| I thought I'd save a bunch of money by buying "high-quality" inkjet cartridges from an online vendor at just over half the price of the Xerox cartridges at my local office megastore. They even looked to be built very nicely, when I got them. Unfortunately, I discovered that the REAL difference is the ink itself, and it really matters. The ink in the clone cartridges suffered from two serious problems that made it a really bad buy: 1) It's way too watery, and so it causes the paper in solid colored areas to get wavy, and 2) It dries far too slowly, so while the Xerox cartridges can print, say, text on a light grey background, trying that with the clone cartridges resulted in the text bleeding badly with the background, becoming almost unreadable. Learn from my mistake - the Xerox cartridges are worth the difference, and Amazon's price seems pretty good. I'm only buying real Xerox ink cartridges for my M940 from now on... Xerox cartridges are easy to instal and the indivual ink tanks reduce the cost of printing and save you money. Its great that when one color runs out that color only has to be changed instead of throughing out the entire thing. Xerox has made ink-jet printing affordable. |
