Transferring New HP Cartridge Chips

Today, we will show you how to transfer the chips from newer HP cartridge models. Specifically, we’ll look at the HP 564, 920, 902, 934, and 935 OEM cartridge models.

If you have one of these cartridge models and have refilled it before, you may be aware that when you reinsert the cartridge into the printer, it still says that there are low ink levels, despite being freshly refilled.

You could keep printing after it says it’s low and wait for the printer to stop keeping track of the ink levels. This allows you to print forever without getting that message again, but it won’t be able to tell you when you’re running low on ink.

One way I see people try to remedy this is by replacing the standard cartridge with a see-through third-party cartridge. These see-through cartridges, just like the standard ones, have an ink reading chip that will show that it’s full at first and eventually stop tracking the ink levels.

Therefore, the chips in these see-through third-party cartridges are no better for reading refilled ink levels than those on standard cartridges. Still, the blank cartridges are only a fraction of the cost of a standard ink cartridge, so you could just harvest the chips and order a see-through third-party ink cartridge.

HP Changed Designs

HP used to make cartridges with chips that were exposed, and anyone could easily remove them. Still, after enough people started doing it, they started making the chips embedded into the cartridges so that that was no longer possible.

Despite that, this tutorial shows you how to harvest the embedded chips off these new HP ink cartridges. If you look at the bottom of the cartridge, you should be able to see a small box. This box corresponds to a hole in the printhead assembly. It is there to help the chip line up with the printer’s contact pin.

There is also a ridge on the printhead assembly. We’ll need to cut a small piece from the edge of the cartridge, a little further than the hole but not far enough to hit the ridge. To do this, I used a rotary tool with variable speed. We want to keep the speed as low as possible while remaining effective so that the tool doesn’t melt the plastic.

Next, we’ll polish that piece and make it a bit thinner. To ensure we cut and filed it down to the right size, we placed the piece into the printhead assembly and attempted to fit the new cartridge on top of it. It should be able to fit just fine, but there will be a bit of extra height. This shouldn’t be a problem, but you’ll need to push on the little tab to get it to fit in.

Since the chip we used is from a genuine OEM cartridge, it allows us to use a non-standard cartridge without dealing with the pesky “non-genuine cartridge” related error messages. You should now be able to use this new cartridge as much as possible without the printer giving you any trouble.
