Cleaning the Inside of the Equipment

When the inside of the equipment needs to be cleaned, the message “Time for cleaning. Open the front cover and 
follow the guidance.” is displayed. In this case, clean the inside of the equipment following the guidance displayed on 
the touch panel. (Depending on the model, this message may not be displayed.)
In addition to this, even if this message is not displayed, perform cleaning when the copied images are uneven and/or 
have white or color streaks in the horizontal direction.

The Main Chargers and LED Print Heads (e-STUDIO2020AC/2520AC)

1

Open the front cover of the equipment.

2

Pull out the cleaner until the mark appears and return it. Repeat this 3 times for each of the 4 
colors.

The cleaner cannot be removed by design. Pulling it out forcibly may cause malfunction.

When only the main chargers need to be cleaned, steps 3 to 12 are unnecessary. Proceed to step 13.

3

Put your fingers in the waste toner box front grooves and take it out toward you pushing down 
the top latch.
