Replacing the drum unit 
(DR-350)

The DCP uses a drum unit to create print 
images on paper. If the LCD shows 

Change Drum Soon

, 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 Drum Soon

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 Drum Soon

 appears), then the 

drum unit should be replaced. You should 
clean the DCP when you replace the drum 
unit. (See 

Cleaning the laser scanner window

 

on page 6-17.)

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 

up to

 12,000 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.

CAUTION

When removing the drum unit, handle it 
carefully because it contains toner. If toner 
scatters and your hands or clothes get 
dirty, immediately wipe or wash it off with 
cold water.
