remove the printheads indicated.
Look at the electrical contacts on the printhead and carriage. If they are
dirty, they should be cleaned.

damage the printhead. Handle the ink systems with care.

system error”.
Printhead failure
JJ-J →
The printheads indicated by flashing squares have failed, either during printhead
initialization or during printing. The printer may have detected an unusual
electrical or thermal signal from the printhead that may require attention. The
most likely causes of this message are:
D The ink cartridge is empty. If this is so, your ink system has reached the
end of its normal life, and you will need to buy a new ink system to
replace the old one.
D There has been a problem inside the printhead that has caused it to fail, for
example, the printhead has overheated.
You should replace the indicated ink systems immediately.
Press the
↓
key to check the printheads. Open the window when indicated, and
remove the printheads indicated. Try reseating the printhead.
If you don’t correct the error now, you will see the status message “Ink
system error”.
