HP Designjet 9000s Printer Series - Printhead Nozzle Plate Cleaning Sheets

Introduction

Printhead nozzle plate cleaning sheet is now available as a new service part. The Printhead cleaning sheet, Q6665-60089, is provided to remove dried ink and dust from the printhead nozzles. We recommend that all users clean the printhead nozzles plate once a month in order to keep the nozzles healthy. This is especially important for customers that frequently print long jobs.

Instructions for using the kit

  1. At the heater control panel turn Off:
    • Front heater
    • Print heater
    • Rear heater
    Check that the front paper guide, platen and rear paper guide have cooled down to at least 30°degree Celsius or below. If not, wait until they cool down.
    note:
    Make sure that the platen and paper guides are sufficiently cool before cleaning the printheads. Otherwise, especially if the platen is still hot, the wiper cleaning liquid will evaporate quickly, causing insufficient cleaning, or the nozzle plate and printhead cleaning sheet will stick to each other. They may cause a printer malfunction.
  2. On the front panel, go to the Printhead maintenance menu, and select CAP CLEANING to move the carriage to the wiper side.
  3. Lift the media load lever to release the media grip, and pull out the media.

  7. Apply 4 cc of the wiper cleaning liquid to the cleaning surface (white surface) of the printhead cleaning sheet with a syringe provided in the regular maintenance kit.
