I needed a service manual as the display on my oscilloscope was very dim. I thought I'd give owner-manuals.com a try, as they advertised a huge number of manuals. Sure enough they had one listed. I bought it hoping it would be useful... actually, I bought it hoping it would be readable! I've had manuals from online sources in the past, and been very disappointed. Not this time! An excellent manual, complete, and very readable. Using it I fixed my 'scope, and as such the manual was an investment that paid off manyfold. Do I have any complaints? One very minor one - The circuit diagrams could have been scanned at a higher resolution, as some of the details were a little difficult to make out - not impossible, just not as easy as my old eyes would like! Overall, I'm very satisfied with my manual, and I will certainly be using this company again. Well done.

I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks

This is quiet a rare manual, I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, Excellent guide: very clear, enabling us to print readable diagram overall it is great to have this manual available for purchase. This is a complete service manual no pages are missing. Thanks

This SM is quiet scarce and hard to find it is an excellent Service manual, very clear to read and to print schematics and diagrams, Hi quality, Complete manual with no pages missing. I am very pleased with the manual and the fast service I have received. Great place to shop.
Good luck finding you manual...

Quick delivery, the document was usefull, although the copy was i little bit unclear in the details.
2.6 THERMAL HEAD POSITION ADJUSTMENT 2.6.1 Outline The mechanism is designed to be movable by about ±0.4 mm by means of the Head Arm and Heat Sink, and the Thermal Head position can be adjusted by means of the Heat Sink. As a result, an adjustment is required after the Heat Sink has been separated from the Head Arm. The Thermal Head is attached to the mechanism so that only a half of the mechanism can be disassembled unless the Heat Sink is separated from the Head Arm. The remaining half of the mechanism contains the motor and associated parts. Normal printing requires that the Thermal Head press the ink and paper against the optimum position on the Platen Roller. If for example the pressurized point is deviated obliquely, wave or wrinkle patterns will be observed on the print area and the colors become pale. Even when the parallelism of the Thermal Head is maintained, similar symptoms to the above may be observed when it is deviated upward or downward. The phenomenon described above occurs when the Thermal Head is not pressurized against the designated area on the Platen Roller with the designed pressure values being applied. Since the Platen Roller is a simply rotating part, the part to be re-positioned in this case is that of the Thermal Head alone. Assuming that the optimum position is A, Standard paper: A ± 0.25 mm (approx.) The �±� indicates tolerance and the Thermal Head is satisfactory if it is within that tolerance range. In the actual mechanism, the Thermal Head can be moved by about ± 0.4 mm.

2.6.2 Adjustment Procedure Assuming that 1 in Fig. 2-6-1 indicates optimum position A, normal printing may seem to be possible even when the position is deviated up or down like 2 or 3 or obliquely like 4 or 5. However, these figures show only the extreme cases. In actual operation, if the position is deviated as shown in 2, 3, 4 or 5, the deviation may exceed the tolerance. In addition, if it is assumed that 2 indicates optimum position A, cases 3, 4 and 5 exceed the acceptable tolerance and only 1 and 2 fall within it.
