THE OPERATION PANEL
The Operation Panel allows operator intervention and indicates 
both when the printer is operating normally and when it requires 
attention. Detailed printer status is provided by the Status 
Monitor in Windows or Printer Driver in Mac. (See “Using the 
Status Monitor” on page 67.) 
The Operation Panel incorporates 3 LEDs and 2 push-button 
switches as follows (from left to right):
>Power (Ready) LED (green)
>Paper LED (amber)
>Alarm LED (amber)
>ON LINE switch
>CANCEL switch
The switches enable printer operation while the LEDs display the 
status of the printer operation.
SWITCHES
Operation
There are two switches on the operation panel labelled ON LINE 
and CANCEL. Each has four modes of operation as follows:

LED DISPLAYS
General
Printer status (as indicated by the LEDs) can be broadly 
categorised as follows:
1.Normal status (Green): the printer is operating normally 
e.g. it is ON LINE or processing.
2.Warning status (Amber): you can continue to use the 
printer without intervention but an error may result.
3.Error status (Amber, blinking): you cannot continue to use 
the printer. Intervention is required to recover from the 
error. Fatal errors are irrecoverable and require a service 
call.
When several different status situations occur concurrently, only 
the status with the highest priority is displayed on the LEDs. 
Warning status combined with the highest-priority normal status 
is displayed on the LEDs. 
Function
A summary of the functions of each LED is given below:
LEDCOLOURFUNCTION
Power (Ready) Green (static) Indicates POWER ON, ON LINE, OFF LINE, power 
saving, data receiving, printing, job cancelling, 
warming up, density adjustment/temperature 
adjustment in progress

request
Consumable Green (static)

Illumination and meaning
To be able to indicate a large number of status situations both 
individually and in combination, the LEDs are illuminated as 
follows:
The Status Monitor in Windows provides a readable description of 
the printer status corresponding to the indications of the LEDs. In 
Mac, the printer driver provides status information once you have 
sent a document to print. In Windows, if you have the Status 
Monitor Preferences set to Pop up on alerts, this readable 
message will be presented on screen whenever an abnormal 
condition occurs. See “Using the printer software” on page 66 for 
more information.
Service call error
When a service call error occurs, all LEDs blink rapidly and 
simultaneously at 120ms intervals.

replace consumables or remove 
jammed paper, for example. The 
printer then recovers from the 
error and printing becomes 
possible again.
Blinking 3 (120mS cycle) A serious error has occurred. 
rebooting or a service call is 
required.

PAPER RECOMMENDATIONS
Your printer will handle a variety of print media, including a range 
of paper weights and sizes, including envelopes. This section 
provides general advice on choice of media, and explains how to 
use each type.
The best performance will be obtained when using standard 
75~90g/m² paper designed for use in copiers and laser printers. 
Suitable types are:
>Arjo Wiggins Conqueror Colour Solutions 90g/m²;
>Colour Copy by Neusiedler.
Use of heavily embossed or very rough textured paper is not 
recommended.
Pre-printed stationery can be used, but the ink must not offset 
when exposed to the high fuser temperatures used in the printing 
process.
Envelopes s h o u l d  b e  f r e e  f r o m  t w i s t ,  c u r l  o r  o t h e r  d e f o r m a t i o n s .  
They should also be of the rectangular flap type, with glue that 
remains intact when subjected to hot roll pressure fusing used in 
this type of printer. Window envelopes are not suitable.
Labels should also be of the type recommended for use in 
copiers and laser printers, in which the base carrier page is 
entirely covered by labels. Other types of label stock may 
damage the printer due to the labels peeling off during the 
printing process. Suitable types are:
>Avery White Laser Label types 7162, 7664, 7666 (A4), 
or 5161 (Letter);

CASSETTE TRAY
The Cassette Tray can handle paper in weights of 64g/m² to 
120g/m². The Cassette Tray is ideal for printing A4 documents of 
more than 1 page in length. 
MULTI PURPOSE TRAY
The Multi Purpose Tray can handle the same sizes as the Cassette 
Tray but in weights 75 - 203g/m². For very heavy paper stock, 
always use the face up (rear) paper stacker. This ensures that the 
paper path through the printer is almost straight.
The Multi Purpose Tray can feed paper widths as small as 100mm 
and lengths up to 1200mm (banner printing). For paper lengths 
exceeding 356mm (Legal 14in.) use paper stock between 
90g/m² and 128g/m² and the face up (rear) paper stacker.
When using the Multi Purpose Tray, feed each sheet of paper or 
envelope one-by-one, rather than stacking them. This helps to 
avoid paper jams.

Watermarked or Headed paper should be loaded print side up and 
top edge into the printer. 
FACE DOWN STACKER
The Face Down Stacker on the top of the printer can hold up to 
150 sheets of 80g/m² standard paper, and can handle paper 
stocks up to 120g/m². Pages printed in reading order (page 1 
first) will be sorted in reading order (last page on top, facing 
down).
FACE UP STACKER 
The Face Up Stacker at the rear of the printer should be opened 
and the paper support extended when required for use. In this 
condition paper will exit via this path, regardless of driver 
settings.
The Face Up Stacker can hold up to 10 sheets of 80g/m² standard 
paper and can handle stocks up to 203g/m².
Always use the Face Up Stacker and the Multi Purpose Tray for 
paper stocks heavier than 176g/m².
