Do you mean the Epson L382? If so, are the two lights blinking in an alternating pattern? Then the blinking lights indicate that one of the printer's ink absorbing pads are near or at their end of life. This has nothing to do with the scanner problem. See page 71 of the manual available on the product support page: https://www.epson.eu/en_EU/support/sc/epson-l382/s/s1506
. It's messy to replace the ink absorbing pads; most manufacturers want you to replace the all-in-one if the printer is out of warranty when these pads are full of waste ink.
Scanning requires two-way communication between the computer and the printer. Does the scanner work if you try to launch the scan from the computer? If so, then check if the Epson scan monitor is running and properly set up to respond to a button press on the L382.
If the scanner isn't found, what OS (including update/SP) is installed? The Epson support indicates that this unit has a TWAIN scanner driver; the software is available here: https://www.epson.eu/en_EU/support/sc/epson-l382/s/s1506
. Windows 10 has recently been modified to not work with any TWAIN driver. (Windows 11 also requires a scanner to use a WIA (Windows image acquisition) driver.) A work-around is to use the VueScan software: https://www.hamrick.com/
. The company will let you use the software for free to ensure that it works with your scanner. All scans from the free version will have a watermark added.
For other OS versions, how do you have the printer connected to the computer? If it is connected to a USB hub, try a direct connection. Try a new USB cable and a different USB port. (I inherited a scanner when a family member upgraded before checking if his USB hub was bad.) Make sure that the cable is under 6' (~2m) long. Double-check that you installed the Epson driver. Frequently, the basic driver (installed through Windows Update for example) will only work for the print feature of an all-in-one.
I hope this helps.
(I do use VueScan (free) for basic scans with that inherited scanner. It works well for my purpose since I am not scanning often.)
