Unable to print, copy or scan. Have powers unit off and on many times.
Each time a print job is sent to the printer, 49 Service Error appears and the printer reboots.
Moved from Printers - LaserJet to Multifunction and All-in-One

We have a client with an HP Laserjet Pro 400 colour MFP m475dw that developed a 49 service error. We disconnected it from the network, powered if off, and worked with HP phone support with no resolution. We happen to have the identical printer in our office, so we swapped them out. Again, even with the new printer we got the same error, we took the clients printer back to our office and it worked if. Two printers, 40 service error at one location but not the other. Any ideas?

I'm having the same problem despite the fact that the printer is disconnected from the network including all USB ports and I had it unplugged from the mains for at least 10 minutes at a time several times. Once it is powered up it goes back to its loop of re-booting itself and displaying "49 Service Error" "Turn off and then on" - it does it continuously until it is switched off.

Perform an NVRAM reset, clear all print jobs and then try again.
NVRAM Reset for HP Color LaserJet m375/m475:
1. Turn printer off
2. Touch and hold the right arrow and the cancel button
3. Turn the printer on
4. Release the buttons when the message "Permanent Storage Initialization" appears
5. Reconfigure your printer
49 service errors normally mean that there was a bad print job sent to the printer. The printer did not know how to handle the problem and waits for user interaction to clear the job. For us this normally happens when printing PDF documents. We can normally work around that problem by enabling the Print as Image feature from within the PDF settings.
On that note, normally finding the job on the print server and deleting it followed by a reboot of the printer will clear the error message. If your 49 error is appearing on the screen while not connected to anything and rebooting then that means the job has moved onto the local memory of the printer. This is where the NVRAM reset should help to clean up any corruption.

I had an administrator M475dw with Service error 49. We cleared his print queue, did an NVRAM reset and the problem was solved. (I also showed him the "Print as image" setting in Adobe).
I have two other M475dw that are initializing over and over with Service Error 49. They ignore the buttons to reset NVRAM.
They won't stay online long enough to accept a press of the cancel button (trying to clear a bad job).
These two users cannot use their printers. They turn them off because the constant scanner initialization is annoying.
This is not your regular Service error 49. Normally clearing the print queue(s) and reset NVRAM does the job.
I'm considering replacing the formatter on one of the problem units to see if I can get a fix.
Any input would be welcome.
