Chapter 1414-114.1 Making Initial Checks14.1.1 Installation Environment 0013-4591imagePRESS C1 P / imagePRESS C1- Be sure to check that the value of power supply voltage is maintained -/+10% of the specified voltage (do not disconnect the plug even during the nighttime).- Be sure to avoid areas that are: high temperature/humidity (around water tap, water heater, and humidifying device), cool temperature, near the fire, or dusty.- Be sure to avoid areas subject to evaporation of ammonia gas.- Be sure to avoid areas subject to exposure to direct sunlight. Instruct to attach curtains if there is no choice.- Be sure to check the machine is installed in a place subject to sufficient ventilation, and also the machine can maintain its level.- Be sure to check that the machine's power plug is connected to the outlet.14.1.2 Checking of Paper 0013-4592imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+- Check if Canon-recommended paper is used.- Check if the paper is moistened. Try to make prints by setting paper taken out from a new package.14.1.3 Checking of Paper Setting 0013-4593imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+- Check if the specified volume of paper is set properly in the cassette and the manual feeder tray.- In case that the transparency is used, check if the transparency is set with the correct orientation in manual feeder tray.14.1.4 Checking of the Durable Parts 0013-4595imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+Check the list of expected life of durable parts, and replace parts that reach the stated life.14.1.5 Checking of the Periodically Replaced Parts 0013-4597imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+According to the list for periodically service/the table of periodically replaced parts, replace parts that reach the stated life counts.14.1.6 Checking of Each Unit/Checking Item of Each Function System 0013-4598imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+1. Reader- Check if there is no scar, soil or foreign particle in the scanning system (mirror/ white plate/ copyboard glass/ reflector).- Check if the mirror mount moves smoothly/there is no soil on the rail.- Check if there is no flickering of scanning lamp.- Check if the scanning system wire is set properly.- Check if there is no condensation in the scanning system.2. Process- Check if there is toner in the toner container.- Check if the drum unit is reliably attached.- Check if there is no scar or soil on the photosensitive drum.- Check if the window of the patch image read sensor is not soiled.3. Transfer- Check if there is no foreign particle on the secondary transfer unit.- Check if there is no wear, scar, soil and deformation on the ITB/secondary transfer roller.- Check if there is no break, flip, and deformation of the blade or spray of toner of the ITB cleaning unit.4. Fixing- Check if there is no wear, scar, soil and deformation of the fixing belt/pressure roller.- Check if the fixing heater (main/sub) activates after turning on the power.- Check if the fixing thermistor is not open circuit.- Check if the thermal switch is conductive.5. Paper Feeding- Check if no foreign particle (such as scrap of paper) is remained.- Check if there is no paper lint accumulating on the pickup/feed/separation roller. Also if there is no wear, scar, soil or deformation of the pickup/feed/separationroller.- Check if there is no wear, scar, soil and deformation of pre-registration roller/registration roller (upper/lower)/ paper path roller.- Check if there is no wear, scar, soil or deformation of the feeder guide.- Check if there is any fault of fold-down of leading edge/curl/ruffling/moisture absorption of paper.- Check if the performance improves when using Canon-recommended paper/transparency.6. Machine- Check if the load of the drive system is not heavy.- Check if there is no wear or chip of the gear.7. Cassette- Check if: the cassette is attached properly; the paper size is set correctly; the same symptom does not occur when replacing the cassette that performs normaloperation.- Check if: the move of the cassette middle plate is smooth; there is no deformation.- Check if the side guide plate/rear guide plate of the cassette is attached properly.- Check if the switch of the cassette heater is ON (in case the cassette heater is attached).
