How can I prevent the Canon G1010 error 5B00 from occurring frequently?

Preventing the error entirely is difficult as it's a wear-and-tear component. However, you can extend the life of the waste ink pads by minimizing unnecessary print head cleaning cycles. Only perform cleaning when print quality issues are evident. Ensure you're using genuine Canon inks to avoid clogs that might require more frequent cleaning. Regular, consistent printing (rather than long periods of inactivity followed by heavy use) can also help.
