5.6 Printrex Printer Self Test and Error Handling
5.6.1 Printer Self Test
To do the self test, place the printer in the local mode by pressing the Line/Local button.
Then press and hold the Paper Advance button while pressing the Line/Local button to
initiate the test. The buttons may be released once the test is started. In self test, the ERROR
indicator turns ON and the printout shown in Figure 5-1 is generated.
FIGURE 5-1. Self Test Printout
The self test printout continues until it is terminated by momentarily pressing the Paper
Advance button again. After the self test, the printer remains in local mode until the
Line/Local button is again pressed.
5.6.2 Printrex Printer Errors and Error Handling
The following conditions cause the front-panel ERROR indicator to light and fault signals to
be sent to the host.
Paper Empty:
When the printer detects a paper-empty condition, it stops printing, goes off line, sets the
Paper Empty line high, sets the Busy line high, sets the Fault line low and lights the ERROR
indicator. Normal operation resumes when a new paper roll is installed.
