Autocompensator Mechanism (Acm); Key Components; Sensors - Lexmark MS510 Series Service Manual

Aside from providing rotational motion to rollers and feeders, the gearbox must also ensure that the print image is not
distorted during the whole process. It must also provide easy and effective means to cut or break the transfer of motion
when taking the cartridge unit out of the machine, or when clearing jammed sheets through its linkage system.

Autocompensator mechanism (ACM)

The fundamental function of the ACM is to pick and feed a single sheet of media and accurately deliver it to the
downstream paper path. The pick arm is counterbalanced to provide a priming force throughout the entire range of
paper levels in the tray. When media is picked, a subsequent sheet is not picked until the previous sheet's trailing edge
is detected by the trailing edge sensor. Once the trailing edge of the media is detected, and the minimum interpage
gap is satisfied, the next sheet will be picked.
