This service manual helped me to repair my PIONEER. Iam very satisfied, that I found it here.
Even the price of manual was not so high that person would not be able to spend a few money.
But that is very worth spent money. Thanks

Excellent quality service manual. Quick processing, fair prices. Love to do business again. Thank you!!!

Excellent service manual, the only known point of note is the alignment of improvability scanned pages within the pdf page. The resolution is good.

Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!
MultiPASS C530/C560 Chapter 2: Technical Reference
NOTE
Ink empty detection Ink empty detection during fax operation is performed by firing ink between the light source and receptor of the ink sensor, located on the left side of the printer. This function does not work with the BC-22e, only with BC-21e or BC-20. When ink passes between the source and the receptor, as shown in Figure 2-10, the sensor output will be a pulse waveform. The presence of ink may be determined from the pulse generation time. Ink empty detection is performed at the end of each received page of printing. If ink is not detected on the first detection attempt, the ink nozzle is shifted slightly, and the detection operation is repeated to double-check the first detection operation. If it is determined that there is ink remaining, the image data for that page will be erased from memory. If the cartridge is out of ink, the message �REPLACE CARTRIDGE� (with BC-20) �BLACK INK EMPTY�/�COLOR INK EMPTY� (with BC-21) will be displayed to inform the user that the cartridge is out of ink, and the page will be �received� to memory again from the image data. Method of Remaining Color Ink Detection The method for detection of remaining color ink is the same as that for the detection of remaining black ink. Sensor output is changed by passing each color (Cyan, Magenta, Yellow) in front of the ink sensor after the received image is printed. By counting the time of this change, the presence or absence of ink is detected. The sensor output also changes according to color, so the threshold value of the sensor is adjusted so that it can be reliably detected as normal. If one of the CMY colors is detected to be absent, "COLOR INK EMPTY" displays, informing the user that there is no more ink. When color ink has run out, the image is not printed as a BW image, no matter whether there is black ink available or not. The timing of the check for remaining volume of color ink is only either after the cartridge replacement button is pressed, or when a received image is automatically output. Also, when the BC-22e cartridge is being used, the check for remaining volume of color ink is not performed when copying is done, when PC printing is done, or in corresponding circumstances. The detection level of the ink detection sensor is adjusted automatically by means of a feedback circuit, and thus requires no manual adjustment. If the sensor output does not reach a standard level, even after performing feedback control (such as if the receptor is completely blocked, or if a sensor defect occurs), the ink sensor failure will be reported with the display of the �CHECK PRINTER� (error code ##348) message.
