Cleaning the corona wire

We recommend placing the drum unit and 
toner cartridge assembly on a cloth or large 
disposable paper to avoid spilling and 
scattering toner.

1

Open the front cover and pull out the 
drum unit and toner cartridge assembly.

2

Clean the primary corona wire inside the 
drum unit by gently sliding the blue tab 
from right to left several times.

3

Return the blue tab and snap it into the 
Home position (

ā–¼

).

4

Reinstall the drum unit and toner 
cartridge assembly in the machine.

5

Close the front cover.

Replacing the toner cartridge 
(TN-350)

The toner cartridge can print 

up to

 2,500 

pages. When the toner cartridge is running 
low, the LCD shows 

Toner Low

. Actual page 

count will vary depending on your average 
type of document (i.e., standard letter, 
detailed graphics).

Note

It is a good idea to keep a new toner cartridge 
ready for use when you see the 

Toner Low

 

warning.

Discard the used toner cartridge according to 
local regulations, keeping it separate from 
domestic waste. Be sure to seal the toner 
cartridge tightly so toner powder does not 
spill out of the cartridge. If you have 
questions, call your local waste disposal 
office.

We recommend that you clean the machine 
and drum unit when you replace the toner 
cartridge. (See 

Cleaning the laser scanner 

window

 on page 11-22 and 

Cleaning the 

drum unit

 on page 11-17.)

CAUTION

If you do not return the blue tab to the 
Home position (

ā–¼

), your printed pages 

may have vertical black stripes on them.
