Hi krupaldo
I understand you are getting the message to load the paper tray.
I will be happy to assist you with this.
Check the print cue to make sure it is empty. Go to Solution two: Restart the computer and check the print queue.
Make sure the paper tray isn't overfilled or enough paper loaded.
I have provided the manual for the printer. Go to page 51 for loading the paper tray.
Make sure the printer settings are set to A4 paper size.
Go to start, devices and printers, right click the printer, left click printer properties, click the Paper/Quality tab, select the A4 for the paper size.
In the application you are printing from select the paper size as A4 also.
You might need to reset the country definition to a place where they have A4 paper. (example not the US)
If you need more assistance just let me know.
