Step 1
With the handle of the cartridge facing you, remove two Phillips screws -
one from each side on the top of the cartridge.
Step 2
Using both hands, grab the top of the cartridge with the instruction label
on it. To remove it, pull the cartridge top up and back towards you. This is
the waste hopper section of the cartridge, and it may leak some toner as it
is removed. Turn the waste hopper over and place it on the table with the
label facing down.
Step 3
Place the toner hopper aside and protect it from light.
Step 4
Hold the waste hopper with the wiper blade facing you. Remove two
Phillips screws one from each side of the wiper blade. Lift the blade
straight up from the waste hopper and visually inspect it for damage.
Clean the blade with compressed air and a clean, lint-free cloth. Set the
blade aside.
Step 5
Clean the remaining waste toner from the waste hopper using a vacuum
or compressed air. Be careful not to damage the retaining blade in the
waste hopper opposite the wiper blade that was removed. Inspect the
retaining blade after cleaning to ensure that it is straight and not damaged.
Step 6
Pad the wiper blade that is to be installed with padding powder. Reinstall
the blade using two Phillips screws, one on each side of the blade. Place
the completed waste hopper aside.
Step 7
Set the toner hopper with the long handle towards your right and
remove two Phillips screws that are holding the end cap in place.
Using a small, flat-blade screwdriver, carefully pry off the end cap.
The end caps contain the drum axles.
Step 8
Rotate the cartridge so that the opposite end is facing you with the
handle of the cartridge to the left. Remove two Phillips screws that are
holding the end cap in place. Using a small, flat-blade screwdriver,
carefully pry off the end cap.
Step 9
Rotate the cartridge so that the handle of the cartridge is facing you.
Grasp the PCR shaft and slide it towards your left to remove it from
the right PCR saddle. To remove the PCR from the left PCR saddle, lift
the PCR up on the right side to clear movement and move towards the
right to remove the PCR.
Step 10
Remove the drum by pushing up on the helical gear with your finger
enough to grab the entire gear. Pull the drum away slightly from the
opposite side and lift it completely out. Set the drum aside in a protective
area.
Step 11
Rotate the cartridge so that the handle is facing towards your left and
remove the fill plug from the end cap. Clean out all remaining toner from
the inside of the toner hopper. Place the fill plug aside until later.
Step 12
On the cartridge end that contains the fill plug and electrical contacts,
push up the wire that contacts the developer roller shaft. Release the clip
that holds the black contact support plate by pushing the tab in from the
outside of the cartridge. Gently pull forward on the plate to remove.
Step 13
Remove the developer roller drive gear from the developer roller using a
small, flat-blade screwdriver to push with. The center idle gear in the gear
train is loose and can fall off, so remove it and place it aside. The smaller
helical diameter teeth face inward.
Step 14
Remove the developer roller by holding the metal shaft on either end and
pulling upward.
Step 15
Start by placing the cartridge with the cartridge handle facing you and
the handle extended outward. Remove two Phillips screws, one from each
side of the doctor bar. Carefully lift up the doctor bar from the left side
just enough to clear the location pin. Holding the doctor bar steady, work
towards the right and lift straight up off the locator pin and back towards
you. This will allow the electrical contact wire to rest in the tab slot of the
cartridge. Clean with 99-percent Isopropyl alcohol and a lint-free cloth.
Step 16
Clean the toner hopper area, which includes the toner feed roller, developer
roller recovery blade, sealing felts, PCR saddles and toner tank area.
Be very careful not to damage these parts by using too strong an air flow.
Step 17
Place the cartridge with the cartridge handle facing you and the handle
extended outward. To install the doctor bar, on the right side push the
electrical contact wire forward and to the right to rest just out of the way.
Install the blade by lining up the location pins on each side and coming
straight down. Hold in place by inserting the two Phillips screws, one on
each side of the doctor bar. Move the electrical contact wire back into
position.
Step 18
Holding the developer by the shaft on each side, position and install the
developer roller. Push down with just a little pressure to set and replace
the developer roller idle and drive gear.
Step 19
Moving to the electrical contact end of the cartridge, push the electrical
contact wire up out of the way and replace the black contact support plate
by pushing the contact support plate in until it latches. Bring the electrical
contact wire down and in contact with the metal shaft end of the
developer roller.
Step 20
Fill the toner into the toner hopper and replace the fill plug.
Step 21
Place the cartridge with the cartridge handle facing you and the handle
extended outward. Place the drum into the cartridge with the helical gear
to your right.
Step 22
With the longer shaft of the PCR on your left side, install the shaft into the
left side PCR saddle enough so that you can clear the right side of the cartridge.
Pull the right side saddle up enough so that you can push the PCR
towards your right and into the saddle until it stops. Place a little conductive
grease on the contact of the PCR saddle before installing it.
Step 23
Place the toner hopper with the long handle towards your right and install
the end cap and the two Phillips screws to hold the end cap in place.
Step 24
Rotate the cartridge so that the opposite end is facing you with the handle
of the cartridge to the left. Install the end cap and the two Phillips
screws to hold the end cap in place. Place a little conductive grease on the
contacts as applicable.
Step 25
Place the cartridge with the cartridge handle facing you and the handle
extended outward. Holding the waste hopper with the label up and
embossed arrows pointing away from you, place the tabs on each side into
the slots and tilt forward. Hold in place using Phillips screws, one on each
side.
Step 26
Replace the fuse. The fuse is located on the right side of the cartridge with
the cartridge handle facing away from you. The fuse is blown when
installed into the printer to reset the counter/flag.
