This toner easily replaced the original cartridge, and costs only one third of the original product. The chip and therefore the amount level are recognized by the printer immediately. In Dell's menu I need to put a check mark to use a toner accessories. When printing text at all, no difference should be noted; for A4 black and white photo print of original toner is somewhat brighter. Hardly noticeable. Can these toner so without hesitation, at least for the Dell 1765 recommend. Shadowing, which describes the last speaker, I can not observe at multiple printing.
