Digital BW, The Print

When we had a bad clog on a 3000 and didn't have any Windex, it was suggested we use a denatured alcohol and water solution of 1 to 10 by the Piezography folks. I don't remember now whether it was Jon Cone or one of his tech support guys. Anyway, it worked. The printer hadn't been used for a couple of weeks. We followed the instructions on Jon's site. It took three tries and three days (soak and wait), but it worked. In between we used paper towels to soak up ink from the pad under the printheads.

  Denatured ethanol (AKA: denatured alcohol) was / is the choice of printhead manufacturers / remanufacturers. When they recieve alleged "defective" heads due to clogging etc, they use this to "cleanse" the jets, typically by total immersion into an ultrasonic bath of denatured ethanol cut with purified water 40/60. (if memory serves). I have a pdf of a current MSDS sheet on denatured ethanol for anyone's review,  just request it off-line. 
  Glad to help, - JT
