Printronix MVP Series user manual Printer Fault Conditions, To Bypass Soft Fault

B Printer Diagnostics

MVP–Series printers sense printer faults and signal these faults with a lit CHK indicator and codes in the panel display. Table B–1 lists the fault codes and required actions. Some faults cannot be cleared or bypassed. In such cases, contact a qualified service representative to perform the repairs. Refer to the appropriate maintenance manual for supplemental tests.

Printer Fault Conditions

A steady or flashing CHK indicator signals a fault in the printer which must be corrected or bypassed before the printer can be placed on–line.

When a fault condition occurs, check for one of three situations:

•Flashing CHK indicator, which means the fault is user correctable.

•Steady CHK indicator, which means the fault is not user–correctable. Some non–correctable faults are soft faults ( that is, a memory checksum or pattern check) that can be bypassed (see “Bypass Soft Fault”).

•A three–digit code in the display panel, which identifies the fault code (see Table B–1 ).

To Bypass Soft Fault

To bypass a soft fault:

1.Press and hold the CHK switch.

2.Press and quickly release the RDY switch.

3.Release the CHK switch.
