hey fellas..am having a 2721 error. It came out of nowhere. I check the separator pole connection as well as the other end of the connections.Still getting the code. I adjusted the connector and made it a little tighter cause it felt a little loose compare to other printers were i have done pm's. Also checked contacts on transfer belt and back panel. Everything seems to be ok. The printer was pm about 2 months ago and wasnt been use for production, just testing different graphics jobs. so it only has about 4k after pm. Any of you has run into this particular issue??
