Method 2 - Black & Color Cartridges
1. Put a piece of aluminum tape provided (or electrical tape) over the outlet port to
prevent the ink leaking while refilling.
2. Turn cartridge on its side, as shown and make a hole in the side of the
cartridge using the Thumb Drill included. Make the hole on the opposite side of the sponge
which is the reservoir side.
3. Attach the needle to the syringe and slowly fill with the correct color ink.
4. Inject approximately 4 ml. of color ink into the filling hole or 8ml. of black ink into
the filling hole until the chamber is almost full. Unused ink may be returned to the
5. Seal the hole with the aluminum tape provided, black electrical tape will also work.
Additional Note: In some cases the sponge has deteriorated and
it cannot hold the ink and the ink will leak out the outlet hole. If this happens an
alternate method of refilling is to drip ink onto the sponge until it is absorbed,
however, your total page output will be less than a complete fill.
6. Replace the cartridge and run 1 - 3 cleaning cycles as per
Or print the following pages:
For best results, leave cartridge in printer for 8 hours after refilling so the ink can saturate the entire sponge.
7. Rinse the syringe with water and dry for further use.
Note: Be sure the white bar on the end of the cartridge is
Here is an alternate method: The filling hole
should still be drilled on the side of the inkwell. - - BUT drill it right next to
the partition that divides the inkwell from the sponge compartment and about 1/2 way
up. By drilling the hole at this point, the ink tank can be tilted at 45-degrees with
the sponge-hole (outlet port) clear to the very top (liquid can't run 'uphill'). (I'd
still suggest putting tape over the sponge hole.) The filler hole that was drilled
will now be to the 'top' of the inkwell and the ink can easily be
injected nearly level with the hole without so much as a drop of 'mess'. Wipe
the outside of the injection needle before inserting because even the smallest amount of
ink will "blow bubbles" around the hole and create a mess. When filled, make
sure that the surface around the hole is absolutely dry then apply a
small piece of aluminum (metal) tape. Finally, remove the tape that was covering the
sponge-hole and re-insert the freshly filled tank back into the print-head.
Note: On the end of the cartridge (opposite
end of the outlet port) there is two small reflective strips and a bar code like indicator
built into the label. The bar-code has both vertical and a thin horizontal bar.
These bars are very important in some way upon initializing the printer when a new
cartridge is installed. Upon refilling if the bar-code gets a little messy you will get a
message, "unable to print", "incompatible ink", or some other error
message. Either clean the ink off or replace the bar-code with one off of another
cartridge. You can even make a copy of the bar-code and use this to put on damage
Note: The printhead in the Xerox M940 has a sensor in it. After refilling, if
you have an air bubble in the cartridge the sensor sees no ink and tells you that you are
out of ink and stops the printing. If this happens you'll have to prime the cartridge by
turning the cartridge over and drip ink into the outlet port. You can thump on the
cartridge and this will sometimes move the air bubble up. Leaving the cartridge sitting in
the printer for 24 hours will sometimes give the air bubble time to move up.
The cartridge is divided into two chambers. One side with a
reservoir and the other side with a sponge. If you refill the cartridge before the
reservoir is empty you can alleviate this problem.
Comments from customer:
The H-100 is built differently than the Y-100. The Y-100 doesn't have an air vent while
the H-100 has a sizeable air vent running vertically next to the feed hole. The first time
that I refilled this huge tank I inadvertently over filled it because I didn't know about
the unique air vent so I had black ink running out of the air vent. A simple
suggestion [remedy] is to merely tape the vent and feed hole shut before refilling and
that seems to prevent over-filling.
I have refilled my cartridges so many times that I now have some more observations.
I'm discovering that each color of ink has it's own "personality" or
peculiarity. The easiest ink to work with is YELLOW while the worst is RED which easily
froths-and-bubbles and always makes refilling RED more difficult.
Any bubbles which form in the reservoir for the yellow ink quickly disperse and that color
of liquid ink doesn't "creep" via capillary action - - making it easy to put
metal tape over the refill-hole. The "viscosity" of the RED ink makes frothy
bubbles difficult to disperse and it's capillary action causes it to "climb" out
of the refill-hole - - making it more difficult to completely dry the area before applying
metal tape. BLUE ink is a close "second" with many of the same peculiarities as
BLACK ink "coats" plastic similar to the way milk coats the inside of a drinking
glass but it doesn't "froth-and-bubble". Because of the "coating"
action, it's necessary to lay that cartridge on the side with the refill hole facing up
and wait a few minutes for the BLACK ink to clear away from the plastic so that the
interior of the ink reservoir can be seen while refilling. Other than that, the BLACK ink
is easy to work with.
Regarding the spongy material by the outlet ports - - - I've found that the sponge either
"shrinks" or takes a "set" which doesn't allow good contact with the
connecting tube of the printhead. The most common symptom is any color which can print
small areas but fades out when trying to print larger areas. Without good contact between
the sponge and the connecting tube, the ink can't flow fast enough to keep up with larger
areas. When this happens, it's a good time to "top-off" the ink for that color
and then take the sharp point of the syringe needle and carefully stick it into the sponge
and lift it towards the outlet port without tearing it. The sponge should be flush with
the inner surface of the outlet port - - that way it will make good contact with the
connecting tube. When the cartridge is placed back into the printhead and run through the
cleaning cycle, you'll discover that it can now keep up with the demand for more ink.
On the XEROX WorkCentre M940 (and perhaps the others) - - When the printheads are put back
into the machine and the lid is closed, the status window asks if the BLACK printhead is
new (?) and likewise for the COLOR printhead (?) I've found that by always answering
"YES", this not only puts the printheads through the cleaning cycle but it also
re-initializes the sensors which report how full each cartridge is. This is displayed in
the status window and can also be displayed on monitor if a computer is hooked to this
I hope these observations help other XEROX WorkCentre users.
