Regular maintenance guide
The printer requires regular inspection and maintenance. The table below lists all regular inspection and
maintenance procedures. For details on each procedure, see the page reference.
WARNING! off the printer without following the correct procedures. Even with the storage
liquid installed, never leave the printer off for more than 4 weeks. Leaving your printer off for
more than 4 weeks can cause permanent damage that cannot be repaired. In all other cases
make sure you observe the appropriate maintenance guidelines.
ENWWRegular maintenance guide 65
How do I maintain the printer?
 
						

							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
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 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.

WARNING!Failure to perform daily maintenance procedures may result in damage to your
printer printheads and will invalidate your warranty.

							CAUTIONIf 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.
●Wiper blade cleaning
●Wiper sponge cleaning
●Capping unit cleaning
NOTEPerform the above every day before printing.
Always use the specified cleaning liquid and HP cleaning swabs.
Wiper blade cleaning
CAUTIONMake sure that the wiper cleaning liquid does not drip on to other parts of the
printer. If the wiper cleaning liquid drips on to the belt or any nearby sensors, this could cause
serious damage to the printer.

to clean the wiper blades. The capping liquid is not strong enough to clean the wiper
blades properly and could cause damage to the printheads.

Remove clothing soaked with ink from contact with skin.
Use an approved eye wash station if ink is splashed into eyes and consult a doctor if
necessary.
