Xerox 8R12728 & 8R7971, 72, 73, 74 Il y a 3 Années, 5 Mois
Hi,
The H-100 (8R7971) is built differently than the Y-100 (8R12728). 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 RED ink.
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 all-in-one printer.
I hope these observations help other XEROX WorkCentre users.
D.P.K.
