HP LaserJet 4 Streaking

It is correct to assume I know VERY little about printer repair. I have an older LJ4 that began having a streak (3/4" wide) about 2" from the left edge of the paper, the remainder of the print is great. I cleaned everything in sight and then pulled the flap back on the toner cartridge and saw a big streak of toner on the green roller. I cleaned this off but the streak quickly returned. I thought a new cartridge may help but the same thing occurred. I am a student that needs the printer and very little $$ so is there a fairly quick and inexpensive lesson to be taught?? I appreciate any help! - gc
The streak you refer to is caused by a bad wiper blade in the toner cartridge. The wiper blade cleans off toner that isn't transferred to the page and deposits it in a waste receptacle. I assume since you're a student with little cash that you bought a "refilled" toner cartridge. I'd take it back where you purchased it and ask them for a good one, preferably one where they put in a new wiper blade.

Clink,could be that your fusing roller has toner baked on. some are accesible and can be cleaned some not. have cleaned up several on different model printers but the 4 not just sure good luck.

Fuser streaking is more of a ghost image and is always in the center of the page, not to one side. Problem is definitely a bad toner cartridge. Final answer!
