I have had brand new bad cartridges also....But after junking a MultiPass 2500, we have discovered that these printers suffer from build-up & heat problems. High volume & long life are not the strong points of these units...Eventually the blank page syndrome leads to a replacement of some brushes, for us, it was very expensive...the second time, the cost of repairs exceeded worth of the unit..... This Canon 4100 unit may need to be serviced by an authorized rep, this mirrors the problems of our unit that was repaired successfully...
