13.3 Operation
13.3.1 1st transfer output control
• The 1st image transfer roller is not equipped with a pressure/retraction mechanism and
presses the transfer belt up against the photo conductor drum.
• The 1st transfer voltage is determined during the image stabilization control in consider-
ation of the machine condition, environment, and print mode.
13.3.2 Transfer belt cleaning mechanism
• To scrape residual toner off the surface of the transfer belt, there is a cleaning blade pro-
vided.
• The cleaning blade is pressed up against the transfer belt, thereby scraping residual
toner off the surface of the transfer belt.
• The toner collecting screw conveys toner scraped off by the cleaning blade into the imag-
ing cartridge.
• The prevention seal is affixed to prevent waste toner from leaking through a gap above
the cleaning blade.
