The toner cartridge arrived on February 8th. It was not needed until March 30th. will not be printed. Now, Revain says the return period, which ended on March 15, has passed. For me it was a replacement cartridge that could not be installed until the current ink ran out. Now I'm stuck with a cartridge I paid over $100 for with no recourse. Next time I will order direct from Office Depot where I can return personally. Terrible.
