Misfeed Detected Types and Detection Timings

• The following table lists the types of misfeed detection classified by the misfeed locations
and their corresponding detection timings.
Note
For the misfeed detection types and detection timings in the options, see the Service Man-
ual for the options.
<Paper Take-up Misfeed>
Type
Paper take-up failure 1st Drawer Paper Take-Up Sensor PC55 is not blocked (L) after
detection the lapse of approx. 2.4 seconds after 1st Drawer Paper Take-
Up Solenoid SL2 has been energized during the third paper
take-up retry sequence.
2nd Drawer Paper Take-Up Sensor PC56 is not blocked (L) after
the lapse of approx. 2.4 seconds after 2nd Drawer Paper Take-
Up Solenoid SL3 has been energized during the third paper
take-up retry sequence.
Paper take-up trailing PC55 is not unblocked (H) after the lapse of T seconds (which
edge detection varies for paper sizes) after it has been blocked (L).
PC56 is not unblocked (H) after the lapse of T seconds (which
varies for paper sizes) after it has been blocked (L).
Leading edge detection PC51 is not blocked (L) after the lapse of approx. 1.7 seconds
by Transport Roller Sen- after PC55 has been blocked (L).
sor PC51
PC51 is not blocked (L) after the lapse of approx. 2.5 seconds
after PC56 has been blocked (L).
<Multi-Bypass Misfeed>
Type
Paper take-up failure PC51 is not blocked (L) after the lapse of approx. 2.7 seconds
detection after Manual Feed Paper Take-Up Clutch CL51 has been ener-
gized during the third paper take-up retry sequence.
Leading edge detection PC54 is not blocked (L) after the lapse of approx. 2.5 seconds
by Paper Leading Edge after Paper Transport Clutch CL2 has been energized.
Detecting Sensor PC54
<Transport/Separator Misfeed>
Type
Trailing edge detection PC51 is not unblocked (H) after the lapse of T seconds (which
by Transport Roller Sen- varies for paper sizes) after the TRON signal has been input.
sor PC51
Leading edge detection PC54 is not blocked (L) after the lapse of approx. 1.5 seconds
by Paper Leading Edge after PC51 has been blocked (L).
Detecting Sensor PC54
Trailing edge detection PC54 is not unblocked (H) after the lapse of approx. 1.6 sec-
by PC54 onds after PC51 has been unblocked (H).
