Samsung Multifunction Printer Error Code S4-2112

S4-2112 is a warning that the fax memory on your Samsung multifunction printer is almost full. The printer reserves a dedicated memory buffer for storing fax data, and this code appears when that buffer is nearly exhausted. The most likely cause is faxes being held in the Secure Receive queue that have not yet been printed or deleted. Printing or removing those held fax jobs will clear the condition.

A simple power cycle reset will not clear S4-2112 because the fax data stored in memory persists through restarts. The error will return as long as the memory buffer remains near capacity. You need to actively print or delete the stored fax jobs through the control panel to free memory and resolve the error. A factory reset would clear stored faxes, but this would result in permanent data loss of all held fax documents.

In most cases, S4-2112 requires no parts or paid repair at all, since it is resolved by printing or deleting faxes from the Secure Receive queue at no cost. If the error persists after clearing the queue and a firmware fault or memory hardware issue is suspected, a professional diagnostic visit could range from $50 to $150 depending on the service provider. Replacement memory components, if ever required, would add additional parts cost, but hardware failure is a rare cause of this specific code.

Access the Secure Receive job list through the printer's control panel menu and print or delete the fax jobs stored there. This releases the memory they are occupying and should resolve the S4-2112 warning. Also check for any pending outgoing fax jobs that may be queued and consuming additional memory. Once the memory level drops below the threshold, the error should clear automatically.

Basic printing, copying, and scanning functions are not affected by S4-2112, so those operations can continue safely. However, the fax function is at risk: if the memory fills completely before you clear the queue, the printer will be unable to receive new incoming faxes and those transmissions will be lost. Addressing the error promptly is important if you rely on the fax feature.
