I have an HP LaserJet Enterprise 500 printer, specifically the m551dn (this advice also applies to the m551n and m551xh). Recently vertical streaks started appearing on many printed pages. Repeated cleaning cycles did not fix the streaking.

I contacted HP, and they said to take out the transfer unit and see if there were toner streaks visible on it in the same position as on the printouts. There were, and when I told them that they said I would have to replace the transfer unit. It costs around $400, half of what I originally paid for the printer, so I decided to look for other solutions.

I cleaned everything out as best as I could, again while wearing a mask for safety. Note that the grey grate shown in the photo flips up to give you access to stuff on underneath it. After tapping out as much loose toner as I could, I use cotton swabs to clean all the parts near the transfer unit. I also carefully slipped a piece of paper between the transfer belt and the rubber strip underneath the grey grate and ran it the length of the strip to attempt to rub off any toner that might have been stuck on the underside of the rubber and causing the streaking. Then I put everything back together and put the transfer unit back into the printer. So far, no streaking.

Thank you for these tips. I managed to tap out a lot of excess black toner, but did not remove the tabs to get to the small panel. So far, it is streak free but I may need to repeat this procedure and remove the panel if it starts again.

I added a HP laserjet 500 M551 to a windows 2003 R2 server, acting as a print server. I can print from the printserver, but I can not share it. It tells me "sharing is not supported for this type of printer".

So the problem was I was connectin the printer as a "Network printer" - which in my understanding was correct, since the printer was connected via tcp network. BUT my understanding was wrong. Since the printer server is to act as a spooler for this printer, the printer is considered "Local", even if it is not local in any general sense. So I reinstalled the printer als a "Local" printer, and then I could share it.
