2.1 Scanner Mechanism

2.1.1 Document feeding and ejecting mechanism

This mechanism consists of the document st acker, automatic docum ent feeder (ADF), docum ent ejection roller ASSY, and document sensors. (For details about the sensors, refer to Section 2.3.)

If the operator sets documents on the document stacker and starts the scanning operation, the scanner motor rotates so that the ADF (which consists of the separation roller and ADF parts) feeds those documents into the equipment, starting from the bottom sheet to the top, page by page. Each document advances with the docum ent feed r oller ASSY to the scanner, and then it is fed out of the equipment with the document ejection roller ASSY.

2.1.2 Scanner

The scanner uses a contact image sensor (CIS) unit which consists of an LED array illuminating documents, a self-focus lens array collecting the reflected light, a CIS PCB carrying out photoelectric conversion to output picture elem ent data, and a cover glass on which a docum ent advances. W hen the document passes between the document pres s ure bar and the cover glass , it is scanned.

2.2 Laser Printing Mechanism

2.2.1 Paper pulling-in, registration, feeding, and ejecting mechanism

III - 5

Paper pulling-in and registration mechanism

The paper pulling-in and registration m echanism consists of the pull-in roller gear (incorporated in the multi-purpose sheet feeder ), planetary gear system, paper f eed solenoid, s olenoid lever, clutc h release lever, and registration sensor. (For the details about the sensor, refer to Section 2.3.)

If the main motor rotates clockwise, the rotation is transmitted to the intermediate gear of the planetary gear system. As the intermediate gear rotates, the pull-in roller drive gear also rotates since the clutch gear is locked by the solenoid lever and the clutch release lever. Ac cordingly, the pull-in roller in the multi-purpose s heet feeder rotates to pull in paper into the equipm ent, a s heet at a time.

If the paper feed solenoid is retracted and the clutch release lever is operated according to the cam profile of the pull-in roller gear so as to release the c lutch gear, the clutch gear rotates and the pullin roller drive gear does not rotate. In this way, the clutch gear switches the transmission of the motor rotation to the pull-in roller drive gear on and off.

The solenoid on/off timing and the clutch release lever timing allow this mechanism to pull in a sheet and register it against the registration roller.

Paper feeding and ejecting mechanism If the main motor rotates clock wise, the rotation is transmitted via the gear train to the drum drive

gear, heater roller drive gear, and paper ejection roller drive gear. After the paper passes through the heat-fixing process, it will be ejected onto the paper tray. If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the

photosensor becomes opened, signaling the s tart of paper ejec tion. If the trailing edge has passe d through the sensor actuator, the sensor becomes closed, signaling the completion of paper ejection. Then, the main motor stops rotation.

2.2.2 Print process mechanism

The print process unit works with laser beam, electrical charges, and toner. The graph below shows the transition of electrical char ge on the surface of the las er-sensitive dr um thr ough the five processes: charging, exposing, developing, transferring, and erasing processes.

III - 7

2.2.3 Heat-fixing mechanism

As the paper passes between the heater roller and the press ure roller in the heat-fixing unit, the heater roller fuses the toner on the paper.

• Document front sensor which detects the presence of documents.

• Document rear sensor which detects the leading and trailing edges of pages to tell the control circuitry when the leading edge of a new page has reached the starting position and when the scan for that page is over.

• Top cover sensor which detects whether the top cover is closed.

• Registration sensor which detects the leading and trailing edges of paper, which allows the controller to determine the registration timing and check paper jam.

• Paper ejection sensor which detects whether the recording paper goes out of the equipment.

• Toner sensor which detects whether there is toner or a toner cartridge is loaded.

• Toner thermister which detects the ambient temperature of the toner cartridge.

• Heater thermister which detects the temperature of the heater roller of the fixing unit.

• Hook switch* which detects whether the handset is placed on the handset mount.

These photosensors are a photointerr upter consisting of a light-em itting diode and a light-sensitive transistor. Each of them has an actuator separately arranged as shown on the next page.

 Safety Precautions

To prevent the creation of secondar y problems by mishandling, observe the following precautions during maintenance work.

(1) Unplug the power cord from the power outlet before replacing parts or units. W hen having

access to the power supply, be sure to unplug the power cord from the power outlet.

(2) W hen ser vic ing the optical s ystem of the las er pr inting unit, be c areful not to place s cr ewdrivers

or other reflective objects in the path of the laser beam. Be sure to take off any personal accessories such as wris t watches and rings before working on the pr inter. A reflected beam, though invisible, can permanently damage your eyes.

(3) If the equipment has been printing, allow the heat-fixing unit suff icient time to c ool 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 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-gener ating tools, tak e c are not to damage the resin

parts such as wires, PCBs, and covers.

(7) Before handling the PCBs, touch a m etal por tion of the equipment to discharge static electric ity;

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. (10) Tighten screws to the torque values listed on the next page. (11) 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.

(12) Before reassembly, apply the specified lubricant to the specified points. (Refer to Section 2 in

this chapter.)

(13) After repairs, check not only the repaired portion but also that the connectors and other related

portions function properly before operation checks.
