*1 The return side means the twisted pair return and is conn ected to the signal grou nd 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.
*2 All the interface conditions are TTL level standard conditions. The rise and fall time of each signal is 0.2 _s or less.
*3 For details on the timing of each signal, see the “Data Transmission Timing” diagram in the figure below.
*4 There must not be any data transfer with disregard of the /ACKNLG or BUSY signals. (Data transfer to this printer must be performed when/ACKNLG is confirmed or when BUSY is in the “LOW” state.)
*5 If appropriate character codes are set for DATA 1~8 of the interface connector (as opposed to “1” for GND open and “0” for short circuit), and BUSY and /STROBE are connected, an external device is not used and a printing test can be performed, which includes the interface circuits.
*6 The printer is in the following states when the PE signal line enters the A ssert state (“L” Level).
• Out of paper error occurring (ST:00 ER:06 state)
• Other paper errors occurring (ST:00 ER:0E, 12, 13, 14, 15, 16 state)

1.3.4 Supplementary Items

RECEIVING BUFFER OPERATION
When receiving data via the parallel interface or 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.
If 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. When the available capacity becomes 1K-byte or higher, reception at 1 byte/sec. is resumed.
INTERFACE SELECTION
It is possible to switch between the manual fixed selection function or auto selection function to select the parallel, USB or optional interface.
However, if the USB interface is connected, it becomes impossible to use the parallel interface, For this reason, only one of these interfaces, either the parallel interface or the USB interface, can be connected to the host computer and they cannot be used in combination.
o Manual Fixed Selection:
One interface, the Parallel/USB interface, or the optional interface, can be selected.
o Auto Selection Function:
After the power is turned on, the interface from w hich 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:
• When an interface other than the parallel/USB interface is selected, the parallel interface enters 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 means that the 1284 interface cannot respond. Therefore, a hos t computer requesting reverse transmission must first check LH. In addition, the USB interface is in a state where it sends a NACK response and refuses to receive data.
• When an interface other than the optional interface is selected, the OFF-LINE bit is set in the Main Status Register (MNSTS).
• After the printer has been initialized, or when in the idle state (with no interface selected), with the parallel interface in the ready state, the USB interface in the state where it does not send a NACK response, set the OFF-LINE bit of the Main Status Register (MNSTS) for the optional interface.
• The 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 mode.
INITIALIZATION
This printer is initialized by the following three methods.
1. Hardware Initialization This is the method of initialization that is carried out when the power is turned on. <Initialization Operation>
• Printer mechanism initialization
• Input data buffer cleared.
• Print buffer cleared.
• Setting of default values.
2. Software Initialization Initialization is performed by executing the Initialize command (ESC@). <Initialization Operation>
• Print buffer cleared.
• Setting of default values.
3. Panel Initialization This is the initialization operation when the Pause button is pressed for 2 seconds or longer, or when the /INIT signal is input. <Initialization Operation>
• Paper is ejected (in the case of roll paper, the printed portion is skipped and if the panel setting’s paper select is set on Auto cut, the paper is cut, and if the cutter is OFF, the

*6:Through this panel setting, switching betwe en a top, b ottom left a nd righ t roll paper m argin of
3 mm, a top, bottom, left and right margin of 15 mm and a top and bott om margin of 15 mm and a left and right margin of 3 mm can be done. This setting is effective only with roll paper. Cut sheet paper is no t influenced. This setting does not change the image size, but changes the margin only. (1)Margin Setting = 3 mm
The vertical line and horizontal pri nt ing position is the same as the logical paper size.
(2)Margin setting = 15 mm or Vertical margin setting = 15 mm
The vertical line and horizontal l in e printing position becomes 12 mm wider than the logical paper size in the top, bottom, left and right margins or in the top and bottom margins only.
*7:By setting the paper width sensor on OFF, occurrence of the error “set the paper correctly” is
suppressed if the paper width detection is not complete d norma lly. Printing is executed wi th the following settings.
• The paper’s left edge position becomes the guide mark position on the paper guide.
• The printable area becomes th e pr intable area specified by the command. If printing is being done on tracing paper, etc., which has a low reflection rate and cannot be
detected, this setting is used. Through this 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 fai ls, it results in an error.)
*8:If the paper skew sensor is set on “OFF,” the occurrence of t he error “Paper is skewing from
the paper feed path” is suppressed an d pri nti ng continues. By this setting, even if the printed image overflows the edge of the paper as a result of the paper skewing from the feed path, the printer will not inform the user of the error, so the user must take responsibility for the possible consequenc es.
*9:By running this mode, all the value s set from the panel are returned to the default values.
*2:By running this mode, the cutting line print mode can be set. The setting contents are
equivalent to the setting for turning Print Horizontal Line ON (AC 02H 00H 00H 02H) in the auto cutting state. The printed cutting line’s type is a solid line.

The setting method is shown below.
1) Set A1 roll 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: If you are car rying out gap a djustment printing, pri nting paper with the
following lengths is necessary.
• When selecting and printing 1 pattern: Approx. 7 cm.
• When selecting and printing all printing patterns (6 patterns): Appro x . 40 cm.
NOTE: Always, in printing of each pattern, 1 block of 15 patterns is printed 6
times. Pattern No. 8 of the 15 patterns in one block shows the current setting value.
The correction values set by the above adjustment are saved in NVRAM. The purpose of maintaining the paper thickness (set during the adjustment) is for the sake of making corrections in 0.1 mm units with respect to the paper thickness from the paper thickness setting command PH.

CARRIAGE MOVING UNIT
IIn place of the carriage holding system in which 2 CR guide shafts extending in the column direction were used, as in the previous models, a structure with the carriage mounted via multiple rollers (bearings) on a CR guide rail made from a square extruded aluminum pipe is used. Steel rails are incorporated in the roller contact and running surface, and the result is a reduction in friction in the direction of movement, reduced vibration and improved durability.
NOTE: The screws used to fasten the CR guide rail should not be taken out and
the carriage should not be remo ved. These are adj usted and as sembled to the nearest 1/100 mm at the factory.
A DC motor is used for the CR motor and the slit in the timing fence affixed on the bottom of and parallel with the CR guide rail is read by the encoder sensor mounted on the carriage (linear encoder system), and this signal is compared to logical control values in the control circuit on the C299 MAIN board , which carries out feedback speed control. Through this control, high print precision is maintained.
Drive transmissions from the CR motor to the carriage use the easy-to-maintain, durable timing belt.
The sensors used in the carriage moving unit are described below.
o CR_HP Sensor
This is a transmissi ve pho tose nsor which is moun ted o n the ri ght end of t he pri nter mechanism and detects the entry position of the flag (projection) provided on the carriage as the carriage moving home position. Outputs from this sensor are “OFF” in the HP range and “ON” outside the HP range.
o Linear Encoder
This encoder is mounted on the back of the carriage and outputs pulses (2 channels) corresponding to the position of the slit on the timing fence that is incorporated into the CR guide rail which are used for C R motor servo co ntrol and PTS (Print Timing Signal) generation. The resolution is 1/180 inch.

PLATEN GAP ADJUSTMENT UNIT
In order to maintain the print precision, it is necessary to maintain the carriage (= head) mounting position so that it is always a constant distance from the surface of the paper.
In this printer, the print head nozzle surfaces and platen surface are variable mechanisms so that the gap between the paper printing surface and the head nozzle surface can be kept constant.
The carriage has a 2-body construction with a sub-carriage on which the print heads are mounted attached to the carriage which forms the base. The sub-carriage moves in the vertical direction with respect to the paper surface. This movable system uses a cam. The sub-carriage to paper surface distance changes linearly from the cam (= PG) home position.
Operating Principles Print Mechanism Components 62
Page 63
EPSON Stylus Pro 7500 Revision c
When the carriage is in the HP p osition ( = right end) , the pump motor and the g ear mounted on the cam shaft engage, the motor’s rotation (reverse) drives the cam and the sub-carriage is positioned at the proper gap position.
In order to maintain the distance between the print head nozzle surfaces and the paper, the thicknesses of the paper used are classed into 3 levels, PG small (1.3 mm) / Medium (2.2 mm) / and Large (2.7 mm) when carrying out PG setting.
Carriage
NOTE: It is also possible to set the PG value manually. For details, see the item
“Platen Gap” in 1.6.1, “Printer Setting Menu.”
CR Guide Rail
The print heads consists of two heads, the dark type ink (B) head and the light type ink (C) head.
Ink viscosity is influenced by temperature. In order to control the ink discharge rate and discharge volume so that they are the same even if the temperature changes, each respective print head has a built-in thermistor for detecting the head temperature.
NOTE: The B and C print heads used in this printer are the same model No. as
those used in the Stylus Pro 5000/9000.

o HD-SLID (Head Gap Home Position Detection) Sensor
This sensor detects the mechanical home position when the position of the sub­carriage (head height from the paper surface) on the carriage undergoes change. A reflective type photosensor is used and the position of the flag on the gear mounted on the camshaft is detected. When the sub-carriage has dr opped down to its lowest

position, the sensor is configured to go “O ff”, and during a sens ing oper a tio n, and the point where the head changes from movi n g up to movi ng down and t he sens or output switches from “OFF” to “ON” is recognized as the mechanical home position.
o P_EDGE (Paper Width Detection) Sensor
This sensor is mounted on the left rear of the carriage. It detects the left and right edges of the paper and carries out paper width recognition and skew judgment. A reflective type photosensor is used and the paper edge (presence or absence of paper) is judged with the sensor output in the form of an 8-bit A/D converted value.
NOTE: It is possible to turn this sensor off in 1.6.1, “Printer Sett ing Menus.”

The following sensors aid in the paper feeding process.
o P_FRONT sensor
This sensor is attached to the subplaten and is an optical (photo-reflective) sensor. This sensor detects the front edge of the paper after paper has been loaded but before it is set and ready to print.
o P_REAR sensor
This sensor is attached to the Upper Paper Guide and is an optical (photo­reflective) sensor. This sensor detects the rear edge of the paper and detects the front edge when the paper is first loaded in the paper path. The position of this sensor is stored in EEPROM.
o P_THICK sensor
This optical sensor physically gauges whether the paper falls into the normal/thin category or the thick category.

o Release Sensor
A transmissive photosensor is used and it is mounted on the H top cover rear side (right). It is constructed so that the sensor detection lever is linked to the paper support lever’s operations. When the paper support lever is in the forward position, it is in the set state (Fixed position). Also, when the release sensor is in the “Release” state, the CR motor and PF motor are stopped.

2.2.3 Cleaning Mechanism

The cleaning mechanism in this printer is compatible with the cleaning mechanism in the Stylus Pro 5000/9000. The cleaning mechanism is located on the right side of the printer. The waste ink from the cleaning mechanism is channeled to the waste ink pad in the lower right side via 2 thin tubes and 1 pipe. (See the figure below.)

EPSON Stylus Pro 7500 Revision c
The cleaning mechanism components are installed above the subframe and some are fixed on the main frame as shown below.
o Pump assembly (head cleaner)
When the head is in the capped position (valve closed), the pump motor creates a vacuum that sucks ink from the nozzles. This is used for removing ink from the nozzles and nozzle plate, initial ink charge, as well as cleaning. The waste ink flows through two small tubes to the waste ink pads.
o Head cleaner
The head cleaner has felt on one side and rubber on the other, and is used to wipe or rub off ink and foreign materials from the nozzle surface.
o Pump motor
Clockwise rotation = pump assembly drive for cleaning and so on Counter clockwise ro tation = pla ten ga p adjustm e nt
o Cap assembly (one pad for each printhead)
When not printing, the printheads (should) rest on the cap assembly to make sure the nozzles don’t clog. Also, the printhead s are in the capped p osition during ink charging , cleaning, and so on.
o Flushing box
Flushing (dummy printin g) is perform e d over the flushin g box , and the flushe d ink flows through the large diameter tube to the waste ink pads.
o CR Lock Mechanism
If the carriage moves from the printable area to beyond the capping (CR_HOME) position to the right, the carriage moving prevention lock is engaged. The CR lock mechanism uses the cutter solenoid in common. When the cutter solenoid goes ON in the capping position, the CR lock is released.
NOTE: The “Ink System Terms” used in the above text are explained in the
following table.

• This is the carriage stop position when the power is Off.
• The time when the carriag e is in th e sta ndby p osit ion (h om e p osit ion ) with t he power On and with no paper loaded and no print data to print.
• This is the operation where the head is filled with ink for the first time. When the first ink cartridge is inserted (after all 6 colors have been inserted), the ink initial filling operation is performed automatically.
• The initial filling flag is set when the printer is shipped from the factory, then after this operation, the initial filling flag is reset. The initial filling flag is also set after the “Inter-User Transport Mode” is run.
• In order to prevent the viscosity of the ink inside the head nozzles from increasing, the ink inside the flushing box is flushed out.
• Flushing is done when paper is set, when printing from the standby state, during continuo us printing, during paper Eject, during paper cutting, etc.
• After ink is sucked up, the remaining ink inside the cap is sucked up and the ink adhering to the head no zzle surface is removed.
• Through flushing, etc., the ink that has accumulated in the cap is sucked up and discharged.
• After ink is sucked up, any dust, etc. adhering to the head nozzle surface is removed and tight fitting of the cap is assured.
• Any ink or dust, etc. that has adhered to the head nozzle surfa ce after ink suction is removed, and the no rmal ink spray state is recovered.
The head nozzle surface is wet with a tiny amount of ink, then the head nozzle surface is cleaned off, with any tightly adhering dirt, etc. being removed, thus assuring that the cap will fit tightly.
In order to prevent the ink viscosity from increasing while it is being kept, a rubber cap is placed over the prin t head nozzles when entering a shutdown operation.

2.2.4 Ink Supply Mechanism

In this printer, there is an ink holder on the left side (I/H) where 6 ink cartridges, one of each color, (from the left), K, C, M, Lc, Lm and Y, are installed. A projection and unique markings are placed on each color ink cartridge case to prevent wrong insertion so that the wrong color cartridge is not inserted and so the cartridge is inserted in the right direction.
NOTE: This printer does not use the ink valves which are used in the Stylus Pro
9000 and Stylus Pro 9500. Therefor e, i f you are tra ns por t ing t he pr int er, in order to prevent ink from leaking from the ink channel, all the ink should be discharged by running the Inter-User Transport Mode, then carrying out parking and transport.
Ink cartridge holder
o Ink Cartridge (I/C) Detection Sensor
This sensor uses a microswitch to detect when the ink cartridge is installed. I/C Installed state (Present):Switch closed I/C Not Installed state (None): Switch open
o Ink End Detection Sensor
This sensor uses a mechanical switch to detect the amount of ink remaining in each ink cartridge. Through a detection flag which changes according to the amount of ink remaining in the ink pack inside the ink cartridge, the switch is turned ON or OFF, and thus carries out detection.

COVER SENSOR
In order to detect whether the front cover on the lower front of this printer is open or closed, a cover sensor is mounted on the printer on the left side where the front cover opens and closes.
This sensor carries out control of operating and stopping of the CR motor and PF motor drive circuits via the C299MAIN board’s logic circuit after detecting the cover’s status. This control is the same when the paper support level is in the release state.

2.4 Power Supply Board Summary

Depending on the printer model, either 100V AC or 220V AC is supplied to the printer when the printer is plugged into an liveoutlet.
The power switch consists of a secondary power switch system. A secondary power switch system is a system where the power supply board operates with a minuscule power level as long as the power cable is connected, even when the power switch is turned off.
NOTE: The power supply board is configured so that it does not stop
immediately even after the power switch is turned Off, but after the ink system’s end sequence has been perfor med, the power goes Off. Therefore, the printer should not be operated by turning a power supply tap switch On and Off.
The power supply board is equipped with an overcurrent protection fuse for protecting it against overcurrent. The fuse rating is shown in the following table.
Table 2-5. Fuse Rating
Input Voltage Range [V AC] Fuse Rating
100V AC ± 10% 125V AC/6.3A
The C299MAIN board has three control signals, described in detail in the table below.

• If this terminal is shorted, the drive system power supply, 28 V DC and 42 V DC, becomes active.
• If this terminal is cleared (= L), the drive system power supply, 28 V DC and 42 V DC, becomes 0 V DC.
• The 5 V DC powe r supply is not co ntroll ed by this terminal.
The power switch goes On, the power supply board unit starts and each output becomes active. Afterward, the “H” signal is sent to the C299MAIN board.
The power switch goes Off, and the each output of the power supply board unit becomes inactive, or if the input voltage drops belo w the rated voltage value, the “L” signal is sent to the C299MAIN board.
This is connected to the panel unit’s power switch.
• When the switch is in the On state, this terminal is shorted. the power supply board changes to the operating state.
• When the switch is in the Off state, this terminal is cleared. After waiting in the operating state for 10 plus seconds and up to several minutes, the power supply unit goes off.

3.1 Outline

This section explains procedures for rapid and efficient troubleshooting if trouble occurs in the printer.

3.1.1 Introduction

First of all, when performing troubleshooting, the following basic parts should be checked.
1. Look in the printer for any foreign matter and make sure there is nothing there to hinder normal operation.
2. Carry out printing by setting the printer in the “Pause” state, then press the [SelecTyp e] button 2 times. Next using the [Paper Feed] switch in the “TEST PRINT MENU,” select “ATATUS CHECK”, then press the [Enter] switch and print.
From the status sheet, you can check if the cause of the trouble is that the printer (either the printer unit itself or some major unit) is at the end of its service life, and check the user inherent panel settings, etc.
3. There should be no market soiling of the outside or the inside of the printer. If it is extremely soiled, carry out cleaning.
4. Each of the units and parts in the printer should not be missing or damaged, and should have the normal shape and configuration.
5. Each of the harnesses should be undamaged, and s hould be correctly connected to the relevant connector (perpe nd icula rly and in the correct dir ectio n).
9. As necessary, initialize the NVRAM on the C299MAIN board (return the individual customer settings and panel settings to the factory settings).
Carry out initialization by executing “INIT. NVRAM” from the “CLEAR COUNTERS MENU” in “Maintenance Mode 2.”
CHECK
PO IN T
CAUTIO N
When disassembling the printer, turn the printer’s power switch Off, then after making sure that the panel display is off, pull out the power cable from the outlet and disconnect the interface cable.
1. Only the specified printer tools should be used so as to maintain the printer’s quality.
2. Only the specified lubricants and adhesives should be used.
3. The specified adjustments should definitely be carried out.
6. Each cam and gear in the printer mechanism should have no uneven wear or be overly worn, and the combinations should be correct.
7. Each type of rubber roller in the printer mechanism s hould be cleaned and it should be ascertained whether the cause of the trouble is because of dirt or due to some other cause.

WARNINGS

Warning messages appear on the LCD display to warn users that a problem may occur. The printer can still print and there is no effect on print quality; h owever the m essages do not g o away until the possible problem is taken care of or the printer enters the correspondi ng error condition. For example, the Waste Ink Pads Near Full message will remain until the pads are replaced and the counter is reset or until the pads become full and the printer enters an error state.

Recovery Replace the old ink cartri dge with a new one.
The LED indicator for the ink cartridge that is low flashes.
If the standard 100 cc ink cartridge is installed: The printer detected that the soft c o un ter for o ne of th e ink cartridges was at Near-End. When the soft counter’s Near-End si gnal is generated, it means that the cumulative number of dots is counted by software, and that the remaining amount of ink has been calculated to be less than 10%. After Ink Low is displayed, it means, as a cri te r io n, that the area of an A1 sheet can be printed with 100% duty, but the ink cartridge should be replaced as quickly as possible.
When replacing an ink cartridge, a new cartridge which is full of ink should be installed. (A partially filled ink cartridge that has been removed should not be installed a second time.) If this is not strictly observed, the correct operation of the r e maining ink indica tor cannot be guarante ed.
If the large capacity 200 cc ink cartridges are in st alled: The printer detected the Near-End signal for one of the i nk cartridges. The Near-End state is detected by the pos iti on of the sensor plate inside the cartridge, and judgment made. After Ink L ow is displayed, as a criterion, it means, as a criterion, t hat the area of an A1 sheet can be printed with 100% duty, but the ink cartridge should be replaced as soon as possible. When replacing ink cartridges, a new cartridge which is full of ink should be installed. (A partially filled ink cartridge that has been removed should not be installed a seco nd time.) If this is not strictly observed, the correct operation of the r e maining ink indica tor cannot be guarante ed.
CHECK
PO IN T
If it is necessary to replace the ink cartridges before Ink Low or Ink End is detected, and when replacing all the ink cartridges with new ones, the counters should definitely be reset. Reset the counters by “Maintenance Mode 2” -> “Counter Initialization Menu” -> “Ink Initialization.”

There was a paper recognition error or cut sheet feeding error, which can happen under the fol lowing conditions:
1) The user loaded the leading edg e of the pa p er too far into th e prin ter. Th e printer can only reverse feed the paper a set distance, and if the paper is loaded too far, it will not reverse feed far enough.
2) The printer detected that the paper was loaded outside of the printable area/carriage path.
3) After printing, the printer detected that the paper is outside of the cutting area/carriage path.
4) The printer detected that the cut sheet loaded in the printer is too long/ unsupported an d could not be fully ejected. This may occur if roll paper is loaded but the control panel is set to cut sheets.
5) This error may occur after a Paper Not Cut error. 1-3 above) Correctly set the paper as described in the user’s guide. If the
front edge is not clean and straight, cut it evenly. 4-5 above) For roll paper cut off the section of the paper that has been
ejected and properly reload the paper. For cut sheets eject the remaining paper and select Shee ts on the control panel or load supported pa per depending on the cause of the error.
If after correctly reloading paper the same error occurs, check the operation and connection of the P-EDGE sensor located on the carriage.

n
If the cap assembly has faile d. (The tens ion s pr ing has com e off, th e cap rubb er is damaged, etc.)
n
If the pump unit has failed. (The tubes are crushed, etc.)
b) If the trouble occurs with a specific ink color:
n
Abnormal connections between the ink cartridge, ink holder, tube, damper, print head. (Fastening nuts loose, or the O-ring deformed or damaged, causing ink to leak, etc. could occur.)
n
Print head failure Left side (B Head) Black, Cyan, Magenta Right Side (C Head) Light Cyan, Light Magenta, Yellow

DOT MISSING

If the printer is kept for a long time without being used, the viscosity of the ink on the nozzle surfaces of the print heads, and in the nozzles themselves, increases, and may cause skipping of dots during printing. After cleaning, (clean several times), if the printer still doesn’t recover from skipping dots, the following points sho uld be checked.
1. After executing the “Inter-user Transport Mode,” set the “Transport Liquid Cartridges (x 6 cartridges)” in place of ink cartridges and carry out initial filling. (The ink passages will be completely cleaned by the transport liquid.) After initial filling with the transport liquid, discharge the transport liquid from the printer in the “Inter-User Transport Mode.” After that, set new ink cartridges and carry out initial filling, then carry out “Nozzle Check Pattern Printing.”
CAUTIO N
2. If the operation in “1” fails to bring recovery, check the following points. a) If trouble occurs in all the ink colors:
n
Initial filling causes a large amount of fluid to be discharged into the waste ink pad, so the “Waste Ink A,” “Waste Ink B” and “Cleaner” counters will show considerable consumption. (approximately 10%).
Are the print heads and cap assemblies sealed during ink filling?
c) If the trouble still has not been recovered from with the items up to this point, replace the following electric system related parts and check again.
n
Check the connections to the CR cable (FFC long) and if there is any damage to it or not.
n
Check the connections to the head cables (FFC short; x 2), and if there is any damage to them or not.
n
The C299MAIN board.
CAUTIO N
n If you replace the C299MAIN board or the print heads, the
connection state of the connection cables (FFC) should be checked. Particularly in cases where the connector is inserted at a slant, etc., when the power is turned on, it could cause destruction of the circuit and the insides of the heads, so sufficient caution should be exercised.
n During head replacement, care should be taken not to mistake
the B head and C head.
Troubleshooting Troubleshooting Based on Your Printout 93
Page 94
EPSON Stylus Pro 7500 Revision c

UNEVEN PRINTING/POOR RESOLUTION

If the print quality is abnormal (uneven printing, diffused image, etc.), the following items should be checked.
1. Adjust the gap Using panel settings or the self-diagnostic function, carry out gap adjustment (“round
trip print position adjustment” and “gap adjustment”).
2. If the trouble occurs only when the user is using a specific type of paper (thick paper), carry out “User Paper Setting” using the panel setting procedure. (By setting the information concerning the thickness of the paper the user is using and correcting the print position (correction of changes in the position where ink hits the paper surface due to differe nce s in pape r thickn e ss), av oid influe n cing the print position.)
3. Try changing the Bi-D offset #1 (speed priority) / #2 (quality priority) correction values in [Maintenance Mode 2].
4. If this trouble occurs immediately after replacing the C299MAIN board with a new one, transfer the backup parameters from the old C299MAIN board to the new one. Execute “Write D/A Correction Values” in the diagnostic mode.
5. If the printer’s condition is not improved by the above items (adjustments), check the following items using the self-diagnostic function.
n
Head tilt adjustment
n
Head height adjustment

SMUDGED OR MARRED PRINTOUT (FRONT)

If smudging or marring occurs due to rubbing by the head, etc. on the paper’s printed surface, check the following items.
1. If smudging is occurring at the front end of the roll paper or at the rear end, widen the margins at the front end and rear end. (Set the “Roll Paper Margin” front end and rear end on “15 mm”.)
(If high duty printing was done close to the front end and rear end (margin = 3 mm), the paper will contain a large amount of ink and deformation of the paper will be accelerated, and depending on the case, the paper will touch the heads.)
2. If paper with weak edges which cannot move smoothly along the paper path is being used, Select “NORM” for “SUCTION” in the “PAPER CONFIG. MENU”, which is in the “Panel Settings”.
3. If there is rubbing and smudging due to slow drying in printing of user paper.
n
Set the stand basket paper Eject direction on Front.
n
In the item “DRYING TIME” in the User Paper Setting Menu”, in “Panel Settings,” set the drying time (the time until auto paper cutting is carried out after printing is finished (the default is 0 min. The maximum is 30 min.).
4. If the trouble cannot be resolved by the above methods, check the following.
n
The cap assembly / tension spring is off. (If this spring comes off, cap will collect inside the cap and ink that adheres around the head nozzle surface ends up adhering to the paper.
CHECK
PO IN T
If you have performed the “Head tilt adjustment” or “Head height adjustment,” be sure to carry out the “Round trip print position adjustment” and “Gap adjustment.”

EPSON Stylus Pro 7500 Revision c

SMUDGED OR MARRED PRINTOUT (REVERSE SIDE)

If smudging or marring of the paper back surface with ink occurs, the following items should be checked.
1. Check if there isn’t ink adhering to the paper feed path. If there is ink adhering, it should be wiped off.
n
Sub-platen A/B Surface
n
Grid roller surface
n
Paper guide L surface
n
Paper guide L2 surface
2. One likely cause of ink adhering to the above parts is the following cause.
n
Paper feeding at a slant during printing (at the point when 1 page is finished)
CAUTIO N
n If the Paper Skew Detection setting is off in “Printer Settings” ->
“Panel Setting Menu” -> “Paper Width Detection,” if the user’s paper size setting is not correct, the surface of the platen will be printed.

WHITE OR BLACK BANDING

If white or black banding (lines across the page) appear on your printout, try the following.
1. Print the “Nozzle Check Pattern.” If it is normal, carry out the “Head Slant Adjustment.” If skipping of dots occurs, carry out “Cleaning.”
2. If skipping of dots is not the cause, carry out adjustments of the print heads. Head slant adjustment (B head / C head)
n
If each of the nozzle rows on the B head or C head is not positioned so that it is perpendicular to carriage travel direction, overlapping of the raster lines which are printed and compose the print will occur, and this will cause dense portions and white streaks between raster lines.
n
Head height adjustment (B and C heads)
n
Round trip print position adjustment.
n
Gap adjustment.
n
In the self-diagnostic mode, check if the value written for the head ID.

CAUTIO N
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 you move to is safe.
n Because the printer is much heavier than most printers (about
43.5Kg for the printer body/ 52Kg for the printer and stand), you need to take extra care. If you need to take apart the printer and stand or lift the printer, two people are necessary.
n If you remove the ink path system parts and replace them, run
the “Inter-User Transport Mode” and discharge the ink.
n As necessary, after discharging the ink using the above method,
carry out ink initial filling using the “Transport Fluid Cartridges (x 6 cartridges), then discharge the transport fluid in the Inter­User Transport Mode to clean the ink system even more thoroughly.
n After removing any of the ink related parts, double check to
make sure all parts are secured; otherwise you’re going to be in big trouble.
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 ink­related parts.
n When working on the electrical circuit boards, be careful
concerning static electricity which can cause damage to the board. It is recommended you 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 at a 90 degree angle to the connector. Otherwise, internal contact of the leads may be damaged and this can cause a short-circuit.
n When replacing connector wires, be careful to replace the entire
length of the wire exactly as you found it; rubbing against edges or moving parts can cause noise in the wires.
n As necessary, if you remove each cover operate the printer, care
should be taken not to get injured by the operation of the drive system units.
n The cutter blade is extremely sharp, so care should be taken not
to injure yourself when handling it.
n An ultra-hardened blade is used for the cutter blade, and
physically, it is extremely brittle material, so care should be taken not to bump it against any of the metal parts of the printer, etc. and damage it.
n When performing service operations on items which are
controlled as after service parts but which no procedures have been provided for, the state of the parts should be observed closely before beginning the operation to get a thorough idea of how to proceed.
n See the drawing at right concerning directions during repair
operations.
n If you have to loosen a screw that has blue screw-lock applied to
its head, make sure you apply blue screw-lock again when reassembling.
