One of our PRO-4000S printers has suddenly started draining the MBK ink (cartridge PFI-1700MBK). In the past, one cartridge would last us months. We haven't had any change in volume of work and yet the ink consumption has suddenly gone up for that one ink.
We installed a new MBK cartridge on 11/17/23 and had to replace it on 12/4/23 -- which was a bit shocking that the cartridge lasted less than a month instead of MONTHS. But then three days later, that new cartridge we installed on 12/4 ran out and had to be replaced on 12/7/23. Any thoughts on what is causing this with no change in print volume?
