Chapter 1 Troubleshooting
11
Checking the Cassette Feed Solenoid (SOLENOID FEED)
for operation
Does the Cassette Feed Solenoid (SOLENOID FEED)
operate properly?
Checked by [Digital Output] - [DO-31] in [IOT Diag] of
diagnosis.
During this check, cheat the interlock switch (HARN ASSY
INTERLOCK).
Replace the
CASSETTE ASSY
250 OPT.
Go to step 22.
12
Checking the Feed Clutch (CLUTCH ASSY DRV) for
operation
Does the Cassette Feed Clutch (CLUTCH ASSY DRV)
operate properly?
Checked by [Digital Output] - [DO-33] in [IOT Diag] of
diagnosis.
During this check, cheat the interlock switch (HARN ASSY
INTERLOCK).
Go to step 13. Go to step 26.
13
Checking the paper lead edge staying position
Does the paper lead edge stay before the ROLL ASSY
REGI and ROLL REGI METAL?
Go to step 14.
Replace the
FEEDER ASSY
OPT.
14
Checking the paper path
Remove the Tray 1 and Tray 2 paper cassettes.
Are there any obstacles on the paper transfer path between
the Tray 2 and the Regi Assy? Remove the
obstacles or stains
from the paper
transfer path.
Replace the
FEEDER ASSY
OPT.
15
Checking the connectors of the SENSOR PHOTO (Paper
Path Sensor) for connection
Check the connections between the PWBA FFE D and
SENSOR PHOTO.
Are P/J420 and P/J4200 connected correctly?
Go to step 16.
Reconnect the
connector(s) P/
J420 and/or P/
J4200 correctly.
16
Checking the HARN ASSY TRAY COMP for continuity
Disconnect J420 from the PWBA FEED H.
Disconnect J4200 from the SENSOR PHOTO.
Is each cable of J420 <=> J4200 continuous?
Go to step 17.
Replace the
HARN ASSY
TRAY COMP
17
Checking the power to the SENSOR PHOTO
Disconnect J420 from the PWBA FEED H.
Is the voltage across P420-6pin <=> ground on the PWBA
FEED H, about +3.3 VDC?
Go to step 18.
Replace the
PWBA FEED H.
18
Checking the SENSOR PHOTO for operation
Check the voltage across J420-5pin <=> ground on the
PWBA FEED H.
Does the voltage change, when the actuator (ACTUATOR
REGI IN) is operated?
Replace the
PWBA FEED H.
Replace the
SENSOR PHOTO
(Paper Path
Sensor).
19
Checking the connectors for connection
Check the connections between the PWBA FEED H and
MOTOR ASSY SUB.
Are P/J422 and P/J211 connected correctly?
Go to step 20.
Reconnect the
connector(s) P/
J422 and/or P/
J211 correctly.
20
Checking the HARN ASSY TEAY MOT for continuity
Disconnect J422 from the PWBA FEED H.
Disconnect J211 from the MOTOR ASSY SUB.
Is each cable of J422 <=> J211 continuous?
Go to step 21.
Replace the
HARN ASSY
TRAY MOT.
21
Checking the power to the MOTOR
Disconnect J422 from the PWBA FEED H.
Are the voltages across J422-6pin <=> ground on the
PWBA FEED H, about +24 VDC when the interlock switch
(HARN ASSY INTERLOCK) is pushed?
Replace the
MOTOR ASSY
SUB.
Replace the
PWBA FEED H.
