							CAUTIONThe 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 3 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 Ink System Cleaning Kit or
the HP 790 Storage Kit to recover or protect the printheads.
Automatic maintenance and cleaning will not be performed even if you turn off the printer at
the front panel. The printer power switch at the rear of the printer should be used only when
the printer is turned off to move it, to connect it to a computer, or to install or maintain printer
parts.
Have available the HP 790 Ink System Storage Kit. Six ink system storage liquid cartridges and six ink
system purging cartridges are packed together in the storage kit.
Have available 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 (two to four weeks).
CAUTIONDo not open or close the rear 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. This will result in the waste of the storage liquid. If ink system storage has to be
restarted, new storage liquid cartridges will be needed.
