Umm, yeah..... you have to be a little more specific.

make a cold reset or NVRAM reset
To do a cold reset you power on the printer while
holding down the go button for about 5 seconds and then release the
button. If the button is held for more then 15 seconds it may do a
NVRAM reset
SOURCE: HP Color laser jet 4700n 49.3048 service error
The problem is usually caused by printing a PDF file with fonts/page size/ page formating errors which will cause the printer to display the 49.3048 error. The only way to use the printer is to POR or recycle the power and delete the print job from the server or spooling device and cancel it on the printer before the offending command is issued to the printer again. You can try updating the firmware to the latest version 46.140.5 from the HP website. MIke L.
