(Be sure to check the power supply and signal routes by referring to the general circuitdiagram.)- Check to see that the leakage breaker and circuit breaker are operating normally.- Check to see that there is no biting of wires and loosening of screws.- Check to see that all external panels and covers have been correctly fitted.- Check to see that the main power switch and the control panel power switch are turned on.- Check to see that the power and signal cables are correctly routed.- Check to see that the operation of the cover switch is normal.- Check to see that none of the fuses on the PCBs have an open circuit.- Check to see that the user has a correct understanding of how to use the machine and is using it correctly.14.1.7 Others 0007-9389iR2270 / iR2870 / iR3570 / iR4570If a machine is brought from a cold to warm room, its inside can start to develop condensation, leading to variousproblems.a. condensation on the BD sensor is likely to cause problems associated with E100b. condensation on the dust-proof glass is likely to cause poor image density in sub scanning directionc. condensation on the contact sensor of the reader unit or on the copyboard glass can cause light imagesd. condensation on the pickup or feed guide can cause paper feed problemsIf the problem given in d. above has occurred, dry wipe the units in the feed system. Do not open the packagecontaining a toner cartridge, developing unit, or drum unit right after it has been brought in from a cold to warm placeto avoid condensation. Be sure to leave it alone for a while (1 to 2 hr), opening it after it has become fully used to thetemperature of the site.
