Understanding the status LED

The color of the LED indicates the machine's current status.


	Some LEDs may not be available depending on model or country. To resolve the error, look at the error message and its instructions from the troubleshooting part. You also can resolve the error with the guideline from the computer’s Printing Status or Smart Panel program window. If the problem persists, call a service representative.

^[a]Estimated cartridge life means the expected or estimated toner cartridge life, which indicates the average capacity of print-outs and is designed pursuant to ISO/IEC 19752. The number of pages may be affected by operating environment, percentage of image area, printing interval, graphics, media and media size. Some amount of toner may remain in the cartridge even when red LED is on and the printer stops printing. ^[b]When the imaging unit has reached its end of life, the machine will stop printing. In this case, you can choose to stop or continue printing from the SyncThru™Web Service ( Settings > Machine Settings > System > Setup > Supplies Manangement) or Samsung Easy Printer Manager (Device Settings > System > Supplies Management). Turning off this option and continuing to print may damage the device’s system.
