If you are having difficulty with your machine
If you think there is a problem with the way your faxes look, make a copy first. If the copy looks 
good, the problem is probably not your machine. Check the chart below and follow the 
troubleshooting tips.

DIFFICULTYSUGGESTIONS
Printing or Receiving Faxes
 Condensed print 
 Horizontal streaks
 Top and bottom of sentences are  cut off.
 Missing lines Usually 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 quality on page 11-15.
Vertical black lines when receiving Sometimes you may see vertical streaks/black lines on the faxes you receive.  Your machine’s primary corona wire may be dirty, or the sending party’s fax 
scanner may be dirty. Clean your primary corona wire (See  Cleaning the corona 
wire  on page 11-23), or 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 
Setting the Paper Size  on page 2-5.) Make sure that auto reduction 
menu setting is turned on. (See  Printing a reduced incoming fax (Auto Reduction)  
on page 4-4.)
Phone Line or Connections
Dialling does not work. Check for a dial tone. Change  Tone/Pulse setting. (See  Tone or Pulse  on page 
5-4.) Check all line cord connections. Check power cord connection. If an external 
phone is connected to the machine, send a manual fax by lifting the handset of the 
external phone and dialling the number. Wait to hear fax receiving tones before 
pressing  Start.
The machine does not answer 
when called. Make sure the machine is in the correct receiving mode for your setup. 
(See 
Basic sending operations  on page 3-4.) 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 there is no ringing when you call your machine, ask your 
telephone company to check the line.

Sending Faxes
Poor fax send 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 scanner  on page 11-21.)
Transmission Verification Report 
says ‘RESULT:NG’ or 
‘RESULT:ERROR’. There is probably temporary noise or static on the line. Try sending the fax again.
(MFC-7225N only)
If you send a PC FAX message and get ‘RESULT:NG’ on the Transmission 
Verification Report, your machine may be out of memory. To gain extra memory, 
you can turn off Fax Storage (See 
Turning off Remote Fax Options on page 6-3), 
print fax messages in memory (See  Printing a fax from the memory on page 4-4) 
or cancel a Delayed Fax or Polling Job (See  Cancelling a fax in progress on page 
3-8). If the problem continues, ask the telephone company to check your phone 
line.
If you frequently get transmission errors due to possible interference on the phone 
line, try changing the Compatibility setting to  Basic. (See Compatibility  on page 
11-19.)
Vertical black lines when sending. If the copy you made shows the same problem, your scanner is dirty.  (See Cleaning the scanner  on page 11-21.)
Handling Incoming Calls
The machine ‘Hears’ Voice as 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 calling fax machine 
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 Detect  on page 4-3.)
Sending a Fax Call to the machine. If you answered at the machine, press  Start and hang up immediately. If you 
answered on an external or extension phone, press your Fax Receive Code 
(default setting is ( 51). When your machine answers, hang up.
Custom  features  on  a  single  line. If you have Call Waiting, Call Waiting/Caller ID, Voice Mail, an answering machine,  an alarm system or other custom feature on a single phone 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.
Menu Setting Difficulties
The machine beeps when you try to 
access the Setup Receive and 
Setup Send menus. If the Fax   key is not illuminated, press it to turn on Fax mode. The Setup 
Receive setting (
Menu/Set, 2 , 1 ) and Setup Send setting ( Menu/Set, 2 , 2) are 
available only when the machine is in Fax mode.
Copy Quality Difficulties
Vertical streaks  appear  in copies. Sometimes you may see vertical streaks on your copies. Either the scanner or the  primary corona wire is dirty. Clean them both. (See  Cleaning the scanner on page 
11-21,  Cleaning the laser scanner window  on page 11-22 and Cleaning the drum 
unit  on page 11-16.)

intervals
Black Spots at 78.5 mm  intervals
Cleaning the drum unit
Dust, paper powder, glue, and so on may stick to the surface of the photosensitive 
drum (OPC) and cause black or white spots to appear on printed documents.
Make a few copies of a blank, white sheet of paper. (See  Making multiple copies 
on page 8-2.)
If you still see the spots on printed documents after making multiple copies, clean 
the drum unit as follows:
1 Remove the drum unit and toner cartridge assembly, and then remove the toner  cartridge from the drum unit.
2 Position the print sample in front of the drum unit so you will know the exact  position on the drum that is causing the poor print.
3 Turn the black gear on the drum as you check the surface of the OPC drum. Do not touch the OPC drum with your fingers.
4 When you find the substance on the drum surface that matches the print  sample, gently  dab the surface of the OPC drum with a cotton swab that is lightly 
dampened with isopropyl alcohol.
Do not  use a scrubbing or wiping motion because this might damage the 
drum.
Do not try to clean the surface of the OPC drum with a sharp object, such as 
a ball-point pen, because this might cause permanent damage to the drum 
unit.
If the print quality still has not improved you need to install a new drum.
