Chapter 5 The Self Test

■The purpose of the self test

The self test checks whether the printer has any problems. If the printer does not function properly, contact your dealer. The self test checks the following:

•Control circuit functions

•Printer mechanism

•Print quality

•Control ROM version

•DIP switch settings

•Presence or absence of a validation detector

nRunning the self test

➀Make sure the ribbon cassette and paper roll have been installed properly. Make sure the printer cover and the take-up device cover or the roll paper cover are closed properly.

➁Turn on the power while holding down the FEED button. The self test begins.

➂First the self test prints the current printer status, which provides the following information:

• Control ROM version • DIP switch settings

➃After printing the current printer status, it prints “Self-test printing. Please press FEED switch”. The PAPER LED blinks and the printer enters the test printing standby state. Press the FEED button to restart test printing.

➄After the printer com- pletes a certain number of lines, it prints “* * *

completed * * * ”, and stops printing automati- cally.

*The printer goes off-line during and after self-test printing. Turn the power off and on again to put the printer on-line before transmitting data from

the host computer. TM-U300C/U300D TM-U300PC/U300PD
