SYSTEM ERROR E100

This error code is dealing with the laser not being detected by its sensor. Check to see if the tab on the drum hasn't been bent or broken off, this pushes the laser shield out of the way so the laser can write to the drum. Lasers don't usually go out.

Hi carolyn ,
I am a professional canon service eng . My Name Is D K Kumar . e100 is not related to toner at all . it is the indication that the develper unit has not been detected . remove the left side cover . you will be able to see the top of the develpoer unit. On the left top portion of the developer unit u can see a white coloured accuvator . it is a small white plastic piece ..whhen the side door is closed te white piece should get pressed or should move forward . if the moving action is not happening then the m/c will give u E100 error. in your case the reasons /problem could be :
!) The spring connected to the white plastic accuvator is missing or spring action is not happening.
2) the white accuvator it self is broken or missing.
3) the plastic stick /piece which protudes from the side door and pushes the accuvator is broken.
4)lastly you have not closed the side door properly or not closed at all.
Carolyn if u r able to understand my above tips thn u can do it your self , if not call a your local canon enginer.
best of luck God Bless u

P.S. Carolyn if my solutions have helped u then i request u to kindly reply to me at my enail id: [email protected]

toner cartridge problem! check the actuator from the drum cartridge! maybe broken.....

How many copies do you have? If over then 55000 change the drum unit.

But it can also be the laser trouble.

wich system error?Is it 001, E100, E019?

For all copiers machine the 000 malfunction code is the main motor problem.Remove the fusing unit,developer unit,duplex unit to see the blocage .

hi there

first replace the drum (i.e the photoconductive cylinder)
I wish you solve the problem.

thank you and not forget to vote me any how.

Most likely, the tab on the rear side of drum unit has broken off. Thus causing the Lazer Shutter not to open. There are 3 or 4 other possibilities other than replacing the drum unit.

Hi, do you have an error message like E100 ? Please be specific.
