Image transfer unit (ITU) removal
See “Image transfer unit (ITU) assembly” on page 7-5 for the part number.
1. Write down the number of 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 assembly. See “Right cover assembly removal” on page 4-12.
3. Remove the waste toner bottle. See “Waste toner bottle removal” on page 4-81.
4. Remove the imaging unit (IU). See “Imaging unit (IU) removal” on page 4-49.
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 “Removal of ITU without the spring
clamp kit” on page 4-45. If the spring clamp kit is not installed, skip to “Continuing the removal (with or
without the spring clamp kit)” on page 4-46.
