Power Safety Precautions

Warning

Power Source

Disconnecting Power

For 115 VAC printers, do not apply more than 127 volts RMS between the supply conductors or between either supply conductor and ground. For 230 VAC printers, do not apply more than 254 volts RMS between the supply conductors or between either supply conductor and ground. Use only the specified power cord and connector. This manual assumes that the reader is a qualified service technician.

Plug the three-wire power cord (with grounding prong) into a grounded AC outlet only. If necessary, contact a licensed electrician to install a properly grounded outlet. If the product loses its ground connection, contact with conductive parts may cause an electrical shock. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation.

Turning the power Off using the power switch does not completely deenergize the printer. You must also disconnect the power cord from the printer’s Alternating Current (AC) inlet. Disconnect the power cord by pulling the plug, not the cord.

Disconnect the power cord in the following cases:

■ if the power cord or plug is frayed or otherwise damaged,

■ if any liquid or foreign material is spilled into the product,

■ if the printer is exposed to any excess moisture,

■ if the printer is dropped or damaged,

■ if you suspect that the product needs servicing or repair,

■ whenever you clean the product.

Electrostatic Discharge Precautions

Some semiconductor components, and the respective sub-assemblies that contain them, are vulnerable to damage by Electrostatic Discharge (ESD). These components include Integrated Circuits (ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors, and other semiconductor chip components. The following techniques will reduce the occurrence of component damage caused by static electricity.

Be sure the power is Off to the chassis or circuit board, and observe all other safety precautions.

■ Immediately before handling any semiconductor components assemblies,

drain the electrostatic charge from your body. This can be accomplished by touching an earth ground source or by wearing a wrist strap device connected to an earth ground source. Wearing a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to remove the wrist strap before applying power to the unit under test to avoid potential shock.

■ After removing a static sensitive assembly from its anti-static bag, place it

on a grounded conductive surface. If the anti-static bag is conductive, you may ground the bag and use it as a conductive surface.

■ Do not use freon-propelled chemicals. These can generate electrical

charges sufficient to damage some devices.

■ Do not remove a replacement component or electrical sub-assembly from

its protective package until you are ready to install it.

■ Immediately before removing the protective material from the leads of a

replacement device, touch the protective material to the chassis or circuit assembly into which the device will be installed.

■ Minimize body motions when handling unpacked replacement devices.

Motion such as your clothes brushing together, or lifting a foot from a carpeted floor can generate enough static electricity to damage an electro-statically sensitive device.

■ Handle IC’s and Erasable Programmable Read-Only Memories

(EPROM’s) carefully to avoid bending pins.

■ Pay attention to the direction of parts when mounting or inserting them on

Printed Circuit Boards (PCB’s).

General Information

Two types of diagnostic functions are available:

1. Auto Diagnostics: The printer is checked when whether or not it is turned

On. It is checked whether or not hardware (ROM, RAM, ASIC, etc....)

operates properly.

2. Manual Diagnostics: Only qualified service personnel can perform manual

diagnostics.

The Power Save Mode is controlled by the main system firmware. In order to switch the Ready state to the Power Save Mode after a specified time, the main system sends a sleep command to the engine. When the engine receives a sleep command, it stops the operation of the Fuser and the Fan Unit in the engine. The main system then sets the engine to a sleep state.

User can adjust Power Save Mode for the Phaser 3250 printer. The Power Save can be set from 5 to 120 minutes.

Theory of Operation

Thermistor (Temperature Detecting Sensor)

The Thermistor is used to detect the temperature of the heating unit and feeds this data into the main processor.

Thermostat (Heat Lamp Power Cut-Off)

When the Heat Lamp becomes too hot, the Thermostat cuts off power to the Lamp to prevent from overheating.

Heat Roller

The Heat Roller transfers heat from the Lamp to the paper. As the paper passes between the Heat Roller and Pressure Rollers, the toner is melted and permanently fixed to the paper. The surface of the Heat Roller is coated with Teflon, so that toner does not stick to the surface.

Pressure Roller

The Pressure Roller, mounted under a Heat Roller, is made of a silicon resin and the surface is also coated with Teflon. When paper passes between the Heat Roller and the Pressure Roller, toner powder is melted and permanently fixed to the surface of the paper.

Laser Unit

s3250-015

Theory of Operation

The Laser Unit is the core part of the Phaser 3250 and is controlled by a video controller. The Laser Unit converts video data received from the computer into an electrostatic latent image on the surface of the OPC Drum. This is achieved by controlling the laser beam and exposing the surface of the OPC Drum to the laser light. A rotating polygon mirror reflects the laser light onto the OPC. Each face of the mirror produces one scan line. The OPC Drum rotates at the same as the paper feeding speed. As the OPC Drum turns, the laser scans, which creates the full page image.

The Horizontal Sync (HSYNC) signal is created when the laser beam from the Laser Unit reaches the end of the polygon mirror and this signal is sent to the controller. The controller detects the HSYNC signal to adjust the vertical line of the image on paper. In other words, after the HYSNC signal is detected, the image data is sent to the Laser Unit to adjust the left margin on the paper.

Theory of Operation

Exit Sensor Actuator

s3250-018

Sensor Input Circuit

Paper Empty Sensing

The Paper Empty Sensor (Photo Interrupter) on the High-Voltage Power Supply (HVPS) provides the state of paper to the CPU whether the tray is empty or not when the Actuator is in operation. When the tray is empty, the Paper Empty Sensor detects E20 of the CPU and then flashes the red LED on the printer’s Control Panel.

Paper Feeding with Print Cartridge Sensing

When paper passes the Actuator on the Feed Sensor, it detects the signal of the Photo Interrupter, sends the paper feeding state to the CPU, and starts creating the image after a specified delay time.

If the Feed Sensor is not detected within one second after paper is fed, a paper Jam0 occurs, while the amber LED is lit on the printer’s Control Panel.

After the Print Cartridge is installed, the sub CRUM reads the data of the Print Cartridge from contacting with the CRUM involved in the Print Cartridge. If the data of the Print Cartridge is invalid, the red LED is lit on the printer’s Control Panel.

Paper Exit Sensing

This detects that paper exits cleanly from the printer using an Exit Sensor on the HVPS and Actuator on the printer frame. Paper detects the On/Off time of the Exit Sensor by reading D22 of the CPU, and the normal operation or a jam status is reported. If a Jam2 error occurs, the amber LED is lit on the printer’s Control Panel.

2-16 Phaser 3250 Laser Printer Service Manual

Theory of Operation

Front Cover Open Sensing

The Front Cover Sensor is located on the HVPS. When the Front Cover is open, +24 V that is supplied to the DC Fan, Solenoid, Main Motor, Polygon Motor in the Laser Unit, HVPS, and Laser Diode are cut off. When the Front Cover is open, the red LED is lit on the printer’s Control Panel.

DC Fan/Solenoid Driving

It is driven by transistor and controlled by the Main Fan (D14), Duplex Fan (E16), Pick-Up Clutch (C23), Regi Clutch (C18), and the Manual Feeder Clutch (D15) of the CPU.

When it is high, the Transistor turns On and drives the Fan, and it is Off when Sleep mode is selected. There are three Solenoids, and they are driven by paper Pick-Up, Regi, and Manual Feeder signals. It is turned On or Off by C23, C18, and D15 of the CPU.

The diode protects the driving Transistor from the noise pulse, which is created when the Solenoid is de-energizing.

The Fan Driving Circuit is driven by the Transistor and controls D14 and E16 of the CPU.

Motor Driving Circuit

The main motor driving circuits are located on the Brush-less Direct Current (BLDC) Motor Assembly. The Motor Assembly Control Board contains a Motor Driver IC.

The Exit Motor Driving Circuit is formed when the driver IC is selected. The AN44060A Motor Driver IC is used in this case. The resistance Rs value for sensing and voltage value for the V reference can be changed by motor driving voltage value. The motor driving voltage is calculated with the following formula:

IN 0, 2 IN 1, 3 Output Current

L L Vref / (10*Rs) = lout H L Vref / (15*Rs) = lout * 2/3 L H Vref / (30*Rs) = lout *1/3 H H 0

The motor driving circuit is formed when the driver IC is selected. The A3977 Motor Driver IC is used in this case. The resistance Rs value for sensing and voltage value for the V reference can be changed by the motor driving voltage value.

■ I = Vref / Rs, wherein Vref is (R1 x 5V) / (R1+R2)

Fuser AC Power Control

The Fuser receives heat from AC power, which controls the switch with the Triac, a semiconductor switch. The On/Off control is operated when the gate of the Triac is turned On/Off by Phototriac (insulting part). In other words, the AC control part is passive circuit, so it turns the heater On/Off while retrieving signal from the engine control part.

When the Heater On signal is turned On at the print engine, the LED of PC501 (Photo Triac) measures the voltage and flashes. From the flashing light, the Triac part (light receiving part) measures the voltage, and the voltage is supplied to the gate of Triac and flows into the Triac. As the result, the AC current flows in the Lamp, and heat is generated.

On the other hand, when the signal is Off, the PC501 is Off, the Triac is cut off at the gate of Triac. When the Triac turns Off, the Lamp is turned Off.

Feeding

When feeding from a paper tray, the drive of the Pick-Up Roller is controlled by the Solenoid.

The printer feeds the paper from the Manual Feeder according to information provided by the Manual Feed Sensor, and by driving the Main Motor, insert the paper in front of the Feed Sensor.

Different types of Jam are provided in the following table:

Jam Errors

Item Description

JAM 0 This is an indication that the leading edge of the paper did not

pass the Feed Sensor.

■ After paper pick, paper does not enter the printer.

■ After paper pick, paper enters the printer, but does not reach

the Feed Sensor in the specified time.

■ If paper has been picked, and the Feed Sensor is not On, the

printer will re-pick. If after re-picking, the Feed Sensor is still

not reported as On, this error will occur. This is an indication that the leading edge of the paper already passed the Feed Sensor.

■ Even though paper reaches the Feed Sensor, the Feed Sensor

is not On.

JAM 1 This is an indication that the paper is between the Feed Sensor

and the Exit Sensor.

■ After the leading edge of the paper passes the Feed Sensor,

the trailing edge of the paper cannot pass the Feed Sensor in the specified time. (The Feed Sensor cannot be Off.)

■ After the leading edge of the paper passes the Feed Sensor,

paper cannot reach the Exit Sensor in the specified time. (The

Exit Sensor cannot be Off.)

JAM 2 After the trailing edge of the paper passes the Feed Sensor,

paper cannot pass the Exit Sensor in the specified time.

DUPLEX JAM 1 After the trailing edge of the paper passes the Exit Sensor, the

leading edge of the paper cannot reach the Regi Sensor in the specified time.

Driver

Fusing

Theory of Operation

The Main Motor drives the Feed Roller, Developing Roller, and Exit Roller. The BLDC Motor controls acceleration and steadiness of the Rollers. The BLDC Motor is operated by the BLDC Clock and enable signal.

The charging voltage, developing voltage, and transfer voltage are controlled by Pulse Width Modulation (PWM). Each output voltage is changeable due to the PWM duty cycle. The transfer voltage is used when the paper passes the Transfer Roller is decided by environmental recognition. The resistance value of the Transfer Roller changes due to the surrounding environment or the printer, or the voltage value. This change in resistance in turn changes the value of the voltage due to loading. This voltage is fed back into the printer through the A/D Converter. Based on the value fed back, the PWM cycle is changed to maintain the required transfer voltage.

The temperature change of the Heat Roller’s surface is detected according to the value of the Thermistor. The Thermistor resistance is measured using the A/D Converter and thus the CPU can determine the temperature of the Heat Roller. AC power is controlled by comparing the target temperature to the value from the Thermistor. If the value from the Thermistor is out of the controlled range while controlling the fusing process, an error is reported.

■ Lower than -20° C for more than 10

seconds.

Printing

■ Lower than -20° C for more than 10

seconds.

Warm-Up End

■ Lower than -10° C for more than 10

seconds.

Over Heat Error For overall engine state, if the temperature

of the fixing unit is higher than the specified temperature and the temperature state is kept during a specified time. When the error occurs, the engine stops all functions and keeps it at error state.

■ It has been higher than 220° C for more

than 20 seconds.

■ It has been higher than 230° C for more

than 3 seconds.

■ It has been higher than 10° C for more

than 180 seconds.

All LEDs blinking.

Recovering from Heat Error

Heat error is automatically recovered when the error is only caused by Low Heat Error, and not the Heat Errors in Warm-Up state and the Over Heat Error.

When an error occurs, the engine memorizes the present temperature. In case of Low Heat Error, the maximum heat is supplied to the fixing unit.

When a specified time is elapsed, the engine detects the temperature again. If the present temperature is higher than the memorized temperature, the error is recovered.

In case of Over Heat Error, no heat is supplied to the fixing unit. When a specified time is elapsed, the engine detects a present temperature again. If the present temperature is a specified degree lower than the memorized temperature, the error is recovered.

Laser Scanner Unit

The Laser Scanner Unit (LSU) receives image data from the PVC or HPVC and make latent image on the OPC surface. The LSU uses dual beam system, LD1 and LD2. The control method of the two beams are the same. In comparison with a single beam system, dual beam contains half of the LSU’s frequency.

The LSU consists of laser diode (LD) and the polygon motor control. When the printing signal occurs, the laser diode is turned On and the polygon motor is enabled. When the light sensor detects the beam, H-SYNC occurs. When the polygon motor speed becomes steady, Ready mode occurs. If these two conditions are satisfied, the Laser Unit is ready. If the two conditions are not satisfied, one of the two errors are reported as shown in the table below:

Error Description

Theory of Operation

Polygon Motor Error (LReady)

■ When the polygon motor speed is not steady.

■ When printing is started, the engine drives the Polygon

Motor of the LSU. After a specified time is elapsed, if the motor is not at a Ready status, the engine detects the error that the Polygon Motor is not Ready.

H-SYNC Error ■ The Polygon Motor speed is steady, but the H-SYNC is

not generated.

■ When the Polygon Motor is Ready, the LSU sends out

the signal called H-SYNC and used to synchronize with each image line. If the engine does not detect the signal consecutively for a fixed time, H-SYNC error occurs. When this error occurs, the engine stops all functions and keeps it at error state. Red error LED is lit when error occurs.

LSU Error Recovery

When LReady or H-SYNC error occurs, paper exits from the printer. The engine mode is changed to recovery mode and the engine checks the LSU error. When the error stops, print job will continue.
