# Pharos Station screen saver won't display

### Overview

The Pharos Station screen saver is separate from the standard Windows screen saver. This article explains how to troubleshoot the Pharos-native screen saver when it does not appear after the station remains idle.

### Symptoms

- The Pharos-native screen saver does not appear after the station remains idle.
- The station remains on the inactive or Welcome screen.
- Changing the Pharos screen-saver timeout does not resolve the issue.
- The screen saver works in Print Center mode but not in Legacy mode.
- A Windows screen saver appears, but the Pharos-native screen saver does not.

### Cause

Possible causes include:

- The station account or domain policy prevents Pharos Station from controlling screen-saver behavior.
- The `Screen Saver Period` registry value is missing, incorrect, or set to an unexpectedly long interval.
- On 64-bit Windows, Pharos Station may use the 32-bit registry path.
- Legacy mode uses an older station executable. Its idle-detection behavior on Windows 11 is not consistently reproducible and may require Technical Reviewer or L3 investigation.

### Resolution

1. Confirm whether the station is running in Legacy mode or Print Center mode. Do not troubleshoot the Windows screen saver as a substitute for the Pharos-native screen saver.

2. Review applicable Group Policy settings. Pharos Station must be able to control the screen-saver behavior. Check the following policies and set them to `Not Configured` if they are enforced for the workstation or organizational unit:

- `User Configuration > Administrative Templates > Control Panel > Personalization > Enable screen saver`
- `User Configuration > Administrative Templates > Control Panel > Personalization > Screen saver timeout`

3. Check the Pharos Station registry value:

- On a 32-bit operating system:

`HKEY_LOCAL_MACHINE\SOFTWARE\Pharos\Station`
- On a 64-bit operating system:

`HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Pharos\Station`
- Locate `Screen Saver Period`. Confirm that it is a `REG_DWORD` value and enter the desired timeout in seconds using Decimal format.

4. Restart the Pharos Station application after changing the registry value. Allow the station to remain idle for the configured period, then confirm whether the Pharos-native screen saver appears.

5. If the station uses Legacy mode on Windows 11 and the registry value has no effect, test Print Center mode where the required workflow permits it. Current documentation confirms that Print Center mode displays the Pharos screen saver after the Welcome screen remains inactive.

6. If Legacy mode is required, collect the Pharos Station version, Windows version and build, station mode, registry values, Group Policy results, and station logs. Escalate the case for Technical Review rather than treating the issue as a standard Windows screen-saver configuration problem.

**Notes**

- Do not assume that Windows 11 Legacy mode is production-validated for every Uniprint release.
- A `Screen Saver Period` value of `7200` seconds equals two hours and may make the screen saver appear unavailable during normal testing.
- Print Center mode does not support Reservation Station functionality. Use Legacy mode only when that workflow is required, and route Windows 11 compatibility concerns for Technical Review.
