QuestionQ12

Hardware and Network Troubleshooting

When a user scans a page using a printer, a line consistently appears on the printout. However, the line is absent when the user prints directly from the printer.

Which of the following maintenance actions should a technician take to resolve the problem?

Explanation

A line that appears only in scanned or copied output indicates contamination on the scanner glass rather than a printing-path fault. Dust, smudges, or debris on the flatbed glass can distort the scanned image and create lines, while direct printing remains unaffected. Cleaning the flatbed glass removes that source of the defect.
