Focus calibration
The Flextight scanner uses an adjustable zoom and focus mechanism to
optimize its scanning resolution for each of the original formats it can handle. If you
suspect your scans are not as sharp as they should be, then you may need to calibrate
your scanner. Note that you must not calibrate the scanner every day. It is intended
that the scanner is calibrated not more than once every three months. In most cases,
this procedure will never be necessary.
Use procedure below to make Focus Calibration:
1. Locate the Focus sheet that came with your scanner. It is a 8 x 9 cm (3” x 3.5”)
square of transparent black and white film.
2. Mount the film into the 6 x 6 original holder with the text reading normally as
shown. Place the sheet as straight as possible. Use the scanners light table grid and
the corners marked on the sheet to help align it.
3. Select Focus Calibration from the Maintenance menu.
4. Click on the Calibrate button, and the focus calibration starts.
5. When the focus calibration is finalized, you will get a message saying that the cali-
bration was succesfull. Click OK..
The scanner is now calibrated for all resolutions and for both transparent and
reflective originals.
