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.

Symptoms in case of poor adjustment: Error efficiency deteriorated: 10 -3 (Optimum value: 10-4 or lower) High jitter of the RF signal RF waveform deformed Unstable operation in tracking closing and servo control Caution: Avoid exposing your eyes to laser beams for a long time. Preparation for adjustment: Clean both ends of the shafts. Use brand new skew screws supplied with the service kit GXX1234. Procedures: 1. Place the DVD mechanism module upside down. To avoid the disc from being robbed when it is turned upside down, first put a coin of about 1.5 mm on the table, then turn the disc upside down and set it so that the 1 in the figure comes to the point immediately above the coin. 2. After replacing the pickup (by referring to the procedures of "Removing the Pickup."), roughly adjust the three skew screws through visual check so that the pickup is mounted in parallel to the CRG chassis around the inner and outer tacks. 3. Connect an oscilloscope as shown in the connecting diagram. 4. Turn on the power of the product. Load the test disc (GGV1018). 5. In the front-end test mode, set the disc type to DVD layer 1. Then, turn on the power. Move the pickup toward the inner tracks. 6. Turn on the laser diodes. 7. With the focus servo closed, complete all automatic adjustments. Close the tracking servo, and then complete all automatic adjustments. 8 Follow the next procedures, from 8-1 to 8-5, and adjust the (three) skew screws. 8-1 Move the pickup toward the inner track and turn the skew adjustment screw C so that the RF level of oscilloscope becomes the maximum. (Tangential adjustment at the inner track position: Adjust the flatness of the disc at the inner track position with the adjustment screw C) 8-2 Move the pickup toward the outer track and turn the skew adjustment screw B so that the RF level becomes the maximum. (Tangential adjustment at the outer track position: Adjust the flatness of the disc at the outer track position with the adjustment screw B) 8-3 Leave the pickup at the outer track position and turn the skew adjustment screws A and B in the same direction alternately one quarter at a time (A�B�A�B ���) so that the RF level becomes the maximum. (Radial adjustment at the outer track position: Keeping the flatness at the outer track position, adjust the flatness of the whole disk with the adjustment screws A and B) 8-4 Move the pickup toward the inner track and turn the skew adjustment screw C so that the RF level becomes the maximum. (Tangential adjustment at the inner track position: Adjust the flatness of the disc at the inner track position with the djustment screw C) 8-5 Repeat the steps from 8-2 to 8-4 three times, and adjust at the position where the RF level becomes the maximum. 9. Turn off the power in the test mode. After confirming that the disc has stopped, eject the disc. 10. Adjust with a screw rock the shaft and skew adjustment screw to the same state as initial one.
