Sharp AR-M237 Copier

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

How to replace a pressurization fulcrum arm on the fusing unit of a Sharp ar-m 237 copier


The fuser needs to be removed from the copier first. If you have the part it is not to hard to take the fuser out. Turn the copier "OFF" first & unplug the copier, remove the transfer unit from the right side, then remove the back panel of the copier ( 5 screws ), then unplug the fuser unit ( 3 connector ) , then reove the top right cover ( 2 screws ), then you can see the 2 top screws & the bottom 3 screws, remove them and the fuser should pull out toward you. Replaced the broken fulcrum arm and reinstall the fuser in revese...... Good Luck
