The measured temperature value or the measured humidity value of the Temp and Humidity Sensor is out of the specification range. (This Fail is a hidden failure and it is registered only in the History)
Fault Code
041-603: EPG Temperature Sensor Fail
041-604: EPG Humidity Sensor Fail
Influence
As the control for temperature or humidity cannot be performed when this Fail occurs, image density error (too dark, too light) might occur due to changes in the temperature or humidity.
Procedure
Perform Procon On Print (ADJ 18.1.11) in Service Mode and check the result of [Temperature Fail] or [Humidity Fail].
Is the result OK?
Y N
Turn OFF the power and disconnect the power plug. Check the connection between the Temp and Humidity Sensor (ReC/ADC Sensor Assembly) J151 and the Motor Drive PWB J416 for open circuit, short circuit, and poor contact.
If no problem is found, replace the following parts in sequence: However, each time a parts is replaced, check whether the Fail is still occurring and return the part if it has no problems.
ReC/ADC Sensor Assembly (PL 6.1, PL 6.2)
NOTE
After replacement of ReC/ADC Sensor Assembly, go to the Diag mode and perform DC675 Registration Control Setup Cycle (ADJ 18.1.5) then DC937 Procon On Print
(ADJ 18.1.11) in sequence.
Motor Drive PWB (PL 18.2, PL 18.5)
Run Procon On Print continuously for several number of times.
Does the Fail occur?
Y N
No action necessary.
Replace the following parts in sequence. However, each time a parts is replaced, check whether the Fail is still occurring and return the part if it has no problems.
ReC/ADC Sensor Assembly (PL 6.1, PL 6.2)
NOTE
After replacement of ReC/ADC Sensor Assembly, go to the Diag mode and perform DC675 Registration Control Setup Cycle (ADJ 18.1.5) then DC937 Procon On Print (ADJ 18.1.11) in sequence.
