Key Combinations
Access to certain of the printer’s functions should be reserved for authorised
service technicians. Access to these functions has been restricted. In order
to access them, the operator must restart the printer while pressing a specific
key combination for several seconds.
Service Data
The status printout "Service status" lists the printer’s main service data.
Some of the counters contained in this function are incremented automatical-
ly, for example, the running time of the printhead. Other counters, such as the
number of printhead replacements, need to be incremented manually by the
service technician. This is done by using the appropriate parameter.
(Tab. 2).
