Whenever you replace the printhead, check the
empty slots to see if the carriage interconnect needs
cleaning. In extreme cases it is possible that the
printer will not recognize a printhead when it has
been installed. This is due to the build-up of ink
deposits on the electrical connections between the
printhead and the printhead carriage.

Included with your HP Designjet printer, is a
Carriage Interconnect Wiper. This must be used for
cleaning the electrical interconnects of both the
printhead carriage and the printhead.

If the front-panel persistently displays the message
“Reseat” next to the printhead try performing the
procedure shown here.

NOTE: Do not touch, wipe or attempt to clean the printhead nozzles. This can damage the
printhead and reduce print quality.

NOTE: After waiting a few moments to allow both connectors to dry, replace the printhead into
the carriage assembly
