i am getting error on my Epson WorkForce Pro WF-4720 printer scanner error 9923 / 033007
I see that you are facing an error on your Epson WorkForce Pro WF-4720 printer scanner error 9923/ 033007. I know how frustrating it can be, unable to scan from your Epson 4720 printer with an Epson printer scanner error. The Epson error code 9923 usually shows up when there is a miscommunication with the devices that are connected with it, the cables connected to the printer, or due to a corrupted Epson printer driver. The fixes to these Epson scan error 9923 are simple and I have some troubleshooting steps that you could try.
1. Shutdown the scanner and start up again
When the epson printer scanner error pops up, turn off the scanner and disconnect the cables that are connected to the scanner. Wait for a minute after the cables are removed and then plug in the cable(s) to the scanner, now power up the scanner. If this step did not resolve the Epson scan error 9923, proceed to the next step.
2. Remove the printer from System Preferences (Mac) / Devices and Printers (Windows).
Delete the Epson printer in the Devices and Printers (Windows)/ System Preferences (Mac). Search and delete any software/apps related to Epson Scanner/Printer that you may have installed. Restart your Epson scanner and add the printer from the Devices and Printers (Windows)/ System Preferences (Mac). if the Epson scanner error 9923 still persists, continue with the next step.
3. Reboot your wireless LAN Router (Wi-Fi)
The Epson error code 9923 is also caused due to a routing issue. This could probably be due to signal interference from microwave ovens, cordless phones, wireless video cameras and fluorescent lights and power line cables. Make sure the Epson scanner is kept at a good distance away from all the mentioned items. To reset the interference, switch off your home/ office router, wait for a couple of minutes and restart the router.
4. Reinstallation of the Operating System.
This step should be kept as the last if none of the troubleshooting steps work for Epson scanner error 9923.
The Epson scan error 9923 is a very common error for Epson 4720 printer. So for users who use this particular printer, it is advise to always update the scanner software and the Operating Software whenever it is available. I have had this happened, a very similar issue with my HP 4720 printer with my Mac, no communication with the printer and the computer. Only after a Operating System reinstallation i was able to resolve the problem.
