When your printer is malfunctioning, you may encounter different types of lines, including:

• Vertical lines: These lines often appear when there are issues with the printer’s rollers or the ink/toner cartridge.
• Horizontal lines: These are typically caused by clogged print heads or low ink levels.
• Streaks or smudges: Irregular marks on the page may result from dirty printer heads or poor-quality paper.

Identifying the type of line can help you pinpoint the cause and choose the appropriate fix.
