| Green | Blinking | When the backlight blinks, the printer is receiving or printing data. | |
| On | The printer is on-line and can be used. | ||
| Red | Blinking | • A minor error has occurred and the printer is waiting for the error to be cleared. Check the display message. When the problem is cleared, the printer resumes. • 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. |

NOTE:
- 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.
- Some LEDs may not be available depending on model or country/region.
- When the imaging unit has reached its end of life, the printer 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 Management> Imaging unit Stop). Turning off this option and continuing to print may damage the device’s system.
