C88 by wnnelson

I modded a C88 without hacking the frame. I made new bushings for the drive shaft which lowered it by .100". {ed: the new bushings were turned on a lathe to match the shape of the originals on the outside, and then an off center hole was drilled in the inside to hold the shaft in the lower position } I trimmed off {ed: turned down on a lathe} the outfeed rollers to give a flat carrier path and moved the paper sensor to the front. This allows a carrier with no cutout notch for the timing. {ed: because the edge of the tray now triggers the sensor} I put a smaller gear on the end of the drive shaft for the vacuum pump because there was no room for the original gear. {matching a gear like this can be quite difficult. If anyone knows the source of this gear, please share it} This causes the pump to run slower but does not seem to affect the operation. I hope this will help with the clogging problem as the cleaning station has not been modified. I added a little tubing to the pressure rollers to give it a little extra pressure as the carrier is too far away for the regular roller. So far it is working great.
