Replace an ink cartridge
CAUTION
Always use Genuine HP Ink Cartridges. These have been designed for high-quality
imaging performance and reliable printer operation. Using non-HP inks may cause poor print
quality, printer malfunction, prin ter failure, or a safety hazard. The hazard characteristics of
different solvent inks can vary widely. HP has not conducted product safety testing for non-HP
inks with this printer and is not responsible for  any loss or damage that may result if non-HP inks
are used.
HP Ink Cartridges should be installed before the  “Install By” date printed on the cartridge. Use of
the Ink Cartridge 3 months beyond  the “Install By” date may cause deterioration in print quality
or a printer malfunction.
NOTE If an ink cartridge cannot be inserted, check t hat the color matches the slot. A mechanical
key prevents an ink cartridge from being inserted into the wrong slot.
Do not shake ink cartridges before inserting into the printer.
The front panel will advise you when  you need to change an ink cartridge.

WARNING!Never switch off the printer without following the correct procedures. Even with the

make sure you observe the appro priate maintenance guidelines.
ENWW Regular maintenance guide 67
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 printheads, whic h keeps the printheads in good condition. The
printer automatically washes  the printheads regularly after the la st 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 eith er 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 high-quality
imaging performance and reliable printer operati on. Using non-HP supplies may cause poor print
quality, printer malfunction, printer failure, or a safety hazard.

Daily maintenance
WARNING!Failure to perform daily maintenance pr ocedures may result in damage to your
printheads and will invalidate your warranty.
CAUTION If you need to leave the printer unat tended for any reason, ensure that the printer
is on , the ink cartridges are full , the waste ink bottle is empty , and media is loaded  so that
automatic maintenance (performed regularly after  the last printing process) can be completed
successfully for the time you  are not present. If needed, inst all new ink cartridges. The ink
cartridges that you replace can be  reused when you return to your printer, if they still contain ink.
The ink cartridges must be stored properly and should not be used again if 3 months passed the
install by date (on the product label).
Daily printhead maintenance will ensure optimal print quality and the life of your printheads. The ink in your
HP Designjet 8000s 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.
When the following message is displayed, imme diately perform daily maintenance procedures:
●Clean the capping unit.
● Check the wiper liquid level.
● Check the waste ink bottle level
● Perform Normal printhead cleaning
● Print the NOZZLE PRINT pattern
NOTE
Perform the above every day before printing.
Always use the specified cleani ng liquid and cleaning equipment.
