Printer Self-Test
A sequence of automatic tests is performed during printer power-up. If any
faults are detected at that time, an error message will display (see page 194).
Printer operation should also be verified before setting the printer for online
operation. This is done by running the printer internal self-test diagnostic
program, which will produce a selection of printed test labels. See Chapter 3,
“Configuring The Printer,” for instructions.
The Test Print program can be enabled from the printer through the TEST key
on the Primary Control Panel or through the Secondary Control Panel
Diagnostics menu and provides the capability for printing a variety of test
pattern labels.
NOTE: Before attempting to print test labels, the printer must be properly set
up for the type of media installed. (See the Printer Control menu
selections on “Printer Control Menu” on page 91).
Printing Test Labels
The printer has a built-in function that prints a selected number of test labels
or test patterns. The patterns are useful for isolating printer faults and
checking print quality.
