After installing a new multifunctional printer, an administrator realizes the flatbed scanner does not scan any documents. Which of the following is the MOST likely reason of the issue?

Flatbed scanners ship with a transport lock switch that physically secures the scan head to prevent damage during shipping. If the administrator forgot to unlock this switch after installation, the motor cannot move the scan head, causing complete scan failure. This is the most common and likely cause when a scanner produces no output immediately after unboxing.

An incorrect printer driver would more likely affect printing functions, not specifically isolate the scanner portion of a multifunction device.

Plugging the USB into an incorrect port would typically prevent the entire device from being recognized, not just the scanner component.

Alignment and calibration issues cause poor scan quality or skewed images, not a complete inability to scan any documents.
