  12. 12. PREVENTIVE MAINTENANCE Print Head MaintenanceMaintaining a barcode printer, cleaning it regularly and replacing parts aswhen required is necessary to ensure high print quality and consistent printperformance. The print head is the most critical component of a barcodeprinter and without proper cleaning and maintenance, it will produce lessthan desirable print quality that can cause operational down time andwastages as well. 90% of print quality problems result directly from improperuse or care of the print head.Clean your print headsCleaning print heads at regular intervals can extend their life considerably. Asa general rule, print heads should be cleaned every time the ribbon isreplaced. Cleaning is fairly quick and easy with cleaning pens, swabs or cardsand is very inexpensive compared to constantly replacing print heads.
