    Difference in file sizes between Kyocera and Ricoh

    Greetings All

    I am working on a scanning issue. we replaced a Ricoh MP5000 with a Kyocera 6501i. all the setting are the same 400x400 dpi, text mode, pdf.


    For the same scan, the file from the ricoh is about 38MB but the Kyocera ends up at 77MB. I know that there can be a variation between the two manufacture, but 40MB difference?


    would appreciate any feed back

    Thanks

      Re: Difference in file sizes between Kyocera and Ricoh

      Is one monochrome scanning, and the other color scanning? How about PDF compression rate? =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          Both are set to B/W text. Compression is set to TIFF v6 on the Kyocera and modified Hoffman on the Ricoh.

          Tried changing the compression, it change the size maybe 1 to 1.5MB.

              TIFF6.pdf

              TIFF 6 is an image file format which I thought was losseless, but it turns out it does have data compression options.
              However, the TIFF format has caused larger sized files whenever I have used it, so see if there is another option.

                  All Kyocera's come defaulted to color scanning, low PDF compression, 300x300 dpi. Changing the defaults to either B/W scan or auto and upping the compression will greatly reduce the file size. A color scan will be storing eight times the data [8-bit color depth on a Kyocera] per pixel plus the two bits of control info. If the Ricoh was scanning in black & white and you are scanning in color on the Kyocera this would account for the file size difference.

                      If you are doing OCR, you need a MINIMUM of 300 DPI!....if not doing OCR, and just visual text, set to 200 DPI (unless the text is REALLY small!), medium compression, B&W, Multi-Page PDF. That should take care of it for you!

                          Thanks guys for the reply

                          I was trying to compare as much as possible the same settings on both machines. the only difference I saw on the images is that the Ricoh was a lot more stark then the Kyocera. what I mean by that is that the Kyocera, although was set to BW text still has some almost grayish area in thing like graphs and images in the document. the Ricoh however did not have a lot of variation. very little gray if any.

                          Thanks again guys for the reply
