MX-M1100  TONER SUPPLY SECTION  J – 3

There are following two conditions for judging as Toner End. 
When one of them is satisfied, it is judged as Toner End. 
1) When the accumulated rotation time of the toner motor (TM1)

reaches 700sec from the toner near end timing. 

(This condition can be ignored by setting with the simulation.) 

(It corresponds to the print quantity of 15K with 6% density

documents.) 

2) When Toner Low is detected by the toner density sensor (TCS)

and Toner Near End is judged by the toner sensor (TNCA). Or

when the toner bottle is not installed. 

When Toner Low is detected by the toner density sensor (TCS) in a

state other than the Toner Near End condition, it is judged that

toner is not supplied from the toner hopper to the developing sec-

tion and that there is an abnormality in the toner hopper, displaying

the FD2-02 error and disabling the printing operation. 

When the power is turned ON under toner empty with no toner bot-

tle installed, the message to urge installation of the toner bottle is

displayed and no print job can be executed. 
When, however, in the normal state or in toner near end state with

no toner bottle installed, the message to urge installation of the

toner bottle but a job under execution is continued and a new job is

accepted.  

1) Open the front cover (a), and pull out the toner tray (b) slightly.

2) Remove the screw (a), and remove the cover (b).

3) Remove the blue screw (a), and remove the plate (b).
