or
Printhead check
error
→
The message “Printhead check error” may be displayed if:
■ You are using colored media. Either disable checking or use media that is
clean, white, and opaque. See the remarks on 11-35, Media Problems.
■ There are dirty nozzles on the printhead. Replace your ink system (see page
11-38, Checking Ink Systems). Do not attempt to clean the nozzles.
The squares that are flashing indicate the ink systems that have failed. If the message
contains no squares, the procedure has failed because of a problem that is not related
to specific printheads, for example, a problem with the media.
Press
↓ to continue. The message “Check ink system→ / Ignore→” will be displayed.
If you press
↓ again to continue, you may still be able to print again, but image print
quality may be affected. To fix the problem, select
↑
to check the ink system; see 11-
38, Checking Ink Systems.
Printhead contact
error
■■❏■→
CAUTION:
The printheads, indicated by flashing squares , have failed to function because of an
unusual electrical signal from the printhead. The most likely cause of this
message is that the electrical contacts on the printhead or printer carriage are
dirty and need cleaning.
Press the
↓
key to check the printheads . Open the window when indicated, and
remove the printheads indicated.
Look at the electrical contacts on the printhead and carriage. If they are dirty,
they should be cleaned (see 11-42, Cleaning Electrical Contacts).
Do not touch, wipe, or attempt to clean the printhead nozzles. This can damage
the printhead. Handle the ink systems with care.
If you don’t correct the error now, you will see the status message “Ink system
error” described on page 12-6.
