CHATSWORTH, CALIFORNIA -- I purchased a $27.19 "New Genuine Lexmark #36XL Black 18c2170 36xl" from InksJetsWorld on 5/3/12. Although it says it is a genuine Lexmark cartridge, my Lexmark X6675 printer will not accept it and says "cartridge error" and tells me the cartridge is not compatible with my printer. The cartridge looks identical to the one I bought at OfficeMax, except the code numbers on the back of the cartridge are different.
Office Max code says P10 (which worked fine) and InkJetsWorld cartridge says P2 (which does not work). I bought this replacement cartridge to have on hand for the next time I run out of ink (I work from home and have to have a spare on hand). DON'T ORDER FROM THIS COMPANY. THEY ARE FALSELY ADVERTISING GENUINE CARTRIDGES.
