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:

Illumination and meaning
To  b e  a b l e  t o  i n di c a te  a  la r g e  n u m b e r  o f  s t a t u s  s i tu a ti o n s bo th  
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 61 for more information.

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 20~ 24 
lb. (75~90 g/m²) paper designed for use in copiers and laser printers. 
Suitable types are:
•Hammermill® Laser Printer Radiant White, 24 lb. US 
Bond (90 g/m²)
•Xerox
® 4024, 20 lb. US Bond (75 g/m²)
•Oki
® 52206101 Bright White Proofing Paper, 32 lb. US 
Bond (120 g/m
2)
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 should be free from twist, curl or other 
deformations. 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 5161 White Laser Label (Letter size)
• Avery 7162, 7664, 7666 White Laser Labels (size A4).

Multi Purpose Tray
The Multi Purpose Tray can handle the same sizes as the 
Cassette Tray but in weights up to 54 lb. (203 g/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 3.94 
in (100 mm) and lengths up to 47.24 (1200mm) [banner 
printing]. 
For paper lengths exceeding Legal 14in. (356mm) use paper 
stock between 24 and 34 lb. (90 g/m² and 128 g/m²) and the 
face up (rear) paper stacker.
When using the Multi Purpose Tray, each sheet of paper can 
only be fed one at a time.
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 20 lb. (80g/m²) standard paper, and can 
handle paper stocks up to 32 lb (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 20 lb. (80 g/
m²) standard paper and can handle stocks up to 54 lb (203 g/
m²).
Always use the Face Up Stacker and the Multi Purpose Tray for 
paper stocks heavier than 47 lb. (176g/m²).
