5. Using the same cloth, clean the strip of electrical contacts on the printhead (unless the printhead is
new). Avoid touching the printhead nozzles.
CAUTION: Do not touch the surface of the printhead that contains the nozzles, because the nozzles
are easily damaged.
6. After waiting a few moments to allow both connectors to dry, replace the printhead into the printhead
carriage. See
Insert a printhead on page 65.
7. Wash or dispose of the cloth. Take care to prevent the transfer of ink onto hands and clothing.
If the front panel continues to show the Reseat or Replace message, replace the printhead or contact your
HP customer service representative.
Clean the printhead drop detector
The printhead drop detector is a sensor that detects which nozzles on the printheads are not printing, so that
other nozzles can substitute for them. If particles block the sensor (such as fibers, hair or small pieces of
paper), print quality is affected.
When the front panel displays a warning message that the drop detector needs cleaning, you are
recommended to clean it. If you do not clean it immediately, the printer continues working normally, but the
front panel display continues to show the warning.
CAUTION: Wear gloves to avoid getting ink on your hands.
