Howtek 4500 calibration issue

[onnect17]

Has any Howtek 4500 user come across the following warning which appears when the scanner is going through it's pre scan calibration proceedure "calibrating.... check lumens" or that might be insufficient lumens. The scanner stays in this mode until the scan is cancelled, there are no other available menu options accessible at this point. I have checked both lamps and can see no problems, the scanner hasn't been used for some time but was fine last time it was used.

It would help if you start allowing private messages.

I have some badly copied pages as pdfs, putting it up now. Here's the link-

Thank you so very much Tyler. You are a godsend. As a matter of fact the copies are damn good. This would be extremely helpful as I am about to embark resurrecting an Howtek 4500.. My sincere thanks again.

Just stumbled onto this--I'm having similar problems with my 4500--is that service manual still floating around?

I don't remember where I got them, pretty sure someone on the ScanHi-End Yahoo forum sent them to me long ago.
I tried to upload it at the forum so it would be available for anyone any time in the files section, but it exceeds their size limit. Also, I put the utilities there.You'll have to join, I think, to get it. But it's the best source for drum scanning info and mutual support anywhere.
