Paper jams to one side

yes first u open all cover of your printer carefully.than u clean all sensor of printer,,if there r dust in sensor than its give error msg,

Hello

Check within your paper feeder rollers there might be something stuck inside it like paper clips, coins or anything small and solid. If you can find way to open the printer without braking it, that would be nice.

Hope this helps.

i have the same problem i hate it

Sounds like something has fallen into the paper path. Use a flashlight and small mirror to look down the slot where the paper goes. You may have to use a straightened paper clip or the like to help remove the obstruction.

That will give you everything you need.

Most likely something is in the paper feeder try turning it upside down and shaking it to see if anything should drop out,you need to remove whatever is in there before it works ok again..

clean up the roller that picks the paper up.

This is definitely a mechanical problem. You might want to at least partially take the printer appart and inspect it very thoroughly if you haven't done so yet. Did you have any paper jams before? Sometimes when you remove a paper jam the sheet rips and you end up with some shreds of paper lodged in the printer mechanism causing more jams. Another possibility might be cracked or bent paper guides, or simply dirty rollers (these you can clean with alcohol).

i did exactly as iamzwalrus said and it fixed.go with that if nothing eles works.

You need to reset the printer!
