Digital BW, The Print

Thanks! I still can't get it to work, but at least then I know this is a general problem with these cartridges and not just my printer in particular. 

Considering your solution to the problem it sounds to me as if there is an alignment problem with the chips on the MIS cartridges.

The 4800 and 7800 use the same cartridges, so it's not unlikely your solution should work for me as well. Where exactly do you place these shims and how thick are they? 

I tried inserting several strips of 310g matte paper under the cartridge when inserting into the printer, but it didn't help.
