MG8120 printer won't read cyan resetable chip.

I had purchased a set of refillable cartridges on ebay a couple of years ago. A couple of months ago I noticed the cyan chip would not read. I replaced the cartridge with the Canon cart and it worked. I then went on line and bought a set of resettable chips. I replaced the cyan chip on the refillable cartridge with one of the new chips. The printer read it the first time and I turned the printer off and back on, then the printer refuses to read the chip. I tried moving the chip around on the cartridge nothing helped. I even tried cleaning the pins that read the chip still no luck. I also tried removing the cartridge and replacing it in the printer.

Ok... so to be sure I understand this properly...

1. You have a new ARC (auto reset chip) on the Cyan cartridge
2. The ARC's on the other cartridges are the original ones that came with your refillable cartridges originally
3. The cyan ARC was initially recognised but, after a power cycle (off/on) the chip is no longer being recognised

If that's the case, it's entirely possible that the new ARC is programmed differently from the original set and just doesn't want to play ball.

The solution to try is to chip swap ALL of the remaining cartridge chips (like for like obviously. ie: Magenta to Magenta, etc..) and see if that resolves the situation.

The reason I'm suggesting this is that usually the chips all rely on each other to a certain extent and won't play ball with other ARC's so a complete set tends to work when a mix n' match won't.


If that still doesn't work then your best bet is to source some OEM cartridge chips and get yourself a chip resetter. In my opinion that's a better way to go anyway but I'm biased

Hope that offers a solution but keep us posted either way.
