Initial issue
Status Indicator RAPs
8-620 Regicon Temp Sensor
Environment Sensor not in range.
Procedure
NOTE: Machine operation continues. Status Code not displayed on UI. Status Code logged in
History.
Turn the power off. Disconnect the Environment Sensor (PL 1.3).
Refer to Figure 1 and measure the resistance between the following:
• I/F PWB P/J536-B4 and P/J255-1
• I/F PWB P/J536-B2 and P/J255-3
• I/F PWB P/J536-B1 and P/J255-4
The Resistance is 1 ohm or less.
YN
Check the wires and connectors. If the check is OK, replace the replace MCU PWB (PL
13.1).
Measure resistance between P/J255-3 and P/J255-4 on Environment Sensor. 6k ohms to
20k ohms is measured.
YN
Replace Environment Sensor (PL 1.3).
Replace MCU PWB (PL 13.1). If problem continues, replace ESS PWB (PL 13.1).

8-622 Regicon Data Overflow (A1 Patch X)
At A1 patch detection, the XSO correction setting value for either Y, M, C, or K exceeds the
setting range (NVM value 0 to 472).
NOTE: Status Code not displayed on UI. Machine operation continues.
Procedure
Check the IBT Belt and Drum for a scratch or contamination. The check is OK.
YN
Replace as required.
Adjust the Color Registration (ADJ 9.6).
