Problem with a LJ4700 Fuser Message...
I've been watching as the old fuser wound down to 0% on one of our LJ 4700DTN printers. Finally today the message on the printer screen says to change the fuser; which I did. The message won't go away and the status page is still showing 0%. It's not likely but possible that the replacement fuser from HP was bad so I tried another brand new one, and still no luck. As per the instructions: raise the lid, remove the old fuser, install the new fuser, close the lid. No power down or resetting the printer called for? As I recall, there is now manual way to reset the fuser? Any help would be greatly appreciated.

LJ4700 Page Reset after fuser replacement...
There is no option anywhere on the LJ4700 menu to reset the page count. I went into the service menu (09470005) there is no option in there either. I have discovered that the fusers have circuitry built into them that that will reset the page count one time only when installed. Below is an excerpt from an HP support site!
CLJ 4700 Series Fusers— important notes:
• The original fuser that comes inside the 4700 series printer has a part number of RM1-1719 for 110V, and RM1-1734 for the 220V version. The original fuser has no page count reset circuitry, since the fuser and printer are already starting at zero.
• The HP LaserJet 4700 family of printers has no fuser page count reset mechanism accessible via control panel or computer screen, but, instead, relies upon the reset circuitry that is built into the replacement fusers for this series, to reset the page count automatically.
• The replacement 110V fuser is RM1-3131, and the replacement 220V fuser is RM1-3146. (These are the fusers that come in the Q7502A and the Q7503A kits.)
These replacement fusers contain the special circuitry that causes the Color LaserJet 4700 printer to automatically reset the fuser use page counter upon the first power-on cycle after the replacement fuser has been installed, so that you can keep track of number of pages printed by the newly installed fuser. This special event will only happen once, when the printer is powered up for the very first time
So, if a customer decides to take a good fuser from one CLJ 4700, 4730, or CP4005 printer and installs it in another of these printers, the fuser page counter will not be reset. Only brand new, or properly remanufactured fusers, with the part numbers of RM1-3131 (110V) or RM1-3146 (220V), will reset the page counters, and they will only do that the one time. Most remanufactured fusers of this type cannot reset the count.
