3.Press the cover release (a) and open the MFP’s top cover (b) fully.
4.Note the positions of the four cartridges.
It will be necessary to remove the four image drums to gain access to the paper path.
5.Holding it by its top centre, lift the cyan image drum, complete with its toner 
cartridge, up and out of the printer. 
6.Put the cartridge down gently onto a piece of paper to prevent toner from marking 
your furniture and to avoid damaging the green drum surface.
WARNING!
If the MFP has been powered on, the fuser will be hot. This area is 
clearly labelled. Do not touch.
1. Cyan cartridge 2. Magenta cartridge
3. Yellow cartridge 4. Black cartridge
CAUTION!
The green image drum surface at the base of the 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.

7.Repeat this removal procedure for each of the remaining image drum units.
8.Look into the MFP to check whether any sheets of paper are visible on any part of 
the belt unit.
(a) To remove a sheet with its leading edge at the front of the belt (1), carefully lift 
the sheet from the belt and pull it forwards into the internal drum cavity and 
withdraw the sheet.
(b) To remove a sheet from the central area of the belt (2), carefully separate the 
sheet from the belt surface and withdraw the sheet.
(c) To remove a sheet just entering the fuser (3), separate the trailing edge of the 
sheet from the belt, push the fuser pressure release lever (4) towards the front 
and down to release the fuser’s grip on the sheet, and withdraw the sheet 
CAUTION!
Do not use any sharp or abrasive objects to separate sheets from 
the belt. This may damage the belt surface.

through the drum cavity area. Then allow the pressure release lever to rise 
again.
9.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 centre, lower it into place in the MFP, 
locating the pegs at each end into their slots in the sides of the MFP cavity.
10.Lower the 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.
11.Open the rear exit tray (5) and check for a sheet of paper in the rear path area (6).
Pull out any sheets found in this area.
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 the next step to remove it from the rear 
of the MFP.

by the fuser. In this case raise the top cover, reach around and press down on the 
fuser pressure release lever (7).
12.If you are not using the rear exit tray, close it once paper has been removed from 
this area.
13.If your MFP has a duplex unit installed, press the cover release at the centre of the 
unit, open the cover and remove any sheets in this area, then close the cover.
14.Lift the front cover release and pull open the front cover.
15.Check inside the cover for sheets in this area and remove any that you find, then 
close the cover.

16.Pull out the paper tray and ensure that all paper is stacked properly, is undamaged, 
and that the paper guides are properly positioned against the edges of the paper 
stack. When satisfied, replace the tray.
17.Close the top cover and press down firmly at both sides so that the cover latches 
closed.
18.Gently lower the scanner.
When the jam has been cleared, if Jam Recovery is set to ON in the System Configuration 
Menu, the MFP will attempt to reprint any pages lost due to paper jams.

FAX PROBLEM CHECKLIST
If a problem occurs, read through the list of problems and solutions before calling for 
service.
The MFP 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 MFP may be using the wrong dialling method (pulse or tone) 
for the region. If alternating tones are heard instead of dialling pulses and the region uses 
pulse dialling, change the call parameters (see “Initial set up” on page 50).
The display shows a communications error. This indicates any of a number of problems:
>The MFP 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.
>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 entered (use the Pause key) after 
the dial prefix or 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 speed dial key, and then change the 
parameters for that key (see “Advanced set up” on page 50).
>Lastly, either the local or remote machine may require servicing. Try sending a fax 
to another location to check the local MFP.
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 fax quality and density settings (see “Advanced 
operation” on page 66). 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.
Fax sent but received message was completely blank. Make sure that the document 
is loaded correctly before faxing; with text face UP in the ADF or face DOWN on the glass.
Image of received fax is very poor. Try making a copy of a document on the local 
machine to make sure it is working properly. If there is still a problem, contact the person 
sending the fax and ask them to change their fax quality and density settings. Ask the 
person to make a copy of the document on their machine to ensure that it is working 
properly. Then ask them to send the fax again.
Dialling was tried with a Speed Dial number but nothing happened. Make sure  that 
the Speed Dial number being used is programmed correctly.
Local MFP will not answer the telephone or receive faxes. First check to see that the 
power cord is connected properly. Also check the reception mode setting of the machine. 
This MFP will not receive faxes automatically if the manual receive mode is enabled (see 
“Manual receive” on page 54).
Documents received are light or have vertical streaks on them, and MFP is not out 
of toner. Gently wipe the lens surface of the MFPs LED array, and then check to see if the 
machine is working properly (see “....the LED head” on page 92). If the MFP still does not 
work properly, remove the image drum (see “Image drum replacement” on page 84
), tap 
the toner cartridge, and slowly swing it 20 to 30 degrees vertically several times. Be careful 
not to let the toner leak from the cartridge. If this does not work, the image drum unit may 
need to be replaced. Contact your supplier to get a replacement.

MFP is set for delayed transmission but it did not send. Check the display to make 
sure that the MFP is set to the correct time and date (see “Initial set up” on page 50).
MFP will not poll a remote machine. Call the person at the remote machine and make 
sure that they have loaded documents and that their machine is set to polling transmission 
mode.
MFP 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 MFP (see “Connecting to a PBX” on page 53).
MFP always answers before its possible to use the external telephone. If an 
external telephone is connected, change the MFP’s ring response setting (see “Advanced 
set up” on page 50).
Faxes received sometimes 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.
