Carriage interconnect wiper
When you replace the printhead, check the empty slots to see whether they
need cleaning. In some 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 printer is a carriage interconnect wiper. This should be
used for cleaning the electrical interconnects of both the printhead carriage
and the printhead.
This procedure should be performed every time you replace a printhead.
If the front panel persistently displays the message “Reseat” next to the
printhead, try performing the procedure shown here.
NOTE: After waiting a few moments to allow both connectors to dry,
replace the printhead into the carriage assembly. Use the procedures in 73,
in section maintain the ink system on the reverse of this guide.
NOTE: Do not touch, wipe, or attempt to clean the printhead nozzles. This
can damage the printhead and reduce print quality.
1 To clean the carriage electrical interconnect, remove a new pre-moistened
replacement sponge from its pouch. A supply of sponges is included in the
box with the tool. If all sponges have been used, more can be obtained by
contacting your customer service representative.
2 Open the carriage interconnect wiper.
