Common Black & White Printing Issues
Faded or Light Black Printing
If your black prints look gray or washed out:
- Check toner/ink levels
- Adjust print density settings
- Clean print heads (inkjet)
- Replace drum unit (laser)
Streaking or Lines
For unwanted lines or streaks:
- Run cleaning cycle
- Check for debris on drum
- Align print heads
- Replace worn components
Pro Tip:
For laser printers, if you're seeing light prints even with full toner, try removing the toner cartridge and gently shaking it side to side. This redistributes the toner and can improve print quality temporarily while you order a replacement.
