Note Note
•
Make sure that the paper is straight and in the correct position on the manual feed 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 pages
If your printout has coloured spots at 94 mm intervals, follow the steps below to solve the problem.
1
Turn off the machine. Disconnect all cables, and then unplug the power cord from the electrical socket.
2
Fully open the top cover by lifting up on the handle (1).

CAUTION IMPORTANT
When the scanner is open, you cannot open the top cover.
3
See 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.

CAUTION 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.

Push down the green-labelled lock lever (1) and take the toner cartridge out of the drum unit.

CAUTION IMPORTANT
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.

Put the print sample in front of the drum unit, and find the exact position of the poor print.

Turn the drum unit gear by hand while looking at the surface of the OPC drum (1).

When you have found the mark on the drum that matches the print sample, wipe the surface of the OPC drum with a dry cotton swab until the dust or glue on the surface comes off.

CAUTION IMPORTANT
DO NOT clean the surface of the photosensitive drum with a sharp object.

Put the toner cartridge back firmly into the drum unit until you hear it lock into place.
