If the error message, Unknown device appears, this can indicate that there is not adequate power and the PC can not identify the printer correctly. Verify that there are no extension cables and that the power cable is no longer than five meters. Reseat the power cables.
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.
This issue can be caused if any of the following situations exist: The currently loaded USB driver has become unstable or corrupt. Your PC requires an update for issues that may conflict with a USB external hard drive and Windows. Windows may be missing other important updates hardware or software issues.
The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
Select Start , then select Settings > Devices > Printers & scanners . Scroll down to Related Settings and select Print server properties. Select the Drivers tab, and see if your printer is listed. If it is, you`re all set.
In the Windows Settings search box, type “Printer,” then select Add a printer or scanner. In the Printers & scanners page, select Add a printer or scanner. Select your printer when you see it appear, then follow any additional instructions to install the printer driver.
Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
If you see an “unknown accessory detected near you” message (or similar), it means there`s an item compatible with the Find My network that might be traveling with you. If so, its owner may be able to see your location. You should look to see if something you`re borrowing has such a device attached.
