Setup and Installation

This section outlines the general steps for replacing the head lift linkage assembly. Specific steps may vary based on the PM4 model. Always consult the printer's service manual for detailed instructions.

1. Preparation: Power off the PM4 printer and disconnect the power cord. Open the printer cover to access the printhead assembly area.
2. Locate Existing Assembly: Identify the current head lift linkage assembly. Note its orientation and how it connects to the printhead and the printer frame.
3. Remove Old Assembly: Carefully detach any springs, pins, or screws securing the old linkage assembly. Keep track of all fasteners for reinstallation.
4. Install New Assembly: Position the new Intermec 1-206106-95 Head Lift Linkage Assembly in the correct orientation. Secure it using the previously removed fasteners. Ensure all connections are firm but do not overtighten.
5. Verify Movement: Gently test the printhead lift mechanism to ensure smooth and unobstructed movement. The linkage should operate freely without binding.
6. Close and Test: Close the printer cover, reconnect the power cord, and power on the printer. Perform a test print to confirm proper operation of the printhead lift function.

Operating Principles

The Head Lift Linkage Assembly is a mechanical component responsible for raising and lowering the printhead within the PM4 series printer. This action is crucial for:

• Media Loading: Allowing easy insertion and removal of labels or ribbons.
• Maintenance: Providing access for cleaning the printhead or platen roller.
• Error Recovery: Facilitating the clearing of media jams.

When the printer's cover is opened, or a specific mechanism is engaged, the linkage assembly articulates to lift the printhead, creating a gap for media handling. When the cover is closed, the linkage lowers the printhead into its operational position, ensuring proper contact with the media for printing.

Maintenance

Regular maintenance ensures the longevity and proper function of the Head Lift Linkage Assembly:

• Cleaning: Periodically inspect the linkage for dust, debris, or label adhesive residue. Clean with a soft, lint-free cloth. Avoid using harsh chemicals.
• Lubrication: Moving parts may benefit from a small amount of printer-safe lubricant if recommended by the main device's service manual. Do not over-lubricate.
• Inspection: Check for any signs of wear, bending, or damage to the linkage components, springs, or pivot points. Replace the assembly if significant wear or damage is observed.

Troubleshooting

If you experience issues related to the printhead lift mechanism, consider the following:

• Printhead Not Lifting/Lowering:
  • Check for obstructions (e.g., jammed media, foreign objects) preventing movement.
  • Inspect the linkage for bent or broken parts.
  • Ensure all springs are correctly attached and providing tension.
• Loose or Wobbly Printhead:
  • Verify that all screws and fasteners securing the linkage are tight.
  • Check for excessive wear in pivot points that might cause play.

If issues persist after basic troubleshooting, consult a qualified service technician or the main device's service manual.
