Jamming while picking up from front tray

Probably it's the jammed paper that might caused the error. I suggest have it serviced by the technician. Be aware of the paper handling capacity of your machine to minimize jamming:

1. 1 Switch off the printer and disconnect the power supply. Allow any residual charge to fade away before putting your hands or metal tools inside the chassis.

2. Step 2 Pin down the exact location of the jam. The three hot spots for a jam are the paper tray, anywhere between the feed tray and the print carriage, or between the print carriage and the output tray.

3. Step 3 Take off the front paper tray if the sheet got stuck while it was still in the front area of the printer. If the sheet jammed here, you should be able to see most of the paper.

4. Step 4 Pull on the sheet with both hands and steady pressure. Do not tug as you might rip the paper, leaving a chunk of it deeper in the machine.

5. Step 5 Open the back panel to reach paper jammed between the feed tray area and the print carriage of the all-in-one printer. Carefully remove the jammed paper from the machine.

6. Step 6 Use the carriage access door to reach a jam further inside the all-in-one printer. You may need to move the print carriage out of your way to clear the jam.
Step 7 Return any access panels to their closed and locked positions. Plug your printer back in and flip the power switch

You probably need to clean the paper pickup roller above the paper tray. A clean cloth dipped in diluted kitchen detergent and a couple of drops of alcohol, will clean the rubber rollers. Stroke the cleaning cloth firmly from side to side all the way around all the rollers. Also clean the paper separation shoe (rubber pad) at the front of the paper tray. The last thing is to make sure your paper is dry. Damp paper sticks together

Every 120,000 pages, the paper feed rollers, fuser, transfer roller, and OPC belt cartridge should be replaced, usually by a trained techncian.
Fuser and OPC belt units are customer-replacable.

The multiple feeding of the paper into the printer is due to a worn paper separation pad. part no. LM0711001. If the machine is picking up the paper okay and the jams occur solely from multiple sheet feeding, then this part is probably all you will need. The steps required to access and remove & replace the separation pad unfortunately is about 10 steps. Better consult a tech.

Easy fix. Replace the pick up rollers. There cheap and easy to replace. It make perfect sense, bought at the same time and use the same amount then the pick up rollers are going to wear out causing paperjams at the same time.

Hi, i'd start with cleaning any rubber rollers in the paper path, if its picking multiple sheets and then jamming, it will need a pick roller and seperation pad, hope this is helpful ,M.

without some information about the kind of printer and the weight/thickness of the paper, try to supply more information in a comment if you can, this is a generic answer.
many printers have a paper thickness adjustment that helps ensure that only one sheet is picked up at a time, and that the sheet feeds accurately,
if two or more sheets are picked up there are jams as multiple sheets do not feed well, and may not even get out of the paper tray. If the printer is set for a thicker paper, the lead edge of thinner sheets may miss its aimed path and wrap around guides or rollers, jamming.
The makers web page, or the user guide if you still have it, often have FAQ on paper jams,

suggest you bring your orinter to the nearest authorised repair center. There might be parts to be replace
