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. For additional technical support, you can use the
interactive Printer Troubleshooting Guide
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"
If an unexpected condition has occurred, take the following general steps:
1 Cycle the power of the printer and note its behavior.
