spray or organic solvent/liquids containing 
alcohol/ammonia to clean the inside or 
outside of the machine. Doing this may 
cause a fire or electrical shock. (For more

of paper in the manual feed slot until the 
front edge of the paper touches the 
paper feed roller. Wait until the machine 
automatically feeds the paper. When 
you feel the machine pull in the paper, 
let go.

slot. If it is not, the paper may not be fed 
correctly, resulting in a paper jam.
• Do not put more than one piece of paper  in the manual feed slot at any one time, as 
it may cause a jam.
• If you put paper in the manual feed slot  before the machine is in the Ready mode, 
an error may occur and the machine will 
stop printing.

Large spots on the printed pagesC
If your printout has coloured spots at 94 mm 
intervals, follow the steps below to solve the 
problem.
aTurn off the machine. Disconnect all 
cables, and then unplug the power cord 
from the electrical socket.
bFully open the top cover by lifting up on 
the handle (1).
 
IMPORTANT
When the scanner is open, you cannot

cSee the print sample to identify the 
colour causing the problem. The colour 
of the spots is the colour of the drum you 
should clean. For example, if the spots 
are cyan, you should clean the drum for 
cyan. Take out the drum unit and toner 
cartridge assembly of the colour causing 
the problem. 
 
IMPORTANT
• We recommend that you place the drum unit and toner cartridge assembly on a 
clean, flat surface with a sheet of 
disposable paper or cloth underneath it in 
case you accidentally spill or scatter toner.
• To prevent damage to the machine from  static electricity, DO NOT touch the 
electrodes shown in the illustration.
