After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.
Use only a grounded tip soldering iron to solder or desolder ESDs. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conductive material.
Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.
Minimize bodily motions when handling unpackaged replacement ESDs.

Toner Cartridge. Paper Tray Tray1. Signals from these sensors are passed. This part connects the set with the PSTN. The Toner process is a single part diamagnetic process. The scanner is designed around a dpi CIS module. The CIS scanning width is maximum mm, effective width is mm.. It also manages the transfer of that image onto paper and the fusing of the image. These are integrated into a singe PBA. This unit. The Toner Cartridge consists of integrated Exposure and Developer units.
This is the core of the laser printer. It converts the 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 and each side of the mirror is one scan line.
The OPC drum turns as the paper feeds to scan the image down the page. The transfer roller transfers toner from the OPC drum to the paper. This consists of a heat lamp, heat roller, pressure roller, thermistor and thermostat. By use of heat and pressure toner is caused to melt and adhere to the paper surface in order to complete the printing process. There is a universal cassette which automatically loads paper and the manual feed which supplies paper single sheet at a time.
The cassette has a friction pad which separates paper to ensure single sheet feeding, and it has a sensor, which checks when the paper tray is empty.
The transfer roller transfers toner from the OPC drum surface to the paper. The motor supplies power to the paper feed unit, the fuser unit, and the toner cartridge. It fixes toner to the paper using pressure and heat to complete the printing job.
The thermostat is a temperature sensing device, which cuts off the power to the heat lamp to prevent overheating fire when the heat lamp or heat roller overheats. The Thermistor detects the surface temperature of the heat roller, this information is sent to the main processor which uses this information to regulate the temperature of the heat roller.
The surface of the Heat Roller is heated by the Heat Lamp. As the paper passes between the Heat and Pressure rollers the toner is melted and fixed permanently to the paper.
The surface of the roller is coated with Teflon. This ensures that toner does not adhere to the roller surface. The Pressure Roller mounted under the heat roller, it is made of a silicon resin, and the surface of the roller is coated with Teflon. Minimum Scan Line Time : 1.
Scan Resolution : Color : Max. Scan Width : mm. The toner cartridge is an integral unit containing the OPC unit and toner unit. The OPC unit consists of the OPC drum and charging roller, and the toner cartridge unit consists of the toner, supply roller, developing roller, and blade Doctor blade. This consists of the CPU, printer scanner and line control functions. Circuits on the PBA drive include the main motor paper feed, cartridge, fuser , clutch driver, pre-transfer lamp driver, heat-lamp driver, CIS driver, scan motor driver, modem and fan driver.
The signals from the paper feed jam sensor and paper empty sensor are inputted to the main board from the power supply PBA.. It is controlled by the system program held in flash memory. This stores the system program. Firmware upgrade is achieved by downloading from the new image using the PC Interface. This is used as a buffer, system working memory area, etc. This memory is also used to store faxes waiting to be sent or waiting to be printed.
When the cassette is empty the printer displays a message on the LCD panel. When paper passes the actuator on the feed sensor, it is detected by the Photo interrupter. Displayed on the LCD panel. When a toner cartridge is inserted it also operates the Paper Feed sensor. A message is displayed on the LCD if no cartridge is detected.
This detects that paper exits cleanly from the Machine using an exit sensor on the engine board and actuator on the frame. The Cover open sensor actuator is located on the front cover and the senor is in the main frame.
When it is high the fan is activated by turning on the TR, and it is off when the sleep mode is selected. There are two solenoids and these are driven by the Paper Pick-up and MP signals. The drive time is ms. The motor driving circuit is activated when the Driver IC is enabled.
An A Motor driver IC is used in this case. The resistance Rs value of sensing and the voltage value of the V reference can be changed by the motor driving voltage value. The CPU is used to modify some of these voltage settings to provide the ideal voltages to create the image.
F V L2A. It is possible that waste toner over-flow can occur if this condition persists. Ghost images may appear which repeat at 76mm intervals. A black page is printed out when this happens. Therefore toner with - polarity is developed onto an exposed.
This is the power source for the whole system. It is an independent module so that it is possible to use it for common use. It is mounted at the bottom of the set. It consists of the SMPS section, which supplies the DC power to drive the system, and the AC heater control part, which supplies the power to the fuser.
There are three kinds of power, V exclusive America , V exclusive Europe , and V for China nations with unstable power supply. In the other words the AC control part is a passive circuit. On the other hand, when the signal is off, PC1 is off, the voltage is cut off at the gate of Triac THY1, this Triac is therefore off, and thus the heat lamp is turned off.
If feeding from the cassette the drive of the pickup roller is controlled by controlling the pick-up solenoid. If feeding from the manual feeder the set decides to feed the paper according to the operation of the manual sensor, and by driving the main motor, insert the paper in front of the feed sensor.
When paper moves the occurrence of a paper jam is judged as below. After retrying if the feed sensor is still not on after certain time, it is Jam 0. During this time the feed sensor cannot be Off. The exit sensor cannot be On during this time.
The main motor drives the paper feed, developing unit and the Fuser It is driven by software which controls the acceleration, constant speed and deceleration profiles. Each output voltage is changeable according to the PWM duty cycle.
The transfer voltage used when the paper passes the transfer roller is decided by environment recognition. The resistance value of the transfer roller changes due to the surrounding environment in the room or within the set, this change in resistance in turn changes the value of the voltage due to loading. Based on this fed back value the PWM cycle is changed to maintain the required transfer voltage.
The temperature of the heat roller's surface is detected according to the resistance value of the thermistor. The 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 controlling range while controlling the fusing process, the error stated in the table occurs.
For the domestic model, the Q-PID method has been applied. When the printing signal occurs, the LD is turned on and the polygon motor is enabled. When the light sensor detects the beam, Hsync occurs. When the polygon motor speed becomes a normal, LReady occurs. If these two conditions are satisfied, the status bit of the LSU controller register becomes 1 ant the LSU is judged to be ready.
If the two conditions are not satisfied, the error shown in the table below occurs. The LIU board is the Line interface unit, it is a circuit for interfacing a telephone line with a modem. The circuit consists of a matching transfer to conform to the impedance of the receiving telephone line and a circuit to conform to the impedance of a modem.
Also, there is a ring detect circuit to detect a ring signal from the switchboard and a surge absorber to protect against lighting strike surges on the incoming line. When you disassemble and reassemble components, you must use extreme caution. Please check your email for further instructions.
