Scanner Testing

Scanner testing is done at the scanner testing station in printerland.

The test computer set up there has both standard and development scanner backends.

USB

 * 1) Select a scanner
 * 2) Locate a suitable power supply
 * 3) **Most scanners use a 12V 1.25A positive center power supply, but there are many exceptions.
 * 4) Plug into the USB port of the computer and power up the scanner
 * 5) Start xsane
 * 6) If xsane does not find any devices, wait a minute and try again (sometimes the scanner needs to warm up first)
 * 7) If xsane does find a device, it will open a preview pane. Put in an image to scan.
 * 8) Preview and then scan the image.
 * 9) Look for color variations, wavy lines, empty scan lines.

If the scanner fails at any point, record the number and put the scanner in the CBM bin
