Laserjet Pro M521dw "52 scanner error"

[PLI_NL]

Our Laserjet Pro MFP M521dw gives a 52 scanner error when printing, the print job gets cancelled. I have switched off the printer and removed the power lead for 30 seconds and this didn't solve the solution.

The scanner works perfectly and when printing a demo page directly from the printers menu it gives the same error.

Any suggestions?

Thanks!

Hi

The product has experienced a scanner error.

Turn off the power by using the power switch, and then turn on the power and wait for the product to initialize. If a surge protector is being used, remove it. Plug the product directly into the wall socket. Use the power switch to turn the product on.
 If the issue persists, keep the printer turned Off for 3 mins and turn it back ON.
 If the Issue persists service the printer.

Hi VK14,

Thank you for the quick response. I have done all this already.

By servicing you mean bring it to a service center to be diagnosed? I'm quite handy myself and will be able to replace the part, as long as I know which part needs to be replaced.

Thanks!

Hi!

Thank you for the reply, If all the Troubleshooting steps has been performed then it could be an issue with the Laser Scanner Assembly (part RM1-6322).

I have the same issue, was the scanner assembly difficult to replace?  Thank you.

Hi Tamvet,

It's a fairly simple task if you have some technical skills. You just need to remove some screws and disconnect some connectors.

I have used the repair manual from the following link:
