Remove Cartridge Hold Down Clamps –
3. Remove both the black clamp and the color clamp. With the power on and with the printer idle, push the
Orange button under the printer lid. The cartridges will slide to the left, to the cartridge removal position.
Use your screw driver to remove the clamps. Put the screw driver blade in between the blue and black plastic
parts where the clamps are hinged, and twist. The clamps will pop right off. With the cartridges in the left
position, pull the power cord for the printer out of the wall, disconnecting the printer power.
"At this point, disconnect the printer power by pulling the plug out of the wall"
Install the CFS Cartridges -
4. With the power disconnected, remove the old cartridges, insert the new CFS color cartridges. There should
be 4 felt pads on each cartridge. You may have to guide these felt pads into the cartridge holder, it is a tight
fit. Push the cartridge all the way down, so it is seated at the bottom of the cartridge holder. If it is not seated
all the way down, the chip may make partial contact causing it to become unusable. Do the same with the
black cartridge. Both should now be firmly in place. You don't want them to be lifted by accident or by the
tubes pulling on them.
Next, install the nylon tie wrap, hold down strap, as shown below. It is important to get it in the exact position
as shown in the photo, so it will be in the depressed area of the chassis. See photo. This is your insurance
that the cartridges will not pop up and cause damage to the electronic chips on the front of the cartridges. If
you have "red light" problems after installing your CFS, it is due to the chips on the carts being damaged.
Careful here, they are delicate electrically. Do not use pliers or any tools to tighten the tie wrap, just your
hand strength. If it is pulled too tight, it will cause the black cartridge to lift up.
Install Tubing in Bracket and Adjust the Slack -
5. Put a little alcohol on the tubes at the position that will interface with the bracket.
Slide the tubing into the tube clip attached to the bottom of the bridge bracket. This is the bracket you
installed in step #1. With the cartridges still in the left hand position, make sure there is a little slack in the
tubing, not a lot but just enough. If you can't get the tubing into the bracket, use a little more alcohol on the
tubing.
Move the cartridges, by hand, from far left to far right. Make sure there is sufficient slack in the tubing so that
the cartridges can reach the far right and far left with out putting excess tension in the tubes. If you have too
much slack in the tubes, then the tubing will touch the bottom of the printer. Adjust the tube position in the
Tie Wrap Installation
Do not rotate the tubing.
