QTR-Quadtone RIP

I don't know.  However, I just found a resister that is supposed to work
with ARC chips. It's on order.  When I receive it, I'll let you know.  I
also have the same problem.

 

BYW, thanks for all you do.  I'm just getting back into BW printing and am
mixing up a batch of Eb6-HP for my R1800.
