Part numbers and an exploded view of the pickup
assembly. The pickup foot (part number RB2-2891-000CN) is available from
http://www.hp.com. As of October 2003, the

First, remove the toner, paper cassette and
power / interface cables, then set the printer up on its back.
Locate the paper pickup foot in the center near the front of the printer.
It is the dark rubber curve between the two white plastic rollers in the
picture.
Notice that its shaft runs through two "bushings"
where it passes through the supports on either side.

On the left side, gently pull the arm on the
bushing out a little bit from the support and rotate it toward you.
this is much easier to see on the pictures of the right bushing below
because that one is white and this one is black.
Continue to move the arm up while pulling it
gently to the left. When the bushing reaches the correct position, it will
move to the left, sliding out from between the support and the shaft.
Remove the left hand bushing.
On the right side, again, find the arm on the
bushing.
Gently pull the arm on the bushing out away
from the support and rotate it toward you.
Continue raising the arm while gently pulling
right until the bushing slides to the right. It will not move all the way
from between the shaft and the support.
Take care that the black paper sensor just to the right of the bushing is
not moved out of position.
Now rotate the arm down and completely back
into the body of the printer.
The right bushing can now be moved to the right
just a little more. This is absolutly necessary.
Grasping the left end of the shaft and the
right wheel as shown, push it to the left while holding the right bushing
to the right.
On the left side, there is a small bit of metal
behind the left side wheel which will stop the unit from moveing all the
way to the left. pull the shaft forward, away from the printer, to clear
this obstruction and move the unit all the way to the left. Again, this
is absolutly necessary.
Pull firmly with your thumb and the right end
of the shaft should just clear the right bushing. If not, review the steps
above paying special attention to those comments in italics.
Continue to pull the right end of the shaft
out, makeing shure that the right bushing stays in place then slide the left
side out.
The pickup foot wheels are easy to pull off
the shaft.
With a firm pressure, work your thumb under
the rubber material.
Useing both hands, peel the rubber back.
Continue to pull the rubber off the foot.
Now that the rubber is removed, it can be replaced
or cleaned, rughed up and re-installed
If you will re-use this rubber, flip it back
right side out.
The surface can be cleaned with rubbing alcohol
and should be roughed up with course sandpaper or a wire brush.
Start the new or re-furbished rubber back onto
the foot.
Make sure that the best surface is alligned
with the flat spot on the foot.
Work the rubber back on.
Use your fingernail to push down the rubber around both sides so that it
is off the slight lip that edges the
foot.
Reinstall the wheels.
Orient the foot so that the flat spot is towards
you.
Insert the left end of the shaft.
Pull the left end of the shaft towards you
so that the assembly will move as far left as possible.
While holding the right bushing to the right,
align the right edge of the shaft with the bushing.
Push firmly back.
Push the shaft to the right, rocking the foot
as needed to line up the shaft with the drive key on the right.
While holding the shaft to the right, move
the right bushing to the left.
Rotate the right bushing arm up until the bushing
is able to move further left.
Keep moveing it up until the bushing slips
all the way to the left.
Push the arm back down until it contacts the
support and then locks into place.
Line up the left bushing with the arm to the
left and push it over the shaft.
Wiggle the shaft and bushing until the bushing
slides between the shaft and the support.
Push the arm
down.
and lock it into
place
Ensure that the paper sensor is unmoved and
still able to rock up and down freely.
