   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
Toggle Position Adjustment

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

   the bearing opening.

34
Make sure that the bearings are rotated
correctly for either the S400 or the S600. For
the S400, the bearing hole should be on top. The
S600 rotates the bearings 180 degrees (the
bearing hole is toward the bottom).
Make sure that the bearings are rotated
correctly for either the S400 or the S600. For
the S400, the bearing groove should be on the
bottom. The S600 rotates the bearings 180
degrees (the bearing groove is toward the top).
