Status Indicator RAPs
Initial Issue
062-277 ESS-DADF Communication Fail RAP
BSD-ON:
BSD 3.5 - ESS-DADF Communication
Communication cannot be established between the ESS PWB and the DADF PWB.
NOTE: When turning the power OFF, turn OFF the power switch first and then the main power
switch.
Procedure
1.
Turn the power OFF and ON.
2.
Turn the power OFF and check the following:
•
The connectors of the ESS PWB
P/J390
and the IIT PWB
P/J7192
for damage, for-
eign substances, bent connector pins, burns, and improper soldering on the PWB
•
The connection between the IIT PWB
P/J7501
and the DADF PWB
P/J751
as well
as between the IIT PWB
P/J7502
and the DADF PWB
P/J752
for open circuit, short
circuit, and poor contact
•
The connectors of the IIT PWB
P/J7501
,
P/J7502
and the DADF PWB
P/J751
,
P/
J752
for damage, foreign substances, bent connector pins, burns, and improper sol-
dering on the PWB
If no problems are found, replace the following parts in sequence:
•
Reload the machine software (
GP 16
).
•
DADF PWB (
PL 51.2
)
•
ESS PWB (
PL 35.2
)
•
IIT PWB (Switch the EEPROM) (
PL 1.6
)
062-300 Platen Interlock Open RAP
BSD-ON:
BSD 6.7 - Platen Document Sensing
The Platen Interlock is open.
NOTE: When turning the power OFF, turn OFF the power switch first and then the main power
switch.
Procedure
Check the following:
•
The DADF for improper closing.
•
The Platen Close Sensor for failure:
Component Control
[062-300] (
PL 1.3
).
•
The connection between the Platen Close Sensor
P/J7251
and the IIT PWB
P/J722
for
open circuit, short circuit, and poor contact
•
The connection between the IIT PWB
P/J7192
-30 and the ESS PWB
P/J390
-11 for open
circuit, short circuit, and poor contact
If no problems are found, replace the following parts in sequence:
•
Reload the machine software (
GP 16
).
•
ESS PWB (
PL 35.2
)
•
