Page 24
(3) Cutter lock error Explanation: Cutter operation is disabled. Abnormality occurred. PE LED: ERROR LED: ERROR LED repeats blinking 2 times fast and blinking 1 time slow. Restore Condition: Remove the fault and restore by pressing the FEED switch (with MSW3-1 set to OFF) or by DLE EMQ 1 or 2 command (with MSW3-1 set to ON).
Page 25
(2) Low voltage error Explanation: Occurs when the Vp voltage supplied to the printer is lowered. If occurred, immediately turn the power OFF. PE LED: ERROR LED: ERROR LED repeats blinking 3 times fast and blinking 1 time slow. Restore Condition: Irreparable However, it can be restored by turning the power OFF and then raising the Vp voltage to the range of DC 16.9 to 27.8 V.

4 ) Others (1) Paper near-end Explanation of status: When the diameter of the roll paper deceases to a certain degree (* differs with the status of using Near-End sensor), the Paper Near-End sensor responds and allows PE LED to light to indicate roll paper is low.
Page 27
(3) Head Up (when LT2220/2310 is used) Explanation: When Head Up is set, ERROR LED lights. PE LED: ERROR LED: ON Restore Condition: Set Head Down. PE LED ERROR LED (3) Platen Open (when LT2221/2321 is used) Explanation: When Platen is opened, ERROR LED lights. PE LED: ERROR LED: ON Restore Condition: Close Platen.
Feed Switch Function • When pressed once, paper feed of one line occurs based on the amount of line feed set by ESC 2 and ESC 3. However, paper feed is not available in the following cases. (1) When the FEED switch is set to disable by ESC c 5 (2) When paper-end detector detected no paper (3) With Head Up.
5.3.1 Self-printing 1) Function Function to enable the printer setting status to be verified by printing 2) Start of self-printing When the power is turned on with the FEED switch pressed and held in print ready state, printer status is printed on the roll paper. Explanation of printed item is as shown below.
5.3.2 Hexadecimal Dump Printing 1) Function Prints the data sent from the host in hexadecimal code and the corresponding characters. 2) Starting hexadecimal dump With paper set and Head Up (or Platen Open), turn the power on while pressing and holding the FEED switch.
5.3.3 Memory Switch Setting Mode 1) Settable memory switch MSW1、MSW2、MSW3 2) Starting memory switch setting mode With paper set and Head Up (or Platen Open), turn the power on while pressing and holding the FEED switch and then press the FEED switch twice, set Head Down (or Platen Close) to start the setting mode.
