Chips won't reset on my 7900

None of the chips will reset on my 7900. I have the ACC-RESET-7900-WT-USB chip resetter.
Won’t work on the ink carts or the maintenance tank. The resetter rapidly blinks red then stops.

You have only the WT (waste tank) resetter. It will not work on the cartridge chips. Using it on the cartridge chips will damage it and make it not work on the waste tank.

This printer requires two resetters: the waste tank one, and the cartridge one. It’s just the way Epson designed this particular printer configuration.

You’ll need to order the cartridge chip one. I get Wells on the horn Monday about replacement of the WT one.

best,
Walker

Thanks Walker,

The instructions are a little confusing as they describe resetting both the waste tank and ink cartridges.
