How can I recalibrate my ScanJet 8250?
The user's manual that came with my ScanJet 8250 says nothing about
calibration. It's certainly possible that it does it automatically at some point of its own choosing, but I would be happier if I could tell it that "now" is the time. Does anyone know how to make this happen? And on a related topic, any ideas where I can get my hands on a service manual for this scanner? The hp site doesn't offer one. Thanks, Chris |

Not sure but most manufactures have manuals on their web site. Might try that.

Thanks, Chris Most scanners automatically recalibrate (for brightness and colour balance) every time they're asked to do a scan as brightness of the Cold cathode tubes can vary slightly each time they're turned on (LED scanners also calibrate to check the image sensor) - inside the casing at the head park position (or between park and the glass) there is a white strip that the scanner uses for calibration. If the white strip ever gets dirty then you'll get odd colour casts on the image (the scanner rebalances sensor levels to read the dirt as white). If you have any thin lines of wrong colour down the scan then this is more likely to be a speck of dust on the optics. |
