My printer X3350 has trouble grabbing the paper from the paper tray. What can is the problem. I tried cleaning the grabber wheel. But it still won't grab the paper.

Problem:
The 'drop down paper grabber' gears are not turning, and the printer gives you an error saying to make sure there is paper in the printer.
All of the fixes on the internet are for working printers, and their approach is to clean the rollers if they are not grabbing the paper. They are assuming they are turning properly and the rubber grabbing wheels are wither dirty of dried out.
In my case, however, the gears were not turning, and so the rubber grabbers wheels were not turning, even though the whole 'paper grabber' unit was dropping down properly
Solution:
Just inside the paper loader tray, along the top, there is a metal rod. It is about 1 inch from the front.
The gears from the drop down paper grabber are supposed to meet a gear that resides on this rod and sort of floats on it. However, the gear on my printer slipped to the left, and was not making contact with the other gears.
You can gently put your finger on the gears as you do a copy command, and confirm this.
To fix the printer, I just slid the floating gear over to the right and into place, and the paper began feeding properly.
Why there is nothing to keep the gear in place is a mystery to me.

You can try cleaning the rubber wheels with alcohol. Sometimes they become covered in dust and won't grab the paper.

Maybe the problem is,the problem is with the mechanical paper grabbers inability to grab this type of paper.

Take the tray out and clean the rubber paper grabbers with alcohol. If this does not work they the paper pickup assembly will have to be replaced.

Remove the paper tray. Use a lint-free cloth dampened with rubbing alcohol (isopropyl) to wipe all around the black "rubberish" wheels right underneath the unit where paper tray goes. I learned that by calling Okidata.

The pickup rollers need cleaning or there is too much paper in the tray (paper lift spring not strong enough).
Clean the pickup rollers on the tray with Q-Tip / 70% alcohol ... or lens wipes (for glasses and monitor screens).
Use less paper in the tray for now.

See page 55 for cleaning the media roller.

If the wheels do not rurn then it is either a clutch or board problem.

you may have to take the clutch apart and clean it, also some clutches have a felt pad on them after years they turn into sticky, clean off.

rollers can use a little cleaning sounds like..

Sounds very similar to my problem. In my case the Feed Switch ( Button on front console) got changed to load from the front tray, although paper was in back. I hit feed switch and changed to rear tray. Now it loaded and printed.
