Vuescan and Epson 3170: freeze on Preview


B

Best

I'm trying out Vuescan 8.0.17 with Epson 3170 on Windows XP (SP 1). One
out of three times, the program freezes when its Preview button is
pressed. No movement from the scanner at all and the Program is listed
as "Not Responding" in Task Manager. It gets terminated as a result.
When I uses Epson Scan or scan from Photoshop with Epson Scan's twain
driver, nothing freezes at all. So is Vuescan buggy or what?

Vuescan is not buggy, not in my experience. There are a number of
different factors that may contribute to this.
What service pack SP2?
How many plug-ins and programs have you downloaded or are running in
the system tray?
It sounds as though the program is waiting for a response, the 'Not
Responding' is a timning based error.

I just bought a 3170 and Vuescan 8.0.17 does the same thing for me.
This seems to happen when the lamp in the scanner is warming up.
Apparently Vuescan goes into a loop or a wait state, but doesn't seem
to check to see if the scanner is ready again. I have downloaded
v8.1.4 and deleted the vuescan.ini file to see if that fixes it. If
not, I'll be writing to Ed to see if it's a known issue.

Just as a followup, Vuescan is still doing this. I upgraded to v8.1.4
and it still happens. It happens when I go away from scanning until
the scanner goes into standby (the lamp goes off) and then return.
When I try to start scanning again, I click the Preview or Scan button
in Vuescan and get the message "Warmup Lamp 1%" in the status bar.
Then that message goes away and Vuescan hangs. I have to kill and
restart Vuescan to get it to work again. Ed, is this a known issue?

To make sure whether it is VueScan or something else; How is the
scanner interfaced with the computer? If USB, can you try another
cable? Is it the only USB device connected? Try disconnecting as many
devices as possible, and then add them back one by one starting with
the scanner. Maybe there is a driver conflict with some other USB
device.

I have exactly the same problem with Vuescan (Epson's software works
correctly). I'm currently using v 8.0.10. I think it is a Vuescan bug. I
believe that Ed had some problems initially getting the 3170 to work
properly with Vuescan. Too bad because it is really annoying. He may be
using code that works correctly with other Epson scanners but not the 3170.

Just my 2 cents worth...

Ed Hamrick, are you checking for an ADF in the warm-up procedure or
trying to communicate with one with VueScan?

I downloaded and tried 8.1.4 as you suggested Ed, but the same result
obtains, that is, Vuescan is unable to bring the Epson 3170 out of standby
when you use the preview function. Vuescan reports "Warmup lamp...1%" until
I shut it down via Task Manager. I have to use the Task Manager because
Vuescan becomes, in Windows jargon, "Not Responding". Restarting Vuescan
eliminates the problem. Whatever your does to initialize the 3170 on program
startup works. Maybe you should use the same code to bring it out of
standby?

Just in case it matters, I'm using Windows XP Pro with SP2 applied (although
Vuescan behaves this way with SP1 as well). I'm not sure wheher this is
significant or not, but the grenn LED in the Start button of the 3170
flashes for a couple of minutes or so when Vuescan tries to bring it out of
standby but then the flashing ceases and it returns to a steady green
indicator.

Hope this helps,

Same result here, Ed. Looks like Vuescan goes into an endless loop
when waiting for the scanner to warm up after it had already been
working previously. Same parameters here... v8.1.4, WinXP SP2, USB
2.0 connection.

Same problem here.
I'am using Linux and can also use the Epson software: Iscan.
Have to kill Vuescan when it freezes.
I then start Iscan: no problem.
A subsequent start of Vuescan (after closing Iscan) is succesfull.
Did not have this problem with 8.0.? version.
Wish Idid not delete that

Mike, I have a zip file of v8.0.x if you'd like it. Just send me an
email and I'll replay back with the file attached.
