Chapter 1515-115.1 Making lnitial Checks15.1.1 Checking the Site Environment 0014-3011Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iR C2550- The voltage of the source of power must be as indicated (+/-10%).- 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 machinemust 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.- The site must be well ventilated, and its floor must keep the machine level.- The machine must remain connected to the wall outlet at all times.15.1.2 Checking the Paper 0014-3012Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iR C2550- 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 0014-3014Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iR C2550- Check the Durables Table, and replace those parts that have reached the end of the indicated lifetimes.15.1.4 Checking the Units and Functional Blocks 0014-3017Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iR C25501. 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, ifany, 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)- Check if the value for ADJUST/OPTION is as indicated on the service label.- Check if error initialization has been executed.(COPIER>FUNCTION>CLEAR>ERR)9. General- Check the power plug is connected properly.- Check there is the rated AC voltage at the power outlet.- Check the sensors, clutches, motors, and solenoids operate normally. Check the connectors for poor contact.(Be sure to check with the General Timing Chart for reference to power/signal routes.)- Check the leakage breaker/circuit breaker operates normally.
