I have purchased several cheap color printer cartridges for an old Lexmark printer. They came from vendors with different names and supposedly were new Lexmark (didn't say refilled) tho the prices would suggest otherwise. Just wondering what causes them to change color. They start out printing black as expected. Eventually after a few months of quite low usage, the first 20 or so lines on are page are black (or dark blue) and the rest are magenta.
Interestingly if the printing is stopped for a few minutes (paper jam), the first few lines on the next page are black and then the rest are magenta.......almost like trying to pump too fast from an oil reservoir and some colors can't be replenished fast enough.
I mainly care about being able to read the document so the color change isn't a major problem. I don't know total page output compared to what a
good cartridge would do ........only that the good cartridge costs 3-4x as much. Strange that product from 2 different suppliers does the same thing.....perhaps the supplier is the same operating under different names because of the poor quality or perhaps it is one supplier and 2 importers.
