Printer cartridge

[Bandaid101]

I have just replaced my toner cartridge. Previously it was a 94a cartridge and I replaced it with a 94x. The new cartridge does not lock in and creates a printer error. How do I lock the cartridge in place. I have no problem with the previous cartridge.

As for physical size and makeup, they are identical

Hi @Bandaid101,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding printer cartridge lock!  

We're thrilled to have the opportunity to assist you and provide a solution.

The HP 94A (CF294A) and HP 94X (CF294X) toner cartridges are designed for the same printer series, but the 94X is a high-yield version, meaning it has more toner inside but the same physical dimensions.

Try these steps:

Turn Off and Unplug the Printer

• Power off the printer and unplug it from the wall for safety.

Remove the Cartridge and Reinsert Properly

• Open the toner access door and remove the 94X cartridge.
• Check for any protective tape or packaging that might still be attached.
• Ensure the cartridge’s orange protective clip is completely removed.
• Slide it back in firmly until you hear a click.

Check the Cartridge Guides

• Inside the printer, locate the guide rails that hold the toner cartridge.
• Make sure they are not misaligned or blocked by any debris or old toner.

Reset the Printer’s Cartridge Recognition

• Close the toner access door and turn the printer back on.
• If the error persists, remove the cartridge, restart the printer without the toner, then turn it off again and reinstall the cartridge.

Ensure You Are Using a Genuine HP Cartridge

• If it's a third-party or remanufactured toner, some may not fit perfectly. Try using an original HP 94X cartridge.

If the cartridge still won’t lock in place, try inserting the previous 94A cartridge to check if the locking mechanism works correctly. If it does, there might be a defect in the new 94X cartridge.
