Cleaning/toner recycle section

A. Removing/reinstalling the cleaning section
NOTE
• Be sure to avoid touching the edge of the cleaning blade with bare hands.
• Before reinstalling the cleaning section, be sure to clean the cleaning section with a blower brush
and a cleaning pad.
• When reinstalling the cleaning section, be sure to apply setting powder to the entire periphery of
the drum and the cleaning blade regardless of these parts being new or used ones.
• When the drum is applied with setting powder, be sure conduct the following operations before
installing the photo conductor section to the main body:
1) To obtain an accurate toner density, clean setting powder splashed onto the gamma sensor
and the maximum density sensor on the toner control sensor board (TCSB) with a cleaning pad
soaked in drum cleaner.
2) With the charger unit and the developing unit removed, rotate the drum one full turn (for splash
prevention of setting powder to the charger and prevention against the image getting blurred).
