Understanding the LED
The color of the LED indicates the machine’s current status.
|Red||Blinking||A minor error has occurred and the machine is waiting for the error to be cleared. When the problem is cleared, the machine resumes.|
|On||A paper jam has occurred (see Clearing paper jams).|
[a] 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 ( > > > > ) or Samsung Easy Printer Manager ( > > ). Turning off this option and continuing to print may damage the device’s system.
Toner LED/ WPS LED/ Power LED/ Eco LED
|(Toner LED)||Orange||Blinking||Small amount of toner is left in the cartridge. The estimated cartridge life of toner is close. Prepare a new cartridge for replacement. You may temporarily increase the printing quality by redistributing the toner (see Redistributing toner).|
|On||A toner cartridge has almost reached its estimated cartridge life[a]. It is recommended to replace the toner cartridge (see Replacing the toner cartridge).|
|Off||All toner cartridges are at normal capacity.|
|(WPS LED)[b]||Blue||Blinking||The machine is connecting to a wireless network.|
|On||The machine is connected to a wireless network (see Wireless network setup).|

[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, printing interval, graphics, media type and media size. Some amount of toner may remain in the cartridge even when orange LED is on and the printer stops printing.
