CHAPTER 4 OPERATION
g. Auto Delivery Jam
• When the fixing heater is started, the paper leading edge sensor (PS102) detects the
presence of paper.
• The paper group is not known or the paper last subjected to length detection is identi-
fied as being LTR or larger; under either of these conditions, the delivery sensor (PS3)
detects paper within 2 sec after the fixing heater starts.
• The size of the paper last subjected to length detection is identified as being LTR or
larger, and the delivery sensor (PS3) detects paper within 2 sec after the main motor
starts.
• While auto delivery is under way, the machine identifies the absence of a cartridge.
h. Door Open Jam
• During printing, the reader unit slide detecting switch (SW1) has detected movement
(sliding) for the reader unit.
• If the toner supply cover open/closed detecting switch (SW2) identifies the toner
bottle cover as being open during printing.
• If the toner bottle sensor (PS11) identifies the toner bottle as being displaced during
printing.
