Memory boardB
This machine has 64 MB of standard memory 
and one slot for optional memory expansion. 
You can expand the memory up to 576 MB by 
installing 144 pin small outline dual in-line 
memory modules (SO-DIMMs). When you 
add the optional memory, it increases the 
performance for both copy and print 
operations.
In general, the machine uses 
industry-standard SO-DIMM with the 
following specifications:
Type: 144 pin and 64 bit output
CAS latency: 2
Clock frequency: 100 MHz or more
Capacity: 64, 128, 256 or 512 MB

TroubleshootingC
If you think there is a problem with your machine, check the chart below and follow the 
troubleshooting tips.
Most problems can be easily resolved by yourself. If you need additional help, the Brother 
Solutions Center offers the latest FAQs and troubleshooting tips. Visit us at 
http://solutions.brother.com/
.
Solutions to common problemsC
If you think there is a problem with the way your faxes look, make a copy first. If the copy looks 
good, the problem may not be your machine. Check the chart below and follow the troubleshooting 
tips.
Troubleshooting and routine 
maintenance
C
Printing or receiving faxes
DifficultiesSuggestions
„Condensed print
„Horizontal streaks
„Top and bottom sentences are 
cut off
„Missing linesUsually this is caused by a poor telephone connection. If your copy looks good, 
you probably had a bad connection, with static or interference on the telephone 
line. Ask the other party to send the fax again.
Poor print quality See Improving the print qualityon page 111.
Vertical black lines when receiving One of the corona wires for printing may be dirty. Clean the four corona wires. 
(See Cleaning the corona wireson page 146.)
The sender’s scanner may be dirty. Ask the sender to make a copy to see if the 
problem is with the sending machine. Try receiving from another fax machine. 
If the problem continues, call Brother or your dealer for service.
Received faxes appear as split or 
blank pages.If the received faxes are divided and printed on two pages or if you get an extra 
blank page, your paper size setting may not be correct for the paper you are using. 
(See Paper sizeon page 21.) 
Turn on auto reduction. (See Printing a reduced incoming faxon page 42.)
Telephone line or connections
DifficultiesSuggestions
Dialling does not work. Check for a dial tone.
Change Tone/Pulse setting. (See the Quick Setup Guide.)
Check all line cord connections.
Check that the machine is plugged in and switched on.
If an external telephone is connected to the machine, send a manual fax  by lifting 
the handset of the external telephone and dialling the number. Wait to hear fax 
receiving tones before pressing Mono Start or Colour Start.
 
						

							Troubleshooting and routine maintenance
105
C
The machine does not answer 
when called.Make sure the machine is in the correct receive mode for your setup. (See 
Receiving a faxon page 39.) Check for a dial tone. If possible, call your machine 
to hear it answer. If there is still no answer, check the telephone line cord 
connection. If you do not hear ringing when you call your machine, ask your 
telephone company to check the line.
Sending faxes
DifficultiesSuggestions
Poor sending quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your 
machine’s scanner operation. If the copy quality is not good, clean the scanner. 
(See Cleaning the scanneron page 141.)
Transmission Verification Report 
says ‘RESULT:ERROR’.There is probably temporary noise or static on the line. Try sending the fax again. 
If you are sending a PC Fax message and get ‘RESULT:NG’ on the Transmission 
Verification Report, your machine may be out of memory. To free up extra 
memory, you can turn off fax storage (see Turning off remote fax optionson 
page 59), print fax messages in memory (see Printing a fax from the memoryon 
page 43) or cancel a delayed fax or polling job (see Checking and cancelling 
waiting jobson page 37). If the problem continues, ask the telephone company to 
check your telephone line.
If you often get transmission errors due to possible interference on the telephone 
line, try changing the Compatibility setting to Basic(for VoIP). (See 
Telephone line interferenceon page 122.)
Vertical  black  lines  when  sending. Black vertical lines on faxes you send are typically caused by dirt or correction fluid 
on the glass strip. (See Cleaning the scanneron page 141.)
Handling incoming calls
DifficultiesSuggestions
The machine ‘Hears’ a voice as a 
CNG Tone.If Fax Detect is set to on, your machine is more sensitive to sounds. It may 
mistakenly interpret certain voices or music on the line as a fax machine calling 
and respond with fax receiving tones. Deactivate the machine by pressing 
Stop/Exit. Try avoiding this problem by turning Fax Detect to off. (See Fax 
Detecton page 41.)
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Fax Receive 
Code [default setting is (l 51)]. When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Caller ID,  Voice Mail, an 
answering machine, an alarm system or other custom feature on a single 
telephone line with your machine, it may create a problem sending or receiving 
faxes.
For Example: If you subscribe to Call Waiting or some other custom service and 
its signal comes through the line while your machine is sending or receiving a fax, 
the signal can temporarily interrupt or disrupt the faxes. Brother’s ECM feature 
should help overcome this problem. This condition is related to the telephone 
system industry and is common to all devices that send and receive information 
on a single, shared line with custom features. If avoiding a slight interruption is 
crucial to your business, a separate line with no custom features is recommended.
