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.

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.

Open the feeder cover.

Clean the rollers (a total of three places) inside the feeder cover with a water-moistened cloth. Then, wipe the area with a soft, dry cloth.

Spin the rollers with your hand while cleaning them.

While using the feed dial to turn the resin roller, wipe the resin roller and its surroundings with a water-moistened cloth. Then, wipe the area with a soft, dry cloth.

NOTE
If the feed dial cannot be reached while the feeder is opened, close the feeder → turn the feed dial slightly → open the feeder → clean the roller. Repeat these steps until the roller surface is completely clean.

Automatic Feeder Cleaning

If the originals fed through the feeder have black streaks or appear dirty, clean the feeder rollers by repeatedly feeding blank sheets of paper through the feeder.
