How do I maintain the printer? CAUTION The printer has an internal clock which allows it to wash the printheads automatically, flushing some ink through the printhead, which keeps the printheads in good condition. This is done after the first 20 hours without printing and every three days. If the printer is switched off for a long period, this process does not happen. If the ink does not flow through the printheads from time to time, the ink will dry inside the nozzles, reaching a point where it is impossible to recover them and the printhead will fail. If the printer must be switched off for a long period of time, the customer must use either the optional HP 790 Ink System Cleaning Kit or HP 790 Ink System Storage Kit to recover or protect the printheads. Automatic maintenance and cleaning will ONLY be performed when the printer is switched on and powered up. If you switch it off on the front panel or with the power switch on the rear of the printer this maintenance will NOT be performed.

Failure to perform daily maintenance procedures may result in damage to your printer printheads and will invalidate your warranty. 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 that is performed after the first 20 hours without printing and every three 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. 190 Chapter 6 How do I maintain the printer? ENWW
