"49 Error" alternating with "Ready"-Laserjet Pro CP1525nw

Just put the printer off. Push OK and right arrow button simultanuously while setting the product to on. Wait a little bit. Ready to go!!! That is what I did, works perfectly!

Did you ever solve this problem?   I'm stuck in the same situation.

Try an NVRAM reset. See instructions below and read the caution statement.

NVRAM initialization
CAUTION: All HP Jetdirect settings are also reset. Be sure to print a configuration page before
performing an NVRAM initialization. Make note of the IP address that is listed on the Jetdirect
configuration page. You need to restore the IP address after performing an NVRAM initialization.
Performing an NVRAM initialization resets the following settings and information:
● All menu settings are reset to factory default values.
● All localization settings, including language and country/region, are reset.
After performing an NVRAM initialization, reconfigure any computers that print to this product so that
the computers can recognize the product.
Perform an NVRAM initialization
1. Turn the product off.
2. Simultaneously press the right arrow button and the Cancel button. Keep these buttons
depressed as you turn the product on.
3. When the Permanent storage init. message appears on the display, release both buttons.
4. When the product has finished the NVRAM initialization, it returns to the Ready state.

If the reset works and you do not get a 49 error on the initial boot of the printer, then put back the original ip address and see if it works. If you now get the error, then you still have a bad print job trying to print. If you get the error on the initial boot, then the formatter needs to be replaced.

Resetting the NVRAM did the trick.  Thanks!

This worked for me.  Had to rebuild my settings but that wasn't a big deal.
