“Fortunately, I ordered 2 x 4 Packs for my Dell E525W printer,
because the Black cartridge did not work.
Comparing the 2 new cartridges, I noticed that one of the Black cartridges
was different ... it did not have the top piece that appears to cover the toner refill.”
“I bought all four toners. So far I replaced the yellow toner and it didn't work. My dell e525w printer didn't recognize the replacement toner. I am planning to buy an original from dell instead of wasting anymore money.”
“We bought this laser toner in November but just put it in our printer now, since we were using up old one. This does not print well, it is VERY light. I would be better to leave the old toner in. I am very unhappy with this product.”
“Seem to work ok in my Canon printer, although the individual cartridges were not marked with Cyan, Yellow, Magenta or Black on the cartridges, which would REALLY HELP installation. The only way to tell what color resides in which cartridge is by pulling off the protective tape, to see what color ink dust is on the tape, so then one knows where to install the cartridge. But once the "tape" is pulled off, you have to complete installation. BUT I guess that's why they're sold at a reduced cost.(?)”
