2.4.6 Fusing
When a sheet of paper leaves the transfer area, static electricity holds
the unfused toner ima
g
e to the surface of the paper. After transfer, the
paper moves to the Fuser where it passes between the
Heat Roll
and
the
Pressure Roll
. The combination of heat and pressure melts the
toner ima
g
e and bonds it permanently to the paper. The fused sheet of
paper is then transported to the output tray.

The Cleanin

the transfer process. The toner that the Cleanin
g
Blade removes is
collected inside the sealed EP Cartrid
g
e. Toner that is reclaimed from
the drum is not reused by the EP Cartrid

CHECK
POINT
Toner collected by cleaning is collected as left toner
and kept in the different room from that for the
unused toner. Transfer efficiency is more than 90%.
Transfer efficiency varies by the printing rate,
humidity environment. Also, left toner is not reused.
