Self Test Printing

If the ON-LINE switch is pressed at power-on and held until the initialization operation ends, a given pattern is printed repeatedly. During printing, the printer is in the OFF-LINE state. To terminate printing, press the ON-LINE switch until the printing stops. When the switch is released, the printer performs the initialization operation, enters the ON-LINE state, and the ON-LINE lamp goes on.

If paper-empty or cover-open is detected, printing is terminated while the printer is still in the OFF-LINE state. When printing is terminated due to a paper-empty condi- tion, the P.EMP lamp is lit, the buzzer sounds for 3 seconds, and the P.EMP signal is output. This state can be reset by loading paper and pressing the RESET or ONLINE switch once. The printer then starts the initialization operation and enters the ON-LINE state. If the RESET or ON-LINE switch is pushed though no paper has been inserted, the printer enters the OFF-LINE state, the P.EMP lamp lights, and the buzzer rings for 3 seconds after executing the initialization operation.

When printing is halted because of a cover-open condition, the printer performs initialization and enters the ON-LINE state only after the printer cover is closed and the RESET or ON-LINE switch is pressed.

The self test print examples in the two modes (Epson Printer and IBM Graphics Printer) are shown on pages 15 and 16.

Automatic Printing

When data input exceeds one line of data, printing is automatically carried out without a print command unless the data are graphics data; there is no automatic print signal with graphics data. After automatic printing, the printer is in the same condition as

it was prior to printing except when the function is cleared.

Bold Printing

In order to create bold print, a 1/120 inch dot is printed to the right of the initial dot.
