Question
When a page that was printed on a laser printer is touched, the image on the paper smears. Which of the following is MOST likely the cause of this issue?
A. Duplexing assembly
B. Fuser
C. Toner
D. Transfer belt
Answer
C. Toner
Explanation
When a printed image from a laser printer smears upon touch, the most likely cause is improper toner fusing (Option C). Laser printers use toner, a fine powder, to create images on paper. The fusing process melts and bonds the toner to the paper surface using heat and pressure rollers (fuser assembly). If the fusing is inadequate, the toner remains loosely attached and easily smears when touched.
Common reasons for improper toner fusing include:
- Faulty fuser assembly: The fuser assembly may be worn out, damaged, or operating at incorrect temperatures.
- Low-quality or incompatible toner: Using substandard or incompatible toner can affect fusing and adherence.
- Environmental factors: Extreme temperatures or humidity levels can interfere with the fusing process.
- Paper type: Using unsuitable paper types or finishes can prevent proper toner bonding.
To resolve the issue, try replacing the toner cartridge with a high-quality, compatible one. If the problem persists, the fuser assembly may need to be replaced or serviced. Adjusting environmental conditions or using recommended paper types may also help.
