Make sure that both your computer and your Lexmark printer are connected to your network. Restart your printer. In some cases, a simple restart can fix the issue. Unplug the printer and check if there is any paper stuck in the machine, and if the toner is installed correctly.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
If the “load paper” error pops up during printing and your paper tray is full, it`s very possible that your paper feed rollers are worn or dirty. Paper feed rollers can wear down over time or accumulate dust and paper fibers.
Common Causes of Lexmark Printer Offline Status

Some of the common causes include: Connectivity issues – If your printer is not connected to the network or the connection is weak, it may show an offline status. Outdated drivers – If your printer drivers are outdated or corrupted, it may cause the printer to go offline.

Start by checking your hardware

If you`re using a wired printer, make sure that the printer cable is properly connected from the printer to your PC. For wireless printers, check the wireless connection. Make sure the printer`s wireless option is turned on and available.

1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

If your printer is showing an offline message, it means it`s having a hard time communicating with your computer. There can be several reasons for this, from connectivity issues to a fault with your printer. Whatever the reason, there are several checks you can do to determine which issue you`re facing.
The problem usually has to do with your printer`s Wi-Fi or its connection to your computer. All sorts of issues can arise—your PC and printer aren`t communicating or an incorrect setting may have forced your device to appear offline.
Make sure that both ends of the USB cable are correctly inserted into the computer and the printer. Try disconnecting and reconnecting the USB cable at both ends. Disconnect the printer and the computer and reconnect them. Try another USB port if available.
