If toner is not fusing properly, what should you verify first?

When toner is not fusing properly onto the paper, the first step is to verify the voltage and heat output of the fuser. The fuser assembly is responsible for melting the toner and binding it to the paper. If the fuser is not reaching the appropriate temperature or if there is an issue with its electrical components, the toner will not adhere properly, resulting in smudges or toner that does not stick.

Ensuring that the fuser is functioning correctly is vital because no matter the quality of the toner cartridge, the condition of the drum, or the type of paper being used, if the fuser is inadequate, the results will be compromised. Addressing issues with the fuser should be the priority, as it directly affects the fusion process essential for print quality.
