CHAPTER 7 PICK-UP/FEEDING SYSTEM

10. Fixer wraparound jam
It is judged there is a fixer wraparound jam if paper has wrapped around the fixer,
causing the delivery sensor to turn OFF within 1.4 seconds after the delivery sensor
(PS306) has detected the paper leading edge.
Figure 7-615
11. Door open jam.
If, during pick-up/feeding the front cover is opened, a door open jam will be detected
and the feeding process immediately stopped.
Furthermore, if the pick-up vertical path assembly cover is opened during pick-
up/feeding, a jam message will be displayed on the control panel, indicating there is a
pick-up feeding malfunction.
12. Forced delivery operation
When the jams listed below occur during multiple copy printing, the sheet prior to the
one which caused the jam (preceding sheet) will be left inside the machine. Therefore
the main motor is forced to rotate causing the sheet to be delivered out of the machine.
Note: Even if residual paper is detected at the time of the power supply being turned
on to the unit, automatic delivery does not take place.
< Types of forced delivery jams >
• Pick-up sensor delay jam
• Pick-up delay jam *
• Paper leading edge sensor delay jam*
* Jams at the time of cassette pick-up and multi-feeder pick-up.
