Be very 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 images on the following page will produce the following file sizes when scanned as A4 (8-1/2" x 11") size
originals:

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. In cases where you need to send multiple documents, try such measures as lowering
the resolution mode.

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 A4 (8-1/2" x 11") size).

The name of the program category or particular item to be set will appear on the touch key. A touch of the key
will select the item displayed.
● Check mark boxes are touch keys that show the status of selections. A box with a check mark means the

function is "on" (enabled) and an unchecked box means the function is "off" (disabled). Alternate touches of
a box will change the on/off status.

If a program step requires more than one screen to display all available settings for a program step, 

 and 

arrow touch keys on the setting screens allow access to the available selections on all screens. If a selection is
accepted on one of the screens by a touch of the [OK] key, the display will return through the previous selection
screens within the same setting step to confirm the settings. After all settings are confirmed, the [OK] key must
be pushed again to advance to the next step.
The currently set numerical value is displayed.
Numerical values can be set by touching the 

 and 

 keys.

The setting programs for the network scanner feature of the machine are explained here.

The following programs are available:

You can select the initial display that appears when
you press the [IMAGE SEND] key to change to
scanner mode or when you press the [CA] key in
scanner mode. Normally the initial display is set to
the 

The following three selections are available:
● Condition setting screen
● Address directory (ABC)
● Address directory (Group)
When an address directory (ABC or Group) is
selected, the selected index of that address
directory (

) is set as the initial screen.

The number of one-touch keys displayed in each
address directory screen can be changed from 6
(the normal setting) to 4 or 9.
Touch [4], [6], or [9] to select the desired number.

These keys and indicator are

require the entry of numerical values.

NOTE
For the key name that appears in each one-touch
key, a maximum of 18 characters can appear when
the number of one-touch keys displayed is set to 4 or
6. A maximum of 10 characters can appear when the
number of one-touch keys displayed is set to 9. 

This is used to change the default resolution
setting for transmission in network scanner mode.
The default resolution is initially set to "LOWER".
To change the setting, touch the desired resolution

This program is used to set the volume of the beep
sound that informs you that the original has been
scanned. Two volume levels are available, or the
beep can be turned off.

If you do not select a sender when performing a
Scan to E-mail operation, the sender information
stored with this setting is automatically used. You
can check the stored sender information by printing
the SENDER list.

The sender name entry screen appears
Up to 20 characters can be entered.

Up to 64 characters can be entered.

The entered return address appears. Check the
address to make sure it is correct.

This setting selects the compression mode for
broadcasting using Scan to E-mail. The
compression mode set here is used for all
destinations regardless of their individual
compression mode settings. 
The initial settings are as follows:
● Black and white scanning: MMR (G4)
● Colour scanning: MIDDLE COMP

These programs are used to set the file format of
the transmitted image and the number of images
per file.
● The file type and compression mode is set in

"FILE FORMAT (FILE TYPE / COMPRESSION
MODE)". The setting takes effect in the following
situations:

• A file format is not selected when sending a

image.

• A file format setting was not included when the

destination was stored.

• If the file format is set when sending an image

or storing a destination, the settings apply to
the default file format settings.

● The "ONE PAGE PER FILE (YES/NO)" setting

is used to select how files are created when
multiple pages are scanned. Select "YES" to
have an individual file created for each scanned
page (so that multiple files are created). Select
"NO" to have all scanned pages combined into a
single file.

● The initial settings for the above programs are

as follows

• Black and white scanning

File type: PDF
Compression mode: MMR (G4)
One page per file: No

• Color scanning

File type: PDF
Compression mode: MIDDLE COMP
One page per file: No

To prevent the size of image files transmitted by
Scan to E-mail from becoming too large, you can
set a size limit.
If the size of the image file created by scanning the
original exceeds the limit, the image file is
discarded. The limit can be set from 1 MB to 10 MB
in increments of 1 MB. The initial setting is 2 MB.
The limit cannot be disabled.
