I just bought a Tektronix phaser 350 on ebay. I also invested in about $300 in extra ink sticks and a couple of maintanence trays. when I trun the system on, it starts to initialize and gives me the fault "04,005.44:7418" What does this mean? I have replaced the maintenance tray with no change. I have about $480.00 invested in this printer and was planing on using this with the business I am starting.
