Replacing the drum unit

Order Number: DR-150CL
Change Parts Drum message
Change Parts
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 158.)
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.
