Tell me about printhead cleaners
Each printhead has its own printhead cleaner, so there are eight printhead cleaners in
the printer. Printhead cleaners are used to clean and maintain the printheads, to
ensure the best possible print quality, and to seal the printheads when they are not in
use to prevent them from drying out.
Caution Whenever you buy a new printhead, you get a new printhead
cleaner with it. When you replace a printhead, always replace the printhead
cleaner at the same time. Leaving the old printhead cleaner in the printer will
shorten the new printhead's life and possibly damage the printer.
Tell me about ink system tips
For best results, always follow these guidelines:
●
Install the ink cartridges, printheads, and printhead cleaners before the install-by
date, which is printed on the packaging.
● Install a new printhead cleaner every time you install a new printhead.
● Follow the instructions on the front panel during installation.
● Allow the printer and printhead cleaners to clean the printheads automatically.
● Avoid unnecessary removal of the ink cartridges and printheads.
● The ink cartridges should never be removed while the printer is printing. They
should be removed only when the printer is ready for you to replace them. The
front panel will guide you through the removal and installation procedures (or see
“How do I remove an ink cartridge?” on page 99 and “How do I insert an ink
cartridge?” on page 104).
