POWER-UP FUNCTIONS

In addition to their normal functions, all the control panel buttons have special functions that operate if you hold them down while switching power on.

Short test mode

If the printer is turned on while the ( ONLINE > button is pressed, the printer will enter the short self-test mode. The printer will print the version number of the printer’s ROM, followed by seven lines of the character set.

Each line will be offset by one character from the one before it. The final result will be something like Figure 2-3. (If the color ribbon is used, eachline prints in a different color.)

Figure 2-3.Short self-test

Since the self-test occupies the full width of the carriage, it is recommended that the printer is loaded with the widest paper possible to avoid damage to the print head and/or platen.
