Be careful not to turn the power off or let the printer be reset via an interface while this command is being executed.
Confidential APPENDIX A: MISCELLANEOUS NOTES A.1 Notes on Printing and Paper Feeding 1) Because the TM-T81 printer is a line printer, it automatically feeds paper after printing the data. Therefore, when the line spacing for one line is set to a smaller value than the print data, paper may be fed more than the set amount just to print the data.
Confidential A.2 Notes on Supplying the Power to the Printer • Connect the external power supply to the power supply connector of the printer. Then plug in the external power supply and turn it on if necessary. Be sure not to connect the external power supply with the wrong polarity. If it is connected incorrectly, the internal circuit fuse of the printer may be blown or the external power supply may be damaged. • The power supply voltage is within the range of 24 V ± 7%.
Confidential A.4 Other Notes 1) Printer mechanism handling • Do not pull the paper out when the cover is closed. • Because the thermal elements of the print head and driver IC are easy to break, do not touch them with any metal objects. • Since the areas around the print head become very hot during and just after printing, do not touch them. • Do not use the cover open button except when necessary.
Confidential APPENDIX B: PAPER ROLL SETUP B.1 Replacing the Paper Roll 1) Open the printer cover. (Put your fingers in the dints indicated by A and lift the cover.) 2) Install a paper roll and pull out paper a little. 3) Close the printer cover.

Confidential APPENDIX C: RECOVERY FROM THE AUTO CUTTER ERROR • If a foreign object such as a push pin or paper clip drops in the auto cutter and causes the auto cutter to lock up, the printer enters an error state and begins the recovery operation automatically. (The error LED flashes continuously, but it is possible for the error to be corrected automatically.) If the problem is not serious, the auto cutter returns to its normal position without any intervention by the user.
Confidential APPENDIX D: ADJUSTING THE PAPER ROLL NEAR-END SENSOR LOCATION The remaining detectable amount of paper on the roll paper varies with the inside and outside diameters of the paper core. The minimum detectable amount of paper on the roll paper can be set using the following method: 1) The inside diameter of the paper spool should be 12mm {0.47"} and the outside diameter of the paper spool should be 18mm {0.71"}. Specified thermal paper should be used.
Confidential APPENDIX E: PRINT HEAD CLEANING Paper dust on the heating elements may lower the print quality. follows: 1) Open the printer cover. In this case, clean the print head as 2) Clean the thermal elements of the print head using a cotton swab moistened with alcohol solvent (ethanol, methanol, IPA). NOTES: 1. 2. Do not touch the print head thermal elements. Do not scratch the print head. 3) Insert a roll paper and close the print head.
Confidential APPENDIX F: NOTES ON USING THE DRAWER KICK-OUT CONNECTOR 1) Drawer specifications (see Section 2.2.3, Drawer kick-out connector) Drawer specifications differ significantly depending on manufacturer and model number. Make sure that the specifications of the drawer used meet the following conditions when connected to the drawer kick-out connector. These conditions also apply to any equipment (other than a drawer) that is connected to the drawer kick-out connector.
Confidential The drive signal waveform generated when the drawer is driven according to the above conditions is shown in Figure F-1. ON OFF t1 × 2ms t2 ≥ (t1 × 4) × 2 ms Figure F-1 Drawer Drive Signal Waveform (Formulas F-1 and F-2) The ON time depends on the specifications of the drawer used. Be sure to check the drawer specifications and set a suitable time. To use a drawer that does not meet the conditions of Formulas F-1 and F-2, see the following section.
Confidential An example program in which the drawer connected to drive signal 1 is driven with an ON time of 200 ms is shown below.
