Digital BW, The Print

Hello Paul,

Do you find you have to be careful with that ammonia? I (stupidly)
took a whiff of it once and it really burned my throat... someone on a
forum somewhere suggested I not use it. But you apparently have found
a way to use it safely. I'm tempted to try that on my R220 rollers
which have trouble grabbing heavy stock.

Paul
