Black toner won't print event though cartridge is full on HP Photosmart 5255

Two options which you may want to try.
1) Use cleaner that you may be able to grab from one of the computer shops and try cleaning out the printhead with it.There is a possibility that the ink has clotted or the printhead itself needs replacing.
2) Try another black cartridge from a similar working printer

Check the drum unit. Rotate the optical cylinder slowly, looking for a scratch or clot of toner on the drum. You may need to clean it with compressed air or VERY gently with alcohol and a cotton ball. If the drum cylinder is clear of defects, check the fuser at the back of the machine for the same. A drum can be cleaned or replaced, a trashed fuser is not repairable. It may also be cheaper to replace the machine than to replace the drum of course.

Toner marks

Your Drum Cylinder has a scratch or clot of toner stuck to it. Every time it rotates along the page (usually 4 rotations per A4) it leaves a copy of the defect on the page. If you take the toner cartidge out of the drum unit, you will be able to turn the drum cylinder until you find the fault. Either replace the drum unit or CAREFULLY clean it with alcohol on a cotton ball (meths or iso propoyl will do) in the case of a toner clot. If the fault recurs quickly after cleaning, then you have a damaged drum and it should be replaced.
Best of luck.

Light streaks and gray streaks and little contrast.

Sounds like there are multiple problems on this machine. Dirty optics can cause light images, white streaks can be caused by dirty cortron wires(becareful when cleaning the wire or all the wires 3 usually, Q-tip can help) , not enough toner in the ink hopper, dirty cleaning blade in the drum modual. A bad heat roll can cause streaks also. Background with light images and black spots can be caused by competitive toner not working very good.

Blank Streaks

streaks are caused either by the toner, drum, lamp or fuser.

If you make a copy and it does not show a streak then it was done by the person sending the fax. BUT, check this,

open door and take out toner cartridge. look for a thin glass that is on the bottom of the machine and wipe it. Toner spills will cause a black streak.
