Miscellaneous problems

The client and server cannot communicate

If there is a firewall installed on the network, and the MarkVision Client and the MarkVision Server exist on opposite sides of the firewall, the client will not be able to communicate with the server. MVP will stop responding after the initial request. For the best results, only use an instance of the client that exists inside the firewall.

How do I increase the JVM maximum heap memory?

How do I increase the JVM maximum heap memory for systems managing a large number of devices and running the Job Statistics: Trend Analysis task?

The default maximum memory of the JVM running MarkVision Server is 512 MB. However, systems managing a large number of devices and running the Job Statistics: Trend Analysis task might need an additional allocation of maximum JVM heap memory.

How do I allocate the maximum JVM heap memory for my operating system?

For Windows operating systems:

  1. Stop the MarkVision Server.

  2. Open the registry editor by typing regedit in the command line.

  3. Navigate to:

    'HKEY_LOCAL_MACHINE --> SOFTWARE --> LEXMARK --> MarkVision Server --> Granite --> 1.0'

  4. Modify the key 'Jvm_Options' with value '-ms256M -mx1024M'.

  5. Close the registry editor, and then restart the MarkVision Server.

For UNIX, Linux, or Macintosh operating systems:

  1. Stop the MarkVision Server.

  2. Open the shell script '/usr/mv_pro/bin/MvService.sh', and then navigate to the function 'setJavaVars()'.

  3. Inside this function find the line the following line:

    JVM_ARGS="-ms256M -mx512M"

  4. Modify the line to say: JVM_ARGS="-ms256M -mx1024M".

  5. Save the shell script, and then restart the MarkVision Server.

No folders appear

If MVP does not display folders, and during log on a message indicates an error reading folders:

Make sure the MarkVision Server is running on the Web server

From the services control panel, verify that the MarkVision Server is running on the Web server. If it is not running, restart the service. If the service is running, ask the user to recreate their folders.


The file that stores your folders has been corrupted.

Contact the system administrator.

Cannot enter characters in printers in a different language

In some situations, a user may need to enter information in a printer in a different language than the MVP client is currently using. MVP has some limitations configuring or entering specific characters for devices in a language that MVP does not support. You must enter the characters manually, without using MVP.

Cannot send files to a device using Generic File Download

Printer Lockdown may be enabled. Because the Printer Lockdown task allows communication only over secure ports, it must be disabled to allow access to the FTP port required for Generic File Download.

To disable Printer Lockdown:

  1. From the MarkVision Professional Home screen, select Printer Lockdown from the All Tasks list.

  2. Select devices using the Quick Find or Folders tabs.

    Use Ctrl + click and Shift + click to select multiple devices.

    Note: When a device managed by MVP is not supported by a specific task, its name will appear with a black line through it in the Quick Find or Folders tabs. Password-protected network devices are displayed in red. Enter the device password to gain access to the device.
  3. Clear the Lockdown check box to remove lockdown from the device(s).

Cannot send files to network devices using Resource Management

Printer Lockdown may be enabled. Because the Printer Lockdown task allows communication only over secure ports, it must be disabled to allow access to the FTP port required for the Resource Management task.

To disable Printer Lockdown:

  1. From the MarkVision Professional Home screen, select Printer Lockdown from the All Tasks list.

  2. Select devices using the Quick Find or Folders tabs.

    Use Ctrl + click and Shift + click to select multiple devices.

    Note: When a device managed by MVP is not supported by a specific task, its name will appear with a black line through it in the Quick Find or Folders tabs. Password-protected network devices are displayed in red. Enter the device password to gain access to the device.
  3. Clear the Lockdown check box to remove lockdown from the device(s).

Cannot enter a PIN using the Operator Panel task

The operator panel screen will remain black while you are entering a PIN using the Operator Panel task in MVP. This is designed to avoid revealing the PIN on screen. The PIN will not register—and the screen will remain black—unless you press Enter on your computer keyboard or click button_select_0 on the remote operator panel.

To enter a PIN using the remote operator panel:

  1. From the MarkVision Professional Home screen, select Operator Panel from the All Tasks list.

  2. Select a device using the Quick Find or Folders tabs.

    Note: When a device managed by MVP is not supported by a specific task, its name will appear with a black line through it in the Quick Find or Folders tabs. Password-protected network devices are displayed in red. Enter the device password to gain access to the device.
  3. Select the PIN-protected function.

  4. Enter the appropriate PIN and press Enter on your computer keyboard, or click button_select_0 on the remote operator panel.

Cannot enter a PIN or password in RHEL 5.0

Because SCIM (Smart Common Input Method) is disabled by default in RHEL (Red Hat Enterprise Linux) 5.0, users must enable it in order to enter values into password and PIN fields in MVP.

Enabling SCIM in RHEL 5.0

  1. From the RHEL desktop, click System step Preferences step More Preferences step SCIM Input Method Setup.

  2. From the left pane, expand the FrontEnd menu, and then click Global Setup.

  3. In the Options section, clear the Embed Preedit String into Client Window check box.

  4. From the left pane, expand the Panel menu, and then click GTK.

  5. Clear all check boxes, and then click Apply.
