I bought this complete imager kit because of streaks and lines in multiple colors when using my 10 year old Lexmark printer. After installing the kit the color reproduction got even worse, the magenta and cyan drums were defective and as a result the toner was all over the inside of my printer rendering it inoperable. I've tried cleaning it with swabs and wipes soaked in isopropyl alcohol but to no avail. I'm afraid my Lexmark will be sent for recycling soon. The only highlight about this purchase is that Revain stood behind the sale and gave me a full refund for the imaging kit. There was no way they could know that there were defective parts inside.
