112 MFP unit explanation ENWW
*1 Fuser heater lamps
Two halogen lamps are used for the
fuser upper roller and one halogen lamp
is used for the fuser lower roller to
reduce the warm-up time and ensure
reliable fuser.
*2 Cleaning
Cleaning web is used to clean the fuser
upper roller. The web SD (SD2) in the
MFP turns on/off to drive the cleaning
web wind-up shaft via the ratchet
mechanism and gears, thus supplying
cleaning web from the cleaning web
unwinding shaft. SD2 is controlled
according to the copy count, and
cleaning web supplied about 0.025 to
0.05 mm/copy. Cleaning web containing
silicon oil is pressed against the fuser
roller (upper) by the pressure roller.
*3 Decurler
The paper guided by the reverse/exit
selection gate is decurled while it
passes between the decurler roller and
restriction shafts. The decurler roller is
driven by the fuser roller (upper) via
gears.
*4 Jam detection
When a jam occurs in the fuser exit
section, the paper exit guide plate
(lower) is pressed down, causing the
fuser exit PS (PS30) to detect a jam via
the jam detection plate and actuator.
