That error is a firmware error, you might try again to download and install the update, or try a new memory stick if you have additional memory installed.

SOURCE: 50.9 FUSER ERROR
The fuser is the part that melts the toner onto the page, the error is thrown by a sensor which monitors the fuser, powering off unplugging and waiting for the fuser to cool (about 25 minutes, dont test it by touching it) before turning back on the printer will fully reset the sensor and may get you going again however this wont fix a fault with the fuser. However the fuser is a consumable which means they can be purchased and fitted by the end user (Not cheap parts), I always recommend that you users buy from the manufacture as they will stand over any item they sell you plus advise on instalation and problems however check prices on-line first and make your own call

For those users who are having a problem with the printer motor, this C level problem is referred to as 'developing disengaging motor rotation error'. Most likely, this problem points to an issue with the function of the DC controller: either it has failed or it has affected the developing disengaging assembly. The solution is quite simple and the user may fix the error in a matter of few steps.
The first step is to reconnect the J16 connectors that are used for the developing disengaging motor to the J1100 connectors that are used for the DC controller PCB (that is the printer circuit board of the DC controller). After connecting these two connectors to each other, the user must replace the developing disengaging drive assembly directly.
The final step is to replace the DC controller PCB, after which the printer is to be recalibrated. for more information....
