Here you go. It really isn't difficult.

first off you want to remove both side covers, there is one screw on the
top back of the covers, and another on both covers, top front, you have
to open the front paper path door to access the front screws. Then
about the middle of the covers pull up and outward, they will kind of
pop off, but thats fine, they have tabs on the bottom that can be pesky.
Remove the paper tray, the green maintenance tray and set aside.
Now
remove the 2 green rails that the maintenance kit rides on. They both
are held in by one screw. It will take some manipulating to get them
out, but basically you push them slightly back, inward and twist
slightly until they come out. TAKE NOTE of how the leaf springs are on
the rails, A hint when putting them back in, is to take some scotch
tape and tape them on the side to keep them in place, You will see what
I mean when you remove them. But its much easier to get the rails back
in when those springs are taped to the side. And no worry about
removing the tape afterward, I will have no affect on the machine if
its left in.
Next, you look up and you will see a stainless steel
curved plate. About 10 inches long and 3 inches high. There are 2
screws on the top of it that must be removed. There are 2 tabs on
bottom, Once the screws are removed it just lifts out.
Now about
midway up the paper path is the registration rollers. First, you have
to go, ( looking from the front of the machine) to the left side of the
machine, You will see a electromechanical clutch on a shaft with a 2 inch
black gear with a belt attached. Remove the clip that holds the clutch
on, slide off the gear and just let the belt drop in place.
Now,
return to the front,The assembly is stainless steel, you will see a
couple of rollers on it and some paper path actuators. There is one
screw on the right side of that assembly that you need to remove, and
on the left side, just by the bearing there is an "E" clip holding the
bearing against the frame. remove the screw and the clip, Then move
that transport CAREFULLY to the left and out. Be very careful to keep
the 2 pieces together, there is a switch actuator that can be easily
broken. So please take caution. On the right side, there will be a
bearing that WILL fall out, and drop down into the paper feed area.
Trust me it will do that. Just locate it and pick it up. When replacing
that transport. I suggest, ( unless your considering suicide LOL) Put
some white out or a little glue on the outside of that bearing when you
press it back into the frame. Otherwise, IT WILL keep falling out and
really try your patience. Just trust me on that one.
Now, look in
the front , just above where the maintenance tray would go. You will
see 2 screws, about 10 inches apart, They will be surounded by a
beige/brownish plastic. Remove those 2 screws, they hold in the heater
assembly you want to repair. When you remove those screws it will not
yet come out, wiggle it a bit and look on the right side so you can
easily determine the conectors, plugs you need to remove. Some have 1
some have 2.
Once you do that, slide that heater assembly downward and out. You will see the 2 lamps in there.
Take
those little spring metal clips out,, replace BOTH lamps. Use some
emery cloth to clean the contacts. Clean the reflector behind those
lamps before replacing . That will make the heat transfer more
efficient.
Once those are in , in reverse order reassemble. Just be
cautious replacing that registration assembly so you don't break the
black actuator.
It's really not hard, just takes some time. Give
yourself an hour to an hour and a half. But that is your problem I
guarantee it.
