Static Charge
Eliminator
The sheet is separated from the print
drum by the stiffness of the printed
sheet. This process is also referred to as
‘‘curvature separation.’’
The static eliminator reduces the
powerful static charge left on the sheet
by the transfer process. Malfunctions
of the static eliminator produce the
distinctive image defect that is described
in Section 8.5.

OPC
After the toner image is transferred
and the sheet travels to the fusing unit,
residual toner is cleaned from the OPC
drum surface.
The sweeper strip and cleaning blade
scrape any remaining toner off the OPC
drum. This toner falls into a reservoir
and is not used again; it stays in the
reservoir until the EP-ED cartridge is
replaced.
2.3.7 Fusing Process
Halogen Heater
Upper Fusing Roller
Toner
Paper
Lower Fusing Roller
After the transfer process, the toner
image is loosely held to the paper sheet
by electrostatic and adhesive forces.
At this stage, all of the toner could be
brushed off the page.
As the sheet passes between the upper
and lower fusing rollers, the toner melts
and is pressed into the sheet, thus
making a permanent image.
