Encountering the “Non-HP chip detected” error on your HP Color LaserJet Pro MFP M479fnw or Fdw can disrupt your workflow, especially when you’re using third-party toner cartridges. This error often appears after a firmware update and prevents the printer from recognizing compatible non-HP toner chips. In this guide, we’ll walk you through practical steps to fix this issue and restore your printer’s performance.
🔍 What Causes the “Non-HP Chip Detected” Error?
HP regularly pushes firmware updates to enhance printer security and functionality. However, these updates are also designed to block unauthorized or third-party toner chips. As a result, when your printer detects a non-HP chip, it disables the cartridge and displays the error.
This built-in protection can be frustrating for users who choose affordable, compatible toner cartridges from trusted non-HP brands.
⚠️ What Happens When the Error Appears?
Once the “Non-HP chip detected” message is displayed:
The printer may stop printing entirely.
Toner status could show as empty or low, even if the cartridge is full.
You may be forced to purchase expensive original HP toner.
Leaving this issue unresolved can lead to unnecessary expenses and downtime.

Before applying any fixes, identify the root cause:
Check Firmware History: If your printer updated recently, this could be the trigger.
Inspect the Toner Chip: Non-HP chips may look different or include extra circuitry.
Error Display: The printer shows “Non-HP chip detected” when attempting to print.
