the service manual says to replace the main pcb before you do this try to upgrade firmware even if it is current or try a different ADF the DIMM could be the problem if the board has 1 try cleaning the contacts with an eraser welcome to Kyocera repair

what is the error message make sure the scanner is unlocked its the yellow slider on top left under the document feeder

I think the message is "Reseat All Originals in Document Processor". This message apears when there was a misfeed or something like that. It means that you must put back all the documents, to be scanned again. Clean the paper feed/pickup rollers with a cloth dampned in alcohol.

from the copy screen touch the duplex button on the display and choose 2 sided > 2 sided. if it is not available in the menu the duplex unit may have failed repeatedly and shut itself down in which case you would need to go into simulation mode and perform a u906.

umm if I understand correctly you want one document printed same document on both sides select double side printing the where it ask for how many copies you want send to or how many of the documents you want in increments of two ex. 2=1 double side copy,4=2 double sided ,6=3double sided

This message often shows up when the memory is full from one document (normally a large file) to fix it you have to add external memory

sorry but you haven`t duplex on your machine. you need to buy dublex unit or you can print on one side end insert the paper again and print on the other side.

Clean the glass near where the paper enter the glass
