This self test can be used to provide the test printouts required when making adjustments to the printer’s mechanical assemblies. See the sample printout in Figure 3.3.
FEED Key Test
The CANCEL Key Self Test should be performed before this self test.
Information on the “ Configuration” printout (CANCEL Key Self Test) will be used with the results of this self test to determine the best Darkness Setting for a specific media/ribbon combination.
The FEED Key Self Test printout will print at various PLUS or MINUS Darkness settings relative to the Darkness value shown
on the Configuration Label. This test makes 7 printouts at speeds “ A” (2" per second) and “ C” (4" per second). Inspect these printouts and determine which one has the best darkness setting for the application.
The value on that printout is added to (plus) or subtracted from (minus) the “ Darkness” value specified on the Configuration printout.
The resulting numeric value (0 to 30) is the best darkness value for that specific media/ribbon combination.
The plus or minus value can be entered by the operator while performing a Label Darkness Adjustment procedure. Enter the PLUS value by pressing the UP (FEED) key, or enter the MINUS value by pressing the DOWN (CANCEL) key the appropriate number of times.
Optionally, the Darkness value can be programmed into the ZPL II formats
