Start Button Issues After Paper Jams
One prevalent issue users encounter with the HP LaserJet 4345x MFP is the start button light becoming fixed at orange following a paper jam in the Automatic Document Feeder (ADF). This behavior can signal that the printer is in an error state, often requiring users to clear the paper jam and restart the printer to resolve the issue. It is essential to check for any debris obstructing the paper path, as incomplete removal of paper can lead to recurring jams.

Settings Resetting After Sleep Mode
Another common frustration occurs when the “light/dark” settings for both copying and scanning reset to their lightest configuration after the printer wakes from sleep mode. This situation can be inconvenient, particularly when users expect their previous settings to remain intact. To mitigate this issue, it may be advisable to adjust settings through the printer’s software interface or explore firmware updates that could stabilize this functionality.

Scanner Initialization Problems
Users may also face a challenging scenario where the scanner fails to initialize, often indicated by an amber orange light on the printer. This issue could stem from faulty hardware components, including the formatter board or the scanner board itself. When this occurs, thorough examinations of these components or professional servicing may be necessary to restore functionality.

Control Panel and Firmware Challenges
Blank or hung display screens on the control panel are additional concerns that can occur with this model. Users experiencing this issue should first attempt a cold reset by pressing the ‘3’ button several times until “COLD RESET” appears on the display. If the problem persists, it may indicate deeper firmware issues that would require a restart or, in some cases, assistance from HP support to troubleshoot effectively.
