Abstract
The cleaning process best suited to the condition of an inkjet printer is selected and run, thereby removing nozzle clogging without wastefully consuming ink. The first time a cleaning switchis operated a CLcleaning process is run. If the cleaning switchis pressed a second time and the print pass count is less than e.g., 400, a CLcleaning process that uses more ink than the CLprocess is used to clean the recording head, but if the print pass count is 400 or more, the CLcleaning process is used. If the print pass count is less than 400 the third time the switch is operated, the CLcleaning process is used, but the CLcleaning process is used if the print pass count is 400 or more. If the cleaning switchis operated four or more times and the print pass count is less than 400, a YCL cleaning process that consumes substantially no ink is used to clean the recording head, but if the print pass count is 400 or more, the CLcleaning process is used.
