How to Fix Print Quality Streaking on HP Printers

Streaks and bands almost always trace back to the print head, not the printer's electronics — and HP's built-in cleaning tools solve most cases without a service visit.

Symptoms to look for

• Horizontal white lines running through printed pages
• One color consistently missing or faded
• Text appears smudged or uneven in darkness

What causes it

Dried ink in the print head nozzles from infrequent use is the leading cause, followed by low ink levels and, less often, a misaligned print head after a cartridge change.

How to fix it

1. Open HP Smart or the printer's control panel and run 'Clean Printheads'.
2. Print a nozzle check pattern to confirm which colors are affected.
3. Run the cleaning cycle up to 2–3 times if streaking persists, waiting between cycles.
4. Run 'Align Printer' after cleaning to correct positioning.
5. If streaking remains after 3 cleaning cycles, the cartridge itself may need replacing.
