Thanks for the leads. We currently have a 3100 and 180. Honestly I don’t mind doing registration on the 180. Seems like the 3100 is hit or miss at times.slaterlee.com has a V3100 they're trying to unload. X-digital.com in San Diego and gwcopiers.com in Minnesota sell refurbs.
Toner is less expensive and you get automated registration adjustments with a V3100.
