Hi, I’ll be glad to help with the printer issue.
You can reset the drum counter after replacement.
Follow these steps:
1.Remove the drum unit and toner cartridge. Wait 1 minute.2.Replace the drum unit and toner cartridge into printer.3.The Drum LED continues to blink if the drum counter was not reset when you replaced the drum. We need to reset this now!4.Open the front cover of the printer5.Press and hold down Go button for about 4 seconds until all the LEDs light up.6.Once all 4 LEDs are lit, release the Go button7.Close the front cover.8.Your drum is now reset.
