A help desk technician needs to work on a high-volume printer. Users have reported occasional paper jams and smudges appearing on printed documents. Which of the following steps should the technician do next to address these issues?
- A. Perform a full factory reset.
- B. Replace the fuser.
- C. Check and clean the rollers.
- D. Change all the ink or toner cartridges.
Answer: C
Explanation:
Paper jams and smudging in high-volume printers are often caused bydirty or worn rollers. Rollers are responsible for feeding the paper through the printer. Over time, they accumulate dust, toner residue, or wear out, resulting in misfeeds or jams. Cleaning or replacing them typically resolves this issue.
Option A (Factory reset):A full reset does not directly address mechanical issues like dirty rollers or smudging. It's a last resort and more relevant to configuration or software-related issues.
Option C (Change toner cartridges):While toner quality can affect print quality, it won't usually cause jams or widespread smudging unless the cartridge is leaking - which is less likely across multiple users.
Option D (Replace the fuser):A damaged fuser could cause smudging, but this is typically after extensive use and is not the first thing to check. Fuser issues also usually present more persistent, uniform smudges.
