I Have Problems With The Print Quality On My Mfc9420cn. I Have Changed The Opc B
It shows vertical and horizontal lines/ streaks. Have cleaned it inside, replaced the OPC belt and all the toners, which improved the quality to some extent but still some white lines/ streaks (Note fuser unit is fine).
Any suggestions?
