POTENTIOMETER 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

VOLUME	Adjusts the audible decimal level for error indication. Power on
	the printer, place on-line, and open the print head. When the
	beep is emitted, adjust the volume level accordingly.

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 postion. Thusly, if using a dispenser or cutter, adjust the
	Offset first and then the Pitch.

OFFSET	The offset adjustment is used to reposition the media for
	printing following advancement for dispensing or cutting. A label
	is printed, it is fed forward for dispense, the printer retracts the
	remaining media (offset) to print the next label. To preform this
	adjustment:
	1.	Power On the printer.
	2.	Press the LINE key to place printer offline.
	3.	Advance to the User Mode and press ENTER.
	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.
