[Master Eject Misfeed Detection]
The misfeed indicator for the master eject section blinks in the following
cases:
Case 1: The master eject sensor is not activated and the drum has turned
50 degrees more (still in reverse and after de-activation of the
master eject solenoid). The machine knows that the eject rollers
have failed to catch the master. So the drum returns 68 degrees (in
the printing direction) to repeat the master eject process once
again. The master eject solenoid is again energized while the drum
turns another 18 degrees to try to catch the master.
If the master eject sensor once again fails to detect the master,
then the drum returns to its home position and the misfeed
indicator blinks.
Case 2: The drum finishes its rotation for the master ejecting process and
retuns to the home position, but the master eject sensor does not
turn off. This means that the master is still in between the master
eject rollers, the misfeed indicator blinks.
