Dell Error 093-919 — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
The Dell error 093-919 is a toner cartridge recognition error that stops your printer from functioning until resolved. This error appears on your printer display or in the print queue on your Windows 11 or macOS computer, and it's frustrating because your printer won't print anything until you fix it.
The good news is that this error has a straightforward cause in most cases: the cartridge isn't making electrical contact with the printer, the cartridge sensor is blocked, or you're using an unsupported cartridge. We'll walk you through the exact steps a technician would take to resolve this, starting with the easiest fixes and moving to more involved troubleshooting.
How to fix it — step by step
- Power cycle your Dell printer completely. Turn off your printer using the power button and unplug it from the wall outlet. Wait for at least 30 seconds while the printer is completely unpowered, as this clears the printer's memory and resets the error state. Plug the printer back in and power it on, then check if the error has cleared.
- Remove and visually inspect the toner cartridge. Open your printer's cartridge access door and carefully remove the toner cartridge by pulling the green or colored handle toward you. Look at the cartridge for any obvious damage, leaking toner, or protective tape that may still be attached. If you see protective tape on the cartridge, peel it away completely and set the cartridge aside on a clean surface.
- Clean the gold contact points on the cartridge. Locate the small gold or copper electrical contacts on the bottom or back of the toner cartridge where it connects to the printer. Use a dry, lint-free cloth or coffee filter to gently wipe these contacts several times to remove any toner dust, paper fibers, or oxidation. Never use water, alcohol, or cleaning solutions, as these can damage the cartridge's electronics.
- Clean the cartridge sensor and contacts inside the printer. Look inside the cartridge bay where the toner cartridge sits and locate the small black or white sensor bar and the metal contact points. Use a dry, lint-free cloth to gently wipe the sensor bar and the internal contact points where the cartridge makes connection. This is often where toner dust accumulates and causes the 093-919 error.
- Reinstall the cartridge with firm, deliberate pressure. Slide the cleaned toner cartridge back into the cartridge bay, aligning it with the guides on both sides of the printer. Push the cartridge straight in with steady pressure until you hear or feel a distinct click or snap, which indicates the cartridge has seated properly and made electrical contact. Close the cartridge access door and power on the printer.
- Verify the cartridge is genuine or approved for your model. Check your cartridge box or the cartridge itself for part numbers, which should match Dell's specifications for your exact printer model. Third-party or refurbished cartridges sometimes trigger error 093-919 if they don't have proper authentication chips or if the chips are worn out. If you're using a non-Dell cartridge, try replacing it with an official Dell cartridge to see if the error clears.
- Test printing and clear the error from your computer if needed. Send a test print job from your Windows 11 or macOS computer to see if the error has resolved. If the printer prints successfully, the error is cleared. If the error still appears in your print queue or on the printer display, restart your computer to clear any cached error states in the operating system.
- Replace the toner cartridge if error persists. If you've completed all previous steps and error 093-919 still appears, the cartridge sensor inside the printer is likely failing or the cartridge itself is defective beyond cleaning. Order a replacement cartridge for your Dell printer model and install it following the same steps above. If the error continues even with a new cartridge, the printer's sensor assembly may require professional replacement.

Frequently asked questions
Will error 093-919 clear by itself or after printing more pages?
No, this error will not clear on its own and your printer will not print at all until you resolve it. The error is a safety mechanism that prevents printing because the printer cannot confirm the cartridge is authentic or installed correctly. You must complete the troubleshooting steps above before your printer will function again.
Can I use a refurbished or third-party toner cartridge to fix this error?
Refurbished and third-party cartridges sometimes trigger error 093-919 if their authentication chips are worn out or missing. Dell printers have chip readers that verify cartridge authenticity, and incompatible cartridges often fail this verification. If you're using a non-Dell cartridge, replace it with an official Dell cartridge from an authorized retailer to reliably fix this error.
What does error 093-919 mean exactly?
Error 093-919 is Dell's code for a toner cartridge recognition failure, meaning the printer cannot detect or communicate with your installed cartridge. This happens when the cartridge's electrical contacts don't touch the printer's sensors, the sensor is blocked by toner dust, or the cartridge is defective or incompatible. The error code itself tells you the issue is specifically with the cartridge, not with other printer components.
Should I contact Dell support or try these fixes myself?
These fixes are safe to perform yourself and work for the majority of users experiencing error 093-919, so start with the steps above before contacting support. If you've completed all the troubleshooting steps and the error persists, Dell support or a local technician can diagnose whether your printer's sensor assembly needs replacement. Remote technical support is also available through Dell for thirty-nine dollars if you prefer professional guidance during the troubleshooting process.
