Is absent Block of the Manifestation or is drived activator of the sensor, sensor burns out seldom and can be unplugged (on the right at the top on block)

It can be dirty ID sensor it retires the image unit and it cleans it… This happens when mylar of the cleaning unit is damaged…

On the report where it shows the E-3 error, it should have a legend further down the page that shows what each error means. I think E-3 is "line busy," but check that legend to be sure.

Hello!

I believe that you closed all the doors properly...

Well, this may happen because off several things.

I can give you some tips (by steps):

- First you have to make sure that the toner bottle spins (if that doenst happen it could be a faulty clutch).
- Than you need to see if the tonner supply (the green handel that you place the toner) are good.
- After that you just have the TD sensor. This sensor is on the Developement Unit.

Well, i am just giving you a clue. If you do not have thecnical knoledge i advise you to call your provider.

See you, And good luck

1. Go to this code with "Clear Mode"+107+"Clear/Stop" hold for 5s.
2. Go to System Settings
3. Go to 5875
4. Check the setting of SP5875-001. If the setting is set to "1 (OFF)",change it to "0 (OFF)".
