TROUBLESHOOTING
CLEARING PAPER JAMS
Provided that you follow the recommendations in this guide on 
use of print media, and you keep the media in good condition 
prior to use, your printer should give years of reliable service. 
However, paper jams occasionally do occur, and this section 
explains how to clear them quickly and simply.
One of the main causes of paper jams is media that has been left 
in the cassette tray while the machine is in a high humidity 
environment (typically, in an unmanned office over a weekend).
Jams can occur due to paper misfeeding from a paper tray or at 
any point on the paper path through the printer or scanner ADF. 
When a jam occurs, the MFP immediately stops. If printing 
multiple pages (or copies), do not assume that, having cleared 
an obvious sheet, others will not also be stopped somewhere 
along the path. These must also be removed in order to clear the 
jam fully and restore normal operation.

1.If a sheet is well advanced out of the top of the printer, 
simply grip it and pull gently to  draw it fully out. If it does 
not remove easily, do not use excessive force. It can be 
removed from the rear later.

6. Put the cartridge down gently on to a piece of paper to 
contain any toner spillage.
  
CAUTION!
The green image drum surf ace 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 printer for longer 
than this, please wrap the cartridge inside a black 
plastic bag to keep it away from light. Never expose 
the drum to direct sunlight or very bright room 
lighting.

> To remove a sheet just entering the fuser , separate 
the trailing edge of the sheet from the belt, push the 
fuser pressure release lever (1) towards the front and 
down to release the fuser’s grip on the sheet, and 
withdraw the sheet through the drum cavity area. Then 
allow the pressure release lever to rise again.
  
NOTE
If the sheet is well advanced into the fuser (only a short 
length is still visible), do not attempt to pull it back. Follow 
step 12 to remove it from the rear of the printer.

10. Starting with the cyan image drum unit nearest the fuser, 
replace the four image drums into the drum cavity, 
making sure to locate them in the correct order.

    >Holding the complete assembly by its top center, lower 
it into place in the printer, locating the pegs at each 
end into their slots in the sides of the printer cavity.
11. Lower the printer top cover but do not press down to latch 
it closed yet. This will protect the drums from excessive 
exposure to room lighting while you check the remaining 
areas for jammed sheets.
12. Open the rear stacker  and check for a sheet of paper in 
the rear path area.

FAX PROBLEMS
The machine will not dial a telephone number :
Check the power cable and wall outlet. Make sure that the 
telephone line (not external telephone or handset) is connected 
to the LINE socket on the back of the machine. If an external 
telephone is installed, lift the handset and check for a dial tone. 
If there is no dial tone, there may be a problem with the 
telephone line. If there is a dial tone, the machine may be using 
the wrong dialling method (pulse or tone) for the region.
The display shows a communications error :
This alarm indicates any of a number of problems. The machine 
may be incompatible with the remote machine, or the remote 
machine may not be able to perform the function requested of it 
such as polling or confidential faxing. The remote machine may 
also be out of paper or experiencing a paper jam. Bad telephone 
line conditions can also cause communication errors. Try sending 
the fax again and check to make sure that the correct telephone 
number is being dialled. If a prefix number must be dialled to get 
an outside line, or if the call is  to an international destination, a 
pause may need to be entere d after the dial prefix or
