printheads

If you experience print quality issues that cannot be resolved by cleaning
your printheads and you have verified that the printheads need to be
replaced, you may need to replace them. You may also see front-panel
display messages that indicate when individual printheads need to be
replaced.

See the Support and Specifications booklet for information on ordering
replacement printheads.

Turn on the unit, then open the print-carriage access door by lifting the

The print carriage moves to the center of the unit.

latch and then lift the print carriage to access the printheads.
