Our system eliminates this confusion by providing timely warnings for low charge, allowing you to connect your charger and ensure your power supply remains uninterrupted.

Low Resistance Connections

Solid brass connections with brass bolts, washers, and spring washers are used for extremely low resistance, reducing voltage drop, losses, and heat build-up at the terminals.

Much harder to install than expected - especially if you have a comma in your Wifi password
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
I found this printer surprisingly hard to install. First, I used the software on the DVD that came with the system. That caused my computer to crash and reboot! After it rebooted, I downloaded the (presumably newer) combo installer from the Epson web site. That ran, but when it came time to connect the printer to the wifi network, I found that there is no way in the Epson network configuration wizard to use a comma in the wifi password. There is a period and many other symbols, but I didn't see a comma. But our system admin used a comma in our wifi password, so I couldn't connect the printer to the wireless network. I had to dig up a LAN cable and plug the printer into a network switch, restart the installation and configure the printer for a LAN connection. That seemed to work, at least according to the installer, but when I tried to print a test page there was a print connection failure. After running the "Epson Printer Connection Checker", it found a printer port error and tried to fix it, but was unable to. So, I removed the printer entirely from the computer using Windows device management and had Windows try to detect the printer. That finally worked, although now the Fax device is missing. But at least now I can print, and the print quality looks good. But I'm still frustrated by the inability to connect to the wifi.

Great printer
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
This printer is compatible with my Apple Mi 4 desktop and my Apple Laptop. I didn’t have a dvd player, so I went to the required Epsom website, and downloaded the software. No issues. All of the bells and whistles on the printer works flawless. Follow the directions and enjoy the results .

Best for Business owners gets the Job done
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
This Item is outstanding. Why? I've had two HP printers all in ones however, they were okay and did the job the inks are very expensive and not worth the money quite frankly. Now this printer faxes very fast and prints very fast also holds twice the paper in its tray. I like the big readable screen display that's really an asset. The HP always a hard time with big hands to enter numbers into the printer to fax,dial, and configure. This primer comes with the CD ROM if needed. Out of the box set up was indeed a breeze. Ready to go. I was really impressed to say the least. My personal opinion is that I highly recommend this item for small business owners who like to get the job done and quickly.

Disappointed
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
The printer worked beautifully until it didn't. After 10 months use in my office (I'm retired, so use isn't heavy) it quit working. The error message advised me to remove and shake the cartridges. The cartridges cannot be removed. I'm so disappointed.

Nice functional printer at a low price-point
Style: WF-3820
At this price-point, the WF-3820 is a winner for a home printer with not much printing volume. It prints well. It was easy to set up the printer and wireless printing from a couple of computers. It uses ink cartridges. While Epson goes to great lengths to advertise/tout its cartridge-free printer models, if you don't print a lot this unit will do fine for you. Did I mention that it's relatively cheap? Has a fax function, but I don't have a landline anymore. It is a bit tall, and you have to open the scanner to access the ink cartridges; so beware if you're putting it in a cabinet or shelf without some decent head room.
