Question about Canon DR-9080C Path-Through Scanner
Cannon DR-9080C Scanned to Pc Volume Problems I have a problem with this scanner. Scanning grayscale at 300dpi after 9 pages the scanner will pause for 10-11 seconds. Considering it takes about 3 seconds to scan 9 pages and the pause time is 10-11 seconds the downtime is quite considerable. Also i am unable to scan an a4 colour image at 600dpi. Or scanning a few a4 24bit colour image at 300dpi after about 6 the pc just takes soo very long to transfer from scanner to pc. I have 504 megs of ram and a 2.26 gig pent 4 . Now i presume i need more ram and or chipset power. What kind of specs do i need to run to get proper usage out of my scanner and not be bottle-necked. PS: The minimum requirement specs on this scanner are so far off par!
Hello We have been having this same problem when scanning Black and White as well. We have just played around and have changed one of our settings that has seemed to solved the problem for now. Try Properties (on scan settings) then more then click on - Detect Page Size - Image Width instead of Guide Plates Hope this works for you to

Check your scanning software settings for a "pre-scan cache" or for a "scan ahead" setting. Turning these on will usually eliminate the delay. Without a prescan cache, the computer will stop the scanning when its buffers are full, then give the OK to scan when the image processing is completed.

Upto the first 8-9 pages, the data sent by the scanner is in the RAM of yr comp. ONce it is full, scanner cannot send more data and hence the delay. There is something called 'ack' (Acknowledgement) between scanner & computer. Try storing data in JPG format, by changing the settings. This will speed up scanning. Canon 9080C can give you JPG outputs comfortably. Pls note there is some quality drop in JPG As compared to TIFF format. IT depends upon your end use application.
Color at 600 dpi will be a huge file. i.e, 600 x 600 x (8x8x8) for thre colors only for 1 square inch, above 180MB of data.Check if you really need that kind of resolution. Normally printed page is about 150 dpi only and scanning in high resolution does not improve quality, but only increases size.
