The UC-series UMAX scanners
often make problems. That may have to do with the firmware version. The first
firmware versions are not compatible with Windows95, so I think they will not
work with this driver too. UMAX suggests to use the following firmware versions
for Windows 95:
 
 
 
| Suggested firmware versions for old UMAX scanners |  
| Name | suggested firmware version (read on UMAX's german website)
 | last firmware version |  
| UC630 ### | 2.8 | 2.8 |  
| UC840 | 1.6 | 1.6 |  
| UC1200S | 2.5 | 2.5 |  
| UC1200SE | -- | 3.3 |  
| UC1260 | 1.6 | 1.6 |  
### The UC630 can not be upgraded if the last 4 digits of the serial number are less than 1000!
