Samsung Multifunction Printer Error Code C1-1120

The C1-1120 code means the toner cartridge has reached the end of its rated service life. The printer's monitoring system tracks toner usage through the cartridge chip and triggers this alert when the cartridge is depleted. This is a consumable replacement notification, not a hardware fault. Printing the supply information report will confirm the cartridge status.

Continuing to print after the C1-1120 alert appears can result in visibly degraded output, including faded text, streaking, or incomplete coverage across the page. While the printer itself is not at risk of damage from a depleted cartridge, print quality will suffer. It is best to replace the cartridge promptly to maintain acceptable output.

A basic power cycle or soft reset will not permanently clear the C1-1120 error if the cartridge chip continues to report end-of-life status. The error is tied to the data stored on the cartridge chip, so the only reliable resolution is replacing the depleted cartridge with a new one. Some third-party refilled cartridges include a reset chip, but compatibility and reliability can vary by cartridge supplier.

Start by printing the supply information report to confirm the toner cartridge life is at end-of-life. Once confirmed, replace the toner cartridge with a new compatible unit for your specific Samsung model. After installing the new cartridge, the printer should recognize it and clear the C1-1120 error automatically.

Since this error is caused by a depleted toner cartridge, the fix involves purchasing a replacement cartridge. Depending on the Samsung printer model and whether you choose an original or compatible third-party cartridge, costs typically range from around 20 to 120 dollars. No service labor should be required for a standard cartridge swap.
