Try connecting the product to your router, access point, switch, or hub with another Ethernet cable. Try printing from another computer on the network to see if the problem persists. If network communication was interrupted while starting Epson Scan, exit Epson Scan, and restart it after a few seconds.
The common causes of “General Error” are: Something in the path of the printhead (like bits of paper or something that`s been dropped in) Incompatible cartridges (Printer can`t/won`t recognise them) Autohead Cleaning & insufficient ink in cartridge(s) [PX/TX700W <-> Artisan 837 models]
Check cables or wireless connection

Make sure that the printer`s USB cable is properly connected from the printer to your PC. If your USB isn`t recognized, see Automatically diagnose and fix Windows USB problems. Check the wireless connection (for wireless printers).

Restart the printer and try again. Unplug the printer from an outlet. You can plug it back in again to see if it works this time. Check if the printer is properly set up or connected to your computer`s system.
There is a possibility that it didn`t properly click into the designated slot. If this is the case, you should lift the cover and double-check in order to verify that the cartridge is clicked into place. Otherwise, it would not be possible for the printer to detect it.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.
EPSON printer utilities allow you to check the current printer status and to perform some printer maintenance from your computer. To use the utilities, click the Utility tab in the printer software, then click the button for the utility that you want to use.
Open Control Panel > Hardware and Sound > Devices and Printers. Right-click the printer and select Properties. Look in the Web Services tab for your IP address if only three tabs appear. Alternatively, look in the Ports tab for your IP address if five tabs appear.
Note: If you don`t see your printer, make sure your Android device and printer are connected to the same wireless network and tap Search at the bottom of the screen to search again. If you still don`t see your printer, you can connect manually to the printer from the Manual IP tab or tap Wi-Fi Direct Setup.
Make sure the mobile device`s Bluetooth is turned on. Check to see if the printer`s Bluetooth light is pulsing. If not, enable Bluetooth on the printer and try pairing with the printer again. Check if the printer is communicating with another mobile device.
Restart the printer and the computer or mobile device to clear possible error conditions. Restore Wi-Fi setup mode. Most printers with a touchscreen display or menu: Open the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.
