(2) Operation of the printer mechanisms (motor, cartridge ribbon mechanism, belt, etc. ) The self-test function is pre-programmed and can be performed by turning the POWER switch on while depressing the LF switch. All characters provided by the internal software are printed out on the paper by this operation.

The self-test function cannot be performed when the printer is out of paper. To check all interface logic including the interface connector, proceed as follows: a) Connect ACKNLG signal pin No. 1 with a lead wire. b) Turn the DIP switch 2-3 (on the control circuit board) ON to effect auto-line feed. c) Set the adequate ASCII code data to be printed. To obtain low logic level signals, connect the data transfer line required for printing (pin Nos. 33, etc. ) * Example of printing "Z" "Z"-[5, A]H-(0101 1010) In this case, connect pin Nos. Setting of DIP Switches In order to suit the user's specific requirements, desired control modes are selectable by the two built-ion DIP switches. The DIP switches (SW1 and SW2) located on the control circuit board of the Printer are as shown in Fig. To gain access to the DIP switches, the upper case of the Printer must be removed. NOTE: Turn the power off whenever you attempt to open up the printer case. Adequately discharge static electricity which might be charged in your body, or it may cause damages to internal electronic parts such as LSl's, IC's, etc. Remove the manual paper feed knob (black knob on the right side) by pulling it straight out, with firm but steady force. [. . . ] Namely, the level of SLCT IN at the pin No. 36 of the interface connector is "HIGH". With SLCT IN at "LOW level, the Printer is always placed in the Selected state, and the DC 1/DC 3 code is not valid. When power is applied, if SLCT IN is at "LOW' level or the DIP switch pin l-8 is OFF, the Printer is regarded as in the Deselected state. -90- I Hex. [. . . ]
