consequences of this setting.

4) If the “Paper Width Sensor” setting is turned OFF, even if the paper is sensed to be in an abnormal state, printing can be continued, but in that case, the paper width is decided and printing continued based on the following standards.

• The paper’s left edge position is made the guide mark position on the paper guide.

• The printable area is the printable area specified in the command. If the “Paper Width Sensor” setting is turned OFF, if printing is being done on a paper which has

a particularly low reflection rate and cannot be detected by the photosensor, this setting is used. Through the “Paper Width Sensor” OFF setting, if an image which is larger than the set paper is printed, printing may be done on the platen, so the user must take the responsibility for the possible consequences. However, if detection of the top edge of the paper fails, it results in an error.

GAP ADJUSTMENT MENU (BI-D ADJUSTMENT MENU)

Table 1-26. Gap Adjustment Menu

The paper thickness setting, Bi-D, gap (adjustment of the Bi-d deviation between the left and right heads), and printing of the adjustment pattern as well as adjustment are executed in the gap adjustment menu.

Each setting is made by operating the following panel buttons. If you select the Gap Adjustment Menu, you cannot proceed to selection of the other items without performing the “Paper Thickness” setting. After setting the paper thickness (using the Set button), the menu automatically changes to the adjustment mode.

Setting Method

1.3.3 Maintenance Call

1) Set paper.

2) Enter the Gap Adjustment Menu by the panel.

3) If the paper thickness is set on 0.2 mm or 1.2 mm by the panel, it is recognized as being the same as “Standard.” If you are setting other values, input the paper thickness for the paper you are using in 0.1 mm units, in accordance with the paper’s specifications. The purpose for inputting the paper thickness at the first is to enable the printing of a pattern right from the first that is thought to be close to the correction value that is already being maintained by the printer, and thus to reduce the number of times the operation has to be repeated.

4) Select an adjustment pattern to print (either all or individually) and print it. After printing, the adjustment value input menu for that pattern will be displayed in the LCD.

5) Input the pattern No. for the printed pattern that has the smallest deviation in each adjustment item displayed in the LCD.

6) Repeat steps 4) ~ 5) until adjustment of all the items has been completed.

Note 1) If you are carrying out gap adjustment printing, printing paper with the

following lengths is necessary.

n When selecting and printing 1 pattern:Approx. 7 cm. n When selecting and printing all printing patterns (6 patterns): Approx.

40 cm.

Some of the mechanical units used in this printer have counters which count down the remaining service life based on the proper service life for each unit, and when the predetermined value is reached, a “Maintenance Call nnnn” message is displayed. If this message is displayed, it indicates that the end of the service life of the affected unit is nearing, so it is necessary to replace the affected unit as soon as possible.

If this message is displayed, the “Print?” or “Printing” display message is replaced with the “Maintenance Call nnnn” message, and after replacing the affected part, it is not cleared but continues to be displayed until the counter is cleared in “Maintenance Mode 2.”

In the Stylus Pro 9500, when the remaining capacity of the waste ink pad is less than 1% only, the following maintenance call is displayed in the LCD.

Even if the maintenance call is displayed, it is treated as a warning and it is possible to continue printing.

2.1.1.1 Carria ge Mechanism

CR GUIDE RAIL

To print on paper as wide as B0 Wide, the printhead carriage must be more stable and must travel further than the usual carriage. To make the printheads more stable, EPSON added the CR Guide Rail to the SP 9000.

Every EPSON ink jet printer until now has used a carriage guide shaft to stabilize the carriage during printing and horizontal movement. SP 9000 does away with the carriage guide shaft and relies on the printer frame for its stability.

The CR motor uses a DC motor to move the carriage, and the Linear Encoder determines the lateral position of the carriage by counting the shaded areas of the plastic Step Ruler (timing fence). See Figure 2-5 below. The Linear Encoder reads the shaded stripes to determine the position of the carriage as well as the carriage speed, and this data is sent to the software servo. To allow for the extra distance the carriage must travel during printing, the rubber timing belt has been changed to a belt made from steel.

The following sensors are used in combination with the CR Guide Rail components:

o HP Sensor

This optical sensor activates when the CR Guide Rail flag (flag) enters the space between the light emitter and the light receiver. The flag is located just above the home position, and the HP sensor sends an “On” signal when the carriage is in the home position.

o Linear Encoder

This encoder is mounted on the back of the carriage and outputs pulses corresponding to the position of the slits in the timing fence that is incorporated into the CR guide rail which are used for CR motor software servo control and PTS (Print Timing Signal) generation. This linear encoder has a 2-channel digital output format, with phase A and phase B, and the resolution of each phase is 1/180 inch. Each phase is output so that it deviates 1/720 inch from the other phase and if full edge output of both phases is used, the minimum resolution is 1/720 inch. The CR moving direction is monitored by the CPU through the combination of the phase A and phase B output waveforms.

CARRIAGE UNIT CONFIGURATION

In this printer, a carriage holding and drive mechanism construction which differs from previous models is used. The carriage configuration consists of the following major part s.

o Base Carriage :1unit o Sub-carriage :1unit o Print Heads :2 units (Dark system, Light system heads) o Slide Eccentric Cam, Slide Gear

The mounting position of the base carriage is maintained at a constant distance with respect to the paper surface at all times. Consequently, in order to enable changes in the gap between the paper print ing surfac e (platen surface) and the head nozzle surface, a sub-carriage is mounted on the base carriage to which the print heads are fastened.

The sub-carriage is mounted on the base carriage in a state where is can move in the vertical direction with respect to the paper surface by means of the SLID eccentric cam, which is driven via the SLID gear. Through this mechanism, the construction is such that the print heads can move to the set gap position.

Vertical movement of the sub-carriage with respect to the paper surface is possible only in the case that the carriage is in the home position (HP). At that time, the SLID motor pinion gear (PG moving motor) and the SLID gear mounted on the SLID eccentric cam shaft engage, and the SLID cam is driven by the SLID motor’s rotation, causing the sub-carriage (including the print heads) to be raised or lowered to the proper gap position.

The print heads used in this printer are the same as those used in the Stylus Pro 5500 and Stylus Pro 9000, and the head mounting method on the subcarriage also has the same construction. Therefore, if the print heads are removed or installed, or replaced, it is necessary that the respective inclinations and of the dark system head/light system head in the horizontal direction (carriage scanning direction) and the light system head nozzle height with the dark system head nozzle position as the reference in the vertical direction (paper transport direction) be set with the adjustment lever. For details, see Chapter 5, “Adjustments.”

EPSON Stylus Pro 9500 Revision A

CARRIAGE DRIVE MECHANISM

Driving of the carriage is accomplished using a DC motor which is controlled a software servo through the means of a linear encoder. Basically, in the control circuit, the torque calculation processing necessary for motor drive based on carriage drive commands (position commands) is carried out and the motor is excited and driven by the PWM output. Then the carriage position movements executed by motor drive are fed back by signals generated by the linear encoder as carriage position information and moving speed information for the position commands and the carriage is controlled so that it moves at a constant velocity.

o Print Control

Carriage drive speeds i print operations are as shown below.

Table 2-2. Carriage Speed

Print Mode Carriage Speed Head Drive Frequency

33.3 IPS 12 KHZ

o Stop Control

Carriage stop control is executed at the point when acceleration - constant velocity - deceleration control processing is completed and is controlled by position control through the software servo and a stabilization time (in position time) at the stop position.

o CR Motor Trouble Detection

If the difference between the specified position given to software servo control and the current carriage position read by the linear encoder exceeds the specified number of pulses generated, a fatal error (CR Motor out of Synch: Service Call 00010005) occurs.

PAPER WIDTH DETECTION SENSOR

This sensor is mounted on the sub-carriage and detects the paper’s left and right edge positions, identifying the paper width and judging if the paper is skewed. If it recognizes that there is paper present, its output voltage is raised and if it recognizes that there is no paper present, its output voltage drops.

PG SETTING MECHANISM

In order to maintain the distance between the print head nozzle surface and the paper constant in correspondence with the thickness of the paper used, a mechanism is incorporated into this printer’s carriage which enables the print head position to be set in 3 stages in the height direction as viewed from the paper surface. The PG home position is detected by the LID home position detection sensor mounted on the right frame and the SLID gear.

A reflective type photosensor is used in the SLID home position detection sensor, and this detects the position of the notch in the SLID gear and make that the home position.

The mechanism is configured so that when the sub-carriage is in the lowest position, the sensor’s output is “OFF,” and the point when, during the detection operation, the head drops down from its position after rising up, and the sensor’s output changes from “ON” to “OFF,” is recognized as the mechanical PG home position (PG = small).

Changes in the PG value from the PG home position are implemented by the following operation

o PG home position → SLID motor pinion gear rotates CCW (Note) → SLID

gear

→ SLID gear shaft rotates CCW → SLID eccentric cam rotates CCW

→ Sub-carriage modes up (PG becomes wider).

Note): CCW rotation is the rotational direction shown if you are looking from the printer’s right side.

The SLID eccentric cam is eccentric in 3 stages and the following 3 stages of PG value setting are enabled by the number of SLID motor CCW rotation steps in the above operation.

CR LOCK MECHANISM

This mechanism uses a magnetic solenoid, and when the carriage is in the standby state in the HP position, (CR motor excitation OFF), it locks the carriage’s position. When the carriage is in the locked state, power to the carriage is turned OFF, the actuator rises up and a projection engages with the back surface of the carriage, binding the carriage. When carriage lock is released, power to the carriage is turned ON, the actuator is withdrawn from the carriage and the lock engagement is canceled.

2.1.1.2 Paper Feed Mechanism

PF RAIL UNIT

The paper transport mechanism is made of the same extruded aluminum material as the CR guide rail and consists of a grid roller (PF roller) mounted on the PF rail and the pressurization and follower roller assembly mounted opposite to it on the back of the CR guide rail. The grid roller (PF roller) in the Stylus Pro 9500 differs from the grid roller (PF roller) in the Stylus Pro 9000, in that there is only one. (In the Stylus Pro 9000, there are 3 fixed length rollers lined up across the breadth of the printer, linked together with a coupling construction, and fastened to the PF rail via bearings.)

A CD motor is used for the PF motor and this motor is software servo controlled based on pulses output from an optical rotary encoder. In the Stylus Pro 9000, an encoder sensor and loop scale are built into the PF motor, but in the Stylus Pro 9500, the PF motor and encoder sensor/loop scale are separate units, with the loop scale mounted at the left end of, and concentric with the PF roller and the encoder sensor also assembled separately in the printer’s left edge.

Driving of the PF roller is done by transmission to the PF roller through the following channel.

o PF motor pinion gear _ Timing belt _ Reduction pulley _ Grid roller (PF

roller)

Suction fans are also mounted on the back side of the paper guide L (the space in back of the paper guide L is divided into 3 cavities arranged side by side across the width of the printer with one suction fan mounted in each cavity), and by these fans pulling air from the back side of the paper and out through the printer body, a suction force is applied to the paper guide L’s surface which acts to stabilize paper travel (preventing it from lifting up). Furthermore, the air volume is controlled by firmware (fan rotation duty control) based on the printer’s operating state (when paper is set, during printing, etc.).

SENSORS

The following sensors and mechanisms are mounted in the paper transport path.

o P-FRONT Sensor

A reflective type photosensor is used for this sensor, which is mounted on the back of the paper guide L. This sensor’s detection state is used as the reference point for the paper’s position control in the paper feed direction (top of form during the paper set initialization operation, etc.). When there is paper present, the voltage rises and when there is no paper, the voltage drops.

o P-REAR Sensor

A reflective type photosensor is used for this sensor, which is mounted on the back of the paper guide U. This sensor senses when the printer is out of paper by detecting the rear edge of the sheet and starts the paper setting operation (starting the suction fans, etc.) by detecting the front edge of the paper when the paper is set. Just like the P-FRONT sensor, its voltage rises when paper is present and drops when there is no paper.

o Paper Thickness Detection Sensor

A transmissive photosensor is used for this sensor, which is mounted on the H top guide. A detection lever is mounted on the pressurization and follower roller assembly on the HP side and the detection lever position, which changes according to the thickness of the paper inserted between the grid roller (PF roller) and follower roller is detected by this sensor.

o Paper Set Lever Detection Sensor

A transmissive type photosensor is used for this sensor. It detects the flag position on the rear edge of the paper set lever mounted on the right side frame. When the paper set lever is in the set state (Paper Set position), the sensor’s output is “HIGH.”

PAPER FEED CONTROL

In this printer, only roll paper and cut sheet paper can be used due to its friction feed system. The printer’s status is detected by various sensors mounted along the paper feed path and fed back to paper feed control.

o Paper Suction Fan Control

In order to provide assistance during setting of paper and stabilize paper feeding during print operations, the three paper suction fans mounted behind paper guide L pull o the paper from the back side of the sheet. The fans are run at a constant velocity during printing, but when the paper is set, the following control is carried out to improve setting characteristics. Suction fan air flow control is carried out based on the paper sensing timing of the P-Rear sensor and the P-FRONT sensor. Detailed control methods are as shown below.

2.1.1.3 Cleani ng Mechanism

This printer’s cleaning mechanism has the same mechanical configuration as that in the Stylus Pro 5500 and Stylus Pro 9000. (However, it differs in its component parts. See below for details.) The major component parts are described below.

o Pump Assembly (Cleaner, head installation)

Suction of ink from the head nozzle through the cap is used to accomplish cleaning. Through rotation of the pump wheel, and by pressing the ink tubes connected to the cap, the internal pressure change accompanying the change in the tubes’ internal volume causes the ink to be sucked up.

o Pump Drive Motor (Stepping Motor)

This is an exclusive motor that drives the pump assembly.

o Cap Assembly (Independent type for the dark system head and the light

system head) This protects the print head nozzles when they are not operating and seal

off the head nozzle surfaces during the cleaning operation. The cap assembly in the Stylus Pro 9500 uses new tubes to redu ce evapo ratio n o f the moisture in the ink.

o F Box R

This is a receptacle for the ink that is discharged during flushing, with the ink being discharged to the waste ink tank. In order to carry out flushing on the side opposite the HP side, the F box L and waste ink tank (L) are also provided separately. As for flushing in the Stylus Pro 9500, in order to prevent mist from forming on the head nozzle surface during flushing and in order to prevent the mist from condensing on the flushing box discharge outlet, a construction with a new part (bell eater) added has been adopted.

Each of the above units is mounted on the sub-frame and fastened to the main frame. (However, the F box L is a separate unit.) The CR lock mechanism is also mounted on this sub-frame.

EPSON Stylus Pro 9500 Revision A

2.1.1.4 Ink Supply Mechanism

The two ink cartridge holders each hold three cartridges, K, C, and M on one side and Lc, Lm, and Y on the other side. The design of the holders makes it quite easy to install and replace ink cartridges from the front of the printer. The I/H Lever opens and closes the I/H door, and at the same time it changes the angle of the Ink Cartridge Holder Assembly as shown in Figure 2-16, "Ink Supply Mechanism". To prevent users from accidently installing a color ink cartridge in the wrong slot, the cartridges have slightly different designs. Stylus Pro 9000 dye ink cartridges have the same physical shape, so they can be inserted in each color’s ink cartridge slot, but in order for the ink cartridge’s type to be distinguished by the ink ID sensor, the message “Replace ink cartridge” is displayed in the LCD panel and printing is not possible. See “I/H Assembly Sensors” on page 64 concerning sensor details.

Another important feature of the ink cartridge holders is the ink valve, which is located on the outer sides of the ink cartridge holders and shuts off the flow of ink during printer transportation. The valve close under the following conditions:

n The user turns the valve to the “CLOSE” position to transport the

printer.

n The I/H lever is lifted to the up/cartridge install position.

The ink flows out of the ink cartridges, through stainless steel pipes, through ink tubes, and finally into the printheads.

I/H ASSEMBLY SENSORS

The following sensors are located in the I/H compartment.

o I/H Assembly sensor

This optical sensor detects the whether the door is open and the I/H Assembly is in the install position or the door is closed and the I/H Assembly is in the print position.

When the I/H door is open, the signal = ON When the I/H door is closed, the signal = OFF

o Ink Cartridge sensor

This mechanical sensor (microswitch) is built in all six ink cartridge slots. When the I/C is installed, switch = closed

When the I/C is not installed, switch = open

o Ink Low sensor

This mechanical sensor (microswitch) is at the bottom of all six ink cartridge slots and detects when ink is running out. When the I/C is nearly empty, the switch = open When the I/C is not low (normal), the switch = closed

o Ink ID sensor

This optical sensor is located at the side of all six ink cartridge slots and detects the which market the cartridge is for. Although not implemented currently, the sensor can also detect the type of ink (presently dye only) and the type of special color (if new colors are introduced in the future). The Ink ID sensor looks for the following marks on the ink cartridge.

2.1.1.5 Cover open sensor

To ensure proper paper feeding and to prevent paper jams, the front cover must be closed during printing. There are two cover open sensors, one on each side of the printer, that detect when the cover is open using an interlock switch. When the cover is open, the relay that controls the current to the CR motor and PF motor cuts off the flow of that current. The motors lose their electromagnetized state when the current is cut off.

Figure 2-18. Cover Open Sensor

The sudden loss of current to the motors can cause problems and may even damage the motors or the printhead. To prevent this, a discharge from the capacitor connected to the current circuit is used to slow down the current before it is totally cut off. This process ensures that printing stops when the cover is open without causing any damage to printer parts.

2.1.2.1 Reset Circuit

The Reset-IC (IC7/BH6150F) used in the C277MAIN board has two built-in reset circuits, each of which detects input voltage and power supply voltage respectively as shown in the diagram on the right.

Pin 2 detects the voltage level of the head driver, using the input terminal of the input voltage detection circuit. The voltage level to be detected is preset at

1.25V. When the preset voltage level is detected, the Pin 2 sends a reset signal to reset the mechanism control circuit.

Pin 8 detects the voltage level of the logic power supply, using the input terminal of the power supply voltage detection circuit. The voltage level to be detected is preset at 4.2V. When the preset voltage level is detected, the Pin 8 sends a reset signal to reset the main logic circuits.

2.1.2.2 CR/PF Motor Driver Circuit

The EPSON Stylus Pro 9500 uses the DC servomotor to drive the CR and PF motors. Therefore, the encoder is installed to detect the position, direction, and speed of the carriage, and feedback from the encoder enables the software servo control system to control the CR/PF motors.

The signal received from the Pin 60/61 in the IC32 enables the chopping control system to control the output from the motor drive IC, and the output from the Pin 10 in the motor drive IC (IC35/33) feeds back the output current level to the IC32.

The Electro-magnetic Relay (LA1/LA2) is located on the power supply line for the DC/PF motors, and it cuts off the power supply when the front cover is open.

2.1.2.3 Head SLID Motor Driver Circuit

The Head SLID Motor vertically adjusts the position of the printhead on the carriage according to the thickness of the media in the printer. The motor is driven by the constant current bipolar drive system, and the current supply to the motor is controll ed by the PWM current control system. The 4-phase 48pole PM pulse motor is used for the drive motor, and it is driven by the W1-2 phase excitation.

Based on the preset data received from the IC20, the motor driver IC (IC31) determines the current level to be output to the motor, and the motor is driven by the drive phase switching signal which is input into the Pin 25/18.

2.1.2.4 Pump Motor Driver Circuit

The 4-phase 200-pole HB stepping motor is used to enable the ink system to conduct ink absorption. The basic control method and the circuit configuration are the same as those of the Head SLID Motor Driver Circuit.

EPSON Stylus Pro 9500 Revision A

2.1.2.5 Printhead Driver Circuit

The EPSON Stylus Pro 9500 uses the same printhead as that of the EPSON Stylus Pro 5000 (both dark-color head and light-color head), and the basic configuration of the driver control circuit is also the same.

Print data is rasterized on the memory (DRAM). Triggered by the LAT signal (BHLAT, CHLAT), the IC13 reads the print data in the format and the order according to the print mode, and transfers the data to the printhead (driver circuit on the printhead) synchronizing with the clock signal (BHCLK, CHCLK). The IC13 is equipped with the counter function, which keeps count of each color’s data "1" being transferred to the printhead, and the accumulated count is used to calculate the ink consumption.

The waveform signal is processed at the IC13. Triggered by the input of the PTS signal from the CPU (IC8), the waveform signal is input into the DAC in the IC37 as 10-bit data, synchronizing with the clock signal (20mHz). The DAC then converts the head driver voltage waveform data to analog data, and outputs it to the trapezoid waveform generation circuit (common driver).

The driver circuit on the printhead (nozzle selector) receives the serial data on nozzle selection ("H" level = printing nozzle / "L" level = non-printing nozzle) from the IC13. The circuit then latches the data to the data latch using the LAT signal, and selects the printing nozzles and non-printing nozzles. Once the nozzles are selected, the trapezoid waveform generation circuit (common driver) generates the trapezoid waveform to fire ink. The NCHG signal (BHNCHG, CHNCHG), which is input into the printhead from the IC13, prepares all the nozzles for the next firing by applying slight vibrations during the non-printing phase.

2.1.2.6 Sensors

The output signal sent from each sensor of the EPSON Stylus Pro 9500 is connected to each IC on the control circuit as shown in the diagram on the right.

In order to process the detected results as analog signal, the following sensors input the results into the analog port in the CPU (IC8) via comparator. The analog signal is then converted to the digital signal by the CPU built-in ADC (10-bit) and is compared with the standard value for state analysis.

o P_REAR Sensor o P_FRONT Se nsor o P_EDGE Sensor

Concerning these sensors, since it is necessary that the reference voltage (threshold) be set at the proper level during AD conversion to match each sensor’s characteristics, if the main board is replaced, or if the sensor boy is replaced, it is necessary to adjust the level using the volume (variable resistor) on the circuit board.

Also, the Thermistor inside the print heads detects the head internal temperature, feeds it back to the CPU and carries out drive voltage correction control to match changes in temperature.

3.1.2.1 Errors that require a service technician

Here, the contents and treatment methods for each error that requires a service man mentioned on the previous page are explained.

MAINTENANCE REQ. 0100

o Problem

The waste ink pads have absorbed 99% of their potential. The printer can continue printing, but the “Maintenance Req. 0100” message appears instead of the “Ready” or “Printing” messages.

o Solution

Replace the following parts and reset the ink counter

n Waste Ink Pads (right, left) n F Box (right, left) n Pump Assembly n Cap Assembly n Cleaner, Head

SERVICE REQ. 00000100

o Problem

The waste ink pads are completely full, causing a fatal error. The printer stops printing.

o Solution

See the solution for Maintenance Req. 0100.

SERVICE REQ. 00000101

o Problem

A printer part has exceeded its useful life, and to prevent damage to other parts as well as abnormal operations/printouts, an error occurs. This error occurs when the CR Motor has reached 2.5 million passes, and this indicates the Ink Tubes should be replaced due to excessive wear and tear.

o Solution

To make sure the Ink Tube is not worn out, verify no part of the tube shows wear, is loose, or leaks ink anywhere, especially the tube area between the printheads and the ink pipes.

SERVICE REQ. 00010000

o Problem

PF motor encoder check error The PF motor makes small revolutions clockwise and counter-clockwise. When it turns, the printer checks the rotary encoder output signals to make sure the motor is turning at the correct speed/distance. If there the encoder doesn’t send the correct signal or output data, an error occurs.

o Solution

Make sure there is nothing blocking the grid rollers. If that does not solve the problem, check the PF motor encoder connection. If there still is a problem, try the following.

n Check and adjust the PF Belt tension n Replace the PF motor n Replace the Main Board

SERVICE REQ. 00010001

o Problem

PF motor out of step - the length of the PF motor internal encoder’s pulse is too long or too short compared to the regular pulse. Self-diagnostic Function: Check in “Inspection: Encoder.”

o Solution

Make sure there is nothing blocking the grid rollers. If that does not solve the problem, check the PF motor encoder connection. If there still is a problem, try the following.

n Check and adjust the PF Belt tension n PF Motor encoder sensor mounting position deviation (See Chapter 5.) n Replace the PF motor n Replace the Main Board

Troubleshooting Outline 72

EPSON Stylus Pro 9500 Revision A

SERVICE REQ. 00010002

o Problem

PF motor overcurrent - Feedback from the PF motor (IC35) driver’s 10-pin output (sensor signal) indicates that the PF motor’s current is irregular.

o Solution

n Replace the PF motor n Replace the Main Board

SERVICE REQ. 00010003

o Problem

PF in-position time-out - The in-position time is the amount of time the printer waits to make sure the carriage is not moving when the carriage comes to a stop. The rotary encoder is activate for the predetermined “inposition time” and if the encoder sends a pulse, this means the carriage is moving even though it is supposed to be at a full stop, this generates an error.

o Solution

n Replace the PF motor n Replace the Main Board

SERVICE REQ. 00010004

o Problem

CR motor encoder check error The CR motor makes small revolutions clockwise and counter-clockwise . When it turns, the printer checks the encoder output signals to make sure the motor is turning at the correct speed/distance. If the encoder doesn’t send the correct signal or output data, an error occurs.

o Solution

Make sure there is nothing blocking the carriage. If that does not solve the problem, check the CR motor encoder connection. If there still is a problem, try the following.

n Check the plastic step ruler for soiled areas, obstructions, and damage n Replace the encoder sensor n Replace the CR motor n Replace the Main Board

SERVICE REQ. 00010005

o Problem

CR motor out of step - the length of the CR motor’s pulse is too long or too short compared to the regular pulse.

o Solution

Make sure there is nothing blocking the carriage. If that does not solve the problem, check the CR motor encoder connection. If there still is a problem, try the following.

n Check the plastic step ruler for soiled areas, obstructions, and damage n Encoder sensor mounting position deviation (See Chapter 5.) n Replace the encoder sensor n Replace the CR motor n Replace the Main Board

n Send a different print job to make sure the error wasn’t due to electrical

noise or bad print data.

3.1.3 General Errors

This section describes the errors that can be solved by the user.

INK LOW

o Problem

An ink end sensor has detected that the corresponding ink cartridge is almost empty (ever ink cartridge has an ink level gauge). It is possible to print about 100% duty on B1 size paper with the remaining ink, but the cartridge should be replaced as soon as possible. If you re-install an ink cartridge that was detected as being in a “Near End” state, the status will immediately go to “Ink Out”. Only install new cartridges.

o Solution

Replace the ink cartridge.

CHECK

PO IN T

If for any reason you replace an ink cartridge before it reaches the ink-low or ink-out state with a new ink cartridge, you need to reset the ink counter using the control panel and Maintenance Mode 2.

Troubleshooting Outline 75

EPSON Stylus Pro 9500 Revision A

PAPER OUT

o Problem

n Paper is not loaded. n The rear edge of roll paper has been detected. n The print job using cut sheets is finished or the rear edge of cut-sheet

paper has been detected.

o Solution

n If paper has run out, remove the printer paper and load new paper. If

print data remains in the printer, the data will be printed.

n If this error occurs even though paper is properly loaded, there may be

something on the P-Rear sensor’s surface. Clean the sensor’s surface (hole in the Paper Guide, Upper) with a clean, dry cloth.

CAUTION

Use a clean, dry cloth when cleaning sensors; never use a wet cloth or soap.

LOAD XXX PAPER

o Problem

The selected paper source (according to the remote PP command) and the paper type selected on the control panel do not match.

o Solution

Load the correct paper or change the panel setting to match the type of paper loaded in the printer.

n If this error occurs even when the lever is down, in the Lock position,

there may be a problem with the Paper Release lever sensor. Check the sensor operation, sensor connection, and board.

PAPER JAM

o Problem

A paper jam occurs when during printing, paper feeding, or paper cutting the carriage is not able to move properly (due to paper catching on some part). The printer determines a paper jam has occurred if the P-Front sensor and P-Rear sensors are in the “on” state but the CR motor is out of step or has overcurrent.

o Solution

n Check if the appropriate spindle is being used for the paper.

• Mat synthetic paper roll: Use of a high tension spindle is recommended.

• MC image paper roll: Use of a high tension spindle is recommended.

n If the paper that is involved in a paper jam is removed, the message

“Please start again.” will be displayed, so turn the printer’s power on again.

n If the paper jam occurs again after the paper has been removed, check

around the carriage mechanism to see if there is some kind of obstruction to carriage movement. If there is some kind of foreign object, etc. present, remove it.

COVER OPEN

o Problem

LOAD PAPER

o Problem

While paper is loaded, the Paper Release lever was pushed up to the Release position.

o Solution

n Make sure paper is loaded properly and push down the Release lever

Front cover is open.

o Solution

n If the cover is opened during carriage operation or during a cleaning

operation, etc., all mechanical operations are halted, so if it is left open for a long period of time, it could have a bad influence on the print head. Therefore, the cover should be closed rapidly.

to lock the paper in place.

Troubleshooting Outline 76

EPSON Stylus Pro 9500 Revision A

n If this error occurs when the left and right sides of the front cover are

closed securely, the mounting position and operation of the cover open detection sensor (interlock switch) should be checked.

CAUTION

n If the cover is opened during printing, the affected

pass will not be reprinted after r ecovery, so there will be marks left on the printout at the affected portion.

n If you would like to open the cover during printing,

press the “Pause” button to interrupt the printing operation, then open the cover . However, even in this case, since the printing times will be different in the area before and after the place where printing was interrupted, irregularities in the print quality (irregular color) will occur.

PAPER NOT CUT

o Problem

The paper that was supposed to be cut was not cut completely, or the paper was cut but is still in front of the P-Front sensor.

o Solution

n Remove the cut paper if it is on or near the Front Cover and Lower

Paper Guide.

n Replace the cutter if it is worn out. n If miscutting is occurring due to deviation in the paper cutter position,

carry out adjustment of the paper guide L installation position, adjustment of the cutter mounting position, checking of the paper cutting position and adjustment of the CR cover height. See Chapter

PAPER NOT STRAIGHT

o Problem

This error occurs when the printer detects the front and rear edges to be skewed (the paper is loaded at an angle/slant) by more than 3mm. If the printer prints on paper that is loaded at a slant, the printer may print outside of the printable area and may fire ink onto the platen. If this happens, the next sheets loaded in the printer may have marred reverse sides.

o Solution

n Remove the paper loaded in the printer and properly reload it

according to the instructions in the user’s guide.

n For roll paper, the edges of the paper may not be lined up; (remove the

paper) and carefully squeeze the sides of the roll to make sure the edges are lined up and flat.

RELOAD PAPER

o Problem

This error occurs when, A) The front edge is loaded too far and the paper is not in the loading

position after it is reverse fed. B) The paper was loaded in such a way that the left and/or right edge is

out of the printable area (due to mis-loading or because the paper is too wide).

C) After printing has finished, the right or left edge is out of the area where the cutter can cut the paper.

D) The loaded paper was longer than the selected paper, and the paper was not fully ejected. (For example, roll paper is loaded in the printer but cut sheet is selected on the control panel.)

E) A cutter error occurred after the paper was ejected.

Troubleshooting Outline 77

EPSON Stylus Pro 9500 Revision A

o Solution

n A)~C) above

Properly reload paper. If the front edge of the paper is not straight and clean, cut the paper.(If the paper is pulled back and set 60 mm or more from the criterion line (hole), it will exceed the permissible amount of backfeed (200 mm from the paper edge detection sensor position and result in an error.)

n D)~E) above

Cut of the section of the paper that has ejected/protruded and reload the rest of the paper. For paper that is automatically cut, lift up the Release Lever (the “Load Paper” message appears), fix the position of the paper, and lower the Release Lever. If you select you “Roll Paper/ Auto Cut” setting, you can cut off the protruding part of the paper using the Cut button.

n If the error recurs even after reloading the paper, make sure the paper-

end sensor on top of the carriage is installed correctly and working properly.

PUSH LEVER DOWN

o Problem

The printer is not able to continue paper feeding/initializing, printing, or ink sequencing because the Release lever was moved to the Release position. Or, the printer cannot begin printing because the lever is in the release position.

o Solution

n Push down the lever. However, if printing was interrupted because the

lever was pushed to the release position and the paper shifted, the print job may be marred.

n If the lever is down and this error still occurs, check the Release-Lever

position sensor.

COMPARTMENT OPEN

n Push the I/H lever down to the lock position. n If the lever is down and this error still occurs, check the lever position

sensor.

INK OUT

o Problem

One or more ink cartridges have run out of ink, a near-end cartridge has been reinstalled, or an unsupported ink cartridge has been installed.

o Solution

n Replace the empty ink cartridge.

CAUTION

When replacing an empty ink cartridge, always repl ace it with a new ink cartridge; otherwise the printer cannot determine how much ink remains.

n Make sure the ink cartridge is the proper type of cartridge for the

printer and the proper color for that slot.

n If the proper cartridge is installed and this error still occurs, check the

Ink-End sensor and the Ink ID sensor.

NO INK CARTRIDGE

o Problem

An ink cartridge is not installed or is not installed properly.

o Solution

n Install the proper ink cartridge in the empty slot.

CAUTION

When replacing an empty ink cartridge, always repl ace it with a new ink cartridge; otherwise the printer cannot determine how much ink remains.

o Problem

An Ink Holder (I/H) compartment door is open.

o Solution

n If the proper cartridge is installed and this error still occurs, check the

Ink-Cartridge sensor.

Troubleshooting Outline 78

EPSON Stylus Pro 9500 Revision A

REMOVE PAPER

o Problem

Printer cannot perform cleaning because of thick paper. (The printheads are too far away from the Cap Assembly.) This error occurs under the following conditions.

n Thick paper is loaded when the periodic/timer cleaning operation is

supposed to begin.

n The printer attempts to print on thick paper when the periodic/timer

cleaning operation is supposed to begin.

n You turn on the printer and the thick paper is loaded. n You attempt to perform a manual cleaning operation when thick paper

is loaded.

o Solution

n Remove thick paper and push the Release lever down. (This causes

the cleaning to operation to start and “Wait” appears on the display.) After the cleaning operation is finished, “Paper Out” appears. Load thick paper.

OPTION I/F ERROR

o Problem

An unsupported Type-B interface card is installed.

o Solution

Turn off the printer, remove the unsupported card, and install a supported card.

3.1.4 Troubleshooting Based on Your Printout

This section describes the conceivable print quality problems that may occur with this printer and the troubleshooting points for those errors.

Table 3-4. Print Quality Problems

Description Refer to

Dot missing page 79

Uneven printing/poor reso lution page 80

Smudged or marred printout on front side page 80

Smudged or marred printout on reverse side page 81

White/black banding page 81

DOT MISSING

When the printer is not used for a long period of time, the ink in the nozzles can dry up and clog the nozzles. Clogged nozzles cannot fire ink and cause the dot-missing problem in printed documents. If the printhead nozzles do not clear after attempting multiple cleaning operations, check the following points.

1. If there is no output at all or only some the colors print, check the ink valves on either side of the printer I/H Assemb lies to make sure th e knobs are s et to “O pen” . (A lso, see the user’s guide or printer software.)

2. Perform ink charging again Select the “Cleaning” function on the control panel’s Self-Diagnostic menu. This sends a lot of ink into the heads and forces out the old ink that is clogging the nozzles.

CAUTION

Do not charge ink too often as this operation consumes a lot of ink. Each head consumes about

94.43ml per operation.

Troubleshooting Outline 79

EPSON Stylus Pro 9500 Revision A

3. If the extra ink charge does not clear the clogged nozzles, confirm the following.

n There is no damage to or foreign materials in rubber of the Cap

Assembly

n The Cap Assembly valve is operating normally (if it is not, the Cap

Assembly will not properly absorb ink

n The Cap Assembly retention spring is working properly. n The Cap Assembly retention ink tube is working properly. n The ink tubes and pipes between the ink cartridges and printheads are

properly connected and are not damaged (check the nuts for tightness, the O-rings for warping, and the tubes/pipes for ink leakage)

4. If after following the above steps the printout still shows missing dots, replace one of the parts listed below and check the print out.

n Main Board n Printhead(s)

CAUTION

n Before you uninstall the Main Board or a printhead,

make sure all cables are disconnected. After installing the new board or head, make sure all cables are properly connected; if cable connectors not completely inserted, they can damage circuits or the heads when current is turned on.

n Make sure you replace the correct head, B head or

C head.

UNEVEN PRINTING/POOR RESOLUTION

If printout quality suffers from unevenness, poor quality, or similar problems, check the following.

1. Perform platen gap adjustment Using the control-panel setting or the diagnostic-program function, check the platen gap (bi-directional printing position as well as PG adjustment).

2. If this error occurs only when the user prin ts on custo m or thick paper, (U se the con trol panel paper thickness setting to correct the paper size and the print position (depending on the paper-thickness setting, the location where the ink strikes the paper may change))

3. If after following the above steps the printout quality has not improved, verify the following.

n Head angle adjustment n Head height adjustment

CHECK

PO IN T

When using the “Adj.B (or C) Head Skew” as well as the “Adj:PG Check Height” functions, always perform the Gap Adjustment or Bi-directional Position Adjustment operation.

SMUDGED OR MARRED PRINTOUT (FRONT)

The front, or top, side of the paper can become smudged or marred if it rubs against the printhead surface. If this happens, verify the following.

1. If the smudged area is just around the front or rear edge of roll paper, make sure the margins (top and bottom) are set to 15mm on the control panel. (When printing high-duty print jobs with the top and bottom margins set to 3mm, the high volume of ink can cause the paper to warp and rub against the printhead surface.)

2. If the trouble occurs again, check the following.

n Check if the cap assembly or tension spring has come off.

(If this spring comes off, ink will remain inside the cap and ink adhering around the head nozzle surface will end up adhering to the paper.)

Troubleshooting Outline 80

EPSON Stylus Pro 9500 Revision A

SMUDGED OR MARRED PRINTOUT (REVERSE SIDE)

If the back of the paper is becoming soiled with ink, check the following items.

1. Check if ink is adhering to the paper feed path somewhere and if there is any ink, wipe it off.

n Sub-platen surface n Grid roller surface n Paper guide L surface

2. If ink is adhering to the above parts, the likely cause might be the following, so check it.

n Skewing of the paper during printing (at the point when one page is

finished).

WHITE OR BLACK BANDING

If white or black banding (lines across the page) appear on your printout, try the following.

1. Cleaning

2. If multiple cleaning cycles don’t clear the banding problem, try adjusting the heads as described below.

n Head slant adjustment (B head/C head)

If all the nozzles in the B head and C head are not perfectly lined up, the raster lines will overlap. The unprinted area between one line and the next line (where a nozzle was supposed to fire but missed) is banding.

n Head height adjustment (B head/C head) n Bi-directional print position adjustment n Gap adjustment opening

DISASSEMBLY & ASSEMBLY

CHAPTER

EPSON Stylus Pro 9500 Revision A

4.1 Summary

This section describes the disassembly and assembly methods for the EPSON Stylus Pro 9500. However, full assembly instructions are not given apart from following the disassembly instructions in reverse order, and where special instructions are necessary, check points are provided.

Where “Caution” and “Check Point” notes are given, be sure to confirm these contents BEFORE starting the corresponding procedure. Where adjustment procedures are necessary, “Adjustment Required” notes describe what you need do to. These adjustment procedures are absolutely necessary and are described in detail in Chapter 5, "Adjustment".

4.1.1 Warnings

Before proceeding with any disassembly or assembly work, make absolutely sure of the following.

W ARNING

n The power switch is located at the top of the control pa nel,

and to prevent shock or damage to the printer, always remove the power cable before disassembly or assembly

n For safety reasons, the front cover position, up or down, is

automatically detected by the cover-open sensors which are interlock switches. Do not block or modify these sensors.

n Because the Main Board provides a Lithium battery for

memory backup purposes, you must keep the following in mind when handling the Main Board.

- Be careful to avoid damaging the Lithium electrodes due to short circuits.

- When replacing the battery, make sure the positive/ negative sides are installed correctly

- The battery can become very hot, so be careful when touching it

n Wear protective goggles to protect your eyes from ink. If

ink gets in your eye, flush the eye with fresh water and see a doctor immediately.

n Wear a pair of gloves to protect your hands than the sharp

edge in the printer mechanism.

n If ink gets on your hands, wash them thoroughly with soap

and water. If ink gets in your eyes, rinse them immediately with water.

n If it is necessary to remove external printer parts while the

printer is on to view the internal operations, be very careful around high speed parts such as the carriage fan.

n Keep in mind that the steel carriage drive belt and cutter

blade can be dangerous.

Disassembly & Assembly Summary 83

EPSON Stylus Pro 9500 Revision A

CAUTION

n Before servicing or performing maintenance on the

printer, make sure you have enough space. If you need to move the printer, be sure the space is you move to is safe.

n Because the printer is much heavier than most printers

(about 96Kg for the printer and options), you need to take extra care. If you need to take apart the printer and stand or lift the printer, four people are necessary.

n Ink may leak onto other printer parts or the printer basket

when removing printer parts, so it is recommended to put a sheet or cloth under the printer, especially when working on or near ink-related parts.

n When working on the electrical circuit board, be careful

concerning static electricity, which can cause damage to the board. If necessary, use an anti-static wrist band or similar grounding device to prevent static electricity buildup.

n When removing/re-inserting the flat-cable (FFC) from/to a

connector, make sure to pull/insert the cable straight. Otherwise, internal contact of the connector may be damaged and this causes a short-circuit to destroy the electrical circuitries.

n The cutter blade is very hard and can damage or scratch

printer parts, and it can also be chipped or damaged. Be careful when handling or replacing the cutter.

4.2.3.1 Replacing the Waste Ink Pads

To keep the printhead clean and maintain quality, the printer drains waste ink away from the printhead surface and nozzles into the Waste Ink Boxes. Once a predetermined amount of waste ink has been drained into one of the Waste Ink Boxes, the printer displays the “Maintenance Call 0100” or “Service Call 00000100” to indicate one of the boxes is full and needs to be replaced.

CAUTIO N

This manual only describes the repair and replacement procedures for parts that can be serviced on site. Theref ore, only perform repair or replace procedures that are described here. Other service procedur es can o nly be done at the factory and can become permanent fatal errors if not done correctly.

When the printer’s useful life counter indicates the ink pads need to be replaced, the following parts all need to be replaced at the same time.

n Waste Ink Pads, Left & Right n Pump Assembly n Cap Assembly n Head Cleaner n F Box, Left & Right

4.2.3.2 Replacing the Printheads

CAUTIO N

ADJUSTMENT

REQUIRED

The printer uses two printheads, B Head and C Head, and although they are similar you need to make sure you do no mix the heads. One is for dark inks and the other is for light inks. Therefore make sure you prepare and install the correct replacement head.

n B head (Dark system head)

F055040: “Printhead, IJ192-OAD”

n C Head (Light system head)

F055050: “Print Head, IJ192-O AE” Compared to the B head, the above C head is a higher precision head. Therefore, when banding claims occur, it is recommended that this head be used to handle the problem.

When replacing the printheads, the following adjustment procedures are required.

n Self-diagnostic Function / Adjustment (Adjust the

inclination of the left and right heads, adjust the right head height, Adjust the Bi-D, Adjust the Gap.) page 167

n Head unit counter reset. Refer to page 200 n Carriage cover height check. Refer to page 208

Carriage lock release

Figure 4-20. Carriage Lock Release

1. Turn the ink valve knob located on the sides of the I/H Holders to the “Close” position, or lift up the I/C Holder lever. Both operations perform the same function of shutting off the flow of ink through the ink tubes.

2. Open the Front Cover.

3. Remove the Maintenance.(See 4.2.1.1)

4. Optional: Remove the H Top Cover.(See 4.2.1.1) This is an extra step during removal and re-installation, but it provides more light and room.

5. Manually release the Carriage Lock and move the carriage away from the capping position.

6. Disconnect the flat cable running from the “CR Board Assembly” mounted on top of the carriage from the affected print head.

7. Remove two screws (CB M3x6), and remove the carri age cover

8. Remove the 1 screw (CP(W2) M3 x 6) and remove the “Damper Holder.”

9. Take out the damper assembly connected to each print head. At this time, it is easier to remove the damper assembly if a flat blade screwdriver or similar implement is inserted between the damper positioning material and the bottom surface of the damper and is used to pry it up.

CAUTIO N

10. Using needle nose pliers, etc., remove the compression spring that is fitted in the print head. (9.9)

If you grasp the side of the damper, the ink that is filling the inside of the damper will leak out, so absolutely do not apply any force to the sides.

11. After removing the 1 screw (CB M3 x 6) and the “H spacer,” remove the print head from the carriage briefly.

12. Take out the flat cable that is connected to the back of the print head and remove the print head.
