Inserting a CCU
To insert a CCU, follow these steps.
1. Open the top cover of the cart containing the new color CCU.
NOTE: CCUs are not interchangeable between printer
models. Make sure you order and use the one designed for
your printer.
2. Push the cart up to the printer, lining up the gold knob on the
cart with the gold recess on the printer inner cover.
3. Push the cart firmly against the printer until you can feel the
two latch together.
4. Push down firmly on the cart pedal until you hear or feel the
pedal catch. The pedal should stay locked down. The pallet
containing the CCU is raised.
5. Using the CCU handle, firmly push the CCU into the printer.
6. Turn the gold CCU handle counterclockwise for a quarter
turn. If it does not turn, check that the CCU is firmly seated in
the printer.
7. Turn the backup roller handle counterclockwise for a quarter
turn.
