A blockage would mean no magenta. A constant magenta line means that cartridge is (for some reason) output magenta constantly. Unfortunately no printer manufacturer will provide information on the circuit between that printer and electronics inside the cartridge. Meaning most printer end up canned.
Once upon a time, you could order a new electronics board from the printer manufacturer. Sometimes one is available. Often at a price about one half the cost of a new printer.
Bruce's solution once worked on every printer. Many now will not even operate in B&W if it discovers a problem with its color cartridge. That was a new surprise.
Light usage would never be destructive. The most likely reason for all such failures is a manufacturing defect.
