This is the code I got when I tried to install new developer and run L-detect. The L-detect came up with a 005 number and the machine when I rebooted came up with the F26-1 code. I have a helacious grinding noise coming from the toner supply section,and I can't find a new section like this. On precision roller they sell 3 different gears to repair it,but these are out of stock and are obsolete. Any konica people out there? is this a good repair option on this old machine or should the customer look at getting another machine. Is this toner supply section A hard repair job or a realitivly an easy job. PLEASE LET ME KNOW. Thank you. Anyone have a blow-up of the service or parts manual so I can see the parts involved Thanks again
