Always a new wrinkle....Today, I can't make our fairly recent 3880 recognize even one IJM cartridge. I mistakenly loaded it last week with the M and LM carts used with our 3800's, realized the error, and replaced those with the VM and VLM correct carts. Those two positions reported OK, but all the others flashed the "load cartridge" message. Today, none of them, not a single one, is recognized. I removed them, loaded up the OEM carts, and everything is recognized. Opened the ink-lid, turned off the printer, replaced with IJM carts, and...no joy.
Seems unlikely that ALL the OEM chips would suddenly be bad, right? Just to see if one might be dead, I swapped in a different OEM VLM chip to a VLM cart. No change.
Having used IJM carts (just for Piezo-Flush) in this printer, and three others for a few years, I'm used to the fact that you have to fuss with them to get the printer to see them. Usually, pulling them upwards during or after seating in the printer takes care of it. In some cases, I have to shim them up.
However, I'm stuck here. Nothing is working. Any ideas, anyone?
