ADF document feed control ADF document feed control is performed to pass paper over the optical units for exposure. The ADF document feed control process begins when the SCB sends signals. The shutter solenoid helps to align the paper, and the weight plate “slaps” down on the stack of paper. Note Both the shutter solenoid and the weight plate help to perform the pickup process. The pickup motor drives the pickup rollers and the feed rollers, and then reverses rotation to drive the registration rollers. ADF document feed control terminology STSOL: shutter solenoid PMOT: pickup motor WTSOL: weight solenoid DMOT: delivery motor Figure 55.
