Endurance test
The endurancetest prints continuously a test pattern. There are two possibilities to start
this test:
1. By diagnostic menu. If the Endurancetest was started from diagnostic mode menu,
the test can be aborted by pressing the LF-Button for more than 1 second.
2. After power up or printer reset with the help of a short circuit plug. Additionally
the endurance test must be enable by memory switch (see page 98). If the short
circuit plug started the Endurancetest, the test can be aborted by removing this
plug.
Interface Description
USB The pins 1 and 4 (5V and GND) of the plug have to be
shortened.
RS232 The pins 6 and 20 (DSR and DTR) of the plug have to be
shortened.
There are two modes available in which the Endurancetest is working.
a. If the linefeed button is pressed while the printer is switched on, the endurance
test is executed in endless mode. In this mode, test tickets will be printed until
the power is switched off.
b. If the linefeed button is not pressed while switching on the printer, the endurance
test prints a predefined number of tickets. In limited mode printing stops after a
determined count of tickets. The number of tickets can be defined by the
command GS ( E(fn = 5) (see page 94). After printing the predefined number of
tickets a self test printout is executed).
Note: In case of paper end or cover open the printer performs a automatic reset. Except if
the endurance test starts by short circuit plug, the printer will continue if cover closed
again or new paper is inserted.
When starting the Endurancetest by USB plug, the test is executed always in limited mode.
But if the linefeed button is pressed while switching on or resetting the printer, the
Endurancetest is executed in endless mode.
