Here is a good one. BW scanning is no problem, but as soon as a color scan job makes it through the document feeder a message pops up saying a file size limit has been exceeded. The only toggle for this is pertaining to email scans, and this machine will throw the message even when going SMB. There should be no limit. Two factors: This seems to have popped up when the main PCB was changed for an unrelated reason, but the board repairer is saying it shouldn't be his board. Also the machine won't take an RCON package. The read section goes through the main board via a PCI card and interface board. When something gets weird after a board change, probably that board. Board repairer wants the board back to look at it, leaving my machine down. I'd love to find another way out...
