Hi Mark,

first of all, we have a few questions:
- is there a printer attached to the scanner?
- are you using version 0.37 of the driver?
- can you send us the output of cat /proc/pt_drv/device0/info?
- is your parallelport switched to plain EPP mode in BIOS?

This problem is quite strange, because the ASI98001 based models
in general won't loose data.
