3.2 Keypad Operation

EJECT: ejects an inserted document if the print buffer is empty.

A: moves a document up 1/60" with each depression. If held depressed, the

document will slowly move into the printer. Also initiates document

insertion if the printer is configured for key rather than automatic

insertion. (See 3.5.1)

B: moves a document down 1/60" with each depression. If held depressed,

the document will slowly move out of the printer.

FUNCT: enters previously keyed digits as a function code. All function codes

beginning with 9 are reserved for internal printer operations. All other

function codes are transmitted to the host system and their usage is host

defined. If no digits have been entered, FUNCT will override automatic

alignment for one document.

CLEAR: erases any previously keyed digits before they are transmitted to the host

by the FUNCT or ENTER keys.

ENTER: transmits previously keyed digits to the host system. All responses are

host defined. This key also initiates document printing if the printer is

configured to delay printing until the ENTER key is pressed (See 3.5.1).

0 to 9: enter digits to be transmitted to the host by the FUNCT or ENTER keys.

Key depressions appear on the lower display line.

3.3 Display Operation

The display has 2 lines of 16 characters each and is used to display messages

both from the printer and the host system. There is a contrast knob to the left of

the ribbon instruction/configuration label that should be adjusted for maximum

legibility depending on the display viewing angle. When the printer is turned on,

"READY" will be displayed.

DP9 printers have lamps to identify dual port activity when DUAL PORT is set to Y

(see 3.5.2). The lamp labeled “A” indicates the port closest to the printer’s left side

is active and the lamp labeled “B” indicates the port closest to the printer’s right

side is active.

KEYPAD & DISPLAY PANEL

If one of the green lights is on and there is no paper in the printer, there is more

print pending. Insert paper and the printer will finish printing.
