@JoshMFlorez, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding black streaks on the paper! 

We're thrilled to have the opportunity to assist you and provide a solution.  

The streaks in your printed document could be caused by several issues related to the printer's ink or toner system. Here are the most common solutions based on the type of HP printer you are using:

1. Clean the Printhead (Inkjet Printers)

If you are using an inkjet printer, the printhead might be clogged. Follow these steps:

Use the printer’s built-in cleaning function:

1. Open the HP Printer software on your computer.
2. Navigate to the "Printer Maintenance" or "Tools" section.
3. Select "Clean Printhead" and follow the on-screen instructions.
4. Run the cleaning process multiple times if necessary.

Manual Cleaning:

1. Remove the ink cartridges.
2. Use a lint-free cloth slightly dampened with distilled water to wipe the printhead.
3. Let it dry completely before reinserting the cartridges.

2. Check and Replace Ink or Toner (Inkjet/Laser Printers)

• If the ink or toner is low or expired, it may cause streaks.
• Replace the affected cartridge if the problem persists.

3. Clean the Rollers

• Dirty rollers can cause streaking or misalignment.
• Open the printer, locate the rollers, and clean them using a damp, lint-free cloth.

4. Check for Software or Driver Issues

• Update your printer drivers from the HP official website.
• Run the HP Print and Scan Doctor tool to diagnose and fix issues.

5. If You Are Using a Laser Printer

• The streaks could be due to a dirty or damaged drum unit.
• Open the printer and check if the drum or toner cartridge has excess toner residue.
• If the drum is scratched or worn out, it may need to be replaced.

Next Steps

1. Try the printhead cleaning function first.
2. Check for low ink or toner levels and replace if needed.
3. Clean the rollers and printhead manually if the issue continues.
4. If the issue persists, let me know the printer model, and I can give more specific instructions.  

Take care, and have an amazing day!
