Lenovo LJ2400 print ready light is on, why is there no response?

The reasons are as follows: 1) First of all, troubleshoot the printer hardware connection, check whether the printer cable is correctly and effectively connected to the computer, check whether the power cord is correctly connected, and whether the power supply is normal.

2) It is possible that the printer is not the default printer. Sometimes Windows will also make a virtual printer, users need to start by clicking the Start Settings printer, check if there is a small black hook on the icon of the printer currently in use, and then set the printer as the default printer.

3) Another possibility that the printer is not printing is because of a computer malfunction. The way to check the hard disk space is to right-click on the hard disk icon where Windows is installed in "My Computer", select "Properties", check the hard disk space in the "General" tab, if the remaining space on the hard disk is less than 10MB, you must delete some useless files.

4) Check whether the current printer status is set to pause printing, if the printer is in the pause printing state, it is impossible to complete the printing task. The solution is to right-click the printer icon in the "Printer" window, check if there is a small hook on the "Pause Printing" option in the drop-down menu that appears, and select the "Pause Printing" option to cancel the pause printing option to resume normal printing.
