HP p4015 error 51.20

[Lbcoaster]

Had a Hp p4015 with a 51.20 error code, replaced laser scanner lasted for just over a month and 51.20 is back, very reluctant to replace the DC controller not sure this would or could burn out another scanner unit?

Any help is appreciated.
Thanks

#1.) Did you update firmware so we can eliminate that?

1. From the DIAGNOSTICS menu, run the
laser/scanner motor component test.
Verify that you can hear motor rotate.
2. If you cannot hear the motor rotate,
verify that the connections to connector
J86 and connector J93 on the DC
controller PCA are firmly seated.
3. Verify that the wiring harness at the
laser/scanner assembly is securely
attached.
4. If the error persists, replace the laser/
scanner assembly.

This is a weakness with these machines. Expect more replacements than usual.
