I Have A Pt-110. Inside The Tape Compartment I Need The White Arm With Roller.

I have the same problem.  5 years ago the white arm snapped off around the Pivot post.  I was able to Crazy glue it, Let it sit over nite and it should hold. Mine did for 5 years untill I dropped it again and it broke in the same place. I just reglued it.  It looks like it will hold.  unfortunatley I lost the "jesus clip"  and have to get a replacement. I called Brother and they said look on thier web site for repair shops (vendors) in you area. the either don't have the part or want to sell me the entire module, Gears, Motor, metal base.  I'm not paying for that.  I Will find a "jesus clip" at my hardware stoe and fix it for another 5 years untill I drop it again an the white plastic breaks again.  It is a great reliable unit and I will be ticked off if I can't find an 8cent part to repair it.
