After changing a toner cartridge and drum, a user’s printer would no longer print, and the Toner light was staying on. The following procedure fixed it.
- Turn the unit off.
- Open the front cover.
- Hold the Go button while turning the unit back on.
- When all the LEDs come on, release Go, then press Go twice.
- When all the LEDs come on a 2nd time, press Go 5 times.
- Once the Ready light comes on, close the front cover.
