Sir, It is the document feeder, the Di620 is a very old MINOLTA machine, but you mite find a (NOW) Konica Minolta dealership that can update the document feeder EPROM (Erasable Program able Read Only Memory) chip located on the document feeder control board. It has to have its program updated to correct this problem which gives this code. Let them know you have the Technical Bulletin # 2617b they will not be able to call it up but mite be able to contact some one at Konica Minolta tech support that can get access to very old MINOLTA technical bulletins. Additional info is Knowledge Base # TAUS0645133EN00. Then will have to hope that Konica Minolta has keep the Firmware for the chip????? Maybe in JAPAN!!!!!!!!!. YOUR ASKING ALOT TO GET THIS MACHINE TO RUN!!!!

SOURCE: DI-450 C-143E

This is originally caused by 'stuff' being stacked on top of the document feeder. When the tray tried to raise the originals into position to feed through the scanner, it is held down by the rear paper guide hitting the stack of 'stuff'. Do this often enough and the release mechanism that prevents damage to the gears and motors gets worn or damaged.

Opening and closing the front door of the copier will reset the error message. If the error reoccurs for no apparent reason, then the tray lift mechanism needs to be serviced. This takes about an hour for a tech to perform.

There is one fix the user might be able to apply. There is a metal tab that sticks out the front of the document tray. When the tray is lifted, the tension on this tab is released. This tab is what applies tension to the internal lift gears for the tray lift. If you can 'adjust' this tab to cause more tension to be applied when the tray is dropped back to its normal position, this might be enough to not get any more C-143E's under normal conditions. Caution is called for as the assembly will not survive any rough handling.

Document in ADF


None of these worked for me. Here is my FIX:
Open the part containing the rollers. You can see a white plastic part which stop the documents feeded into the adf. Lower this part and insert a page into the adf just a bit further than where it would have stopped from that white stopper. This forces the machine to feed the document and clears the error right away. You only have to do this once and from then mine worked fine.
