international dialling code to tell the machine to wait for a dial 
tone. If there are frequent problems communicating with a 
particular remote machine, try programming the telephone 
number into a One-Touch key, and then change the One-Touch 
parameters for that key. Lastly, either the local or remote 
machine may require servicing. Try sending a fax to another 
location to check the local machine.
Faxing is possible but the image of the document printed 
by the remote machine is very poor :
If the faxed document has small type, complex illustrations, 
photos, or is very light or very dark, try changing the resolution. 
Copy the document on the machine to determine how it will 
transmit. The problem may be caused by telephone line 
interference. Try sending the document again later.
Unwanted reports are printed out :
Check the user function settings and turn off undesired reports.
Fax sent but received mess age was completely blank:
Make sure that the document is  loaded properly before faxing.
ADF:  face up
Glass:  face down
Image of received fax is very poor :
Contact the person sending the fax and ask them to change their 
Transmit resolution. Ask the person to make a copy of the 
document on their machine to ensu re that it is working properly. 
Then ask them to send the fax again. If there is still a problem, 
try making a copy of a document on the local machine to make 
sure it is working properly.
Dialling was tried with a Sp eed Dial number but nothing 
happened :
Make sure that the Speed Dial number being used is programmed 
correctly. When dialling a two or three digit number, be sure to 
press Speed Dial before entering the number.

Documents received ar e light or have vertical streaks on 
them, and machine is not out of toner : 
Lift the top cover and gently wipe the lens surface of the 
machines LED array. Then check to see if the toner or image 
drum need replacing (see “Replacing consumables and Spare 
Parts” on page 81).
Machine is set for delayed transmission but it did not send :
Check the display to make sure that the machine’s clock is set to 
the correct time (see Clock Adjustment).
Machine will not poll a remote machine :
Call the person at the remote ma chine and make sure that they 
have loaded documents and that  their machine is set to polling 
transmission mode.
Machine is connected to a PBX but it is not possible to dial 
out :
Be certain that the dial prefix  is entered before the telephone 
number for each number dialled or programmed into the 
machine. Additionally, the machine must be programmed for PBX 
operation before it will work with a PBX (see Connecting to a 
PBX).
Machine always answers before it’s possible to use the 
external telephone:  
If an external telephone is connected, increase the machine’s 
ring response setting.
Faxes received someti mes look distorted:
If the document received is wider or longer than the paper loaded 
in the paper tray, the machine automatically reduces the width 
or length of the document so that it will fit on the paper. This type 
of problem could also be communication related.
The display shows a invalid toner cartridge :
A toner cartridge that is not specified for use in this machine has 
been installed. Contact the nearest supplier for service.
T he display shows a invalid image drum :
An image drum that is not specified for use in this machine has 
been installed. Contact the nearest supplier for service.

INSTALLING ADDITIONAL MEMORY
This section explains how to install additional RAM memory into 
your MFP as a memory upgrade.
MEMORY UPGRADE
The basic MFP model comes equipped with 128MB of memory 
(64 Mb “on-board” and 64 Mb in the option slot). This can be 
upgraded by substituting the option memory (64Mb) with a 
memory board containing 256MB, giving a maximum total 
memory capacity of 320MB.
Installation takes a few minutes, and requires a medium size 
cross-head (Philips type) screwdriver.
1. Switch the MFP off and disconnect the AC power cable.
2. Lift the scanner.

CAUTION!
The green image drum surface at the base of each 
cartridge is very delicate  and light sensitive. Do not 
touch it and do not expose it  to normal room light for 
more than 5 minutes. If the drum unit needs to be out 
of the MFP for longer than this, please wrap the 
cartridge inside a black plastic bag to keep it away 
from light. Never expose th e drum to direct sunlight 
or very bright room lighting.

7. Carefully remove the new memory board from its 
wrapping. Try to handle the board only by its short edges, 
avoiding contact with any metal parts as far as possible. 
In particular, avoid touching the edge connector.
8. Note that the memory board has a small cutout in the 
edge connector, which is closer to one end than the other.

10. As the RAM expansion slot already contains a memory 
board (64Mb), this board will have to be removed before 
you can install the new one. To remove it proceed as 
follows:
(a) Identify the locking clips at each end of the RAM 
expansion slot.
(b) Push the clips outward and back into the printer. The 
board will pop out slightly.
(c) Grip the board firmly by its short edges and pull it 
out of the slot.
(d) Place the removed memory board in the antistatic 
bag which originally contained the new memory 
board.
11. Hold the new memory board by its short edges, so that 
the edge connector faces in towards the RAM expansion 
slot, and the small cutout is closer to the bottom of the 
printer.
12. Gently push the board into th e RAM expansion slot until it 
latches in and will not go any further.

COLOR PRINTING
The printer drivers supplied with your MFP provide several 
controls for changing the color output. For general use the 
automatic settings will suffice, providing reasonable default 
settings that will produce good results for most documents.
Many applications have their own color settings, and these may 
override the settings in the printer driver. Please refer to the 
documentation for your software application for details on how 
that particular program’s color management functions.
FACTORS THAT AFFECT THE APPEARANCE OF PRINTS
If you wish to manually adjust the color settings in your printer 
driver, please be aware that color reproduction is a complex 
topic, and there are many factors to take into consideration. 
Some of the most important factors are listed below.
Differences between the range of colors 
a monitor or printer can reproduce
> Neither a printer nor a monitor is capable of reproducing 
the full range of colors visible to the human eye. Each 
device is restricted to a certain range of colors. In addition 
to this, a printer cannot reproduce all of the colors 
displayed on a monitor, and vice versa.
> Both devices use very different technologies to represent 
color. A monitor uses Red, Green and Blue (RGB) 
phosphors (or LCDs), a printer uses Cyan, Magenta, 
Yellow and Black (CMYK) toner or ink.
> A monitor can display very vivid colors such as intense 
reds and blues and these cannot be easily produced on 
any printer using toner or ink. Similarly, there are certain 
colors, (some yellows for example), that can be printed, 
but cannot be displayed accurately on a monitor. This 
disparity between monitors and printers is often the main 
reason that printed colors do not match the colors 
displayed on screen.
Viewing conditions 
A print can look very different un der different lighting conditions. 
For example, the colors in a print may look different when viewed
