Troubleshooting the printer
The A760 ColorPOS
®
printer is a simple, generally trouble-free printer, however unexpected
conditions my arise. For example, the power supply may be disconnected or the thermal
printhead may overheat.
The on-line, paper status, error LED on the operator
panel may signal that something is wrong. The light on
the front right side of the printer is used only to indicate
when a form is inserted properly. It does not indicate an
error.
For some unexpected conditions, the printer
communicates the information to the host computer and
relies on the application to indicate what the condition
is.
The information on the following pages describes some
conditions that you may encounter: conditions that you
can easily fix, and others that you will need to contact a
service representative for.
You may be able to correct many of the conditions
without calling for service. However, if a condition
persists, contact a service representative. See
“Contacting a service representative” at the end of this
chapter.
If an unexpected condition has occurred, take the
following general steps:
1 Cycle the power of the printer and note its behavior.
2 Check the on-line, paper status, error LED and
compare its behavior to the following table.

3 Test the receipt printer or slip printer by printing a
sample test print as described elsewhere in this
document.
4 Determine if the condition is with the thermal receipt
printer or the impact slip printer and refer to the
tables on the following pages.
If unexpected conditions arise while installing the USB
driver, take a look in Appendix A: USB Driver
Installation, “Installation troubleshooting” on page 62.
