An office printer used for high-volume printing has been reported for improperly performing its finishing tasks. After sending a print job that included stapling, the pages come out unstapled and a staple jam error is displayed. You've already checked that the correct paper size is loaded, and the printer indicates sufficient staple cartridges. What should be your next step in troubleshooting this problem?
Restart the printer to reset the stapling mechanism functions.
Check the power source to ensure suitable power is supplied for stapling.
Inspect and clear the stapling unit for any jams or alignment issues.
Replace the network cable to ensure the finishing instructions are received properly.
