I would not plug this machine in without finding a manual like this. In addition to setup and normal operating instructions, it has troubleshooting flowcharts, diagrammed mechanical adjustments, and schematics to beat the band. The tech I hand it to would be thrilled to find solder side PCB diagrams with component outlines superimposed, pinouts for every IC chip, and line drawings of transistors, with labeled legs.
As for printing quality, this may be a copy of a copy, but even the finest print when enlarged is very legible. There is a bit of grayed print over a few pages, as if a wet page were placed over it, but the print is still very legible. If you could borrow an original manual and get it printed and bound for 4 to 6 times the cost, you could get better quality. In that case you wouldn't be here. For price, utility, and availability I am rating this manual highly.
