Service information
There are three levels of service code information.
•
Primary service error codes
•
Secondary service error codes
•
Subcodes (sub set of the secondary codes)
Service information is displayed whenever the printer is in the check
state, and needs servicing. In general, service errors are not
recoverable. However, it may be possible to turn the printer off and
back on to temporarily recover from the error condition if it is
intermittent.
When a service error occurs, the printer stops printing immediately.
The only recovery is to turn off the printer.
The following operator panel is an example indicating a primary
service error code condition.
•
Brief button press displays a service error code pattern.
•
Long button press displays a service error code pattern.
•
Double button press is not available.
•
Open/close cover is ignored.
