I didn't use the cartridge much, maybe a month, maybe 50 pages. The print was always lighter than what I usually get from HP, but I figured it would be ok. Then I tried to print some labels and the printer started leaving sticky marks in the form of specks on the labels and on the back of the sheet. I'm afraid to use it now and I have another new one (2nd) that I haven't even opened yet. A quarter of the price but not worth the cost of a new printer.
