Brother MFC-J805DW unable-to-print-37 Error Fix

The Brother MFC-J805DW error unable-to-print-37 is a mechanical failure code resulting from the print head carriage getting stuck or hitting an obstacle. What does unable-to-print-37 mean on Brother printer? It means the printer's onboard sensors detected abnormal resistance during the head initialization, triggering a software lock to prevent motor damage. The MFC-J805DW relies on precise horizontal movement, and any debris can halt operations.

Common causes

  • 1Torn paper debris lodged inside the ink carriage track.
  • 2Excessive friction due to dried ink or debris on the guide rails.
  • 3Dirty encoder sensor ribbon preventing position tracking.
  • 4Internal belt tension issues caused by mechanical strain.

Solutions

Quick Diagnosis

If your printer stops immediately after startup, look for physical objects or shredded paper inside the carriage path. The error indicates the carriage is unable to move across its full length.

Step-by-Step Solution

  1. Unplug the device to ensure safety before reaching into the machine.
  2. Inspect the path under the print head for any paper bits.
  3. Manually slide the carriage to verify there is no unusual resistance.
  4. Power the printer on and let it reset its positional sensors.

Prevention and Maintenance

Keep the printer surface free of dust and avoid overloading the input tray. Ensure all ink cartridges are clicked securely into the ink reservoir tank to maintain stability.

When to Call a Technician

If clearing debris doesn't work, there could be internal damage to the carriage motor belt or the plastic gears that drive the print head mechanism.
