Hi @Jeff1025, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
If your HP OfficeJet 5740 printer is displaying a paper jam error despite no visible paper jam and you've already cleaned the rollers with alcohol, try the following steps:

Power Cycle the Printer

• Turn off the printer and unplug it from power.
• Wait for at least 2–3 minutes to reset the internal sensors.
• Plug it back in and turn it on.

Check for Hidden Paper Bits

• Open all access doors (front, back, and ADF if applicable).
• Use a flashlight to look inside for small, torn paper pieces.
• Remove and reinsert the paper tray.

Manually Rotate the Rollers

• Turn the printer off and unplug it.
• Locate the rollers in the rear and front.
• Manually rotate them to ensure they are freely moving.
• If you feel resistance, a tiny paper piece may be stuck inside.

Reset the Printer

If the error persists:

• Press # and 3 while turning the printer on (partial reset).
• If this doesn’t work, try # and 6 (semi-full reset).
• If the issue persists, try # and 9 (full reset, but this erases settings).

Update the Firmware

• Go to HP Support and check for a firmware update for your model.
• Install the latest firmware update, as it may fix sensor-related issues.

Check the Paper Path Sensor

• If none of the above work, the issue may be with the paper path sensor (dirty or faulty).

I hope this helps. 

Take care and have a good day.
