Has anyone used either the KirkRudy FireJet or the iJet Color Pro 1175 Pro. Have used PSI toner based machines over the past 6+ years. Have worn them out after 3 years and 3-4 million impressions. Done with the poor feeder and constant waiting to heat up. Looking to switch to inkjet. Print 1 to 1.2 million envelopes annually. Any information or review would be appreciated.
