9.Remove any sheets of paper as follows: 
>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 forwar ds into the internal drum cavity and 
withdraw the sheet.
> To remove a sheet from the central area  of the belt, carefully separate the sheet 
from the belt surface and withdraw the sheet.
> To remove a sheet just entering the fuser,  separate the trailing edge of the sheet 
from the belt, push the fu ser 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.
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 centre, lower it into place in the printer, 
locating the pegs at each end into their  slots in the sides of the printer cavity.
CAUTION!
Do not use any sharp or abrasive objects to separate sheets from 
the belt. This may damage the belt surface.
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.

FAX PROBLEM CHECKLIST (MC360)
If a problem occurs, read through the list of problems and solutions before calling for 
service.
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. If alternating  tones are heard instead of dialling pulses and 
the region uses pulse dialling, change the call parameters ( “MF(Tone)/DP(Pulse)” on 
page 41 ).
The display shows a communications error:  This 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 ca use 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 after the dial prefix or 
international dialling code to tell the mach ine to wait for a dial tone. If there are 
frequent problems communicating with a particular remote machine, try 
programming the number into a speed dial  key, and then change the parameters for 
that key.
> Lastly, either the local or remote machin e 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 changi ng the fax density settings (see “Density” on page 36). 
Copy the document on the mach ine 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 messa ge 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 thei r fax quality and density settings. Ask the 
person to make a copy of th e 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/Gro up 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 # or * before entering the number.
Documents received ar e light or have vertical streak s on them, and machine is not 
out of toner:  Lift the top cover and gently wipe th e lens surface of the machines LED 
array. Then check to see if the tone r or image drum need replacing (see  “Replacing 
consumable items” on page 97 ).
Machine is set for delayed tran smission 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” on 
page 40 ).

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 mu st be programmed for PBX operation before 
it will work with a PBX (see  “Connecting to a PBX” on page 46 ).
Machine always answers before it’s poss ible to use the external telephone:  If an 
external telephone is connected, increase  the machine’s ring response setting (see “Ring 
Response” on page 41 ).
Faxes received someti mes look distorted: If the document received is wider or longer 
than the paper loaded in the  paper tray, the machine automa tically 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.
