changing pick-up roller CLP-300

A) PREPARATIONS
1. turn off and remove power cable
2. remove paper drawer
3.
remove imaging unit: I don't think this is necessary, what I would
remove is the toner waste cartridge (open the front panel, and pull out
the L-shaped object on the left side), because you don't want toner
spilling all over the place.
4. turn the printer upside down. for these instructions, have the front of the printer face you.

B) ACCESSING THE ROLLER
5.
Look at the axle where the pick-up roller is attached to. There are two
white plastic things at the ends. The left end has a tiny plastic tab
protruding along the axis of the axle. It's basically L-shaped, and the
axle has a small hole where the L sits inside.
- So use a small flat
screwdriver to gently pry up this tab. I would slide a stuff piece of
paper (manilla folder or business card) underneath so you are not
over-flexing and snapping this tab. After you have the piece of paper
all the way through, just leave it there.

6. Slide the locker
towards the center (to the right). It will slide about 0.5 inches; don't
force it too much. The purpose of this maneuver is it will allow you to
rotate the entire axle in order to gain full access to the roller.
7.
Rotating the axle: this will require a little bit of playing around,
but should not require excessive force. I found it most effective to
rotate so the *top* is rotating towards you and not away from you. Just
jiggle the axle around; I held it at the central rubber thing and shook
it around to rotate it.
8. The rubber belt is attached to a plastic
shell. The plastic shell is attached to another plastic shell around the
axle. You'll find two flexible tabs that lock the plastic shells
together. You want to have this positioned towards the bottom because
you need room to access the entire rubber belt.
9. The other side of
the rubber belt (opposite the tabs) is somewhat locked into the plastic
shell, so you have to use some force to lift it away. After that,
everything should be free.
10. Washed with water, dried it out. You
don't want to turn the belt inside out. What I did was remove the belt,
and since it was a symmetrical shape, I just flipped it over, so the old
surface is switching places with a new surface.
11. Push the plastic
shell back in with the small protrusions first, then you can push the
entire thing to have it lock into the plastic tabs. Now you will rotate
the axle away from you (which should be easier), and position everything
like at the beginning. Remove the piece of paper at the plastic tab,
and then hold onto the axle and push the left plastic locker to its old
position. Replace the toner waste cartridge and test everything out.
