I recently obtained a Phaser 340 off surplus. My problem is the printer displays "Fault 07,0004.46:21038" and "service required" and refuses to start up. The Tektronix web site said to change the maintenance tray, which I did and if that didn't work the printer would need service. My dilemma is that I got the printer really cheap and a don't know if it would be worth taking in for service. Can anyone tell me what this error really means or where I could find some type of service manual for this printer? Any help would be appreciated.
