I'm getting a "PLACE DOC. FEEDER IN DOWN POSITION" message when I place a document in Doc Feeder input tray of my Toshiba E-Studio 577 copier?

Check the connection of the doc feeder to the copier. if you open a cover on the doc feeder does reflect on the copier? Ensure the doc feeder is aligned there is a small magnet right front side of the doc feeder that sits on top of a switch (Can not be seen underneath front plastic the copier when down. Adjustment bolts for the doc feeder is the rear right hinge only.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

Hi,

90% it is the RADF PCB. Before replacing it check the sensors and switches of the RADF in 03 mode. Refer to page no 2-29 of SERVICE HAND BOOK.

problem with the feeder sensor >>top at the arrow

On the rear left side of the copier there should be a black hinged actuator sticking up out of a hole in the panel, directly opposite of that there should be a white plastic tab that pushes that actuator down. If not try taping the actuator down flat with the cover.

Check that the chord for the doc feed hasnt come out and that when you put document in the feeder the light comes on and it initialises the tray lift to the ready position it sounds as if the feeder connection is faulty and it is looking for document on the glass face to copy .. it doesnt see the document so it cant work the size out.

Something is blocking the Original Present sensor in the document feeder. The machine thinks you are trying to use the doc. feeder to make a copy. Clear the obstruction and this should remedy situation.

Hello sir; there have a document senser when you feed the document, check the senser may be it come off or broken.

power supply has the fuse open that feed the voltage for the ardf

When you lift/ open the ADF you should see a tab in the back corner (slightly in from the corner) of the ADF. This tab is for the machine to see that the ADF is closed. Make sure tab is there. On its sister model they used a depression switch, check that and make sure it is there and working properly.
