Do you offer a kit to refill cartridges for the HP Envy 4520?

Answer

Thank you for contacting us. We at BCH Technologies are grateful for your engagement and support, particularly with regard to our YouTube channel, BCH Technologies on YouTube. Your feedback plays a crucial role in further developing our technical expertise.

Yes, we do offer kits to refill cartridges for the HP Envy 4520. The cartridges for this printer are integrated, meaning the printhead is built into the cartridge itself. This design choice by the manufacturer allows for easy replacement of the printhead with each new cartridge, but it also means that the printhead lacks advanced anti-clogging mechanisms found in permanent printheads.

For refilling these cartridges, we recommend using dye ink for two main reasons: it clogs less and is easier to unclog compared to other types of ink.

If this is your first time refilling, we suggest starting with our First-Timer Ink Refill Kit (EZ30T) (https://bchtechnologies.com/first-timer-ink-refill-kit-for-hp-inkjet-printer-cartridges-60-61-62-63-64-65-ez30-t). This kit includes everything you need for 5-10 refills and comes with a set of priming tools. Save these tools, as you will only need to purchase ink for future refills. You can watch a step-by-step guide on how to use the kit on our YouTube channel (https://youtu.be/s19ypQ0r2Dk).

For ongoing refills, we recommend using our standard dye ink (https://www.bchtechnologies.com/refill-ink/refill-ink-for-hp/standard-600-ml-4-color-refill-ink-for-hp-kd600x-ch.html), which is the best option for these cartridges.

If you don't have a priming clip, you can retrofit a household vacuum to achieve the same priming effect. Detailed instructions for this method are available on our blog (https://www.bchtechnologies.com/blog/solved-black-and-color-print-head-clogged-not-printing-part-i-integrated-printhead). For a text version of the instructions, please visit our support page (https://support.bchtechnologies.com/hc/en-us/articles/200545279-How-to-refill-HP-60-61-62-63-64-65-66-67-74-75-901-OEM-Cartridges).

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For instance, resolving a simple clog might involve advice on unclogging procedures. However, if the printer remained inactive during downtime, a comprehensive service for the ink system could be necessary. Situations like a "paper jam" can arise from hundreds of potential causes, and solving such an issue has become something of an in-office jest. So, we're not able to 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 before we can get your printer to drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly 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.

Thank you again for reaching out to us. We hope this information helps you successfully refill your HP Envy 4520 cartridges. If you have any further questions, please don't hesitate to contact us.
