HP Officejet 7110 Wide Format ePrinter - H812a - Manual (Page 69)

CAUTION: While ink cartridges are not damaged when left outside of the printer, the printhead does
need to have all cartridges installed at all times after the printer is set up and in use. Leaving one or
more cartridge slots empty for an extended period may lead to print quality problems and possibly
damage the printhead. If you have recently left a cartridge out of the printer for an extended period, or
if you have had a recent paper jam, and have noticed poor print quality, clean the printhead. For more
information, see Clean the printhead on page 86.

The printer is making some unexpected noises
You might hear some unexpected noises made by the printer. These are the servicing sounds when
the printer performs automatic servicing functions to maintain the health of the printheads.
NOTE: To prevent any potential damage to your printer:
Do not turn off the printer while the printer is performing any servicing. If you are turning off the
printer, wait for the printer to come to a complete stop before turning it off using the (Power)
button. For more information, see Turn the printer off on page 14.
Make sure all ink cartridges are installed. If any of the ink cartridges are missing, the printer will
perform extra servicing to protect the printheads.
Blank or partial page printed
Clean the printhead
● Complete the printhead cleaning procedure. For more information, see Clean the printhead
on page 86. The printhead may need to be cleaned if the printer was turned off incorrectly.
NOTE: Incorrectly turning off the printer can cause print quality problems like blank or partial
pages. Printhead cleaning can solve these problems, but turning off the printer correctly can
prevent them in the first place. Always turn the printer off by pressing the (Power) button on
the printer. Wait until the power light goes out before unplugging the power cord or turning off
a power strip.
