Data Dump Mode Data dump mode is a special feature that allows experienced users to find the cause of communication problems between the printer and computer. In data dump mode, the printer produces an exact printout of the codes it receives. To use data dump mode, follow these steps: 1. Make sure paper is loaded and the printer is off. 2. Hold down both the LF/FF and LOAD/EJECT buttons while you turn on the printer. 3. Next, run either an application program or a program you have written in any programming language. Your printer prints all the codes it receives, as shown below. 4. To turn off data dump mode, press the PAUSE button to stop printing and then turn the printer off. Look at the data dump shown in step 3. On the left side of the printout, all the codes are printed in hexadecimal format. On the right side of the printout, the same codes appear as printable characters or, if they are nonprintable codes-such as control codes-they appear as dots. By looking at either the characters printed in the text field or the hex codes, you can see exactly what codes are being sent to the printer. 3-24 Using the Printer
