The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

I had been looking for a Manual for my CS2150 for quite a while -- in fact I had just about given up. I saw this site and decided to download the Manual. When I Received it by Email I was really pleased with what I got, with the result that My Kenwood 'Scope is now 100% repaired and working well. As an AV Serviceman, you need a good 'scope, and thanks to this site, and the Service Manual, I have been able to repair it. The Manual was a copy of the Factory Original and the copy was very clear, especially in the area of the Circuit Schematics, where You really need to be sure of what You are looking at.

I recently purchased a manual for a Samsung DLP tv to help with a trouble shooting problem I was having. Every tv repair shop wanted close to $400.00 for the fix, but after I found Owner-Manuals.com I hit pay dirt. The manual they had for me to purchase and download was a complete service manual for the exact tv I needed. It was complete with wiring diagrams, schematics, and even part numbers. If your the fix it yourself type I highly recommend trying to find any manual here before paying someone else to fix whatever problem your having.

Once again, excellent price and manual delivered in a timely manner and as advertised!
4 CIRCUIT OPERATIONS
4.1.
4.1.1.
FACSIMILE SECTION (for KX-FP80)
THERMAL HEAD
Please replace original Service Manual page 138 in the KX-FP80. (6.4.3.THERMAL HEAD) 2.Circuit Operation Refer to the block diagram and the timing chart on the following page. There are 9 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 192 heat-emitting registers. This means that one line is at a density of 192�9=1728 dots=(8 dots/mm). White/Black (white=0, black=1) data in one line increment is synchronized at IC501 pin 115 (THCLK), and sent from IC501 pin 114 (THDAT) to the shift register of the ICs. The shift registers of the 9 ICs are connected in series, and upon the shift of the 1728 dot increment, the shift register becomes filled with data, and a latch pulse is emitted to each IC from IC501 pin 118 (THLAT). With this latch pulse, all the contents of the shift registers are latched to the latch registers. Thereafter, through the addition of strobes from the IC501 pins (105, 106), only the dot location of black (=1) among latched data activates the driver, and the current passes to heat the emitting body to cause heat emission. Here, the two line strobes, STB1 to STB2, impress at intervals of 9.216 msec, as required for one-line printout. The sequence is shown on the next page. [Moreover, for the strobe width, the thermistor value inside the thermal head is detected according to IC501 pin 2. Depending on that value, the strobe width is recorded in ROM (IC502). Accordingly, the strobe width is determined.] When the thermal head is not used, the IC501 (23, THON) becomes low , Q501 turns OFF, IC506 turns OFF, and the +24V power supply for the thermal head driver is not impressed to protect the IC.
