CAUTION The printer has an internal clock which allows it to wash the printheads automatically, flushing some ink through the printheads, which keeps the printheads in good condition. The printer automatically washes the printheads regularly after the last printing process. If the printer is switched off or media is not loaded, 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 printheads will fail. If the printer must be switched off for a long period of time, the customer must use either the optional HP Ink System Cleaning Kit or HP 780 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 with media loaded. 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.
CAUTION The use of safety glasses and gloves is recommended when performing cleaning and maintenance operations.
Always use genuine HP cleaning kits. These have been designed for maintaining
