Nikon-LS2000 Stage Loading Screw Error

[Larry Korenchan]

I just recently started to get a pop up message "Stage Loading Screw still
in place. Please remove it."

The screw is definately removed, but this pop up is causing a lot of grief
and I can't figure how to get around it.

Any suggestions? Is there a switch or sensor inside that may have failed or
dirty causing this erroroneous message?

I don't know about LS-2000 but a very similar LS-30 had *two* storage
screws. Could that be it?

Don't think so. I have been scanning slides for a while until this popped
up. If there was any transport screws engaged, the scanner won't scan....
I know I'm getting a false report from the scanner/software for unknown
reasons.

Perhaps too much load on the motor (high current) ? I think there were a
one or two cases listed in this newgroup of the drive screw binding
slightly caused by a plastic piece splitting or coming loose in the
screw holder. Have you moved the scanner recently ? You could try
turning it on it's side . Opening the case carefully should allow you to
inspect the screw and its holddowns. Look for the dust cleaning thread
here for a link. Another possibility is a flaky scsi cable or other
device on the scsi bus. Any changes there ?

Oh, I see. It's is an intermittent problem (spurious error). I thought
you couldn't scan at all.

In that case, Frank had a few good ideas. One way to narrow the
problem down is by the process of elimination i.e. ruling out one
thing at a time. If you made any changes lately, software or hardware,
try to backtrack.

Also, you may want to wiggle all the connectors and - in the olden
days (before my notebook) - I would open up my desktop for preventive
maintenance every few months to vacuum the dust and push all the cards
back in place. A nice, juicy "crunch" usually meant they wiggled out
due to temperature changes.

I did an internal inspection of the scanner and found the focus stage bound
up because it traveled to the extreme towards the servo motor that moves it.
By manually operating the servo shaft (turns the focus lead screw), the
problem was cleared, but came back later- jammed the same way. I can't tell
how the focus stage assembly determines end of travel has been reached
(limit switch, optical sensor, ?).

Any suggestions? Does anyone have a service manual for the LS-2000?

There has to be a limit switch of some kind, mechanical or optical.
