Brother MFC-8840d ADF feed problem

The ADF in my Brother MFC 8820D will not feed a page through

Doc jam error usually means a jam in the adf (auto doc feed) when feeding a fax or doc to copy.

The most common reason brother mfc,s of this configuration have doc feed issues is believe it or not the hinge that operates the lid/adf, specifically the left side one (looking from the front). Inside the hinge there are two springs exerting tremendous force on the hinge (that enables the lid to stay up by itself) however this force eventually slowly breaks the fulcrum point of the hinge which leads to the lid not closing properly which means a sensor under the lid does not activate properly resulting in the adf stopping and resulting in the machine registering a jam. the difference between the sensor activating or not can be as little as a millimeter and is not often disernable. the hinge needs replacing by a techo.

the other reason could be you just have dirty adf feed rollers, clean them with a cotton rag dipped in metho, open the adf lid and give the rollers a scrub. the rollers should have 'tread' on them similar to a tyre, if not they are worn and need replacing.

One other possibility is there may be a paper fragment left over from a jam removal still caught in the paper path and activating a sensor activator that tells the machine paper is coming or going. most commonly in the section where the paper is looping on its return journey back out of the adf, open the adf lid, have a look with a torch and see how you go.

With my Brother 8840D I have had paper jams that when cleared would not delete from the display nor would the machine operate until I unplugged the machine for around eight hours. I guess it is a sort of reset or reboot.

One or more of the gears on the drive train is damaged, you wil need to take the Printer to a service centre to be repaired.

Open the document feeder and look for an obstruction.

Clean the roller and pad with isopropyl alcohol.

Also look for a switch actuator trapped down or knocked off.

change paper pick-up roller & paper stop roller in ADF

Is this through the ADF (top feeder) or from the paper tray? Either one can have some build-up on the paper feed rollers and would have to be cleaned.

i want printer driver for winxp

Like a worn running shoes, the paper feed roller of the Automatic Document Feeder (ADF) have lost it's traction and has to be replaced or cleaned. Paper just slids and doesn't picked up properly without that little push. Professional servicers use a cleaner specifically designed for rubber rollers. However, YOU CAN get extra miles on it by dabbing a Q-tip in warm water and cleaning the paper feed roller on the ADF. Like all eletrical devices, the unit has to be turned off and unplugged before working on it. Take all precationary measures and goodluck.
