This comprehensive guide will help you understand what’s causing the error and provide you with practical, step-by-step solutions to get your Canon printer working properly again.

What Is Canon Printer Error Code 5100?

The Canon printer error code 5100 is a specific fault code that indicates a mechanical obstruction or issue preventing the printer carriage from moving properly across the print path. The printer carriage is the component that holds and moves the ink cartridges back and forth during printing operations. When this movement is impeded, the printer’s internal diagnostics detect the problem and display error code 5100 as a warning mechanism.

Several factors can trigger this error code:

• Physical obstructions like paper scraps, foreign objects, or debris in the printer path
• Jammed print carriage due to mechanical issues
• Damaged or improperly installed ink cartridges
• Carriage belt problems or misalignment
• Issues with the printer’s encoder strip (the clear plastic strip that helps the printer track carriage position)
• Software or firmware conflicts affecting printer operation

This error commonly affects various Canon printer models including PIXMA series (MG5220, MG5320, MP560, MP620, MX850, etc.), but the troubleshooting methods are similar across most Canon inkjet printers. Understanding the root cause is the first step toward implementing the right solution.
