Can a user fix the Canon G3010 E05B error at home, or does it require professional service?

While theoretically possible for advanced users, Canon generally advises professional service for the E05B error. Replacing the ink absorber pad involves disassembling parts of the printer, which can be complex and risk damaging components or voiding the warranty if not done correctly. Furthermore, after the physical pads are replaced, a specific 'waste ink counter reset' procedure must be performed, often requiring access to service mode and specialized software not typically available to end-users. Attempting this without proper knowledge carries risks.
