I have a multifuctional konica pagepro 1490mf printer which is not picking papers in the document feeder

pleas check the driver settings, maybe there is a setting fit to paper or something.

Go to control panel, printers, right click the pagepro and select properties. Click the ports tab and make sure that the port is set to a USB port. This did it for me.

Open c:\windows\system32
find a file called MSTMON_Q.EXE

right click and rename the file to anything with a file extension .exe, I named it MSTMON.EXE

Create a shortcut to this new file in case you need it in the future and put the shortcut on your desktop

also, write the original name of the file down or put it on notepad, in case you want to change it back.

restart windows

have you tear the paper when removing? there is a small paper left still inside the paper path. open the back side and the top part and check for small paper. I hope that will solve your problem and if think the problem still there the problem is one of the paper sensor actuator is broken or out of place.

Need to set A4 size default on the printer driver itself.
Go to Printers and Faxes / Konica Minolta 2490MF right click/ Printing preferences /
Create a "Easy Set" with a new name. Set all paper sizes to A4. Save the new settings to the new Easy Set.
Click apply.

should be o.k.
