How to Fix an All-in-One Printer, Manage Virtual RAM, and Upgrade a Computer

Q: I have an Epson XP-830 all-in-one printer. It’s connected to my wireless home network and prints from my desktop and laptop using Wi-Fi. But I can’t get the printer’s scan function to work. When I try to scan to my computer, I get the message: “Communication problem. Check if the computer is connected. When I tried to reinstall the Epson software, I get to the end and it says: “The printer was not found. Make sure the printer is connected to the same network as your computer. I checked my Norton Security settings and checked Epson features to allow them.

The print function works well. Can you help me get the scan function working again? It worked before, but I haven’t used it for a while. I now have Windows 11 on my desktop, if that matters. I’m confused.

A: The first step is to make sure you have the latest drivers and utilities for this printer, especially since you upgraded to Windows 11.

Also, you may need to run the scanner application as an administrator. Since unlike a printer, a scanner sends data to your computer, Windows 11 may block communication if you don’t run the program as an administrator. Right-click on the program and see if there is a “Run as administrator” option.

If none of these steps work, it’s time to contact Epson technical support.

Q: I just read your column from January 29 and would like to comment on the main reason why I installed SSDs in my computers. Over time, software applications in general have become more demanding on RAM memory usage. When demand exceeds what is available for a given task, computers start using “virtual memory,” which is actually hard disk memory and is much slower than solid-state RAM. This phenomenon has slowed down many of my computers. Replacing the SATA drive with an SSD has breathed new life into my old computers by dramatically speeding up virtual memory retrievals. I use Acronis software to clone my SATA to a new SSD and the computer boots and works perfectly after that.

—Greg Kromholtz

A: Makes sense. Solid-state drives (SSDs) are nearly indestructible and faster than SATA drives.

Yet unlike SATA drives, SSDs have limits on the number of times they can be written. The good news is that there is a high ceiling on the number of writes. According to one estimate I’ve seen, if you wrote 100 GB of data per day to an SSD, it would take you 27.4 years to hit the limit.

But keep in mind that if you don’t add RAM to your computer and the operating system uses your SSD as virtual memory, you might hit that cap much sooner.

With that in mind, why not add RAM to your computer so it doesn’t have to use virtual memory?

Q: Do you have any idea what it is? I recently upgraded to Windows 11 which was a big mistake. Now I’m getting slow replies and can’t find anything.

And I get the following error message: “ This XML file does not appear to have any style information associated with it. The document tree is shown below.

A: Whenever one upgrades to a new version of an operating system, it is advisable to ensure that you have the latest version of the programs and drivers that you have installed. And yes, some developers may be a bit late in updating which may lead to bugs.

Since it looks like you’re getting this error message when using a web browser, my recommendation is, first, to update that browser, and second, if the problem persists, use another browser until the one you are using is updated.
