Manual printhead cleaning procedure for HP Latex 110, 300 and 500 Printer Series

HP-ALBA 16th of April 2020

Manual printhead cleaning procedure


1. Place the printhead on a flat surface with the nozzles facing upwards.

2. Place enough distilled water (2 or 3 drops, being careful with the electronics) to cover the nozzles completely and allow some time for the water to soften the ink.


IMPORTANT: Use only distilled water as regular water can damage the printhead.


IMPORTANT: Make sure not to pour any water on the electrical contacts or any other part of the printhead apart from the nozzles since it could damage the printhead irreversibly.



3. Very gently wipe the printhead twice against the lint-free microfiber cloth, on a flat surface, in the direction shown.



IMPORTANT: Be very gentle with the nozzle’s contact with the lint-free microfiber cloth. Otherwise it could damage the printhead irreversibly.


IMPORTANT: Be careful not to wipe a printhead against an area where Optimizer ink may be present. Otherwise it could damage the printhead irreversibly.
