GR3750 Pressure Roller Replacement?

**The Future** · 12-30-2012

Hi all,

I have a new pressure roller for my 1.5mil copy GR3750 but am having some trouble determining the proper way to install it. The manual I have seems to indicate it needs to go through the back of the machine. It also seems like it could be installed through the front of the machine, once two screws on the Pressure Roller Holder are removed on the (though the screws on my machine are quite tight and its hard to tell if they are phillips or hex -- might be stripped?).

Any assistance would be appreciated.

There is only one screw that needs to be removed, if you look at the front bearing for the pressure roller that is in the machine there is a large phillips screw that's head slightly overlaps that bearing, remove that screw and pull the pressure roller slightly towards the front of the machine and it will come right out.
Kind of sounds like you may have been looking at the instructions to disassemble the pressure roller mechanism, though. Something to be avoided if at all possible.

Looking at the roller from the front, Im not sure where I locate the bearing and the single screw. I still only see a set of two screws pointing down (7 in the attached diagram) that seem to hold the roller in place. Which way is the screw oriented? It's on the inside of the machine correct? The only bearing I can find on the part diagram is 17 which is alined with the roller guide not the roller itself... Sorry to be a bit thick on this.

I NEVER removed any screws to take the press roller out. It will just pop and and the new one will pop back in. Just be sure that the bearings get seated correctly. It's a 2 second job.
