  2. Examine the gold chip contacts for fingerprints or ink residue.
  3. Wipe the contacts gently using a clean eraser or a lint-free cloth.
  4. Re-insert the cartridge firmly until you hear the mechanical latch 'click' into position.

Maintenance and Prevention

Avoid touching the golden contact chips with your bare skin. Maintain a clean printing environment and ensure your ink bay area is free from excessive dried ink buildup.

When to Call a Technician
