How to Clean and Troubleshoot an HP OfficeJet Pro 8620 Printer with BCH Cleaning Kits

Question:

I'm trying to restore my HP OfficeJet Pro 8620 to good working condition without dismantling it. I plan to use BCH cleaning solutions and a proper cleaning kit. Which BCH cleaning kit should I get for this model? Also, what's the best way to safely dispose of the old ink I flush out during the process?

Answer:

1. Which BCH Cleaning Kit Is Correct for My HP OfficeJet Pro 8620?

The HP OfficeJet Pro 8620 uses pigment-based inks—HP 950 (black) and HP 951 (color)—so you’ll need tools and solutions specifically suited for cleaning pigment ink.

We recommend the following combination for a complete clean and flush:

Green Cleaning Solution

This triple-action formula is designed for pigment, dye, and sublimation inks. It's stronger than our clear solution and safer than the red one for general home or office users. It will effectively loosen clogs, especially if the printer has been idle.

BCH Printhead Cleaning Kit

For the OfficeJet Pro 8620, we recommend using a syringe-and-tubing cleaning kit compatible with HP printheads. Ensure it has adapters or tubing fine enough to fit the ink ports without forcing.

You can find our compatible kits by visiting our HP printer cleaning kits collection [https://bchtechnologies.com/collections/hp-printhead-cleaning-kits].

Red Cleaning Solution

Since you've mentioned possibly using the red solution, please note that it is the strongest we offer and is meant for professional-level, severe clog cases. Returning it unused is a wise call if you choose not to use it. Do not leave it inside the printer for longer than 24 hours if used.

2. How to Properly Dispose of Flushed-Out Ink

Disposing of flushed ink must be done carefully to avoid environmental harm. Here's a responsible approach:

Safe Disposal Steps:

1. Contact Your Local Waste Management Service:
   Ask if they accept household hazardous waste, especially “printer ink and toner.” Many municipalities have designated drop-off locations or collection events for printer fluid, chemicals, and paint.

2. Obtain an MSDS Document from HP:
   HP provides Material Safety Data Sheets (MSDS) for its inks. Present this document to your waste disposal facility for safer processing. You can download MSDS sheets from HP’s official website by searching for “HP 950 MSDS” or “HP 951 MSDS.”

3. Do NOT Pour Ink Down the Drain or Toilet:
   Ink is a chemical pollutant and can contaminate waterways or septic systems. Always collect waste ink in a sealed container and hand it to a certified facility.

4. Use a Leak-Proof Container:
   When flushing ink into a bowl or catch tray, use something with a secure lid so you can later transport it safely to the disposal site.

A Note on Repair Limitations

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility [https://bchtechnologies.com/printer-repair-service]. Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks to get your printer to drop it off. Our services are structured to repair either the whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage [https://youtube.com/@bchtechnologies]. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thanks again for reaching out. We value your engagement and wish you the best in restoring your HP 8620. If you need more clarification, don’t hesitate to follow up!
