Hi
Did you change the Toner Cartridge?
If you have and it still happens check the fuser if it looks dirty or built up toner it could be going soon.
Other than that I would need more info

the toner cartridge was replaced. the problem only occurs on 1 to 2 sheets per 50 sheets on average.

Check the transfer roller for wear
