4.5 Hexadecimal Dump Printing
This function is to print all received data in hexadecimal numbers. If problems such as missing data, data duplication, etc. should occur, this function allows checking whether or not the printer is receiving data correctly.
Load the paper into the printer and keep the printer cover open. With the FEED button pressed and held, turn the printer power on and then close the printer cover. The printer prints “HEX dump print mode” followed by the received data printed in hexadecimal numbers and some characters.
CAUTION!
■The printer prints “.” if there is no characters corresponding to data.
■During hexadecimal dump, functions except some command will be disabled.
■If print data DOES NOT cover a line, press the FEED button to print the line.
When you press the FEED button three times consecutively, or you turn the printer power off, or the printer receives a reset signal from the interface, the hexadecimal dump printing is terminated.

4.6Error Indication
●Paper end
Paper out is detected in two steps: paper
●Printer cover open
During printing, do not open the printer cover. If you open the printer cover accidentally, the ERROR LED blinks. Check the paper, pull the paper straightforward several cm (or inches) out of the printer, and then close the printer cover. Printing resumes automatically. Sending a command to resume printing may be required depending on the memory switch setting.
●Thermal head overheat
When you print dense characters or dark image, the head temperature rises. If the head temperature exceeds a specified level, the printer stops printing operation and waits till the head temperature is lowered. During waiting, the ERROR LED blinks. When the head temperature is lowered, printing resumes automatically.
●Cutter lock
If the cutter blade stops operating due to paper jam or the like, the ERROR LED blinks. Remove the cause of the trouble and press the FEED button. If the blade still does not move and the printer cover cannot be opened, refer to the section
