CAUTION If you need to leave the printer unattended for any reason, ensure that the printer is on, the ink cartridges are full, and the waste ink bottle is empty, so that automatic maintenance (performed after the first 20 hours without printing and every 3 days) can be completed successfully for the time you are not present. If needed, install new ink cartridges. The ink cartridges that you replace can be reused when you return to your printer, if they still contain ink.

Daily printhead maintenance will ensure optimal print quality and the life of your printheads. The ink in your HP Designjet 9000s Printer dries very quickly, so maintenance procedures ensure that the ink does not dry in the capping unit, the wiper blades, the ink tubes and printheads.
