One of the following might have occurred.
— Both printheads are missing.
— Both printheads are installed incorrectly.
— Both printheads still have orange plastic tapes or plugs
on them.
— Both printheads are incompatible or damaged.
— If there are no printheads installed in the printer, install
the printheads.
— If both printheads are installed in the printer, remove the
printheads, make sure there is no plug or plastic tape on
them, and then reinsert the printheads securely.
CAUTION: These instructions only apply when you
install pritheads during initial printer setup. If the
printheads have been primed with ink, you must not

for your printer.
