Hi Everyone –
I think I have found a solution to my own question.
So, If all the OEM cartridge chips are working, but the refillable cartridge controller chip doesn’t show up – check this one thing.
I found it be accident. The controller chip is a very smart idea and should work if they are installed with care. I tried a number of things, used contract cleaner (Deoxit) with swab to gently clean the contracts on both the OEM chip, the controller chip, and the mateing printer contacts. Be cautious and watch for loose fibers from the swab.
The controller chip is held onto the plastic holder with little nibs or tits of plastic that align the chip so that it should align with the printer contracts. I noticed some of the leading edge plastic nibs are a touch high, maybe a 1/32inch – just high enough to lift the printer contract wire up so that contact is not made with the gold contact just aft of it. Look at is horizontally and you can see the extra height on the nib. So, using an exacto knife or sharp razor I cut the plastic nibs down. The chip will still hold it’s position, but contact will be made.
Maybe this will solve some of the problems with some of the refillable cartridges not seating and making contact. It’s better than trying to alter the position of the cartridge with shims of paper, etc.
I made one mistake however. In switching back and forth from OEM to refillable repeatedly to test everything, remember that the chip when put back in the OEM cartridge is just resting in the indent on the top, so when I ejected the cartridge the OEM chip went flying back into the printer. Tried everything to retrieve it but hopefully it in not in the gear mechanism – otherwise another larger problem. Still waiting to print with the Piezo inks,
