There are two timings of replacing the developer unit:
• when the message display indicates 

TONER LOW 

n (n: 1, 2, 3)

. (The

remaining toner is sensed.)

• when the message display indicates 

REPLACE PARTS

DEVELOPER UNIT

. (The number of printed pages is counted.)

These messages are displayed to recommed you to replace the
developer unit. The actual replacement is entrusted to you. If you are
still satisfied with the print quality, you do not replace the developer
unit and can continue printing.
• press the 

 button when the printer stops with 

TONER LOW 

n

• just remember the recommendation when the printer displays

REPLACE PARTS

However, you must at least prepare a new developer unit.

When the printer first detects that toner in the developer unit is
short, the message display indicates 

TONER LOW 1

 and printing

stops. We recommend you to replace the developer unit for printing
formal documents. If you are satisfied with the print quality, press
the 

 button to continue printing. When the printer further

prints a certain number of pages, the message display indicates

TONER LOW 2

 and printing stops. If you are satisfied with the print

quality, press the 

 button to continue printing. When the

printer further prints a certain number of pages, the message display
indicates 

TONER LOW 3

 and printing stops. We recommend you to

replace the developer unit unless printing informal documents.
•

TONER LOW 

n

Toner low error message

Press Continue

(Printer stops with this message.)

•

READY

Toner low warning message

TONER LOW 

n

(Printer is ready for printing.)

After 

TONER LOW 3

, n is kept to 3 even if you continue printing

again and again.

If you change the toner low option from “Stop” to “Continue” with
the Config menu in setup mode, the printer does not stop even if a
toner low condition is detected.
