- The temperature and humidity of the site must be as indicated, and the site must be away from a water faucet, water boiler, humidifier; moreover, the machine

must not be near a fire or subjected to dust.

- The site must be free of ammonium gas.

- The machine must not be subjected to the direct rays of the sun. As necessary, curtains must be furnished.

- Check if the paper is dry. If moist, try paper fresh out of package.

- Check that the amount of paper placed in the cassette and the manual feed tray is as indicated.

- If transparencies are used, check to see if they are placed in the correct orientation.

15.1.3 Checking the Durables

1. Reader Unit

- Check the optical system (contact sensor, white plate, copyboard glass, reading glass) for a scar, dirt, and foreign matter.

- Check the contact sensor unit to see if it moves smoothly. Check its rail for dirt.

- Check the contact sensor for flickering.

- Check the scanner for condensation.

2. Process

- Check the drum unit to see if it is attached properly.

- Check the photosensitive drum for a scar and dirt.

- Check the patch image read sensor window for dirt.

3. Transfer

- Check the secondary transfer outside roller for wear, scar, dirt, and deformation.

- Check the blade of the cleaning unit for a tear, warping, deformation, and stray toner.

4. Fixing

- Check the fixing film/ pressure roller for wear, scar, dirt, and deformation.

- Check the fixing thermistor for an open circuit.

- Check the thermal switch for electrical continuity.

5. Paper Movement

- Check if there is foreign matter such as paper lint.

- Check the pickup/feed/separation roller for a buildup of paper powder, wear, scar, dirt, and deformation.

- Check the registration roller (middle, outside)/paper path roller for wear, scar, dirt, and deformation.

- Check the feed guide for wear, scar, dirt, and deformation.

- Check the paper for a bent leading edge, curling, waving, and moisture.

- As necessary, try transparencies of a type recommended by Canon to see if the problem, if any, is corrected.

6. Machine

- Check if an excess load is imposed on the drive system.

- Check the gears for wear and chipping.

7. Cassette

- Check if the cassettes are fitted properly. Check also to see that the dial is set an appropriate paper size . As necessary, try a normal cassette if the problem, if

any, stops.

- Check the movement of the cassette holding plate is smooth. Check also to see that the holding plate is free of deformation.

- Check if the side guide plate/trailing edge plate inside the cassette are set correctly.

8. Service Mode

- Check that the various CCD adjustment values are as indicated on the service label.

(COPIER>ADJUST>CCD>all items)

- Check if registration adjustment is correct.

(COPIER>ADJUST>FEED-ADJ>REGIST)

- Check if the machine inside temperature/humidity is the correct reading.

(COPIER>DISPLAY>ANALOG>TEMP/ABS-HUM)

- Check the image read position adjustment is correct.

(COPIER>ADJUST>ADJ-XY>ADJ-X/ADJ-Y)
