User cleaning
Schedule of tasks
The parts and supplies required for these procedures may be purchased as a kit (HP product number
CQ121A). Consistent and proper use of this kit will contribute to optimal printer performance, extend
lamp and printhead life, reduce the number of service calls, increase image quality, and reduce the
potential for output artifacts.
Follow the cleaning schedule or clean as needed (depending on frequency of use and amount of dust
and airflow around the printer). The printer displays maintenance reminders on the control panel
according to this schedule or actual in-service time, as appropriate. You can display the service
intervals and actual elapsed printing time for each task from the control panel menu (System Page >
Tools > User Cleaning and Maintenance > Maintenance Reminders).
To perform these procedures, follow the instructions in this chapter or on the control panel under
System Page > Tools > User Cleaning and Maintenance.
