Printhead

Printhead failed

Leads to repair-vs-replace, which is the highest-value decision page.

Likely causes and fixes

  1. 1. On Epson EcoTank and most consumer inkjets the printhead is integrated and not user-replaceable; if the nozzle check still shows gaps after Power Cleaning, a rest period, and Power Ink Flushing, Epson's own escalation path is to contact Epson rather than swap the head.

    1. Caution: Power Cleaning uses a substantial amount of ink.

      Run Power Cleaning from the printer's ink menu.

    2. Print a nozzle check; if gaps remain, power off and let the printer rest for at least 12 hours.

    3. Caution: This step can be done wrong in a way that is costly or hard to undo, including voiding your warranty. Check your model's manual before proceeding.

      Run Power Ink Flushing, then recheck nozzles after another 12-hour rest.

    4. If gaps persist, contact Epson support — the printhead is not a user-replaceable part on these models.

  2. 2. On some HP inkjets the printhead carriage has no release latch, meaning the printhead cannot be swapped by the user or ordered as a routine part — a failed printhead there requires a paid HP repair or full replacement.

    1. Power-cycle the printer: turn it off, unplug for 60 seconds, plug directly into a wall outlet, and power on.

    2. Caution: Work carefully around the ink cartridges.

      Open the ink-cartridge access door and check whether the carriage has a printhead latch.

    3. If there is no latch, the printhead is not user-replaceable — contact HP support for repair or replacement.

    4. Caution: This step can be done wrong in a way that is costly or hard to undo, including voiding your warranty. Check your model's manual before proceeding.

      If a latch is present, order the correct printhead part number through HP and install it following HP's model-specific replacement guide.
