Dear friends:
Recently a custumer bought ten units of cartridge GPR40 for LBP6570, but after replacing the cartridge it starts to spill toner and prints ugly
I have tried to install three toners and all of them have the same problem.
Do u have any idea what could be the issue? Thanks.IMG_1517.JPGIMG_1518.JPGIMG_1521e.jpgIMG_1522.JPGIMG_1527.JPG
