Print Test
Test the receipt station using the simple tests described in this section. To further test the
receipt station or to test the slip station, run the level 1 diagnostic tests described in “Level
1 Diagnostics” earlier in this chapter.
The tests described here print various settings which can be used to check the printer's
configuration. The settings are listed in “Level 1 Diagnostics.” The tests also print all
variations of the character sets with a partial cut between each variation. See the sample at
the end of this chapter. The sample does not show the character sets. The tests end with a
partial cut, then begin again. Several feet of paper can be used to print one pass of the test.
Running the Print Test by Power Cycling the Printer
Note:
The operator panel may differ depending on the model. To put the printer on- or
off-line, use a paper clip or other pointed object to depress the plunger (in place of the On
Line button) on models with that item.
1. Press and hold down the Paper Feed button on the top panel.
2. Press the On Line button (or plunger).
3. Let go of the Paper Feed button once the printing begins.
The printer begins printing the data and character sets (see the sample).
4. To stop the test, press the Paper Feed button.
The printer is ready to receive and print data from the host computer.
Running the Print Test by Opening and Closing the Cover
1. Open the receipt cover by pulling up on the front left side of the cover.
The LED (red) comes on indicating the receipt cover is open and that the printer
cannot receive or print data (not that the paper is out).
2. Press and hold down the Paper Feed button while closing the receipt cover.
3. Let go of the Paper Feed button once the printing begins.
The printer begins printing the data and character sets (see the sample).
