plastic is plastic,so it is meant to be the weak link..and crack,break etc..........'I like that they go honestly,a very easy service $$$$call and if it happens a few months later i end up popping in a new pressure roller as they cause "bounce" from all the flat spots..
hello, this is one of the most classic problems on that machine, when you rebuild the fuser, or change the gear, I suggest you also replace the bushings of the fuser roller, because by consuming they work the fuser roller with an oscillating rolling effect, which makes sting the gear teeth accelerating the break when the material is cooked
Bad engineering... Typically, a gear with a flat area to prevent rotation on it's mounted part will break in the corner of the flats at the thinnest area. Ricoh gears break in the middle of the curved area on both sides. The gear tries to spin inside and widen when it stretches and fails. I believe that if it had a flat spot on one side only, they would last longer. Agree that the problem root is flat spotted pressure rollers.
It kinda DOES matter considering the new style fuser gear you can't use for those older fusers.
They were redesigned for the MP6002 and upwards.
You asked and you have your answer.
YES they redesigned the gear but you can't use it on an old clunker like a 2075 or an 8000.
And to answer your next question yes...they do still break,just not as frequently
