Does the Spongeless Conversion Cover Fit HP 67XXL Black and Color Cartridges?

Question

I emailed previously but did not receive a response. Will your spongeless conversion kit fit the double-extra-large HP 67XXL black and color cartridges? Please advise.

Answer

Yes, this is the correct spongeless conversion cover for both the HP 67XXL black cartridge and the HP 67XXL tri-color cartridge. The cover is designed around the physical cartridge shell, so it can be used with the regular HP 67, HP 67XL, and HP 67XXL versions when the cartridge body has the same compatible shape.

The primary difference among the standard, XL, and XXL versions is their original ink capacity and internal reservoir arrangement. The XL and XXL cartridges generally use the same basic cartridge platform but are supplied with a greater usable ink capacity. Because the conversion cover replaces the original top section and allows the cartridge to function as a refillable spongeless reservoir, the original capacity designation does not normally affect how the cover attaches.

For a regular HP 67 cartridge, additional preparation may be required because the internal reservoir can contain plastic dividers or partitions. These dividers restrict the available reservoir space and may interfere with a proper spongeless conversion. They must be carefully removed before installing the conversion cover. Once the internal dividers have been removed and the reservoir has been cleaned and prepared correctly, the standard HP 67 cartridge can be converted in essentially the same manner as the XL or XXL version.

The XL and XXL cartridge bodies may require less internal modification, but the cartridge should still be inspected before installation. Manufacturing differences, regional cartridge variations, or previously remanufactured cartridge shells can occasionally affect the internal structure. Confirm that the cartridge shell matches the one shown in the product photographs and installation video before permanently attaching the cover.

Please also keep in mind that this product is the conversion cover rather than a complete replacement cartridge. The original cartridge's printhead, electrical contacts, and recognition circuitry remain in use. The conversion cover changes the ink-storage system, but it does not repair a damaged printhead, restore burned nozzles, reset an incompatible cartridge, or correct an electronic recognition problem.

During the conversion, avoid touching the copper electrical contacts or the nozzle plate. The cover must be installed with an airtight and ink-resistant seal. An incomplete seal can allow air into the reservoir, while excessive internal pressure or overfilling can cause ink to leak through the printhead. After filling the converted cartridge, allow the ink system to stabilize and check for leaks before installing it in the printer.

The complete preparation and installation procedure is demonstrated in the video provided on the product page. Following that video is important, especially when converting a regular HP 67 cartridge that still has its original internal dividers. Therefore, whether your cartridge is labeled HP 67, HP 67XL, or HP 67XXL, the conversion cover can be used as long as the cartridge has the compatible HP 67-series shell and is prepared according to the instructions.

Printer and cartridge problems can be difficult to diagnose because many repairs require direct inspection and hands-on testing. For that reason, we are unable to provide individualized remote troubleshooting, repair instructions, or technical support for printer repairs. We do offer in-person evaluation and repair through our local printer diagnostic and repair facility [https://bchtechnologies.com/printer-repair-service]. Due to high demand, service is handled on a first-come, first-served basis, and it may take several weeks before an appointment or printer drop-off becomes available. Our service options cover either complete printers or selected printer components, with instructions explaining how to proceed. We also recognize that professional repair may not be the most economical choice in every situation, so we strongly encourage customers to begin with independent online research. You can search YouTube or visit the homepage of our BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies]. To locate a particular topic, use the search icon near the "About" section on the channel's menu bar. We receive dozens of questions each day asking whether we have videos on specific subjects. Since we have produced repair videos for more than nine years, it is difficult to remember every video individually. Using YouTube's channel-search feature is usually the fastest approach, and YouTube may also recommend helpful videos from other experienced creators.

Thank you again for contacting BCH Technologies and for your patience while waiting for our response. We truly appreciate your interest in our products and your support of our technical content.
