Self Test - Citizen CT-S651 Type II Mode D'emploi

4.4 Self test

While paper is loaded, press and hold the FEED button while turning the power
on. Hold the FEED button down for about one second and then release it to start
self test. The printer prints its model name, version, DIP switch settings,
memory switch settings, and a list of built-in fonts.
Note:
*: Printers with a USB interface do not have DIP switches, so the DIP switches all appear off on the
self test printout.
