Regular maintenance guide CAUTION The printer has an internal clock which allows it to automatically wash the printheads and flush 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 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 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 Storage or Cleaning Kit to recover or protect the printheads. Automatic maintenance and cleaning will not be performed if you turn off the printer on the front panel. The printer power switch on the rear of the printer should only be used when the printer is turned off to move it, to connect it to a computer, or to install or maintain printer parts. Before starting the ink system storage procedure, make sure you have available the HP 780 Ink System Storage Kit and an empty waste ink bottle. Ink system storage This procedure allows you to empty the ink system of ink and fills it with storage liquid that will preserve the ink system if you do not intend to use the printer for a period of time (between two weeks and a month). CAUTION Do not open or close the covers or change the position of levers while the ink system storage process is being performed or the operation may have to be restarted from the beginning.
