It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.
1. Slide the guide tray unit while pressing the stopper in the arrow direction, and remove the guide tray unit.
5. Remove the drive arm concave phase from the tray slider and tray.
2. Raise the loading unit. 3. Slide the lever in the arrow direction till it stops and pull the tray out.
<Assembling the tray unit> 1. Insert a part of the tray into the unit sliding over the groove on the mechanical chassis unit. 2. Insert the tray to the point before the tab of the mechanical chassis unit.
4. Spread the tabs at the both sides and pull the tray out. (The tray slides a little forward and stops.)
3. Hook the drive arm concave phase over the tray and the tray slider. 4. Press in the tray. 15
