Correct Answer. B. Inspect the paper tray for proper alignment Misaligned paper trays can cause the printer to detect a jam even if no paper is stuck because it disrupts the normal paper path.
Option A is incorrect. Restarting the printer might temporarily clear the error, but it won't solve an underlying mechanical issue.
Option C is incorrect. Replacing sensors is more complex and typically not the first step unless there's evidence of sensor failure.
Option D is incorrect. While paper quality can affect functionality, it doesn't directly relate to the detection of non-existent jams.
