Chang your UHR and LHR with stripper fingeres, if it is not available at your country change the fusr unit it will resolve your problem feel free to contact me if you have any difficulties and rate me

Try doing a "stop test." You would induce a jam before the paper reaches the fuser.

Just open a cover while printing and hopefully some image has been transferred to the paper. If the defect exists already then the laser unit, or document scanner may be causing it.

If that eliminates the dark streak, then obviously the fuser FG6-3720-000 should be changed.

If you have the black line on copies and scans but printing from P.C is fine, then your scanner is broken.

Contact your printer manufacturer for a replacement or repair.

IF YOU ARE ONLY GETTING THE LINES WHEN YOU PUT THE DOCUMENTS INTO THE TOP FEEDER AND NOT FROM PRINTNG TO COPIER OR IF YOU PUT A COPY ON THE GLASS UNDER THE DOC FEEDER AND NO LINES APEAR CHECK THE SMALL GLASS WINDOW UNDER THE DOC FEEDER THERE MAY BE SOME TIPEX OR INK RUBBED OFF AND LEFT ON THE GLASS THERE.. THISD MIGHT BE CAUSING THE STREAKS YOU CAN CHECK THIS BY PUTTING THE PAGE IN THE DOC FEEDER AND DOING A COPY AND THEN PUT IT ON THE GLASS PLATE UNDER THE LID AND DO A COPY OR IF HOOKED UP TO COMPUTER DO A PRINT JOB.. IN NO STEAK APPEARS YOU CAN BE SURE ITS ON THE THIN SCANNER GLASS.. GOOD LUCK ...a

Light copies> could be related to toner or ROS unit (laser unit)
