10
HP Printer
Severity: ModerateWhat Does This Error Mean?
The error 10 means your HP printer cannot read the memory chip on a toner or ink supply. Each cartridge has a small electronic chip that stores information about ink level and type. When the printer cannot communicate with this chip, it shows error 10.
Affected Models
- HP LaserJet Pro M400 Series
- HP Color LaserJet Pro M200 Series
- HP LaserJet Enterprise M600 Series
- HP LaserJet Pro MFP M428
- HP LaserJet Pro M100 Series
Common Causes
- The toner cartridge is not fully seated in its slot and the chip contacts are not aligned
- The electronic contacts on the cartridge chip are dirty or smudged with toner dust
- The cartridge's memory chip is defective or damaged from handling
- A third-party or refilled cartridge has an incompatible chip that the printer cannot read
- The supply contacts inside the printer are dirty or have toner buildup on them
How to Fix It
-
Turn off the printer and open the cartridge access door. Remove the cartridge that is causing the error.
On some HP LaserJets, the display will indicate which cartridge slot has the problem.
-
Locate the small electronic chip on the cartridge — it is usually a small gold or green circuit on one end. Gently wipe it with a dry lint-free cloth.
Do not use water or cleaning solutions on the chip. A dry wipe is sufficient to remove toner dust.
-
Also clean the matching contacts inside the printer where the cartridge chip connects. Use a dry lint-free cloth to wipe away any toner dust.
These contacts are small metal pins or pads inside the cartridge slot. Be gentle to avoid bending them.
-
Reinstall the cartridge firmly until it clicks or locks into place. Close the access door and turn the printer back on.
If the error clears, the contacts were simply dirty. Print a test page to confirm everything is working.
-
If the error persists, try a different cartridge. If a new genuine HP cartridge works, the original cartridge has a defective chip.
If every cartridge triggers the error, the printer's internal contacts need professional attention.
When to Call a Professional
The error 10 is usually fixable at home by cleaning contacts or replacing the cartridge. If genuine HP cartridges still trigger the error after cleaning, the supply contact assembly inside the printer may be damaged. A technician can clean or replace the internal contacts for $40 to $80. For LaserJet printers still under warranty, contact HP Support at 1-800-474-6836.
Frequently Asked Questions
What information is stored on the cartridge chip?
The chip stores the cartridge type, ink or toner level, manufacturing date, and region code. The printer reads this information to track usage and ensure compatibility. If the chip cannot be read, the printer cannot verify the cartridge is correct.
Will using third-party cartridges cause error 10?
Sometimes. Third-party cartridges use aftermarket chips that may not be fully compatible. Some work perfectly, while others are not recognized by certain HP printer models. If a third-party cartridge causes error 10, try a genuine HP cartridge to confirm.
Can I override the error and keep printing?
On some HP LaserJet models, you can press OK or Continue to dismiss the error temporarily. However, the printer may not track ink levels correctly with an unreadable chip. It is best to fix the underlying contact issue or replace the cartridge.
