How to Replace a Printhead

Replacing a printhead is a careful job, not a hard one — most failures come from skipping preparation or reusing worn parts. This is the safe general sequence. Always follow your printer manual, and confirm the correct head version before ordering.

Before you start

• Power the printer off and discharge static (touch a grounded surface).
• Confirm the exact head version and part number for your printer. See the compatibility guide.
• Have new dampers, cap top and head cables ready — never fit a new head to old, dirty parts.

Installation sequence

• Remove the old head and note how the cables and ink lines were routed.
• Fit the new dampers to the head, then seat the head in the carriage.
• Connect the head cables carefully — they are keyed, do not force them.
• Prime the ink lines and run the printer's fill/purge cycle.
• Run a nozzle check and a test print to confirm all nozzles fire.

What most people get wrong

• Reusing old dampers or a dirty cap top — this re-clogs the new head quickly. Order them together.
• Forcing cables or connectors — bent pins ruin a head instantly.
• Installing before confirming the version — a mismatched head can be damaged on first fire.
