1. Attach the strip plate to the front of the Printhead Assembly by tightening the two Phillips head screws.

2. Install media and ribbon (if applicable).

After confirming the Printhead Cable Assembly is properly positioned into the Printhead connector, attach the two 7/32 hex nuts onto the Printhead bracket guide pins.

1. Clean the Printhead’s print-line using an alcohol swab, removing oil or dirt that may have been deposited during installation.

2. Lower the Printhead Assembly and close Printhead lever, checking the media and ribbon for proper alignment.

3. Carefully close front cover first, then the side cover.

Printhead Resistance Calibration

Printhead voltage should never be adjusted to affect print darkness. Changing Printhead voltage in this way will drastically reduce the life of the Printhead.

1. Plug in power cord and printer communications cable.2. With the printer turned off, attach the black probe of the

voltmeter to Ground (GND) on the logic board, and the red probe to the top of point F2 (the bottom-left fuse).

1. Turn the voltmeter/multimeter switch to VDC 200.2. Without removing the probes, turn the power on and wait for the

Power On Self-Test to be completed (usually takes between 10-15 seconds).

3. Find RV2 at the very bottom of the Main Logic Board and adjust with a small Phillips-head screwdriver until the voltmeter displays the correct value from Table 1 (as defined by the resistance value for this particular Printhead).

Toggle Position Adjustment

1. Before adjusting toggle pressure, perform a Pause Self-Test by holding the pause key while turning on power. If the print is not consistent across the width of the label, proceed to make toggle adjustments.

2. Turn the toggle adjusting nuts until appropriate pressure is achieved.a. Tighten (clockwise) to

increase pressure.b. Loosen (counter-

clockwise) to decrease pressure.Note that too much pressure applied to the toggles will

shorten the life of the Printhead. Choose the lowest even pressure that produces the desired print quality in order to maximize Printhead life.
