Scanner Mechanism This mechanism consists of the following: - document tray ASSY which consists of a document chute and document tray, - automatic document feeder (ADF) unit which consists of a document feed roller ASSY, document ejection roller ASSY, ADF motor, and document front and rear sensors, and - scanner unit which consists of a scanner top cover, CCD unit, CCD drive mechanism, CCD HP sensor, and scanner base. For details about the sensors, refer to Section 2.3.
III - 3
This scanner mechanism supports a dual scanning system. (1) If you set documents with their faces up on the document chute and start the scanning operation, the ADF motor rotates so that the document feed roller ASSY feeds those documents into the ADF unit, starting from the top sheet to the bottom, page by page. Each document curves downwards and turns to the right so as to advance above the CCD unit, and then it is fed out to the document tray with the document ejection roller ASSY. This way, documents move above the CCD unit being kept in a stationary position. (2) If you open the scanner unit, put a sheet of document (or put a bound book opened) on the glass of the scanner top cover, close the scanner unit, and start the scanning operation, then the CCD drive mechanism will be driven. That is, the CCD motor rotates and its rotation will be transmitted via the gear train to the CCD drive belt. The CCD unit, which is supported and guided by the CCD rail, is secured to the CCD drive belt. Clockwise and counterclockwise rotations of the CCD motor move the CCD unit to the right and left, respectively. In this scanning system, the CCD unit moves horizontally beneath a document being kept in stationary position. The CCD unit contains a charge coupled device (CCD) image sensor. The cold-cathode fluorescent lamp illuminates a document and the reflected light of the scanned image data is transmitted via the mirrors into the lens which reduces the scanned data so as to form the image on the CCD.

Laser Printing Mechanism
2.2.1
Paper pick-up and registration mechanism
III - 5
At the 1st stage, the controller drives the main motor without energizing the solenoid so that the paper feed roller simply idles. At the 2nd stage, the controller energizes the solenoid so that the paper feed roller no longer rotates and the paper pick-up roller starts rotating to pick up paper into the machine, a sheet at a time. After the leading edge of the pulled-in paper passes through the manual insertion sensor actuator, the paper is further fed for the specified time length. Accordingly, the leading edge will reach the paper feed roller where the paper skew will be eliminated. At the 3rd stage, the controller deenergizes the solenoid to rotate the paper feed roller for feeding paper to the transfer block in the drum unit. When the leading and trailing edges of the paper pass through the registration sensor actuator, the sensor signals them to the controller. According to those signals, the controller may determine the first print position on the paper.
2.2.2
Print process mechanism
III - 6
The print process unit works with laser beam, electrical charges, and toner. The graph below shows the transition of electrical charge on the surface of the laser-sensitive drum through the four processes: charging, exposing, developing, and transferring processes.
III - 7
2.2.3
Heat-fixing mechanism
As the paper passes between the heater roller and the pressure roller in the heat-fixing unit, the heater roller fuses the toner on the paper. The controller monitors the internal resistance of the heater thermistor to keep the surface temperature of the heater roller constant by turning the halogen heater lamp on and off.
III - 8
2.2.4
Paper ejecting mechanism
After the paper passes through the heat-fixing process, it will be ejected from the heat-fixing unit by the paper ejection roller. If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the sensor signals the start of paper ejection. If the trailing edge has passed through the sensor actuator, the sensor signals the completion of paper ejection. The paper will be turned over along the outer chute and ejected onto the main cover by the exit roller.
III - 9

DISASSEMBLY/REASSEMBLY
To prevent the creation of secondary problems by mishandling, observe the following precautions during maintenance work. (1) Unplug the power cord from the power outlet before accessing parts or units inside the machine. When having access to the power supply, be sure to unplug the power cord from the power outlet. (2) When servicing the optical system of the laser printing unit, be careful not to place screwdrivers or other reflective objects in the path of the laser beam. Be sure to take off any personal accessories such as wrist watches and rings before working on the printer. A reflected beam, though invisible, can permanently damage your eyes. (3) If the machine has been printing, allow the heat-fixing unit (inside this unit is a red-colored heater roller) sufficient time to cool down before starting maintenance jobs. It is HOT! (4) Be careful not to lose screws, washers, or other parts removed for parts replacement. (5) Do not remove gears from the document feed roller ASSY or document ejection roller ASSY if at all possible. Once removed, they will become unusable and new gears will have to be put back in. (6) When using soldering irons and other heat-generating tools, take care not to damage the resin parts such as wires, PCBs, and covers. (7) Before handling the PCBs, touch a metal portion of the machine to discharge static electricity; otherwise, the electronic parts may be damaged due to the electricity charged in your body. (8) When transporting PCBs, be sure to wrap them in conductive sheets such as aluminum foil. (9) Be sure to reinsert self-tapping screws correctly, if removed. Unless otherwise specified, tighten screws to the following torque values: Taptite, bind B and cup B Taptite, cup S Other screws M3: M4: M3: M3: M4: 0.7 N·m 0.8 N·m 0.8 N·m 0.7 N·m 0.8 N·m
n Safety Precautions
(10) When connecting or disconnecting cable connectors, hold the connector bodies not the cables. If the connector has a lock, always slide the connector lock to unlock it. (11) Before reassembly, apply the specified lubricant to the specified points. (Refer to Section 2 in this chapter.) (12) After repairs, check not only the repaired portion but also that the connectors and other related portions function properly before operation checks.

A new heat-fixing unit will be provided with the heater thermistor harness being taped to the unit. Before installing the unit, remove the tape. When setting the heat-fixing unit back into place, make sure that the heater wires are routed through the latch of the fan duct (see the illustration given on page IV-41) and then route the long heater wire as shown below.
·
If you remove and reinstall the heat-fixing unit because of any failure, make the machine enter the maintenance mode (see Note) after completion of reassembly and then make it exit from the mode (by pressing the 9 key twice). Otherwise, the heat-fixing unit may not become energized because of the following reason: If the failure of the heat-fixing unit is caused by an opening of the thermistor circuit (that senses the temperature of the heat-fixing unit), the system misinterprets the hot heater as being cold. As a result, the temperature of the heat-fixing unit may become excessively high. To prevent the system from heating the hot heater further at the next powering-on, it is designed so that the heater will not be energized. To cancel this setting, you need to carry out the above maintenance-mode procedure.
(Note) Entry into the maintenance mode Machines w/ fax: Press the Function/Menu, *, 2, 8, 6, and 4 keys. Machines w/o fax: Press the Menu, 0, 2, 8, 6, and 4 keys.
