Streaks or lines on inkjet prints are usually caused by one of three issues.

Print head alignment
If the print heads are misaligned, streaking can occur. Use the alignment tool in your printer’s control panel or software to correct this.

Dirty internal parts
Streaks along the edges of the page often mean ink has built up on rollers or internal components. Cleaning the printer, following the instructions in the manual, should resolve the issue.

Print head wear
Inkjet printers have a limited lifespan. With regular or heavy use, print heads can wear out, leading to ongoing streaking that may not be fixable.
