How to Fix HP 8025 Printing Blank Pages: Printhead Cleaning and Troubleshooting

Question:
I reassembled my HP ProMax 2025 after successfully installing your PFG. While the ink carriage moves as expected, the pages are not printing.
I removed the ink cartridges to facilitate disassembly and left them out for about two weeks. Now, I'm still getting blank pages even after replacing the black cartridge with a new one and setting the printer to print in black only.
Could this be related to the ribbon cable I had to reconnect during reassembly, or perhaps the ink dried out from sitting idle? What steps should I take next?

Regarding your HP 8025 printing blank pages, The issue may stem from a clogged printhead, especially considering the cartridges were left out for an extended period. The HP 8025, like many printers, has an independent printhead that can dry out, leading to clogging. Here are several steps you can follow to troubleshoot and potentially resolve this issue:
  1. Run the Printer's Built-In Cleaning Cycle
Your HP 8025 has an internal cleaning function designed to address minor clogs:
  • On the printer's touch screen, navigate to Settings > Printer Maintenance > Clean Printhead.
  • Follow the on-screen instructions.
  • After the cleaning cycle, print a test page to check for improvements.
This step often helps with minor blockages, but if you still see no results, proceed with the manual cleaning process.
 
2. Manual Cleaning with Water or Isopropyl Alcohol
If the built-in cleaning fails, a more hands-on approach is needed. Here to manually clean the printhead:
  • Turn off the printer and unplug it.
  • Remove the ink cartridges and set them aside.
  • Locate the printhead (the component where the cartridges sit).
  • Dampen a lint-free cloth with warm distilled water or 70% or higher isopropyl alcohol.
  • Gently wipe the printhead's electrical contacts and nozzles to remove ink clogs. Take care not to damage any delicate parts.
  • Let the printhead dry entirely before reassembling and turning the printer back on.
 
3. Soaking the Printhead
For more stubborn clogs, soaking the printhead can help loosen dried ink:
  • If your printer allows it, carefully remove the printhead.
  • Place it in a shallow dish filled with warm distilled water or isopropyl alcohol.
  • Allow the printhead to soak for 10-15 minutes.
  • After soaking, blot the nozzles gently with a paper towel to remove any loosened debris.
  • Let the printhead dry thoroughly before reinstalling it.
 
4. Check the Ribbon Cables
Since you mentioned reconnecting a ribbon cable during reassembly, it's worth double-checking the connection. Loose or improperly connected cables can disrupt communication between the printer and its components. Ensure the 7-pin cable you reconnected is securely in place, as it could influence printer operations.
 
5. Replace the Printhead
If none of the above methods work, the printhead might be too clogged or damaged to be replaced. For more details, you can refer to our video on HP 8025 printhead cleaning (https://youtu.be/WHGPnfujj9M) and our step-by-step guide on maintaining your 8025e printer, including printhead cleaning and cartridge lifespan, on the BCH Technologies blog (https://bchtechnologies.com/blogs/blog/maintaining-your-8025e-printer-printhead-cleaning-and-cartridge-chip-lifespan?srsltid=AfmBOoqzVfxnk9t_NFjK5MI_kBIVr7avWnC00HUKzxf6Zj_1VTslfsps).
