Data Dump Mode
Data dump mode is a special feature that makes it easy for
experienced users to identify the cause of communications problems
between the printer and the application programs. The data dump
mode produces a printout of the codes reaching the printer.
Follow these steps to use the data dump mode:
1.
Make sure that the printer is loaded with either single-sheet. or
continuous paper.
2.
If the printer is on, switch it off. Then hold down both ON LINE
and FORM FEED at the same time you turn on the printer.
The display reads Hd and the printer waits for data. If you are
using continuous paper, the printer feeds the paper
automatically, then waits for data.
