Streaking, smudging, black lines, and double images are all symptoms of a bad fuser. When you notice these printing defects and experience problems, such as paper jams or wrinkles, this is a good sign to replace the fuser kit.
The fuser unit must be replaced every 100,000 pages, usually along with the transfer belt and feed rollers as part of a maintenance kit. The error code 010-351 indicates that the fuser has reached 75,000 pages and as a result has 25% life or less remaining.
The message `Fuser Error` or `Self-Diagnostic` means either the fuser has reached the maximum temperature allowed or there has been an error in detection of the correct temperature during specific times of the printing process.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.

fuser
ANSWER : You can buy just the upper fuser roller that is the cause of your problem. The real problem is that there are no instructions for rebuilding the fuser. The Brother fusers are a bit difficult to take apart.

Need help
ANSWER : I usually look for screws that might be holding it. If it doesn’t come off after removing the screws, sometimes you have to slide it to remove it. If that doesn’t work, then you get out the small, flat bladed pocket screwdriver. Use it to gently pry around the edges of the panel. Have you tried grabbing the paper clip with some needle nosed pliers? Either that or a small magnet to pull it out. Another possibility would be to hook the clip and pull it out that way.

Toner cartridge full, printer displays: "empty needs replacing"
ANSWER : I once went to a customer who had a similar issue. They had installed new cartridges and judging from the box, they looked OEM. Strange thing was they felt empty when lifted and they were missing the chip on the outside that tells the printer it is installed and keeps track of how many copies were printed with that cartridge. The printer has no other way of knowing if the cartridge is full or empty.
