Making Two-Sided Copies (2Nd Side) - Canon NP6251 Service Manual

CHAPTER 5 PICK-UP/FEEDING SYSTEM
B. Making Two-Sided Copies (2nd side)
When copying on the second side of a two-sided copy, pick-up occurs on the holding
tray.
When the Copy Start key is pressed, the bottommost sheet of the stack of copy
paper on the holding tray is moved to the holding tray registration roller as the holding
tray separation clutch (CL6) and the holding tray re-pick up roller solenoid (SL6) turn on
in response to the movement of the sheet.
The leading edge of the sheet butts against the holding tray registration roller, and
the sheet arches; then, it is set to the holding tray feeding assembly as soon as the
holding tray registration clutch (CL3) turns on.
The copy paper is then sent to the registration roller through the holding tray feeding
assembly.
