Frequently asked questions – Scan to Network

FAQ Answer
Is Scan to Network a Microsoft Windows-only application?

Yes, if you are using a network shared folder via Server Message Block (SMB) protocol. But if you are using File Transfer Protocol (FTP) configurations, it will include other operating system environments.

Note: For the latest information regarding operating system compatibility, please consult the ReadMe file included in the application download file.

What version of the SMB protocol is supported by Scan to Network?

Scan to Network version 4.x.x relies on the firmware platform for the SMB protocol. The firmware platform contains an SMB client that provides all of the protocol support; i.e., eSF 2.x and eSF 3.x MFPs offer SMB v1 protocol, while eSF 4.x MFPs offer SMB v1 and SMB v2 protocol.

Can you use the Active Directory (AD) attribute of "homeDirectory" to map the directory in Scan to Network? Yes
Are there limitations to the length of the share path or depth of the shared file directory structure? No, the only limit is the one imposed by the target operating system.
Does Scan to Network have support for Distributed File Shares (DFS)?

Currently, only the following Microsoft Windows Server 2003 DFS environments are supported (additional support is being considered).

  • Stand-alone DFS
  • Domain-based DFS
  • Domain-based DFS with one child domain used for authentication.
What is the maximum number of destinations for Scan to Network? Scan to Network version 4.8.2 (and earlier) have a maximum of 30 destinations. Versions beyond version 4.8.2 will support up to 100 destinations.
Can each destination have its own unique authentication to the shared folder? Yes
Is it possible to prevent changing scan settings for a destination? Yes, Scan to Network allows administrators to disable the scan settings screen, thus, preventing you from changing settings.
Can Scan to Network work with a magnetic stripe, proximity or smart card badge authentication? If the Lexmark printer is equipped with magnetic stripe, proximity or smart card reader and the MFP has been configured to use it, Scan to Network can be configured to work with the badge authentication system.
How can you share a list of configured destinations with Scan to Network on other MFPs?

Scan to Network provides the ability to export all settings, including destinations to a Universal Configuration File (UCF). If you configure destinations on one MFP and export the UCF file, then you can import the UCF on all other Lexmark MFPs running Scan to Network.

To do so, go to the printer's Embedded Web Server (EWS) > Settings Embedded Solutions or Device Solutions > Solutions (eSF) or Apps > Apps Management Scan to Network, and then click Export found on the lower-left of the page (e.g., scanToNet.ucf).

Note: Authentication credentials are not exported and must be configured on each MFP.

Does Scan to Network support NT LAN Manager (NTLM) authentication? Yes
Does Scan to Network support Kerberos authentication?


Note: Authentication is dependent on MFP security settings.

Is it possible to disable the XML file which accompanies the scanned image file? Yes, this option is selectable in the printer's EWS.
When Scan to Network transmits the scanned image from the MFP to the shared network folder, does it stream the file or write the file to a folder all at once?

Scan to Network version 4.x.x will stream the file to the destination folder, one page at a time if the Lexmark MFP does not have a hard disk drive (HDD).

However, if the MFP has an HDD, the app will scan the documents and write them to the built-in MFP HDD. Once the entire document is written to the HDD, the MFP will write the file to the destination folder.

Why does the app pause sometimes after selecting the destination? When selecting a destination, Scan to Network attempts to access the shared network folder. On some networks, the folder authentication process can be slow, which results in Scan to Network pausing after selecting the destination.
What happens when scanning a large job on an MFP with HDD, complete job scans to the HDD, and then the MFP loses authentication with the destination folder?

Normally, the MFP would not lose authentication with the destination folder unless the network infrastructure or network server experiences an issue.

If authentication is lost, the MFP would lose the job on the HDD. The app provides no way to recover from such a critical infrastructure problem.

What happens if you scan a document on a Lexmark MFP containing an HDD, the entire job gets written to the HDD, and then the MFP loses power? If power is lost after scanning the job to the MFP HDD, the job would be lost. The app has no ability to resume operations after a power outage. In this scenario, you must scan the entire job again.
Does Scan to Network provide a status notification when the scan job completes?

Three notification options are available in Scan to Network:

  1. Control Panel Notification
  2. Printed notification
  3. E-mail notification

Note: All three notifications may be enabled simultaneously. The E-mail notification can only be sent to a static e-mail destination.

Why does the status notification occur prior to the image file being written to the destination folder?

Scan to Network version 4.x.x added support for background processing when choosing an Optical Character Recognition (OCR) or Highly-Compressed PDF file type. With the addition of background processing, the app hands the scanned image off to the background processing service and sends the status notification.

Note: The app has no ability to monitor the status of the job after it has been added to the background queue.

Does the status notification indicate a file has been written to the shared folder? The status notification does not indicate the image file has been written to the destination folder.
If a server is busy and the file cannot be written to a folder, does Scan to Network retry? Scan to Network has no retry algorithm. If a file cannot be written to a folder and the notification feature enabled, the MFP will send a failure notification when the file cannot be written to the shared folder.
Why does Scan to Network display "unlicensed" in the printer's EWS? The Scan to Network app does not require a license to work. If the app has a license status of "unlicensed", the Premium features are not available.
Can you add a license to Scan to Network?

Yes. When you add a license, you enable the Premium features.

Note: The licensed version of the Scan to Network app is called "Scan to Network Premium".

How can you purchase the Scan to Network Premium version?

You can obtain the license upgrade via your Lexmark Sales or System Engineering teams.

All other inquiries regarding the purchase of Scan to Network Premium must be made through dealer partners, or by contacting Lexmark Technical Support for more information.

Is there a document that lists out the additional features to the Scan to Network Premium version? Yes. See Document ID: FA707 for an article that highlights most of the differences.
Why does Scan to Network indicate a Hard Disk Drive (HDD) is optional? Most function in Scan to Network does not require an HDD. However, if an HDD is present in the MFP, Scan to Network will use the drive. Some additional features become available when the HDD is present including a first page document preview, and scanning pages directly to the HDD.
When you use a folder monitoring process to automatically monitor a shared folder and import files into their core business system, occasionally some scanned image files will not open. Why does that happen?

Older versions of Scan to Network wrote the scanned image directly to the shared folder using the final file name. If the file was partially written to the destination folder when the "file sweep" activity occurred, it could pick up an incomplete image file.

Scan to Network version 4.x.x and later write images to a temporary (.tmp) file format before copying the file to the final file name. By using the temporary file format, it prevents "file sweepers" from picking up partially written files.

When installed on a MFP with an HDD, does Scan to Network leave old files on the HDD after writing the images to the destination folder? All files written to the MFP HDD are marked for deletion after successfully writing the file to the destination folder. If disk wiping is enabled, the memory location on the HDD where the files previously resided will be overwritten to change all data from the original files.
When selecting an OCR output file (i.e. Searchable PDF, RTF, TXT) on an MFP containing an HDD, what operations occur and in what order to write the scanned image to the shared folder?

Scan to Network performs the following operations when creating an OCR file type:

  1. Scans images to the MFP hard disk.
  2. Performs OCR operation.
  3.  Writes file to shared folder.


Frequently asked questions – Bar Code Discovery

FAQ Answer
Is Bar Code Discovery part of the Scan to Network application? Bar Code Discovery is another application entirely unto itself. It is not included with Scan to Network Folder.
After you create a bar code template using Bar Code Discovery, can the template be loaded to other Scan to Network installs via MarkVision Enterprise (MVE)?

Yes, but only for SNF versions 3.1.0 and above. For this to work, you have to install Bar Code Discovery's read component software on the device and create a template.

Afterwards, you will export the SNF settings (UCF), and then use MVE to push that file down to any other devices that you wish to have the template data.
