Routine Cleaning

If the original is not copied clearly, clean the following parts of the machine:
Platen glass
Underside of the feeder/platen cover
Feeder scanning area and rollers
For high-quality printouts, we recommend that you clean these parts regularly.
When cleaning the machine, first turn OFF the main power switch, then disconnect the power cord. Failure to observe these steps may result in a fire or electrical shock.
Do not use alcohol, benzine, paint thinner, or other solvents for cleaning. Doing so may damage the plastic parts.
Disconnect the power cord from the power outlet regularly, and clean the area around the base of the power plug’s metal pins and the power outlet with a dry cloth to ensure that all dust and grime is removed. If the power cord is connected for a long period of time in a damp, dusty, or smoky location, dust can build up around the power plug and become damp. This may cause a short circuit and result in a fire.
IMPORTANT
Do not dampen the cloth too much, as excess water may damage the machine.
Turning the main power OFF will erase all jobs in the machine’s memory.

Platen Glass and Cover

Clean the platen glass and the underside of the feeder/platen cover as described below.
IMPORTANT
If the platen glass or the underside of the feeder/platen cover is dirty, the original may not be scanned clearly, or the size of the original may be incorrectly detected.
1
Clean the platen glass and the underside of the feeder/platen cover with a water-moistened cloth, and then wipe them clean with a soft, dry cloth.
IMPORTANT
Do not dampen the cloth too much, as excess water may damage the machine.

Feeder Scanning Area and Rollers

Clean the feeder scanning area and rollers regularly as described below. If streaks appear on originals fed through the feeder, or if smudges appear on printouts, or if a paper jam occurs frequently, then perform feeder cleaning.
IMPORTANT
Do not dampen the cloth too much, as excess water may damage the machine.
NOTE
The Feeder (DADF-AB1) is optional for the imageRUNNER 2525/2520.
