Tally T6215 Maintenance Manual - Introduction

Chapter 3.  Faults and Troubleshooting

3–1

Introduction

This chapter deals with troubleshooting problems on the T6215 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.  Troubleshooting

tables and diagnostic flow charts have been included.

Messages

Messages on the Control Panel Display report both normal operation and fault situations.

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.

Faults

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.

Fault Correction Procedure

Step  1.

First check the fault message on the Control Panel Display and look it up in the Fault

Message tables provided later in this chapter.

Step  2.

Perform the required corrective action.  Some Fault and Error messages will automatically

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).

Step  3.

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.

Step  4.

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.  Otherwise

place the printer back Online and test it during normal print operations.
