How to Fix Error Code 61
-
Power Cycle the Printer
Always power off the printer completely before disconnecting any cables to avoid electrical damage. -
Check and Reseat the Multi-Bin Mailbox Accessory
Power off and unplug the printer before removing or reseating any accessories to avoid electrical shock or damage to the printer's logic board. -
Inspect for Paper Jams in the Mailbox
-
Clean the Mailbox Sensor
Do not use water or liquid cleaners near sensors or electronic components inside the printer or mailbox accessory. -
Update or Reinstall Printer Firmware and Drivers
-
Restore Printer to Factory Defaults
A factory reset will erase all custom configurations. Make note of your current settings (Wi-Fi passwords, IP address settings, etc.) before performing this step. -
Replace the Multi-Bin Mailbox Sensor
Disassembling the mailbox accessory may void the warranty on that component. If the printer or accessory is under warranty, contact HP support before attempting this repair.

When to Call a Professional
If you have completed all troubleshooting steps — including power cycling, reseating the mailbox accessory, clearing jams, cleaning the sensor, updating firmware, and performing a factory reset — and the error code 61 still appears, the internal sensor or mailbox logic board may have failed completely. Contact HP support or an authorized HP service technician for professional diagnosis and repair. You should also call a pro if your printer is still under warranty, if you notice burnt smells or visible damage to the mailbox connector, or if you are not comfortable disassembling printer accessories.Frequently Asked Questions
What does HP Printer Error Code 61 mean?
HP Printer Error Code 61 indicates a problem with the multi-bin mailbox sensor. This sensor detects paper in the output bins and routes print jobs correctly. The error is triggered when the sensor is dirty, stuck, misaligned, or has failed.
Can I use my HP printer while Error Code 61 is showing?
In most cases, Error Code 61 will prevent normal print job completion or cause output routing issues, meaning the printer cannot function correctly until the error is resolved. It is best to troubleshoot and fix the error before attempting to print.
Will a factory reset fix HP Printer Error Code 61?
A factory reset can resolve error code 61 if it was caused by a corrupted firmware state or software misconfiguration. However, if the cause is a physical sensor failure or paper jam, a factory reset alone will not fix it — you will also need to address the hardware issue.
How do I know if my HP mailbox sensor needs to be replaced?
If you have cleared all paper jams, cleaned the sensor, reseated the mailbox accessory, and updated the firmware but the error persists, it is likely the sensor has failed and needs replacement. A failed sensor flag that no longer moves freely or an optical sensor that is visibly damaged are also signs of a hardware failure.
Does HP Error Code 61 only appear on printers with a mailbox accessory?
Yes, Error Code 61 is specifically related to the multi-bin mailbox accessory. This accessory is an add-on component found on higher-end HP laser printers used in office environments. If your printer does not have a multi-bin mailbox accessory, you are unlikely to see this specific error code.
