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. Non-printable
codes, such as control codes, are shown as dots.
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.
