Discharging; Cleaning; Fusing - Epson AcuLaser CX11 Service Manual

EPSON AcuLaser CX11/CX11F

DISCHARGING

At the "Discharging" process, the charge on the paper is neutralized/removed by the
Detack Saw.
The Detack Saw contacts the back side of the paper. The charge created at the
"Secondary transfer" process is neutralized/removed to prevent the toner from
splattering around the metal parts.

CLEANING

At the "Cleaning (belt)" process, the toner remaining on the Belt surface is removed
after the toner image is transferred to the paper.
The Belt Cleaner contacts the Belt only when cleaning the Belt to prevent the toner
image formed on the Belt surface from being destroyed. The IBT Retract Motor
moves the Belt Cleaner to contact the Belt.
Toner remaining on the Belt surface is absorbed by the Cleaning Roll. Then, the
toner is absorbed by the brush and collected in the Waste Toner Box.

OPERATING PRINCIPLES

FUSING

At the "Fusing" process, toner is fixed on paper with heat and pressure.
Fuser Assy does not have a pressure roll, but has a Fuser Belt instead.
By MOT ASSY FSR drive, Heat Roll rotates and Fuser Belt is driven by the
friction. The inner structure of the Fuser Belt is, as shown in the figure below,
designed to generate a pressure on the Belt and the Heat Roll (Nip Part) to contact
them firmly each other.
The toner melts by the Heat Roll heated by the Heater Lamp in the Fuser Assy, and
then the toner is fixed on the paper by the pressure of the Fuser Belt.
