2. MALFUNCTION CODE
2.1 Display procedure
• The machine's CPU performs a self-diagnostics function that, on detecting a malfunction, gives the corresponding malfunction code and
maintenance call mark on the control panel.
• Touching the maintenance call mark will display the corresponding malfunction code on the state confirm screen.
2.2 List of the malfunction code
• If an image stabilization fault occurs, the corresponding malfunction code appears.

IDC sensor failure
P-5
• During IDC sensor light intensity correction, IDC sensor output is uncompleted.
• During IDC base surface detective control, sensor output voltage detected is under 0.7 V or over 3.35V.
• During image stabilization (gamma correction control), detected output value for IDC sensor did not go
below threshold (half the value of what is detected by IDC sensor on the belt surface) for three
consecutive times (position of the pattern end is not detected).
• Transfer belt unit
• IDC sensor (IDCS1)
• High voltage unit (HVPS)
• Base board (BASEB)
