3.2 Keypad Operation
EJECT: ejects an inserted document if the print buffer is empty. Should a document remain
partially in the printer, press eject again to fully eject paper. If ‘CLEAR EJECT
JAM” is displayed, press the CLEAR key and EJECT again.
↑
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. See the printer diagram on page 43. When the printer is turned on,
"READY" will be displayed.
DP9 printers have green lamps to identify which port is active 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.
