1 S4M Cleaning Exterior The exterior surfaces of the printer may be cleaned with a lint-free cloth. Do not use harsh or abrasive cleaning agents or solvents. If necessary, a mild detergent or desktop cleaner may be used sparingly. Interior Remove any accumulated dirt and lint from the interior of the printer using a soft bristle brush and/or vacuum cleaner. Refer to Table 1 for the correct interval for cleaning the printhead and platen roller. Poor print quality as represented by uneven print darkness, blank areas in bar codes or graphics, or illegible numbers and letters, may indicate a dirty printhead and/or platen roller. Recommended Preventive Maintenance Schedule AREA METHOD INTERVAL Printhead Platen Roller After every roll of media (or 500 feet of fanfold media) when printing in direct thermal mode. Media Sensor Air blow After every roll of ribbon when printing in thermal transfer mode. Ribbon Sensor Media Path (Dancer Assembly) Air blow + cloth These intervals are intended as guidelines only. You may have to clean more often, depending upon your application and media. Ribbon Path Page 1
