Image transfer unit (ITU) removal
1. Write down the number on the new ITU before installing it. You will need the 16-digit numeric value from
the barcode after the installation, and it is easier to see at this point.
2. Remove the right cover. See “Right cover removal” on page 4-7.
3. Remove the rear shield. See “Rear shield removal” on page 4-7.
4. Remove the waste toner bottle. See “Waste toner bottle removal” on page 4-73.
5. Remove the imaging unit (IU). See “Imaging unit (IU) removal” on page 4-63.
Note: The ITU FRU includes a spring clamp kit. If the printer does not have this kit installed, perform the
following steps to prepare for the later installation. Continue below with “ITU without spring clamp
kit removal” on page 4-43. If the spring clamp kit is not installed, skip to “Continuing the removal
(with or without spring clamp kit)” on page 4-45.
ITU without spring clamp kit removal
1.
Pull the gear (A) straight out to unsnap it, and then discard it. A new gear is included in the spring clamp kit
and must be used with the new spring clamp.
