WorkCentre C2424 Service Manual
Transfixing and Exiting
Transfixing and exiting consists of four major functions:
1.
Stage the paper for rendezvous with the image on the drum and transfix roller
nip.
2.
Load the transfix roller and engage the drum stripper blade assembly.
3.
Strip the paper from the drum.
4.
Exit the paper from the system, or exit the paper for 2-sided printing.
Tripping the preheat exit sensor sets up a series of events that occur on a
predetermined schedule. Paper is transported through the preheater to thermally
prepare it for transfixing. The preheat sensor detects the paper’s presence and
accurately references the leading edge of the paper with the image on the drum. Based
on the timing information from the paper preheater exit sensor, the transfix roller
lowers onto the leading edge of the media in the nip. Timing is based on the sensor
ensuring the image is perfectly aligned for transfix to the paper. The process drive lifts
and lowers the transfix roller.
At the point which the transfix roller is loaded, but before the drum begins to rotate,
the paper stripper solenoid is engaged. The paper stripper is actuated by energizing
the paper stripper solenoid. The solenoid mounts on the upper inner duplex guide and
activates the strip solenoid lever. The lever rotates the paper release carriage until it
hits the transfix ground pins, causing the paper release blade to momentarily drop
onto the deadband of the drum. This action catches the leading edge of the sheet of
paper and guides the paper to the rotating exit rollers.
After the transfix roller is engaged, the drum rotates to advance the paper and transfix
the image. All gears move to rotate the drum transfix camshaft to bring the transfix
roller into contact with the drum. The transfix roller nip applies the load necessary to
transfer the image to the paper from the drum. Once the image is transferred, the drum
stops rotating and the transfix roller is lifted by the process drive.
