Ink Jet Case Coders
We have had Marsh for about 7 years. We had loads of trouble with the hi-res barcode heads. They were not very robust, they seemed to break easily. And we have had some trouble with the low-res dot matrix type heads that dry up during periods of downtime.- yzracer

Changing blower/pulley speed
I need help finding the formula and using the formula correctly to change speed on a electric motor / v-belt driven blower. The blower pulley is a 3v3.65 3sh turning 3400rpm and the motor pulley is a 3v6.9 3sds turning 1750 rpm. I need the blower to be turning 2750 rpm. How do I figure this out...- yzracer
