Plustek 7600i with Vuescan slow scanning

[ETW]

I've been using Plustek 7600i with Vuescan with no problems up until yesterday. Used to take about 30 seconds to scan. Now all the sudden 3-5 minutes per scan. I've restarted everything and no change. Any ideas? Running on Mac. 3600dpi color negative scan

Before I bought mine I few people commented that the scan times are unpredictable even if the settings remain the same. I'm finding that to be true. I'm using Silverfast 8, and the scan times make no sense to me. I can scan an image to get a baseline, and then scanning it with Multiple Exposure turned on is FASTER!

My own experience with my Plustek 7600i SE...

Sometimes scans are fast, sometimes very slow (same settings). If it starts scanning slowly, I cancel the scan and start the scan over. Usually this works, and the scan time is once again fast. I've had it take three or four cancellations before the speed increases. Once, I restarted the software (all using Silverfast 8) and it sped up.

No particular reason, it seems.

It occurs on my 7400. (Running on Mac mini 2009, both Mountain Lion & Snow Leopard)
Frequency of occurrence is rare, may be once a 50 or 100 times of power-on.

When it happens, I just power-off then power-on 7400 and restart VueScan.

Sounded like memory leak!!!

Happens with my 8100 too. Also when it scans REEAAALLY slow I get jaggy lines at 100% from the scans.

It has happened to me too sometimes (7400). Scanner restart is enough for cure but I recommend to see through the list of processes in Windows task manager (Ctrl-Alt+Del once) after shutting down the scanner. Sometimes the scanning software (quickscan.exe or something similar) needs to be shut down manually before restarting the scanner.

I've a 8200 with vuescan and mostly it scans incredibly fast @7200ppi (I scan my b/w without ME, so one single scan)
sometimes it scans really slow for no reason.

also you can't abort scanning! vuescan will not be able to scan correctly afterwards and often crashes. When I do abort accidentally I have to open silverfast and preview the frame several times and can then reopen vuescan.

Yep, whatever you do, don't abort a scan in Vuescan with a plustek.

Also I find certain DPI settings will cause the scanner to run super slow. At 3600dpi (my default) it scans a frame in about 6-7 seconds which is amazingly quick. At 4000dpi, it takes about 50 seconds. At 7000dpi it takes about 15 seconds. Go figure.

Hopefully the new 120 model will be bit more stable :-\
