Component-Related Paper Jam - Ricoh B121 Service Manual

3.2.2 COMPONENT-RELATED PAPER JAM

Motor-Related Paper Jam
The 1-bin tray unit does not know if the tray motor [C] is working properly. No error
message is displayed even when, for example, the tray-motor cable comes off the
1-bin tray board [B].
When the tray motor does not work properly, the leading edge of the paper is
caught by the exit rollers [A]. The paper stays between the exit rollers (of the 1-bin
tray unit) and the fusing unit. In this case, the copier controller detects that the
paper jam has occurred in the copier (not in the 1-bin tray unit). To get the copier
ready for normal operation, you must:
1) Remove the paper.
2) Open and close the right cover of the copier.
Solenoid-Related Paper Jam
The 1-bin base unit does not know if the
junction gate solenoid [E] is working
properly. No error message is displayed
even when, for example, the solenoid cable
comes off the 1-bin tray board.
When the junction gate solenoid does not
work properly, the junction gate [F] does not
lead the paper to the paper path [D]. The
paper stays between the paper exit rollers of the copier. In this case, the copier
controller detects that the paper jam has occurred in the 1-bin base unit. To get the
copier ready for normal operation, you must:
1) Remove the paper.
2) Open and close the right cover of the copier.
3) Open and close the base unit.
