My LaserJet 5M is turning entire sheets of paper gray and I think I've figured out that the problem is the cartridge wiper blade. This happened a year or so ago and I replaced the cartridge with a "new" HP one but now I've had to replace that one for the same reason and cartridge #3 only lasted a few weeks before it started doing the same thing. Apparently the wiper blades go bad even when the cartridges are not being used and since HP stop making them years ago that would explain why "new" cartridges aren't lasting.
Its supposedly easy to replace the wiper blades but they don't seem to be so easy to find. That is unless I want to get a quote for 1,000+ of them from China. I had found a website and stupidly didn't bookmark it and haven't been able to find it again.
Does anyone know of a site to buy toner cartridge parts like these blades? I think the cartridge is the same for the HP LaserJet 4 and 5 (and my 5M which was the Mac version with PostScript SIMM and a Mac-style serial port).
Alternately, any recommendations for a place to buy a remanufactured cartridge? I'd been avoiding them but now that may be the only way to get a decent one.
I know this is one place where I won't get a response of "
wow your printer is old! Just get a new one."
