A field technician responds to a support ticket regarding a departmental laser printer. Users report that printed text and images appear sharp and complete, but the toner easily smudges or wipes off the page when touched. Which of the following components is most likely failing and requires replacement?
- Fuser assemblyCevap
- BTransfer roller
- CPrimary charge roller
- DDeveloping roller
Cevap
Fuser assembly
The fuser assembly uses heat and pressure to melt toner into the fibers of the paper during the final stage of electrophotographic printing. If the heating element or pressure rollers inside the fuser malfunction, toner is deposited onto the page correctly during transfer but fails to adhere, resulting in text that smudges or rubs off effortlessly.
