Samsung CLP300 laser printer does not take paper I have to help it
I have a clp300 printer that is almost new. I use it for few pages/month.
Unfortunately the printer does not take the paper sheet from the paper tray.
I can improve the situation in two ways:
1) opening and closing again rear door sometimes solves the problem but for few sheets.
2) if I "help" the printer pushing the sheet with my hand it always take it and print it.
It seems a problem of the first stage of the sheet input.
What can I do?
