Drum
The machine uses a drum unit to create print images on paper. If the LCD shows Change Parts Drum, the drum unit is near the end of its life and it is time to buy a new one.
Even if the LCD shows Change Parts Drum, you may be able to continue printing without having to replace the drum unit for a while. However, if there is a noticeable deterioration in the output print quality (even before Change Parts Drum appears), then the drum unit should be replaced. You should clean the machine when you replace the drum unit. (See Cleaning the laser scanner windows on page 154.)
CAUTION
While removing the drum unit, handle it carefully because it may contain toner. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
Troubleshooting and routine maintenance
Note
The drum unit is a consumable item, and it is necessary to replace it periodically. There are many factors that determine the actual drum life, such as temperature, humidity, type of paper and how much toner you use for the number of pages per
print job. The estimated drum life is C approximately 17,000 pages. The actual number of pages your drum will print may
be significantly less than these estimates. Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum.
Replacing the drum unit
CAUTION
Wait to unpack a new drum unit until immediately before installing it. Put the old drum unit into the plastic bag.
HOT SURFACE
After you have just used the machine, some internal parts of the machine will be extremely hot. When you open the front or back cover of the machine, DO NOT touch the shaded parts shown in the illustration.
