Operator Panel
Note: The operator panel may differ from the standard version (left) depending on the
model. On models matching the alternate version (right), use a paper clip or pointed object
to press the plunger to put the printer on- or off-line.
1. Press the On Line button (or plunger) to put the printer on-line, if it’s not already on-
line.
The printer goes through a self-test routine to ensure everything is working properly
then “beeps.” The On Line light (green) comes on indicating the printer is on-line.
When the printer has completed its “startup” cycle, it is ready to receive data.
If the On Line light does not come on, the On Line light or Paper Out light flashes, or
the host computer indicates that there is a problem, see “Chapter 4: Troubleshooting”
for more information.
2. Press the On Line button (or plunger) again to put the printer off-line.
Note: The printer receives power when the power supply is on even if the printer is off-
line. To completely remove power, press the On Line button (or plunger) to put the printer
off-line (On Line light is off), then unplug the power supply from the outlet.
Testing the Printer
Before testing the printer, be sure to load the paper. See either the User's Guide or the
Owner's Guide for instructions on loading the paper.
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” in “Chapter 3: Diagnostics.” See “Chapter 4: Troubleshooting” for what to
do if the printer is not functioning properly.
The tests print various settings which can be used to check the printer's configuration. The
settings are listed in “Chapter 3: Diagnostics.” The tests also print all variations of the
character sets with a partial cut between each variation. See the samples at the end of this
chapter. The tests end with a partial cut, then begin again. Several feet of paper can be used
to print one pass of the test.
