Printer Shows Unknown Error or Cryptic Error Codes
Getting a vague 'Unknown Error' or confusing error code on your printer? Here's how to decode common printer errors for HP, Canon, Epson, and Brother.
What's Happening
Your printer shows an error, but instead of telling you something useful like "out of paper," it displays "Unknown Error" or a cryptic code like "E5", "B200", or "0x00000709". These error messages are frustrating because they don't tell you what's actually wrong. Let's decode the most common ones and fix them.
Quick Checks (Do These First)
- Write down the exact error code or message. You'll need it for troubleshooting.
- Turn the printer off and on. Many errors clear with a simple restart.
- Check for obvious issues: paper jams, open doors, empty trays, low ink.
- Unplug the printer for 60 seconds. This does a deeper reset than just powering off.
Step-by-Step Fixes
For HP Printers
Common HP error codes:
- 59.F0 Error: Fuser problem - turn off, wait 30 minutes, restart
- 0x6... errors: Usually carriage jams - open and check for stuck paper or debris
- Supply Problem: Remove and reseat ink cartridges
- For any HP error, try the HP Print and Scan Doctor tool (free download from HP)
- It automatically diagnoses and fixes most common issues
For Canon Printers
Common Canon error codes:
- B200: Printhead problem - clean the printhead or it may need replacement
- E05: Ink cartridge not recognized - remove, clean contacts, reinstall
- 1403: Printhead temperature error - turn off, wait 15 minutes
- For most Canon errors, hold the power button for 5 seconds while the printer is on
- This forces a reset that clears many temporary errors
For Epson Printers
Common Epson error codes:
- E-01: Paper jam - check all paper paths
- W-12: Ink cartridge problem - remove and reinstall cartridges
- Flashing lights: Count the flashes - check Epson's support site for your model
- Epson has a Maintenance Tool built into the printer driver
- Access it from Control Panel > Devices and Printers > right-click printer > Printing Preferences
For Brother Printers
Common Brother error codes:
- Paper Jam: Even after clearing, you may need to open and close all doors
- Drum Error: The drum unit may need cleaning or replacement
- Init Unable: Hardware initialization failed - full power reset required
- Brother printers often need you to press a specific button sequence to clear errors
- Check the display for prompts or consult the manual
If Nothing Worked
Search for your specific error code plus your printer model on the manufacturer's website or forums. Some errors indicate hardware failures that can't be fixed with software resets.
When to Call a Pro
If the same error keeps returning, or if you've tried the manufacturer's recommended fixes without success, the printer may have a hardware problem. Error codes starting with certain prefixes (like B200 on Canon) often indicate parts that need professional replacement.
