3.1
External PSU model only.
161198 |
Fixes issue of
scaner timeout/freeze when trying to scan in greyscale or lineart mode (even after a
succesful preview). This problem only affects some Astra 1200S-C (external PSU model),
when used with the revised driver architecture of VistaScan 2.4.5 or later. Small
improvement to images in Quality mode through modified calibration-by-firmware routine.
Note: f/w 3.1 is also backwards-compatible with the older drivers, notably VS243. [source

3.0
External PSU model only. |
Solve the problem of scanner not reporting
"busy" to driver when chassis is still in motion (eg after preview, during
startup). [source TU98014] |
2.9
External PSU model only. |
Change to SER algorithm for improved
accuracy, improved SCSI comms, modify gain value for ERSO AD chip, modify AD adjustment
procedure to solve minor CIE (colour image error) issue. [source TU98007] |
2.7
191197 |
Add a second DC adjustment to solve problem
of Error Code 31, solves "image too light" problem with Toshiba CCD in tranny
mode, reduce motor noise and boot-up time. |
| 1.3 |
Improved calibration algorithm when scanner
is in Quality mode; improved shading curve accuracy; improved compatibility with Erso chip
to increase stability of starting up |
