3.1.1 Potentiometer Adjustment

Pitch potentiometer
After the pitch has been set with the LCD control panel, it is sometimes desirable to make minor adjustments.
This can be done using the PITCH potentiometer on the front operator panel. This potentiometer is set at the
factory so that it has a range of ± 3.75 mm (± 0.15"). The midpoint setting should have no effect on the pitch.
Turning the potentiometer all the way clockwise should move the print position 3.75 mm (0.15") up towards
the top edge of the label. Turning it all the way counterclockwise should move the print position down 3.75
mm (0.15").
1. While depressing the FEED button on the front panel, power the printer on.
2. When you hear one beep from the printer, release the FEED button and the printer will ask for the type of
Test Label you want to print.
3. Use the LINE button to choose the CONFIGURATION selection and press FEED button to accept the
selection.
4. Use the LINE button to select the Test Label Size. After the size is selected, press the FEED button to
accept the selection and the printer will begin to print test labels continuously.
5. Adjust the PITCH potentiometer on the front panel until the first print position is at the desired location on
the label. If the potentiometer does not have enough range, then you will have to change the pitch setting
using the front panel display.
6. Press the FEED button to stop the printer.
7. To exit the Test Label mode, power the printer off and then back to on. Adjusting the PITCH potentiometer
will affect the stop position of the label.
Offset potentiometer
When a label is printed, it must be correctly positioned for dispensing and application. The Backfeed
adjustment is used to position the label so that it is fully dispensed and ready for application. It may then be
necessary to reposition the next label before printing. The Backfeed (repositioning of the label) operation is
enabled if DSW3-4 is in the OFF position. If Backfeed is enabled, placing DSW3-1 in the OFF position will
cause the backfeed operation to be performed immediately before each label is printed. If DSW3-1 is in the
ON position, the backfeed operation is performed as soon as the dispensed label has printed and taken from
the printer.
The amount of backfeed is controlled by the OFFSET potentiometer on the front operator panel. When turned
all the way clockwise, the amount of backfeed is +3.75 mm (+0.15"), and -3.75 mm (-0.15") when turned all
the way counterclockwise.
1. Turn the printer on.
2. Press the LINE button to place the printer in offline mode.
3. Press the FEED button to feed out a blank label.
4. Adjust the position using the OFFSET potentiometer on the operator panel and feed another label by
depressing the FEED button. Repeat this procedure until the label is fully released from the liner.
Print potentiometer
The PRINT potentiometer is used to adjust the amount of heat (that is, power) applied to the print head for
printing. It provides a continuous range of adjustment, allowing you to make precise changes. Maximum print
darkness is obtained by turning the potentiometer all the way clockwise and maximum counterclockwise
setting will give the lightest print.
Note:
The PRINT potentiometer adjustment will affect the darkness regardless of the speed and darkness ranges
setting.
