Hi Guys.I have an irc 3380 intermittently jamming.Most of the jam codes are for 0D91(paper size mismatch).All the size indicator dials are set correctly and the copier will jam copying and printing.Also,when I go into service mode to look at the jams it doesn't show a diagram as to what sensor to look at.Is this normal for an 0D91 jam code?.The customer was using 75 gram paper so I got them to try 80 gram but as it is a 24 hour operation it is hard to monitor what they are using.I have ran hundreds of copys with the 80 gram with no problem.I cleaned any sensors I could find (including the pre-reg sensor).There is an internal finisher on this machine and I got a call today for finsher tray dropping and not returning to home position.I swapped the paper feed unit from tray 4 to tray 1 for the jamming problem just in case there was a problem with tray 1 but to no avail.Can the finisher on these machines throw up this sort of jam code.I'd appreciate any ideas you may have.Cheers!
