I looked that error "6D" and could not find anything.
Although there is a error 6E that denotes a hardware problem with the machine.

Look where you put the paper in. See if you can see inside there and see the roller that turns and picks up the paper. If you can, make a mixture of alcohol and a little dish soap. Damp a rag with it, and reach in there to clean the rollers.  See if the rollers will turn manually, but be careful not to force anything.  Another way to get to the whole roller, would be to start making a print, while watching the rollers.  As soon as the rollers have turned half way, unplug the printer.  Now you can reach the other side and clean that.

There is another way to clean the rollers.  Using the alcohol mix, take a single sheet of paper, and damp one half of it with the solution.  Stick the single sheet in the paper tray, and make a print, but hold on to the paper so that it doesn't feed through the machine.  Do this several times, and the rollers turning against the wet paper should clean them.

Try to print again. It might take a few tries. The rollers have to turn against the paper and dry themselves off again.

If this works, then you need new rollers (cleaning them will only make them work temporarily and the problem will come more frequently until you change them).

Thankyou,

The only way to clear the toner low i believe is to change the toner.

Look at back of machine and at your new hinge, note the screw hole, if you undo both of those on the back of the printer, entire doc feed will come up and out, BECAREFULL just lift A LITTLE is enough to enable hinge base to be free of sockets (many cables attached) and place doc unit slightly sideways on copy glass to enable yourself access to 3 screws that hold hinge.
