Symptoms
- Multiple lights blinking in a specific pattern
- Display shows a numeric or alphanumeric error code
- Printer refuses to print until the error is cleared
- Same error keeps returning after a restart
Likely causes
- CommonPaper jam not fully clearedEven a small missed paper scrap can trigger a persistent jam error.
- CommonCartridge issue (empty, not seated, not recognized)Many blink patterns specifically indicate a cartridge-related problem.
- CommonCover or door not fully closedAn open sensor triggers specific error codes on many models.
- PossibleInternal component fault (fuser, motor, sensor)More serious codes point to a specific internal part needing service.
What to do
- Note down the exact blink pattern (which lights, how many blinks, any colors) or the exact error code shown on the display.
- Search the printer manufacturer's support site for that specific model and error code or blink pattern, since these are usually documented precisely.
- Check for and clear any paper jam, even in less obvious spots like the duplex unit or output tray.
- Confirm all cartridges are seated properly and all covers/doors are fully closed.
- Power cycle the printer by unplugging it for a full minute before plugging it back in.
- If the manual lists the code as requiring service or points to a specific worn part (like a fuser or maintenance box), follow that specific guidance rather than generic troubleshooting.

When to call a pro
