Troubleshooting
1-56 HP Designjet T Series — Service Manual
If the front panel displays the message “Reseat” or “Replace” next to the
offending printhead, try cleaning the flex circuits of the Carriage and the
Printheads using the Carriage Interconnect Wiper.
Do not touch, wipe or attempt to clean the printhead
nozzles. This can damage the printhead and reduce print
quality.
