Process Caution Infrormation; Display Procedure; List; Solution - Konica Minolta BIZHUB C3100P Service Manual

2. PROCESS CAUTION INFRORMATION

2.1 Display procedure

• The machine's CPU performs a self-diagnostics function that, on detecting a malfunction, gives the process caution information in the report
that is output by [SERVICE MODE] -> [PRINT MENU] -> [MANAGEMENT LIST].
I.3.8.1 MANAGEMENT LIST
• When receiving the process caution information, user can continue printing. However, as the information indicates that some error has
occurred in the image stabilization process, the error must be addressed rapidly.

2.2 List

• If an image stabilization fault occurs, the process caution information is provided.
