3.5 Trouble isolation function
• The trouble isolation function enables you to control MFP temporarily isolating faulty units, options, and functions where the trouble
isolation function can be applied when trouble occurs. This allows you to continue using the other units or functions that are not affected
and reduce down time that continues until CE resolves the problem.
• This function can be selected for the following units and options.
• Tray 1
• Tray 2
• Tray 3
• Scanner
• ADF
• Expansion Fun. (Storage)
• If a problem occurs with the units where the trouble isolation function can be applied, the control panel displays a trouble code and a key
with which you decide whether to continue using the MFP. When you press down the key, the control panel displays the units that will be
isolated as well as the next confirmation key with which you decide to continue.
• When you press down the confirmation key, the message on the control panel asks you to turn OFF and ON the main power switch. After
turning OFF and ON the main power switch, the MFP starts operating, isolating the faulty units or functions.
The message on the control panel also tells that the MFP is working, isolating the faulty units.
• To temporarily isolate faulty units and continue using the MFP with the trouble isolation function, be sure to make the above mentioned
control panel operation. The faulty units cannot be automatically isolated.
NOTE
▪ The malfunction detection mechanism is not applied to units and options that are being isolated.
