Inks
5-3
If there is still dry ink in the bottle, the ink may spill as you move
the bottle back onto its lid.
4. Remove the empty bottle and discard it.
5. Shake the new ink bottle at least ten rotations, taking care to
support the bottle cap. It is important that you mix the
contents thoroughly by allowing the material inside the bottle
to fall and settle toward the cap at each rotation.
NOTE: Both black and colored dry ink contain a mixture of
toner and developer material. This mixture may have settled
during shipping, and the bottle must be agitated before you
install it in the printer to ensure the dry ink is dispensed
properly. Unmixed dry ink causes print quality problems that
the printer will attempt to correct through excessive dead
cycling. Unmixed dry ink could also result in damage to some
machine parts.
6. Insert the new bottle into the printer until it is latched into
place. The cap will remain in the front of the compartment as
you push the bottle toward the back.
