Performing Operations on Document Server Documents (MFP models only) • From DeskTopBinder or Desk Top Editor For Production, it is possible to print out Document Server documents that were stored using the Copier, FAX and Scanner functions or those that were edited and then returned to the MFP from one of the two DeskTop applications mentioned above. Commands issued from these applications allow documents stored using the FAX function to be sent as FAX data, and those stored using the Scanner function to be forwarded to ScanRouter. In addition, it is also possible to download Document Server files from the MFP to the PC, make changes to the bibliographic information of these documents or delete the documents themselves, all from within DeskTopBinder or Desk Top Editor For Production. Documents stored using each principal machine function can be protected with a password. Users are prompted for this password, even when attempting to perform the above operations from inside DeskTopBinder or Desk Top Editor For Production. Restoring Files Back to the MFP (MFP models only) • When Copier or Printer files that were originally sent from the MFP to Desk Top Editor For Production in TIFF or JPEG format are then restored to the MFP, the data is saved to the HDD as a separate file from the original one. Viewing and Changing User Information Stored in the MFP/LP • User data stored in the MFP/LP can be captured, added to, deleted, and changed from inside SmartDeviceMonitor for Admin, however this requires User Administrator access rights. Viewing and Changing Machine Settings Stored in the MFP/LP • Some machine settings stored in the MFP/LP can be viewed and changed from inside Web SmartDeviceMonitor Professional IS. At present, it is possible to change a portion of the System Settings that can be changed from the MFP/LP operation panel, however these operations require authentication as a Machine Administrator, Network Administrator or User Administrator.

NetFile (GWWS)

2-5-1 Overview of NetFile Operations

•

NetFile operates via communication with the following applications installed on a network-connected

client PC:

DeskTopBinder, Desk Top Editor For Production, SmartDeviceMonitor for Admin, ScanRouter, Web

SmartDeviceMonitor Professional IS.

Performing Operations on Document Server Documents (MFP models only)

•

From DeskTopBinder or Desk Top Editor For Production, it is possible to print out Document Server

documents that were stored using the Copier, FAX and Scanner functions or those that were edited

and then returned to the MFP from one of the two DeskTop applications mentioned above. Commands

issued from these applications allow documents stored using the FAX function to be sent as FAX data,

and those stored using the Scanner function to be forwarded to ScanRouter. In addition, it is also

possible to download Document Server files from the MFP to the PC, make changes to the

bibliographic information of these documents or delete the documents themselves, all from within

DeskTopBinder or Desk Top Editor For Production.

Documents stored using each principal machine function can be protected with a password. Users are

prompted for this password, even when attempting to perform the above operations from inside

DeskTopBinder or Desk Top Editor For Production.

Restoring Files Back to the MFP (MFP models only)

•

When Copier or Printer files that were originally sent from the MFP to Desk Top Editor For Production

in TIFF or JPEG format are then restored to the MFP, the data is saved to the HDD as a separate file

from the original one.

Viewing and Changing User Information Stored in the MFP/LP

•

User data stored in the MFP/LP can be captured, added to, deleted, and changed from inside

SmartDeviceMonitor for Admin, however this requires User Administrator access rights.

Viewing and Changing Machine Settings Stored in the MFP/LP

•

Some machine settings stored in the MFP/LP can be viewed and changed from inside Web

SmartDeviceMonitor Professional IS. At present, it is possible to change a portion of the System

Settings that can be changed from the MFP/LP operation panel, however these operations require

authentication as a Machine Administrator, Network Administrator or User Administrator.
