Theory of Operation
Print unloading
To unload the print after printing, the drum rotates clockwise until the trailing edge of the
paper flips out into the exit path, then the drum motor rotates the drum counterclockwise
to the clamp-open position. This also pushes the print to the lower exit rollers. The
paper-feed motor, running backward for a set amount of time, drives the lower and upper
exit rollers, which pull the print through the rollers and out to the printer's output tray.
The print engine checks to make sure that the paper's trailing edge has passed the
paper-exit sensor. After a set amount of time, the drum rotates to park the paper clamp
under the bail rollers (to prevent them from denting the drum). Then the paper-feed
motor is turned off, completing the print process.
