| Home > Problem Solver # Printing Hex Dump If you are an experienced user or a programmer, print a hexadecimal dump to isolate communication problems between the printer and your software program. In hex dump mode, the printer prints all data it receives from the computer as hexadecimal values. Follow these steps to print a hex dump: Note:
The hex dump feature is designed for a connection with DOS-based PC.
| When using continuous paper, make sure that the paper is loaded and the printer is turned off.
| To enter hex dump mode, turn on the printer while holding down both the LF/FF and Load/Eject buttons.
| When using A4 (210 × 297 mm, 8.3 × 11.7 inches) or wider (such as letter size paper) single-sheet paper, load paper in the printer.
| Open a software program and send a print job to the printer. Your printer prints all the codes it receives in hexadecimal format.
By comparing the characters printed in the right column with the printout of the hexadecimal codes, you can check the codes being received by the printer. If characters are printable, they appear in the right column as ASCII characters. Nonprintable codes, such as control codes, are represented by dots.
| To exit the hex dump mode, press the Pause button and eject the printed page(s), and turn off the printer.
