I've been having immense problems with my newly acquired MP since installing and evaluating the latest Vuescan software which seemingly is responsible for throwing out my focusing.
I contacted Ed Hamrick and he suggested numerous actions for which I followed his instructions explicitly.
Not being totally computer articulate I was very deliberate in taking care and paying as much attention as possible. I would point out at this stage that I am a pensioner and on a learning curve, but I can read!
After a few unsuccessful attempts to remedy my problem this is Hamricks answer!
"I looked at the vuescan.log file again, and it doesn't contain the line:
**** Menu File | Default options
This means you didn't do this command.
Please stop wasting my time and don't send me any more e-mails. I'm
bored with sending you the same response, over and over.
Ed Hamrick "
I was shocked. I've only been emailing the man for 2 days and have sent 6 emails only! OK, it ain't fixed but despite what his damned log says I DID GO THROUGH MENU FILE / DEFAULTS a dozen plus times without success.
Shocking service and one to be aware of.
