Troubleshooting
Solving Ink System Problems
11-39
CAUTION Do not touch, wipe, or attempt to clean the printhead nozzles. This can damage the
printhead. Handle the ink systems with care. (See the diagram on page 11-42.)
n Make sure that the protective blue tape and green cardboard have been removed
from the printhead.
n Next, look at the electrical contacts on the side of the printhead and on the carriage.
If they are dirty, they should be cleaned (see page 11-42, Cleaning Electrical
Contacts).
n Reinsert the printhead. In some cases, if you repeatedly get an error, with the
squares continuing to flash, you may need to remove and reinstall all printheads to
clear it. See If You Have Problems Reseating a Printhead on page 11-41.
Repeat these steps for any other printheads that need replacing.
Close the window.
Checking the Printhead Cleaners
If prompted, open the right door to access the printhead cleaners.
The message “Check / Close right door” is displayed. The stars in the
message indicate which printhead cleaners must be checked.
n For each printhead cleaner, make sure that it is not overflowing (liquid all the way
to the top of the large rectangular hole).
n Check that the part number on the printhead cleaner matches the type of ink system
you are using. (The printhead, cleaner and ink cartridge must all be of the same
type.) For Imaging Ink Systems the part numbers are C1806A to C1809A, and for
UV Pigmented Ink Systems they are C1892A to C1895A.
n Check that the black and white label next to the large rectangular hole has not been
completely obscured by ink spray (some spray is normal). If it is, the printer may
not be able to detect the printhead cleaner and will report a Head Cleaner Removed
message. You will need to replace the entire ink system (printhead, printhead
cleaner and the ink cartridge) if this is the case.
n Reinsert the printhead cleaner. Make sure it snaps into place properly.
Repeat these steps for any other printhead cleaners that need replacing.
