Problem:
- The printer works fine when powered on, but after it enters sleep mode, it becomes unresponsive.
- When attempting to print or scan after the printer has gone into sleep mode, the display remains blank, and the printer doesn't function. However, the power button remains lit, indicating the printer is still powered on.
- The printer is connected to a computer via USB.
- Navigation through the printer settings is difficult, even when the printer is awake and functioning. The display remains unresponsive or difficult to navigate, making it challenging to adjust settings such as sleep mode timeout.
Additional Details:
- The issue is specific to sleep mode, as the printer works immediately after being powered on but stops functioning once it goes into sleep mode.
- Once the printer wakes up, it is usable again, but navigating through settings (such as adjusting the sleep timeout or power settings) remains problematic.
- Attempts to adjust settings via the printer’s display are unsuccessful due to the unresponsiveness of the control panel during operation.
