\nInconsistent toner quality or the presence of impurities mixed into the toner can lead to the appearance of black spots or smudges during printing.<\/p>\n
\nA worn cleaning blade or an uneven magnetic roller surface can cause uneven toner distribution, resulting in streaks or background graying on the printout.<\/p>\n
\nIf the toner cartridge has poor sealing or an excessive buildup of internal toner residue, it can easily contaminate the printed pages during the printing process.<\/p>\n
\nAccumulated dust inside the printer or a dirty fuser assembly can also leave black lines or spots on the paper.<\/p>\n
\nACO compatible toner cartridges undergo rigorous quality control and component screening processes to effectively minimize such printing issues, ensuring clean and crisp output.
