Installing the Printhead
  • Turn the power switch off and make sure both the power cord and the printer communications cable are disconnected.
  • Open the side cover first, then the front cover.
  • Open the Printhead lever.
  • Make sure to note the new Printhead resistance before installing. See calibration instructions.

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.

  • Attach the strip plate to the front of the Printhead Assembly by tightening the two Phillips head screws.
  • Install media and ribbon (if applicable).
slide11

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

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

Plug in power cord and printer communications cable.

  • 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).

slide15

Turn the voltmeter/multimeter switch to VDC 200.

  • 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).
  • 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

  • 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.

Loosen the Idler Pulley bolt.

  • Gently side the Idler Pulley downward, releasing tension from the Main Drive Belt.
slide31

Disengage Main Drive Belt from the three pulleys.

  • Using a hex wrench, loosen the platen pulley hex screw that secures the platen pulley to the platen roller.
  • Remove the platen pulley.
  • Detach the ground chain from the platen roller bar.
slide32

Lift up the left end of the platen roller and carefully slide the platen bearing off of the metal platen roller bar.

  • Disengage the platen roller by lifting up the side with the platen pulley and shifting the right platen bearing to the left, removing it from the bearing opening.
  • Remove the platen roller.

Platen Roller Installation

  • Slide the platen bearing off the pulley side of the platen roller.
  • Insert the right side of the platen roller into the bearing opening.
slide34

*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).

slide35

Once the right side of the platen roller is correctly inserted into the right bearing opening, slide the left bearing onto the Platen roller bar and lower it into the left bearing dropout.

slide36

Attach the Ground Chain.

  • Attach the platen pulley to the Platen roller bar, tightening the platen pulley hex screw until it is snug.
