2100-Sheet Tray Pick Drive - Lexmark M52 Series Service Manual

2100‑sheet tray pick drive
The pick roller is lifted by the elevator plate until it triggers the sensor (pick roller index). At the pick position,
the pick roller rotates to pick the topmost paper. The motor (pick) drives the pick roller.
To avoid multi‑sheet picking, the friction from the separator pad prevents the extra paper from entering the
printer.
The sensor (paper present) detects if the tray is empty. Paper guide positions are also detected by sensors to
determine paper size.
