4.10.2 Types of Misfeed Detection and Detection Timings
The following are the types of misfeed detection and detection timings for different misfeed locations.
Note: For misfeed detection types and detection timings of options, see the relevant option's information
in the Section 6 on this service manual.
<Machine Take-Up Misfeed>
Type
Paper take-up failure
detection
<Optional Manual Bypass Take-Up Misfeed>
Type
Bypass paper take-
up failure detection
<Separator Misfeed>
Type
Leading edge
detection by Paper
Exit Sensor PC3
Trailing edge
detection by
Synchronizing Roller
Sensor PC2
Paper is stationary
Size error detection
Paper left
Excludes the period of time during which the paper is stationary before the Synchronizing Roller.
Detection Timing
1st Drawer paper take-up:
Synchronizing Roller Sensor PC2 is not unblocked (H)
even after the lapse of T sec. after Paper Take-Up
Solenoid SL1 has been energized for the second paper
take-up retry sequence.
2nd Drawer paper take-up:
PC2 is not unblocked (H) even after the lapse of T sec.
after SL1 has been energized for the first paper take-up
retry sequence.
1st/2nd Drawer paper take-up:
PC2 is unblocked (H) within T sec. after SL1 has been
energized.
Detection Timing
PC2 is not unblocked (H) even after T sec. after Manual
Feed Paper Take-Up Clutch CL3 has been energized.
PC2 is unblocked (H) within T sec. after CL3 has been
energized.
Paper left Manual Feed Paper Take-Up Sensor PC8 is
blocked (L) when the Power Switch is turned ON, CPU is
reset, or cover is opened and closed.
Detection Timing
PC3 is not blocked (L) even after the lapse of T sec. after
PC2 has been unblocked (H).
PC2 is not blocked (L) even after the lapse of T sec. after
it has been unblocked (H).
PC2 is blocked (L) within T sec. after it has been
unblocked (H).
During a sequence of detecting a paper size based on the
period of time between when Synchronizing Clutch CL1 is
energized and when PC2 is blocked (L), the paper size
detected is longer than the size data sent from the
controller by +260 mm or more.
The paper size detected based on the period of time
between when CL1 is energized and when PC2 is blocked
(L) is more than the size data sent from the controller by
±20 mm or more.
PC2 is unblocked (H) when the Power Switch is turned
ON, CPU is reset, or cover is opened and closed.
