# Why are there streaks, lines or the wrong colors on my print-outs?

If your print-outs are streaky, faded, have lines on them that shouldn't be there, or are otherwise poor in quality, this may be due to a problem with the printer or a low ink/toner supply.

- Fading text or images

  You may be running out of ink or toner. Check your ink/toner supply and buy a new cartridge if necessary.

- Streaks and lines

  If you have an inkjet printer, the print head may be dirty or partially blocked. Try cleaning the print head (see the printer's manual for instructions).

- Wrong colors

  The printer may have run out of one color of ink or toner. Check your ink/toner supply and buy a new cartridge if necessary.

- Jagged lines, or lines aren't straight

  If lines on your print-out that should be straight turn out jagged, you may need to align the print head. See the printer's instruction manual for details on how to do this.
