Fault Correction Procedure

STEP 1.
STEP 2.
STEP 3.
STEP 4.
This chapter deals with troubleshooting problems on the T6090 printer. Messages that
indicate printer faults and errors are explained and corrective action given. The few
paper handling and print quality problems that may occur are also explained. Trouble-
shooting tables and diagnostic flow charts have been included.
Messages on the Control Panel Display report both normal operation and fault situa-
tions. In Table 3–1 we present a listing of the Display Messages that need explanation
or action on the part of the operator or repair person. Each message listing includes
causes and corrective actions where necessary.
When a fault occurs, it will cause the printer to cease operation and go Offline. The
printer alarm will sound, the FAULT Indicator will illuminate, and the display will
report a fault message.
In some cases it is possible to clear an error message and continue using the printer by
depressing the CLEAR Key. However, the quality of the print may be questionable and
collateral damage to other parts may result. If the fault message returns, perform the
required corrective action.
If a nondestructive fault occurs in the middle of printing a document, one line of text
may be lost after the error condition is corrected and the printer put back Online.
If the fault is in the control panel or interprocessor link, the fault message may not
be displayed, and the beeper and FAULT LED may not operate.
First check the fault message on the Control Panel Display and look it up in the Fault
Message tables provided later in this chapter.
Perform the required corrective action. Some Fault and Error messages will automati-
cally clear as soon as the problem is corrected (for example, the Platen Open message
will clear when the Form Thickness lever is lowered to the proper thickness).
If a faulty piece of hardware is found, turn to Chapter 4: Removal/Replacement Proce-
dures, for instructions on removal and replacement of faulty parts.
If any other faults appear on the display after you have corrected the original problem,
go back to Step 1 and perform required corrective actions for the new problem. Other-
wise place the printer back Online and test it during normal print operations.
