What are the common causes of Error 5100 appearing on a Canon G1010 printer?

The most common causes for Error 5100 on a Canon G1010 include obstructions in the print head's path (e.g., small pieces of paper, dust, or foreign objects), a dirty or damaged encoder strip which tells the print head its position, a print head that is improperly seated or defective, or a problem with the print head's motor or the main logic board that controls its movement. Sometimes, issues with the ink absorption pad or waste ink system can also trigger this error.
