Data Dump Mode

Data dump mode is a special feature that makes it easy for experienced users to find the cause of communication problems between the printer and computer. The data dump mode produces an exact printout of the codes reaching the printer.

1.Make sure that the printer is loaded with paper and turned off.

2.Hold down the SelecType button while you turn on the printer. Make sure you hold the button down until the message HEX DUMP appears on the display.

3.Run any program that causes the printer to print (either an application program or a program written in any programming language). Your printer prints out all of the codes sent to it in hexadecimal format as shown in the sample below.
