Overview

This chapter discusses a number of topics related to troubleshooting the
printer. It covers the generation and use of the pre-programmed configuration
and print quality test labels, the printer power on self test, error messages
and their causes, and some techniques for isolating and correcting faults .
When faults are isolated to the Printer Controller or Secondary Operator's
Panel PCBAs, it is recommended that the entire PCBA be replaced as it is
not generally feasible to provide component level service to these boards in
the field. Insertion and removal instructions are provided only for socketed
components (e.g., DRAM, EPROM, etc.) and for jumper settings.
NOTE: There are different procedures for printing pre-programmed labels

Printing Pre-programmed Labels

The printer is pre-programmed to produce both configuration and print quality
test labels. The configuration label is used to quickly determine the exact
configuration of the printer. The print quality test label is designed to aid in
checking and adjusting the printhead and ribbon.
In general it is good practice to print a configuration label as a first step to
any maintenance or troubleshooting procedure, providing that the unit is
functional enough to do so. The information contained on the label should be
compared to the desired setup to confirm that the configuration is correct. A
copy of this label should be kept with the printer for comparison to possible
subsequent configurations, and to ensure that the current configuration is
correct.

LP+, IGP/PGL, IGP/VGL Labels

Printing configuration and print quality test labels is performed by selecting
the appropriate menu sequences from the Secondary Operator's Panel as
described in Chapter 3 of the LP+, IGP/PGL, IGP/VGL Setup Guide (Printing
a Configuration and Diagnostic Menu Options, respectively).

IGP/FGL Labels

Printing configuration and print quality test labels is performed by selecting
the appropriate menu sequences from the Secondary Operator's Panel as
described in Chapter 5 of the IGP/FGL Setup Guide.
