Checking for Nozzle Clogging If printing is faint or affected by banding in different colors, make sure the print head nozzles are clear by printing a test pattern to check the nozzles. Important • When using cut sheets, do not move the release lever until instructions (guidance) for removing the paper are displayed. Moving the release lever during printing or maintenance operations will cause the printer to stop. Note • By default, nozzles are checked at fixed intervals.
