OPERATIONAL ADJUSTMENTS

These operational adjustments are for fine tuning the printer as necessary following the configuration process and are largely confined to the four potentiometers located on the operator panel. Refer to the table below for their function.

POTENTIOMETER		DESCRIPTION/PROCEDURE

PITCH	Is to be used in conjunction with the configuration adjustments. Make course
	adjustments there and then fine tune here. If unable to achieve the desired
	setting here, the course adjustment must be reset. Adjust this potentiometer as
	labels are being printed. Allow two labels to be printed for each adjustment to
	ensure a desired setting.
	Adjustment of the PITCH potentiometer will affect the print offset position.

OFFSET	The offset adjustment is used to reposition the media for printing following
	advancement for dispensing. A label is printed, it is fed forward for dispense, the
	printer retracts the remaining media (offset) to print the next label. To perform
	this adjustment:
	1.	Power On the printer.
	2.	Press the LINE key to place printer offline.
	3.	Advance to the User Mode and press FEED.
	4.	Adjust the OFFSET potentiometer.
	5.	Press the FEED key to feed another label.
	6.	Repeat steps 3 and 4 until properly adjusted.
	7.	Press the LINE key to bring the printer back online.

DARKNESS	Is used to adjust the darkness or lightness of the printed image and should be
	used in conjunction with the configuration adjustments. Make course
	adjustments there and then fine tune here. If unable to achieve the desired
	setting here, the course adjustment must be reset.
	Adjust this potentiometer as labels are being printed. Allow two labels to be
	printed for each adjustment to ensure a desired setting.
