Replacing the Photo Conductor Unit

The following procedure describes replacing the first photo conductor unit from the right. The procedure is the same for all four photo conductor units.

When to replace the photo conductor unit

Replace the photo conductor unit if any of the following messages appear on the display:

"Replace PCU:Black."
Replace the black photo conductor unit.
"Replace PCU:Colour."
Replace the three color photo conductor units.
The color photo conductor units (yellow, cyan, and magenta) are supplied as a single item.

Exposure to light reduces photo conductor unit performance. Replace the unit as quickly as possible.
Do not pull out the photo conductor unit quickly or with force as it may fall.
Take care that nothing comes into contact with the top surface of the photo conductor unit.
When holding the photo conductor unit, grab the green grip on the left and the handle on the front together. Do not move the photo conductor unit by only grabbing the grip. Doing so may damage the grip.
Place no objects on the front or inner cover.

Turn off the power, and then unplug the power cable.
Carefully open the left cover.
Turn the two green levers counterclockwise (), and then slowly open the inner cover ().
The photo conductor units are installed as shown. From the right, the units are attached in the order of black (K), magenta (M), cyan (C), and yellow (Y).
Remove the photo conductor unit you want to replace. Turn the green lever counterclockwise to unlock the unit. (The black photo conductor unit is used in this example.)
Pull out the ring pull handle of the photo conductor unit.
Hook your finger through the ring pull handle, and then slowly pull out the photo conductor unit. When you have pulled the unit half way out, support the photo conductor unit using your other hand, and then pull the unit completely out.
