Why does it feed paper without printing?

SOURCE: Paper not picking up and alarm light comes on/stays on

Hi, You have the right idea of cleaning the rubber rollers behind the tray, (if the paper will feed through once then we can eliminate the idea of a paper jam)unfortunantly, when the rollers get too worn out then cleaning is not effective. I work on alot of Brother 5140 printers which look very similar to this model, and we pull out the tray,take the pick roller off of the printer, pull off the rubber part of the roller and rotate it 180 degrees from it former position which gives it a new area of wear. Usually that's a pretty good fix, and it isn't too hard to do, just make sure to note how it was put together before taking it apart. Good luck.

Somewhere very close to where the paper feeds into the machine, you should be able to find a little piece of rubber. This is the separation pad (sometimes it's made of cork). Clean that, and you should start working again. If it works, then you'll eventually need to replace the sep pad, as cleaning is a temporary fix. You can buy that and the feed roller (they should be replaced together) here:

Testimonial: "Thank you for the feedback. We have cleaned the seperation pad as well as the pick up rollers. Lot of dust particles were found on the pickup pad."
