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. In data dump mode, the printer

produces as exact printout of the codes it receives.

Make sure that paper is loaded and the printer is off.

Hold down the SelecType button while you turn on the

printer. Make sure you hold the button down until you see

message HEX DUMP on the display.

Next, run any program that causes the printer to print (either

an apphcation program or a program written in any

programming language). Your printer prints out all the codes it

receives in hexadecimal format, as
