Nope not at all, scanning a log sheet is the same as faxing and can be an issue with a state DOT officer who wants to be an a**.
No matter who says what, the FMCSA has said the signature on the log has to be manually applied and not in any other form - this is from the FMCSA directly. The problem is FMCSA has not addressed the origin of the signature issue (this is again from them) and this is one reason why cut and past signatures are not allow for computerized logs - you have to have a sign copy in your records as a carrier, not a facsimile of that copy. Carbon copies are allowed because they are signed like the originals.
EOBRs step around the issue by having an established process for handling the data (that integrity word pops up a few times) and an assumption that the driver who he is which in reality can be a problem.
