A customer states that when she removes the printed pages from her laser printer output tray, the black ink smears all over her fingers. Which of the following is the most likely problem? Group of answer choices a. Inked ribbon b. Fuser unit c. Primary corona d. Cleaning blade e. Erasure lamps

Answer: b) Fuser unit

Explanation:

Fuser unit is the device in the form of rollers that blends the toner onto the paper on which printing is done. Laser printer has two units of these rollers in heated form for working.

According to the question, fuser can be the part responsible for smudging of ink on fingers of customer because he/she tries to remove printed page from output tray as powered toner gets changed into liquid toner ink of black color. Other options are incorrect because cleaning blade, erasure lamps, inked ribbon and primary corona are not the devices that can fuse toner on the printing paper with ink. Thus, the correct option is option (b).
