* h1.
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.
* h2.
Separation fingers for drum
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 pages which have been made.
If any mark which was made by the finger appears on the printed image, clean the tip of
the finger.
* h3.
Recovery blade
Replace the recovery blade regardless the number of output pages if the edge of the blade
get damaged.
Notes:
1. Wipe the tip of the finger lightly with a dry cloth trying not to deform it.
Do not leave the lint on the tip.
2. Apply patting powder to the tip of the fingers and drum surface after replacing or cleaning
them to reduce the load on the drum surface by the finger.
