* d. Drum cleaning blade
Since the edge of the blade is vulnerable and can be easily damaged by factors such as the
adherence of paper dust. Replace the cleaning blade with new ones if poor images are printed
due to the damaged blade regardless of the number of output pages if which have been made.

The paper jam may be caused if the tip of the separation finger is damaged or deformed. If there
is any problem with it, replace the finger with a new one regardless of the number of output

finger.
Notes:
• Wipe the tip of the finger lightly with a dry cloth trying not to deform it.
