a. There must be a source of power whose voltage is as specified (+/-10%). The power plug must never be disconnected day and night.
b. The machine must not be in an area subject to high humidity (near a water faucet, water boiler, humidifier). The site must not be too cold or subject to dust. The
machine must not be near a source of fire.
c. The site must not be subject to ammonium gas.
d. The machine must not be exposed to the rays of the sun. As necessary, curtains must be provided.
e. The area must be well ventilated. The machine must be on a level floor.
f. Be sure that there is a source of power that can be used by the machine.

a. Be sure the paper being used is of a type recommended by Canon.
b. Be sure that the paper is not moist. Try using paper fresh out of package.
13.1.3 Checking the Placement of Paper
/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /
a. There must be paper in the cassette or the tray deposited within a specific limit.
b. If transparencies are used, be sure that they are placed in the manual feed tray in the correct orientation.
13.1.4 Checking the Durables
/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /
Refer to the table of durables, and replace those that have reached the end of their lives.

<Reader>
- Check whether the optical system (contact sensor/white panel/copyboard glass) is free from scratches, stain, foreign objects.
- Check whether the contact sensor unit moves smoothly. Check whether the rails are free from dirt.
- Check whether the contact sensor is not flickering.
- Check whether the optical system is free from dew condensation.
<Process>
- Check whether the toner cartridge is installed securely.
- Check whether the photoconductor drum is free from scratches and stain.
<Transfer>
- Check whether the transfer roller is free from scratches, stain, and deformation.
<Fixing>
- Check whether the fixing film and pressure roller are free from wear, scratches, dirt, and deformation.
- Check whether the fixing thermistor is broken.
- Check whether the temperature huse is conductive.
<Paper transport >
- Check whether the paper transport path is free from foreign objects such as paper chips.
- Check whether the paper pickup, feed, and separation rollers are free from paper dust. Also check whether these rollers are free from wear, scratches, dirt, and
deformation.
- Check whether the registration roller and paper path are free from wear, scratches, dirt, and deformation.
- Check whether the transport guide is free from wear, scratches, dirt, and deformation.
- Check whether the leading edge of paper is not folded, curled, wavy, or damp.
- Check whether use of the Canon-recommended paper/transparency solves the problem.
<Machine>
- Check whether the drive system load is heavy.
- Check whether gears are worn or cracked?
<Cassette>
- Check whether the cassette is installed properly. Check whether the paper size is set properly. Check whether the same symptom occurs when the cassette is
replaced with the cassette verified to be normal.
- Check whether the middle plate of the cassette moves smoothly. Check whether it is deformed.
- Check whether the side and rear alignment plates are adjusted properly.
- Check whether the cassette heater switch is turned on (when a cassette heater is installed).
<Service Mode>
- Check whether various adjustment values are the same as those printed on the service label.
- Check whether the output between CIS channels has been corrected.
(Service mode>TEST MODE>"2"(SCANTEST)>"1")
- Check whether the read position has been adjusted properly. (Stream reading: Only when the ADF is installed)
(Service mode>TEST MODE>"2"(SCANTEST)>"3"(SHEET POS ADJ))
<General>
- Check whether the power cord is plugged in the outlet securely.
- Check whether the specified AC voltage is applied to the outlet.
- Check whether sensors, clutches, motors, and solenoids are operating normally. Check whether connectors are connected properly.
(Check the power supply and signal routes with reference to the general circuit diagram.)
- Check whether all cables are routed properly and all screws are not loose.
- Check whether all outer covers are attached.
- Check whether the main power switch and the power switch on the operation pane are turned on.
- Check the power cables and signal cables of options are connected properly.
