51.10 Error- HP Laserjet P3015 Printer Laser Scanner Error
I ran into a HP laserjet  P3015  printer with an  51.10  error  on the display the other day. I decided after replacing the laser scanner assembly,  HP LaserJet Enterprise P3015 Series Laser/Scanner Assembly, LJ P3015/M525mfp RM1-6322-000
Troubleshooting the  51.10 error in the HP Laserjet  P3015 Printer
Really, troubleshooting the 51.10 error  in the  HP laserjet P3015 printer shouldn’t be  too difficult. The one I ran into it was right on the display and the machine wouldn’t do anything. If your customer complains of the 51.10 error and you can’t duplicate the problem then print of the error report in the diagnostic menu or in the same menu go to the component test and run the laser scanner motor test  to  see if the problem shows up again or if the laser scanner motor is sounding louder than normal.

Conclusion about the 51.10 error  in the HP laserjet  P3015 Printer
Hopefully the 51.10 error in these printers will not be a problem that happens a lot in the machine. HP laser scanner units have always been durable and reliable. I just worked on two other HP P3015  printers. One had 150,000 and the other had 200,000 prints with both being around 1-year-old  and the fuser  units still looked great. So  Hewlett Packard  seems to have worked the bugs out in that area compared to the P3005  model. From what I’ve seen with this model it’s still not a  P4015  but it’s a lot better than the  P3005 nightmare that it replaced.

Thank you. This was extremely helpful. 98 % of our machines are Lexmark I will be referring to this place when I can. If I use it enough I will definitely donate.
Thanks again.
