7.11 Cleaning the Printer 203
If you experience the following problems, clean the part of the printer indicated in the table.
Cleaning Procedure
If you experience vertical patches on your output, clean the interior of the printer as 
instructed below:
1. If paper is loaded in the bypass tray, 
remove the paper and close the bypass 
tray cover.
Important
• When closing the bypass tray cover, be careful not to 
get your fingers caught between (the left or right edge 
of) the cover and the printer.
2. Push up the lever A and open the front 
cover.
3. Press the orange button shown in the figure 
and open the output tray cover.
4. Hold the drum cartridge by the handles with 
both hands, and lift it straight up.
Important
• After removing the drum cartridge, put it in a box or 
aluminium bag, or wrap it with a thick cloth to avoid 
strong light.
• When placing the drum cartridge on a table or on the 
floor, place the side with the handles facing up. Do not 
place the cartridge upright or upside down.
