HP Designjet 9000s Printer series - Manual (Page 77)

CAUTION If 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
NOTE Perform the above every day before printing.
Always use the specified cleaning liquid and HP cleaning swabs.
Wiper blade cleaning
CAUTION Make 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.
