SOLVING PROBLEMS
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 computer and the printer. Data dump mode provides an exact printout of the codes reaching the printer. To start data dump mode, do the following.
1.Make sure that the printer is loaded with paper.
2.Hold down the 
button until you see "INITIALIZE" on the printer’s display
3.Hold down the 
button until you see "READY P:DUMP" on the printer’s display.
4.Print something from the computer, or run a program that causes the printer to print something (such as a word processing package). Your printer prints out all the codes sent to it in hexadecimal (base 16) format as shown in the following sample.
5.To turn off the data dump mode and stop printing, press 
to switch the printer off line. When the printer goes off line, either switch off the printer or hold down
the 
button until INITIALIZE appears on the display.
Look at the sample printout. It shows which codes are being sent to the printer. In the text field, printable characters are shown as their true ASCII characters.
For example, on the fifth line, the first two codes are 73 and 20. Code 73 represents the letter s, and code 20 represents a space. Look at the fifth line of the text field; you will see an s followed by a space.
53
