Hi, I will be glad to help with the issue.
Over time, the rollers become worn and can either be replaced or a new printer must be purchased.
If the printer is under warranty, you can have the parts replaced. Otherwise, the cost to repair the rollers might be about the same as a new printer.
Check to see if the printer is under warranty first. If not, the rollers are too worn to pick up paper properly and eventually loose the traction.
Do you mean that it works after you clean the rollers for a while or continuously?
That might be an issue with a broken gear or motor not working properly.
It's hard to tell unless you get a printer service technician to open up the printer and inspect the parts.
At that point, it will still cost about the same as a new printer.
I will open the question so other experts can help.
