Samsung Multifunction Printer Error Code U3-3114

U3-3114 is a document jam error specific to the ADF or DADF unit on Samsung multifunction printers. It means the printer's sensors have detected that a sheet fed through the automatic document feeder has stopped moving or become obstructed in the paper path. The printer halts all ADF-based operations until the jam is cleared and the error is resolved.

A power cycle (turning the printer fully off and back on) can clear the U3-3114 error after the jammed document has been physically removed. However, if the underlying cause is a worn pick-up roller, debris in the paper path, or a faulty sensor, the error will return with the next ADF job. The reset alone is not a fix if the root cause has not been addressed.

If the fix is simply removing a jammed document and cleaning the rollers, there is no parts cost involved. If the pick-up roller is worn and needs replacement, roller kits for Samsung ADF units typically range from around $15 to $50 depending on the specific model. If a sensor or internal ADF component requires replacement and professional service is needed, labor and parts combined can range from $75 to $200 or more depending on the service provider and printer model.

Start by opening the ADF cover and gently removing any jammed pages, pulling in the direction of paper travel to avoid tearing. Check the entire feed path including the input tray, internal rollers, and output area for torn fragments. After clearing all paper, power the printer off completely, wait about 30 seconds, and power it back on. If the error returns on subsequent jobs, inspect the pick-up roller for wear and clean all ADF rollers with a lint-free cloth.

ADF-based scanning and copying functions will be unavailable while this error is active, but flatbed scanning directly on the glass is generally unaffected. It is safe to use the printer in that limited capacity. Attempting to force documents through a jammed feeder can cause torn paper fragments to become lodged deeper in the mechanism, so avoid pulling documents against the direction of travel.
