There are 2 primary paper sensors. One is the registration sensor where the paper feeds in, the second is associated with the fuser unit.

The first sensor is located under a cover under the transfer unit.
i) Open the door
ii) Lift out the transfer unit (Q3964A)
iii) Locate the black plastic cover plate with a small green flap in the centre. This assembly is directly under where the transfer unit was installed.
iv) There are 2 shiny screws that secure this cover plate. Carefully remove these screws.
v) Lift out the black cover plate by lifting the left section up first which allows the right section to come clear of gears.
vi) Check for paper obstructing the small movable lever under the cover plate.

vii) To reinstall the cover plate, insert the right hand side down first and line up with the mounting holes.

I can supply photos if required.

I take it you have installed a new toner???? Do oyu know the last time the drum & developer unit was replaced?? It is sold as a unit with the developer in the unit. It is a customer part to replace. If these parts were replaced resently, the problem could be in the toner holding unit that you put the toner bottle into... There has been some up dates to that unit > they improved the fin's that moves the toner into the developer unit... Good Luck

Open the front cover and locate the waste toner bottle. Empty it out and see if that corrects the problem. If that doesn't work, clean the bottle after emptying it. If the doesn't work, replace the waste toner bottle with a new one.

How does the copy quality look?

Hello!
Changing the Drum does not affect the scanner settings.
You can print because your PC (computer) can see your machine but for scanner is the oposit. The machine must see your PC.
I think that in this machine you have an SD card with the scanner funtion. Try to take it off and then put it on again. (the SD card is on its side. In the controller box)

If you still have any doubt reply to me.

Hello,
it could be two possible solutions...
First, the toner hopper/holder is clogged with toner and the toner doesn't go trough. To solve these vacuum and clean the bottle holder and handle mechanism that grabs the bottle.

Second, check if the toner motor turns. Open the cover, in sensor holes put piece of paper to trick them and see if the toner motor is turning. If not turning replace the motor.

Hope that helps!

Hi chro,
Send me an e-mail and I will send you the whole manual. I will give you my email address now,but it will look funny because "fixya" has an email filter to make sure we can't do what we are gonna do. jdh6211#####comcast#####net. If you can figure it out you win. I'll be watching. But you DO indeed have some fine tuning to do. Service mode and all that.

That is a polygon motor error.
This motor is from the Laser Unit. Probably you have to change it.
If you do not have technical training i advise you to call your provider.

sc990 has many reasons first drum unit defeactive and software on machine sluggish

Polygon motors are not serviceable items.

If the motor won't turn unless forced then you really need to get it replaced.
The bearings inside the motor can wear out causing excessive noise or seizure.

hope this helps
