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 76, 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 89.
