Automatic Drum Cleaning
Introduction
The imaging drum inside the machine can get contaminated with glue spots. Glue spots on the
drum can affect the print quality. Possible causes of the glue spots:
• The use of recycled media, or
• Wrapper glue residues on one or more sheets of paper.
The machine contains a sensor that can detect glue spots. When the [Automatic drum cleaning]
setting is enabled, and spots are detected, an automatic drum cleaning procedure will take place.
NOTE
When automatic drum cleaning is enabled, the cleaning will not take place before the first
detection of glue spots. If you want to clean the drum immediately, you must start the manual
drum cleaning procedure via the control panel ([System] -> [Maintenance] -> [Go to maintenance
tasks] -> [Clean the drum] -> [Start]).
Precautions
Some contamination of the drum cannot be excluded completely, but you can take precautions to
limit the possibility of contamination.
Advice:
• Open the wrapper very carefully, using a knife or scissors.
• Remove the top and bottom sheets of the paper package before you load the paper into a
paper tray.
• Use paper from a box.
