Scanner Testing
Revision as of 17:42, 18 June 2005 by MichaelWestwind (talk | contribs)
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
- Select a scanner
- Locate a suitable power supply
- Most scanners use a 12V 1.25A positive center power supply, but there are many exceptions.
- Plug into the USB port of the computer and power up the scanner
- Start xsane
- If xsane does not find any devices, wait a minute and try again (sometimes the scanner needs to warm up first)
- If xsane does find a device, it will open a preview pane. Put in an image to scan.
- Preview and then scan the image.
- 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
