IPF 650. If idle for even a week, it starts the print head cleaning before a job. After cycling through all of that it then stops, gives a "Hardware Error 03800500-2F43", advises turning off the printer and re-starting. When I do that it prints fine. That is until another job a week later.
I recently replaced the print head with a genuine Canon. However, it has done the same routine long before the new print head.
