Samsung Multifunction Printer Error Code U2-1113

The U2-1113 error means the LSU (Laser Scanning Unit) motor is not operating normally. The LSU motor drives the polygon mirror that steers the laser beam during printing, and the printer's control board has detected that the motor is not functioning within expected parameters. The printer will halt operation until the fault is resolved.

A simple power reset is unlikely to permanently clear the U2-1113 error because it is triggered by an active hardware fault, not a software glitch. The error will typically return as soon as the printer attempts to initialize the LSU motor. The underlying cause must be identified and corrected before the printer will resume normal operation.

Repair costs depend on the specific failed component. If only the wiring harness needs reseating, the cost may be limited to a service call fee, typically in the range of $50 to $100. If the LSU assembly requires replacement, parts and labor combined can range from $150 to $400 or more depending on the printer model and service provider. In some cases, the repair cost may approach the value of an older printer, making replacement worth considering.

Basic checks like reseating the LSU wiring harness are within reach for a technically confident user. However, the primary diagnostic step requires accessing EDC mode and running a specific motor test, which is typically reserved for trained technicians. If the LSU motor or assembly itself has failed, replacing the LSU unit is the most reliable fix and involves disassembling internal printer components.

The printer will generally stop functioning when this error is active, so continued use is not possible without repair. There is no significant safety risk to the user from this particular error, as the printer halts operation automatically. Attempting to force the printer to bypass the error is not recommended, as it could lead to further internal component damage.
