FAQs

These cartridges don’t come with a chip, so you’ll need to reuse the chip from your original HP 923 cartridge. Simply remove the chip from your old cartridge (gently, using a small tool) and attach it to the new one.

First, check if the chip is securely attached (it should click into place). If that doesn’t work, clean the chip’s metal contacts with a dry cloth—dust can block recognition. If issues persist, contact our support team with your printer model and update version.

We don’t sell standalone chips. If the chip break happened during your first use, contact us—we may offer a partial refund to help offset the cost of a new original cartridge for the chip.

Our cartridges are sealed to prevent leaks, but improper chip installation can cause issues. If you notice leaks, remove the cartridge, check the seal, and reattach the chip more carefully. If leaking continues, contact support with photos—we’ll replace the set if needed.

Go to your printer’s settings menu > select “HP+ Services” or “Subscription Settings.” If you see options like “HP+ Status: Active,” then it’s enabled. For unactivated printers, this section will prompt you to set it up.

Only if the “e” model has never had HP+ activated and HP+ is permanently disabled. However, most “e” models come with HP+ pre-installed as a default, so compatibility is rare. We recommend confirming your printer’s HP+ status first.

A firmware update could make your printer suddenly reject the cartridges, showing errors like “Invalid Cartridge”. If this happens, contact us—we can help troubleshoot or send updated cartridges if available.

Yes, that’s common with compatible cartridges. The warning is triggered by the chip’s estimate, not actual ink levels. You can keep printing until quality fades—just don’t harm your printer.

In most Canon printers, color cartridges are used for occasional calibration, but minimal ink is consumed. If you set your printer to “Black Only” mode, color usage drops significantly—you’ll get the full life from your color cartridges.

This is normal! Our compatible LC3033 cartridges don’t display ink levels on the printer’s screen—the “????” indicator is expected and won’t affect printing. To check real-time ink levels, use Brother’s printer status software on your computer.

For Windows: Open “Devices and Printers” > Right-click your Brother printer > Select “Printer Properties” > Go to the “Maintenance” tab > Click “View Ink Levels”. For Mac: Open “System Preferences” > “Printers & Scanners” > Select printer > “Options & Supplies” > “Utility.”

No, your printer will keep printing until the ink runs out. The question marks are just the printer’s way of saying it can’t read the cartridge’s ink data, but functionality remains normal.
