Hello and thank you for taking the time to help me out. We recently replaced a gear on the copier that interfaced with the fuser. Once put back together, everything was fine. During the day though, the print started to go light through out most of the printed pages, (this included both copied and printed pages). It appears to be associated with the drum unit, as I have removed it and cleand the contact points and now there is about a 5-6" portion of print in the center of the page that is light. The print is also somewhat blurry. Is this an issue with the drum after all or is it the corona wire? I haven't worked on too many copiers and this seems consistent with a drum issue. I truely appreciate your help and look forward to hearing a response from you soon...Regards, Brent

The grinding on this model is caused by one of the gears that interfaces with the fuser wearing down. In the process it pushes the bushing on the fuser out of position. Replacing the fuser may resolve your issue, but you should really replace the fuser and the gear. When you take out the fuser you will see an assembly of 4 gears on the inside-left of the printer. The bottom-right gear is the one that needs to be replaced.
The fuser is the problem. Most likely the fuser will need to be rebuilt or replaced. Google a business called The Parts Drop. they have either the parts or the unit.
You may just have to take the fuser out and remove a badly jammed piece of paper in that module. Shut the machine off for a half an hour. Remove the back cover. You will then see on the left side a black plastic bracket with 3 plugs on it. Disconnect those 3 plugs. Then open the right side door and toward the top is the fuser. It has yellow caution HOT labels on it. There are 2 silver phillips screws holding it in. Remove the screws and then remove the fuser unit and see if there is a paper in there. There are 2 screws that you can remove and the fuser will kind of fold open to inspect for bent fingers or one out of place.
There could be a few things wrong, but you most likely have a worn out fuser rachet gear, that drives the fusing unit or you may have a worn or broken fuser gear on the upper fixing roller. You can order the parts on line for about $20.00 + shipping. The only hard part is replacing the gears... The one on the Upper fixinfg roller is not that hard, but the rachet gear is kind of tricky... Alot has to come apart and then back togather. It is not hard, but you have to remember where the parts go back too. If you are not very comfortable with taking this apart, it may be a little to much to handel... It, could be just as simple as tighting the fuser screws??? Good Luck..
To access wires/connectors remove back cover 4 screws open and remove right door 2 screws on back frame one with small spring attached remove fuser unit with 2 screws unplug 3 connectors on back of copier. remove one screw on wire end of fuser/cut ty wrap with wire cutters be careful not to cut wires!! pull off cover remove heat lamp by pulling on copper end piece slide lamp up and out remve small c shaped retainer ring from end of roll with 2 small flatblade screwdrivers take off old gear and install new one-lubricate bushings with a few drops of fuser oil on both ends re-assemble in reverse order.
Interesting, you had a fuser handy. That is exceptional. I wish I had a key operator as handy as you. Now to the point. Since you had a fuser code you will need to go into service mode to reset this error. I know the copier said turn off and turn on and blah blah. I have no idea why they do that when its a known fact that a fuser code(for safety reasons) cannot be reset by the customer. However if you go into service mode, typically used by us toner monkeys, the code can be reset. Here is what you need to do. Press "additional fonctions" on the op panel then press both numbers 2&8 at the same time and then press additional functions again.You will see a new and wonderful screen called service mode. The topblock of several will say copier. Press copier. At the top will be several tabs and one will say "FUNCTION". Press it. At about the center of the screen you will see "CLEAR". Press clear. Now you will see a menu which includes "ERR". Press err and then in the lower right corner press "OK". This will indeed reset the copier and allow the device to forget its past problems and take a fresh look at the start-up process. Once you have pressed ERR and then "OK".... power the copier off by the power switch located at the far rear portion of the right panel. Power it back up in a few seconds and if the new fuser you put in is good, you will be back in copier heaven.TADA!!!! Good Job! Please be sure to return to "FIXYA" and let them know I helped you , or cuss me like a dog. Either way I truly hope this helps. Take care!!!! :-)
1. remove front cover which is over the paper tray - 2 screws and then unflange and wiggle off. 2. take out toner cartridge and drum cartridge. 3. there is a screw on the top left of the plastic cover over the fuser roller - unscrew it and then wiggle off the plastic cover. 4. there is a little green screw on the right rear of the fuser roller assembly - unscrew it. 5. remove the 2 white plugged in wire things to the right of the fuser roller (right one snaps on top and left one snaps on the inside right). 6. take fuser roller assembly out of machine. 7. loosen screw on left on top of brown riser and loosen 2 screws on right that hold the wired part down - carefully remove the glass heat element, taking care not to touch it with your fingers. if it is touched with fingers, need to clean it with alcohol to prevent the grease from reflecting the light back into the element. 8. remove the lock ring on the right of the cyclinder and then the gear wheel will be removable and replaceable. remember to take digital photos of it before you dis-assemble it so you will be sure you're putting it all back together right.
Call a tech!. You first remove fuser assy from machine. One green screw to loosen and then you figure the trick out to get it out. Then once its out remove cover 2 screws I believe. Remove the lamp gently, you can do this with out unscrewing anything. Then remove the little clip on end of heat roller, simple spread clip and replace gear. It takes a tech about 10 min.
Not a easy gear to get to, entire side frame must be removed. I always just replace the whole left frame as pictured, but really you only need to replace gear pic at top, like I say not easy, take pics so you know how to reassemble it.
