2-4 Phaser 5500 Printer Service Manual
Paper Handling
Paper is driven along the paper path by various drive motors, belts, gear assemblies
and rollers. Synchronization of these components is managed by the Engine Logic
Board. The operating system monitors sensors located along the paper path
throughout the print engine and attached options. As a sheet travels along the paper
path, sensors change state temporarily to indicate the sheet’s presence. If the pattern
of sensor state changes differs from the expected timing for a particular paper size and
path, an error is reported.
