220-1101 Question #794: Real Exam Question with Answer & Explanation

Question

A user is experiencing an issue with a network printer. The technician tests the printer and notices shadows on some of the attempted test prints, with others having a line down the page and faded text. Which of the following should the technician replace to resolve the printer issue?

Options

• APrinthead
• BFuser assembly
• CPickup rollers
• DCarriage belt

Explanation

The symptoms of shadows, lines, and faded text on printouts are indicative of a problem with the printer's fuser assembly. This component is responsible for bonding toner to the paper, and its malfunction results in improper toner adhesion and print quality issues.

Common mistakes.

• A. A printhead is a component found in inkjet printers and is responsible for ejecting ink; laser printers, which are commonly network printers, do not have printheads.
• C. Pickup rollers are responsible for feeding paper into the printer; issues with pickup rollers typically cause paper jams or misfeeds, not print quality defects like shadows or faded text.
• D. A carriage belt is found in inkjet printers and moves the printhead across the page; it is not present in laser printers and its failure would typically cause movement errors or grinding noises, not print quality issues like faded text or shadows.
