3.1.2The Buttons
This section explains the various meaning and uses of the buttons, including
their light indicators, when applicable. Keep in mind that the buttons’ functions depend on the mode the printer is in: the Normal Mode and Program Mode.
ON LINE
Pressing this button switches the printer from off-line to on-line or vice versa. When the printer is on-line (ON LINE LED is lit), the printer is able to receive information from the computer and print it. All other buttons (except ( ‘ZR,==) button under certain conditions) are inactive when the printer is on-line.
When the printer is off-line, the printer is unable to receive information and print, but the other buttons can be used. If the printer is in the Program Mode, pressing this button will exit the printer from the Program Mode, and enter it into the Normal Mode.
PRINT
This button is active only when the printer is off-line. Pressing the button will print and eject any page of data. If there is no data in the printer, the depression of the button will be ignored. When printing is in operation, the LED is lit.
ERROR SKZP/<
This button is active only when the printer is off-line. In the Normal Mode, pressing this button has no effect if no alarm condition exists. However, if an alarm or warning condition exists, pressing this button causes the printer to return to the previous state after corrective action has been taken.
When the printer is off-line and in the Program Mode, this button is called NEXT(<). During programming, pressing this button displays the various items under a category for the operator to select next in the sequence.
