2.5. PAPER FEED
The paper feed motor [A] drives the feed roller [B] and the relay roller [C].
The paper feed clutch [D] turns on when the unit feeds a sheet of paper from
the cassette. It transfers the motor drive to the feed roller until the paper
reaches the relay sensor [E].
If only one paper feed unit is installed:
The host machine’s paper feed motor feeds the paper into the printer
mechanism after the leading edge of the paper passes the host machine’s
registration sensor.
If two paper feed units are installed:
The feed motor in the upper paper feed unit feeds the paper to the fax
machine’s registration area after the leading edge of the paper passes the
feed unit’s relay sensor. The fax machine’s paper feed motor then feeds the
paper into the printer mechanism.
Jam Conditions
A jam condition is detected when one of the following conditions occurs:
1. The relay sensor does not activate 2 s after the paper feed clutch was
turned on [error code 9-50 or 9-52].
2. The registration sensor in the fax machine does not activate 2 s after the
relay sensor in the paper feed unit was activated [error code 9-51].
3. The relay sensor in the upper paper feed unit does not activate 2 s after
the relay sensor in the lower paper feed unit was activated (when two pa-
per feed units are installed) [error code 9-53].
