Removing the Printhead

Removingthe Printhead

  • Turn the power switch off.

  • Disconnect the power cord.

  • Disconnect the printer communications cable.

  • Carefully open the right side cover first and then open the front cover.

  • Make sure you are appropriately grounded using proper anti-static procedures.

Installing the printhead
Installing the Printhead Printhead Assembly.

  • 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).

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

  • 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.

  • Disengage Main Drive Belt from the three pulleys. below it, firmly grip board on both sides and pull it upward, carefully rocking it side to side in order to loosen it.

  • 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.


Stripe 400

  • 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.
