CLEAR Switch and CHECK Indicator

If a fault condition occurs, a fault message appears on the Message Display, and the CHECK indicator flashes alternately with the ON LINE indicator. Press the CLEAR switch to indicate to the printer that a fault condition has been corrected. After pressing CLEAR, the fault status will be validated and the display updated. If all faults were corrected, the display will indicate the printer is off line.

In addition, the CLEAR switch also has the special functions noted below. Except when used to reset the printer (#1 below), the CLEAR switch operates only when the printer is off line.

1.CLEAR and RUN/STOP, pressed simultaneously, reset the printer. The printer may be reset at any time, on line, off line, or while printing. However, it is recommended that the printer be reset only when off line and no data is in the buffer, or loss of data may result.

2.CLEAR is used with the PAPER ADV switch to set top-of-form (refer to Setting Top- of-Form on page 2-9).

3.Pressing CLEAR when a configuration parameter value is displayed returns the printer to off line status. Refer to the Control Panel Configuration Diagram in the Configuration chapter.

4.Pressing CLEAR will silence the audio alarm during a fault condition.

6/8 LPI Switch

Press this switch to display the current line spacing in lines per inch (lpi). Subsequently pressing this switch steps the selection through 6, 8 and 10.3 (7/72") lpi. Use of the ENTER switch is not required to select the line spacing. The LED next to this switch lights when line spacing is other than 6 lpi. The 6/8 LPI switch functions only when the printer is off line.

NOTE: Line spacing control from the host computer will override the switch setting. Control codes from the host computer can select a line spacing other than the 6, 8, or 10.3 lpi, and that selection will be reflected on the message display.

PAPER ADV Switch

With the printer on line, momentarily press PAPER ADV to advance the paper one line; or, press and hold PAPER ADV to advance to the next top-of-form. This switch can be configF ured to advance the paper only after printing any data remaining in the buffer, or to move paF per without printing (refer to the Configuration chapter). The PAPER ADV switch is also used to set top-of-form (refer to Setting Top-of-Form on page 2-9). The PAPER ADV switch functions when the printer is on line. When the printer is on line, press the PAPER ADV switch to advance to the next top-of-form. If there is any data in the buffer, this action will not ocF cur, and the message ON LINE DATA IN BUFFER will be momentarily displayed.
