“Printer gets the papers from the manual feed plate instead of picking up from one sheet”- hp printer support online
The pad that isolates the paper has likely exhausted and should be supplanted. You can arrange and introduce another pad without sending the printer out for fix. It is additionally conceivable that the paper is wet because of moistness. Ensure the paper is appropriately put away and that it is “fanned” before placing it into the printer.
We at hp printer support online recommend you to regularly clean your paper input tray. Apart from that it is advisable that you use standard sized papers as prescribed by HP.
