I've only had a Phaser 6510 for about 2 months until it stopped working. It lists "Completed with error 016-748" each time I try to print a job, except it doesn't, in fact, complete the job. Xerox customer service has been no help, as nobody there seems to know how to fix it, and even the on-site technician that they sent has been stumped. The "warranty" states that if Xerox cannot fix it they have to either replace it or refund the purchase, but they are so far (3 weeks and counting) refusing to honor it. Has anyone else had this issue? This error code appears on at least one other forum here, except any of the suggested tips have not worked in resolving it. Thanks.
