have one at a pharmacy with 900k and threw the 111 code--30/34/35. hoping to remove printhead clean reassemble and move on. it did help me get past the code but guessing it needed more than that as it started to do bad printhead things like lines half blank page ets, all intermittently.sometimes streching print out enough that i get error that paper size not correct after job prints. i can delete remaining job and continue. given that manual says controller board for 111.3 i question maybe it is board or maybe board and lsu. gonna order a refurb lsu today from item inc but time counts here as they need the second printer asap and we cannot find printers easily these days-especially lexmarks. has anyone had similar issues and found cure? think it may need the board or both? thanks-- tuey
