Chapter 22-8-there will be indications of 'number', 'total', and 'division ID'.-'division ID' is a character string made up of the following: date of transmission, time of transmission, 0000 (fixed character string), transmission file number, hostname.-all units of the same mail will have the same ID'.ex:Content-Type: message/partial; number=1; total=3;id="20041110104508.0000.CanonTxNo.0105@e320g-43-1.ccm.canon.co.jp"(2)Page-Based Division TransmissionThe attached image data is divided with reference to page breaks within the 'transmission data size upper limit' specified in user mode, transmitting it by dividingit into multiple mails.If Multi Page TIFF or PDF is selected, multiple pages up to the specified upper limit will be transmitted as a single Multi Page TIFF or PDF file.If transmission is by collecting multiple files inside a Box, the transmission will be as a single job, increasing the possibility of its being divided.If the size of the attached image data for a single page is in excess of the setting, the transmission will be handled as an error, ending the ongoing transmission.If the setting is '0', no division of the data will occur, and all data will be transmitted as a single mail regardless of its size.Default maximum data size is 3MByte.Example of Divided Transmission for Multiple FilesWhen using PDF transmission of the following 3 files:-file A, consisting of 5 pages-file B, consisting of 6 pages-file C, consisting of 2 pagesIn keeping with the setting for divided transmission, the mail will be divided as follows, converted into PDF files, and transmitted as 3 mails:-mail 1, consisting of 1 through 5 pages of file A + 1st page of file B (as PDF file)-mail 2, consisting of 2 through 6 pages of file B + 1st page of file C (as PDF file)-mail 3, consisting of 2 pages of file C (as PDF file)F-2-72.1.10 E-Mail Divided Data Reception 0020-7905The following takes place in response to an incoming divided mail:The divided mail (message/partial) will be temporarily stored in 'divided data reception box' inside the System Box; once all divisions are available, merging isinitiated.As in the case of a normal mail, the result of merging will be printed, transferred, or stored in the System Box.If a length of time is specified for 'divided reception time-out', and such a time passes, as many divided mails as possible are merged and the result will be printedas soon as data is enough to make up a single page.If the data is not enough to make up a single page, such information as on To, From, and Subject provided as part of the main Header will be printed.A mail for which a time-out condition has occurred and mail units with the same ID will be removed, ending the job as an error (code #848).The mails that are stored in 'division data reception box' may be manually removed.If a check mark is put for 'print at time of deletion', an attempt for merging will be made, and printing occurs if possible. This operation will be identified by errorcode #99.2.1.11 USB Deactivation 0020-7906This feature sets permissions for using the USB device/host interface.USB Device On/OffWhen USB is connected with iR and PC is printed, it uses it with the USB device.iR rectangular connector on A side is done.This parameter is located under the System Settings. With this parameter, the USB device interface can be turned on or off (the factory preset is on).On: normal operationOff: both raw mode and USB's 1284.4 mode operations stopThe plug-and-play function is also disabled because the device does not respond to Device-ID requests.Changes to the on/off setting take effect the next time the device is restarted.USB Host On/OffWhen IC card reader etc. are connected with iR, it uses it with the USB host.It connects it with the flat type connector of iR.This parameter is located under the System Settings. With this parameter, the USB device interface can be turned on or off (the factory preset is on).On: normal operationOff: operation stopsThe plug-and-play function is also disabled because the device does not respond to Device-ID requests.Changes to the on/off setting take effect the next time the device is restarted.Note that this parameter is used to disable all devices that can be connected to the USB host, including IC cards and other authorization tokens, keyboards, andUSB keys.Location of ParametersUnder Additional Functions,
