    Rated 3 out of 5 by from Okay, but notfully functional I bought this about 6 months ago to replace a HP printer in my home office. I paid the extra money to get the wide Format and Duplexer to make my life easier. I realized pretty quickly that I could not use the automatic duplexer with my Hallmark Card Studio software. Of course, I can reload the paper and print 2-sided manually, but that was not my expectations for this printer. I have tried to update the print driver, but noting has changed. I checked with the software manufacturer and nothing from them either. I am not happy with this situation. Anything else I print, I can do 2-sided automatically.

    Rated 5 out of 5 by from So far, so Great! I just got this printer yesterday. First thing this morning I set it up, and was very pleased with how easy the process was. It connected right away to my wireless router. I then installed the printer driver from the website, and was able to print flawlessly. I am extremely pleased with how fast it prints. Can't wait to try printing some photos!! This is my second Epson printer and I love how great and easy to use they are!!! I am so happy with my purchase!

    Rated 2 out of 5 by from Still in the process of Reviewing the features when used? The features for copying are Extremely Poor compared to the Epson WP-4530 I had to replace! Let me know if this can be upgraded to the quality of the WP-4530?

    Rated 1 out of 5 by from Not Happy. I bought it several months ago and I'm quite disappointed with the rate of ink use and the high cost of ink cartridges. The print quality is okay but not better than that of the 15-year-old HP printer I stopped using.

    Rated 1 out of 5 by from What an ink hog! High quality printer that is a glutton on ink! I have to keep two to three boxes of color cartridges to keep from running out. Do not buy this printer! There better and less complicated all-in-one printers on the market. I had to sent two units back before I got one that was fully functional. It is over designed, non-intuitive and requires constant attention when changing from one type and size of paper. This is my last Epson.

    Rated 2 out of 5 by from Good, When It Connects; Bad Most of the Time I have had far more trouble keeping this printer wirelessly connected than I ever did with many previous printers. This setup is almost line-of-sight with the router, maybe 35 feet or so, with no obstructions at all.
    Date published: 2021-07-01
    Rated 2 out of 5 by from Bad printing and scanning out of the box I had the preceding model that only lasted a year and a half. I bought this one a month and a half ago. It printed yellow stripes right out of the box and has gotten much worse. We've wasted a lot of time and money trying to clean printer heads, use different ink cartritdges, etc. Have only used epson ink which is too expensive. We've filed for the warranty that we paid extra for and hope it's replacement does better. It also jams literally every time I scan something.

    Rated 5 out of 5 by from Has what I need for printing music parts I need a wide-format printer for printing music parts for my jazz sextet. I use 40 lb. manilla drawing paper, 12"X18" for 2-page and 9"X12" for single page parts. For many years I used an Epson WF-7520, purchasing an extra #1 paper cassette to use with the larger size paper, and using the #2 cassette for regular 8-1/2X11 paper. This meant swapping out the #1 cassette every time I needed to print both 2-page and 1-page parts. The WF-7520 finally gave out after I heard a series of bangs inside during printing. Searching for a replacement I found the WF-7840 for the same price as the original WF-7520. It has the additional advantage of a rear paper tray, which handles the 12X18 paper much more smoothly than the paper cassette on the WF-7520 (the paper cassettes on the WF-7840 do not expand to fit paper larger than 11X17). I have owned the printer for less than a week, but it worked immediately with my Finale software and produced excellent quality parts of both paper sizes.

    Rated 2 out of 5 by from Disruptively Loud Purchased one in December 2020. Called regarding loud rubbing and squeaking noises in April 2021 and received a refurbished replacement. Now, May 2021, the rubbing and squeaking has begun again. I'm told the rubbing is normal. The volume is disruptive to the point of having difficulty carrying on a phone conversation if it's copying using the document feeder.
