HP Designjet 4000 Printer Series - User Guide

Included with your printer (in the Maintenance Kit box) is a carriage interconnect wiper.
This should be used for cleaning the electrical interconnects of both the printhead
carriage and the printhead, which should be done if the front panel persistently
displays the Reseat or Replace message next to the printhead.
1. Remove a new pre-moistened replacement sponge from its pouch.
A supply of sponges is included in the box with the wiper. If all sponges have
been used, more can be obtained by contacting your customer service
representative.
2. Open the carriage interconnect wiper.
