They all have a CIS-sensor and can do up to 1200x2400 DPI. These models work fine with the driver. I believe, all hardware features are supported by the driver. Users of MP170, could you please confirm whether scanner buttons work with the stand-alone program? Run
./scan -B
and press a button. scan should print a number like "100" or "200". The first digit is the button number, "1" should be the "COLOR" button, "2" the "GRAY" button. The next two digits show the action you assigned to the corresponding button (See the table below for MP450 and MP800, thanks to Jose and Marcus). It would be nice if you could send me a list that shows which button return which value.

MP800 and MP800R (Basic scans should work but TPU doesn't work yet.)
MP800 and MP800R have a CCD-sensor and can scan 35mm negatives and slides up to 2400x4800 DPI. It uses the same protocol as MP150 and Co.
- Support for TPU (transparency unit) on request. I need usbsnoop log and, perhaps, a test device.
These models are new in Europe. MP530 has a CIS-sensor (1200x2400 DPI), MP830 a CCD-sensor (2400x4800 DPI). They both have an automatic document feeder (ADF). Ryan has reported that "simply changing the product ID to 1713 for the 500 printer in pixma_mp150.c enables the Canon Pixma MP830 just fine", thanks to Ryan. Therefore I assume that the both models use the same protocol as MP150 and Co.
- MP530 works fine.
- MP830: Single-side ADF should work. I'm working on duplex ADF. Many thanks to Klaus Wurmstein!
- What is the maximum width and height of the scannable area of MP730? You will see this information in Scangear, for example. I need width and height in pixels at 75 DPI and maybe at other resolutions in color and grayscale mode.
- How to properly cancel a scan operation? I need usbsnoop log for 2 cases: (1) scan and press the "CANCEL" button on the device, (2) scan and click cancel button in Scangear.
- How to control ADF of MP730?
- Can MP730 send button events to the computer? Test it with "
./scan -d 10 -B". Try pressing buttons on the scanner. Please send me a short description about which button produced what output.
- How to set gamma value? Is there a loadable gamme table?
- Does grayscale mode work for MP730?
- It seems that the hardware doesn't support grayscale mode. This has to be implemented in software.
- MP760 and MP780 still hang after one scan and I have no idea why it failed.
- The first scan works but subsequent scans don't work anymore. USB cable has to be replugged to let the scanner works again. Dan reported that his scanner (MP760) shows the "ready symbol" after the first scan. It seems that the scanner doesn't accept command from the computer.
- Why doesn't this happen to MP750? They all use the same protocol.
- Please try sane-backends-1.0.18. It uses libusb and has a difference initialization sequence. If it works, the problem is probably in usb.c and/or pixma_io.c. If it doesn't work as well, I'll open a bug for the backend. Please report the result!
- ...
- The scanner locks up sometimes. Similar problem as MP760 & Co.
- Please test button events with "
./scan -d 10 -B". Try pressing buttons on the scanner. Please send me a short description about which button produced what output.
