IMPORTANT POINTS WHEN USING SCAN TO E-MAIL
Be careful not to send image data files that are too large.
Your mail server's system administrator may have placed a limit on the amount of data that can be sent in one e-mail
transmission. If this limit is exceeded, the e-mail will not be delivered to the recipient. Even if there is no limit and
your e-mail is successfully delivered, a large data file may take a long time to be received and place a heavy burden
on the recipient's network, depending on the recipient's network (Internet) connection environment.
If large image data files are repeatedly sent, the resulting burden on the network may slow down the speed of other,
unrelated data transmissions and in some cases, may even cause the mail server or network to go down.
The following table shows the approximate file sizes when the 8-1/2" x 11" (A4) size originals (one page each)
shown below are scanned.
* All sizes are for image files created in TIFF G4 format.
If multiple images are scanned, the file size will be approximately (Size of each image as indicated above) x (Number of images
scanned).
Although the actual limitation depends on your network environment, a general guideline for the maximum file size
for Scan to E-mail is 2000 KB (2 MB). In cases where you need to send multiple images in one transmission, try
such measures as lowering the resolution mode.
Original image samples
The original images shown below are samples to help you understand the above explanations. Note that these
images are smaller than the actual originals (the actual originals are 8-1/2" x 11" or A4).
Resolution
File size of text original A
when scanned
File size of photo original B when scanned
B/W Gray Color
75 dpi Approx. 10 KB Approx. 125 KB Approx. 140 KB
300 dpi Approx. 34 KB Approx. 1430 KB (approx. 1.43 MB) Approx. 1440 KB (approx. 1.44 MB)
The scan resolution will vary depending on the scanning area and how much memory in the machine is free.
During network scanning, the resolution may change automatically because enhancement is not performed. To
scan an A3 original in color at 600 dpi without enhancement, the 256 MB optional memory on the dual function
board and the 128 MB additional memory on the network expansion kit are required as a minimum.
