Brother Error Print Unable 57 — What It Means & How to Fix It
Updated August 2026 · Independent PrinterCare USA support guide
The Print Unable 57 error on Brother printers is frustrating because it completely blocks printing until resolved, but the good news is that most cases involve simple paper jams that you can fix yourself in under ten minutes. This error specifically signals that the duplex unit—the mechanism responsible for automatically flipping pages to print on both sides—has detected an obstruction or mechanical problem.
Whether you're running a small office or printing from home, this guide walks you through the exact steps Brother technicians use to clear this error, starting with the safest and easiest fixes before moving to more involved troubleshooting. Most users resolve this without any parts replacement.
How to fix it — step by step
- Power down and unplug the printer completely. Turn off the printer using the power button, wait thirty seconds, and then unplug the power cable from the wall outlet. This clears the printer's memory and allows the duplex unit to reset safely without power running through it while you work. Leave it unplugged for at least one full minute before proceeding.
- Open the rear access panel and inspect the duplex unit. Locate the duplex unit on the back left side of your Brother printer—it looks like a gray plastic assembly with a fold-down or removable cover. Gently open or remove this panel according to your specific Brother model and shine a flashlight inside to look for crumpled paper, torn pieces, or plastic debris blocking the paper path.
- Manually remove all visible paper and debris. Using needle-nose pliers or tweezers, carefully extract any paper scraps, torn fibers, or foreign objects from inside the duplex unit. Be gentle to avoid damaging the small gears and sensors inside, and do not force any parts. Remove anything obstructing the paper pathway, including dust buildup that may have accumulated over time.
- Check the duplex unit flapper and drive shaft for damage. While the panel is open, look for the small plastic flapper arm that guides paper into the duplex path—it should move freely without resistance. Inspect the drive shaft for bent or cracked components, and verify that no screws have come loose. If you see obvious mechanical damage like a cracked flapper, the duplex unit will need replacement.
- Reseat the duplex unit and close all panels securely. Reinstall the duplex unit access panel, making sure it seats completely and any latches or clips lock into place. Close the rear panel and any other access panels you opened, ensuring everything clicks firmly. A loose panel can trigger the same error again, so verify that nothing is hanging open before proceeding.
- Plug in and perform a power cycle reset. Plug the printer back into the wall outlet and press the power button to turn it on. Allow the printer to complete its startup sequence, which typically takes thirty to forty-five seconds. Watch the display panel and listen for any unusual sounds that might indicate the duplex unit is still obstructed.
- Clear the error from the display and test with a print job. Once the printer finishes booting, the error code may still show on the display—press the OK or Clear button to dismiss it. Send a small test print job from your computer using a single-sided document first, then try a duplex print job (two-sided) to confirm the duplex unit is functioning. If the error returns, the duplex unit assembly likely requires professional service or replacement.
- Contact Brother support or use remote diagnostics if the error persists. If Print Unable 57 continues after clearing debris and resetting, the duplex motor or sensor may be faulty and require professional repair. Brother offers remote diagnostic services for around forty-nine dollars that can pinpoint internal mechanical failures and arrange next-step repairs or unit replacement through authorized service centers.

Frequently asked questions
Can I print single-sided documents while the duplex unit is broken?
Yes, in most cases you can print single-sided documents even with a duplex jam, because the error typically blocks only the duplex pathway. Disable automatic duplex printing in your print settings on Windows 11 or macOS and select single-sided only, which bypasses the duplex unit entirely. However, you should still address the underlying jam to avoid potential damage to other printer components over time.
What causes paper to jam in the duplex unit in the first place?
Duplex jams usually happen when paper is too thin, too thick, or has rough or torn edges that catch on the guide rails. Low-quality paper, paper that has been left in humid conditions, or using the wrong paper size for duplex printing can all contribute. Using the correct paper weight (typically twenty pounds) and keeping paper in a dry storage area significantly reduces duplex jams.
Is the duplex unit something I need to replace, or can it always be repaired by clearing jams?
Most duplex jams can be resolved by removing paper debris without replacing any parts, but repeated jams or mechanical damage to the flapper arm or drive shaft means the assembly needs replacement. Duplex unit replacements typically cost between seventy-five and one hundred fifty dollars depending on your Brother model, plus labor if you use a service center rather than ordering the part yourself.
Why does my Brother printer keep saying Print Unable 57 even after I cleaned it out?
Persistent errors after cleaning usually indicate a faulty duplex sensor, a stuck flapper arm, or a failed stepper motor controlling the duplex mechanism. These components cannot be cleared of debris—they require professional service or replacement of the entire duplex unit assembly. If you are handy with electronics, Brother sells replacement duplex units that you can install yourself by following your model's service manual, though technician installation is safer.
