APPENDIX (M-T51/T51A PRINTER SPECIFICATIONS)7.1 Care and Handling of the Printer7.1.1 Precautions1) The printer adopts a line thermal head. Avoid using the printer where dust and dirt particles exist,which will shorten the thermal head life.2) Use only recommended paper to ensure print quality and thermal head life. Failure to do this maycause a trouble with the printer.3) Store the paper roll in a cool and dry place. Avoid areas where it would be exposed to directsunlight, high temperature, and solvent. Failure to do this may cause the paper roll to be colored ordiscolored.7.1.2 Caution for handling1) Do not touch the thermal head by hand, a screwdriver, and tweezers, etc.2) To prevent static electricity from discharging through the thermal head, perform a countermeasureby using the following instruments. Failure to do this may cause the thermal head to be damaged.• Personal grounding• Antistatic floor mat• Static eliminator• Static protective package during transportation7.1.3 Prohibited actions1) NEVER touch the thermal head, the portion near the thermal head, and the motor surface being hotduring printing and just after printing.2) None of foreign object is attached to the paper and the platen.3) NEVER pull out the paper forward and backward while the thermal head is down.4) NEVER touch the blade portion of the auto cutter.7- 1

7. APPENDIX (M-T51/T51A PRINTER SPECIFICATIONS) EO18-11004A7.3 Paper Specifications7.3 Paper SpecificationsCAUTION!Use only paper which meets specified requirements. Use of non-specified paper may shorten thehead life of the printer, result in problems with print quality, or cause a paper feed failure. All papershould be handled with care to avoid any damage to the paper. Read the following guidelinecarefully.• Do not store the paper for longer than the manufacture’s recommended shelf life.• Store the paper in a cool, dry place. Avoid areas where they would be exposed to direct sunlight,high temperature, high humidity, dust or gas.• A contact of chemical or oil may discolor or erase the printed record.• Rubbing the paper hard with nail or hard object may discolor the paper.• The paper end should not be pasted to the core.1) Paper width 57.5±0.5mm2) Outer roll diameter Up to ∅80mm3) Paper type Only paper rolled onto a core is acceptable, however, the paper endshould not be pasted to the core.Thermal paper rolled with the print side facing outside.Recommended paper type: KF50 (KANZAN)TF50KS-E2C (Nippon Paper Industries)P-350 (KSP)7.4 General MaintenanceCAUTION!NEVER touch the thermal head, the portion near the thermal head, and the motor surface being hotduring printing and just after printing. Do not touch the thermal head by hand, a screwdriver, andtweezers, etc.1) Cleaning the thermal head and the platenIn case paper particles and dust are attached to the element of thermal head, clean the thermalhead and the platen in the following procedure. Failure to do this may lower the print quality.(1) Raise the Paper Free Lever to separate the thermal head from the platen.(2) Carefully clean the element of thermal head with a cotton swab slightly moistened with alcoholssolvent such as ethanol, methanol, and IPA. (Use of chemicals excepting alcohols solvent maydamage the thermal head.)(3) Make sure that alcohols solvent fully evaporated, and then return the Paper Free Lever to returnthe thermal head in the original position.2) Removing jammed paper(1) Cut the paper at the paper inlet.(2) Raise the Paper Free Lever to seprate the print head from the platen.(3) Carefully pull out the remian of paper straight from the paper outlet.7- 3
