We just worked on a customers Canon IR7095 for a E000840-001 problem. We had the faulty DC Controller repaired from Hytec and the machine is now copying. The copier is hooked into a Imagepass s1 print server. The print server sat for about a week left on. Prior to restarting the print server it had a lit display with no print on it and the indicator light above it was flashing amber. We've restarted it several times with no changes. Does the print server need to communicate with the copier before it will boot? Hytec did bring the board up to date with all Canon modifications. Do we need to update s1 software to function? I checked the image cntrllr setting on the copier and it is set to "4". Is there something I'm forgetting. Thanks in advance.
