    Glitchy Right Out of the Box. Wastes Materials.

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    Read a lot of negative reviews after I purchased this printer. I'm philosophical about those things normally, so I was undeterred. However, within the first usage there were problems. I've been a graphic designer for 28 years, so I'm not new to printers and how they work. EXAMPLE: I had an InDesign file (black & white only) with a master page set up with vertical copy with the top facing left. A master page sets up ALL PAGES in the file the same way. I sent pages 1-20 to print. First 10 pages were fine. P11 had the copy flipped with the top facing right. P12 and 13 were correct, then P14 & P15 were fllipped, P16 - 19 were correct, P17 flipped. I sent one set of print instructions for one print job containing all 20 pages and didn't touch it. The printer arbitrarily and randomly flipped pages the wrong direction. ANOTHER EXAMPLE: Sent another multiple page print job from a different file (CMYK). First 6 pages were perfect. 7th page had altered colors - muddy, dark and nothing resembling the correct colors or the colors printed in the first 6 pages. No settings were changed mid-print, not by me at least. Did a nozzle cleaning with no change, still dark and muddy. I had to build a completely new file from scratch. I was printing several files that needed to be assembled after printing and they needed to match. Some of the other files printed fine and some did the color change thing MID-PRINTJOB. Cleaning the nozzles did not fix it. Never, in 28 years have I had so many random, strange printer related problems at one time. Since each of these problems happened within a single print job where part printed perfectly and part was totally wrong, it is conclusively a printer issue. The only way I was able to successfully finish my projects was to print ONE PAGE AT A TIME. With several multipage pieces to be printed where quality was paramount, this became a ridiculously long process. Cost me $100's in expensive, special ordered paper. This printer is brand new. I used to buy Epson printers exclusively, but this is the last Epson I will ever own. It's very heavy for me to manage on my own, but I will return it and buy another brand. Do yourself a favor. Read and believe the reviews. This printer is a lemon. There are many, many people out there who agree with me. I guess that's why it was marked down over $100 when I bought. Epson is obviously trying to clear them out. NOTE: this review is no reflection on Best Buy. They're good folks. I have no complaint with Best Buy, only Epson.

    Epson and Best Buy both insufficient

    • Verified PurchaserVerified Purchase

    I bought the Epson WF-3640 at Best Buy. It printed OK, copied OK, and scanned OK. The Epson diagnostics said the fax was connected and ready, but after a couple of weeks without even a junk fax, I discovered that the unit was unable to make a call or receive a fax. Although I have analog phone lines, Epson tech's diagnosis was that I needed to install a DSL filter. This was 17 days after purchase. I figured the unit had a bad fax module. and since I was within 30 days of purchase, I took the unit to Best Buy to exchange. My attention was directed to the small print on the receipt, about a 15-day return period. It made no difference that I did not want a refund, but was exchanging a non-functioning item. So, back to Epson tech. After repeating the meaningless round of diagnostics, the tech agreed to exchange. I give Epson 5 stars for its exchange system. FedEx brought the replacement unit in 2 days. I set up the new 3640. Prints OK, copies OK, does NOT scan, and does NOT fax. Called tech, who transferred me up a level to someone spoke American-accented English. Repeated the same diagnostics. Tech concluded I need a "fax filter", that is, a DSL filter, because otherwise the 3640 fax would work. He refused to believe I have analog. He insisted I call AT&T so he could talk to them. He then agreed to call me back in 5 minutes, during which I should confirm with AT&T. He refused to discuss the scan problem until I called AT&T. He then informed me that Epson's warranty does NOT allow refunds! He said Epson would exchange again, but the new unit will not fax on my DSL. So, we disconnected. I confirmed with AT&T that I have analog, and waited for the tech to call back. It is now 25 hours later; right, NO call back. Current status: No scan, no fax, no faith in Epson, and ill will toward Best Buy. It is looking like I will go to and buy a HP 4 in 1...and test the fax immediately. I will find a charity that needs a 2 in 1.

    Excellent Printer!

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    I've been a longtime HP printer guy (for approximately two decades) and I'm just not impressed with the printers anymore. I last bought the HP Photosmart Premium Fax e-All-in-One Printer - C410a about 3 1/2 years ago at Costco. My wife and I are both in college and our two kids (one in high school, the other in middle school) use the printer a lot for various writing projects, etc., and it seems like we are burning thru ink cartridges at a high rate. I've witnessed firsthand the steady price increase, which we also buy at Costco, of replacement ink. This is what prompted me to try something new, something other than an HP printer. After doing an extensive search online, I discovered the Epson Workforce WF-3640. Being an HP printer guy for so long, I was still hesitant at first, but decided it was time for a change. My wife and I (and the kids too) simply love this printer. I like the design and look of the printer, I love having two paper trays (for a total of 500 pages), and I love having actual buttons on the printer when they're needed. I'm so glad we made this purchase! I would recommend this printer to everyone I know! *And one last thing - replacement ink cartridges are about half the cost of the previous HP printer ink cartridges. Yes, we'll be buying the EPSON ink cartridges at Costco too, but we'll be paying half the cost!

    Great for small, at-home businesses!

    • My Best Buy® MemberMember

    I needed an all-in-one that was reliable (great reviews from reliable reporting agencies), relatively fast, worked with Air-print for my iPad, and was not an 'ink hog' and this model kept coming up consistently. Although it's got a larger foot print than some others in it's class, the very functional and easy to navigate led display is worth the additional 'real estate'! I've only had it a few weeks, but, so far, it has performed flawlessly. Setup, for me, was easy and fast, and I am not the most tech-proficient person. I read through all of the instructions first, and then, followed them, step by step. I would definitely recommend purchasing at a Best Buy store, if you are close enough to one. Since they price match, you'll get the best price, and it is easier and faster to deal with any problems that might occur (most of the few negative reviews that I read had to do with jostled parts that occurred during 3rd party shipping - but many others had no issues with ordering online). I have been extremely satisfied with Best Buy's customer service (and floor staff) the very few times, in the past, that I needed to adjust a purchase in some way. So far, I have not needed to do that regarding this printer. If you don't mind the slightly larger size of this unit (compared to other - less functional - home units) and require a solid printer that is affordable - especially if you are running a small business from home and don't need a machine made for heavy, commercial-type output - this is a terrific choice! The printing is excellent, and the graphics are more than adequate for a home-based enterprise. The double paper trays are very convenient and I will probably never use all of the features that this machine provides. At this price point it is a great value.Very happy with this purchase!!

    Great for all types of paper - uses a lot of ink

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    This is one printer that I always seem to come back to. It's a great printer for the following reasons: 1.) Uses Epson ink, so the ink doesn't smear or smudge with water. 2.) You can buy XL cartridges so the ink goes further, and the XL cartridges usually run about $10 more than the normal. 3.) The rear feed allows all types of papers, including 110 lb cardstock, which not many other printers allow. 4.) The manual feed scan function is great so you don't have to handfeed each piece of paper. 5.) It prints double-sided on its own, meaning you don't have to flip the paper manually. Some downsides: 1.) Uses A LOT of ink. If you are going to be printing A TON, I totally recommend the Epson ET-4550. But NOT if you are going to print on anything weighing more than 20 lb (a normal sheet of paper.) The ET-4550 is HORRIBLE with paper of any other weight. 2.) After a while, it does have problems gripping the paper and you have to clean the rollers frequently. 3.) The quality degrades after a couple of thousand of pages. I always seem to get these lines on the bottom of the paper that I can't get rid of no matter how hard I try. 4.) This printer will typically last me for only 2 years before I notice the quality decreases beyond repair. HIGHLY recommend getting the Best Buy warranty with this printer. Overall, if you are the type of person who prints on all types of media, this is one of the best printers out there. If you do bulk printing, or professional printing in large quantities, you may want to skip this printer and look for something with better efficiency.

    Your joy will turn sour soon enough


    I bought this product when it was on sale. $99 down from $180. I needed a new printer to replace my old one so I figured this was as good as any. I was right at first. It was a major upgrade from my old machine. But that was when the cons started popping up everywhere. First, the ink cartridges. They are small, no bigger than a dozen credit cards stacked on top of each other. They use ink quickly and if you print a handful of color documents a day, you'll be out of ink in a few weeks. Second, the ink usage. More specifically, even if you choose to print in black and white, you will notice over time the ink levels in your other cartridges going down. Even in black and white, the machine actually uses your color ink, which I find absurd. Which brings me to my biggest criticism of all: black and white printing. Let's say you use up the last of the ink in your cyan cartridge. No big deal, you just decide to print in black and white. You can't. The printer won't do it. Even if you want to print a document in black and white, if one or more of your colored ink cartridges are out of ink, you cannot print in black and white. That was a tipping point for me. They lowered the ability of their machines in order to sell more ink cartridges. That is where I draw the line. There are other flaws (slow printing compared to other printers, low paper tray capacity, if your printer is on and you're missing a cartridge it will beep very loudly and warn you every 5 minutes) but that was the big one for me. Not only do I not recommend this Epson product, I do not recommend any of them.

    Best printer I've ever owned

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I used to be an HP-only person, mainly because of their reputation and their cost-per-page printing capabilities. Well, after my latest HP stopped working (and they've all broke), I decided to do some research before buying a new multi-function unit. All that research lead me to this Epson. Even though their prints per cartridge don't match up to HP's, this Epson printer uses less ink for maintenance (if you don't print at least once a week, the printer has to clean itself and to do so requires ink, this Epson is very efficient in that regard - according to the research I found online). Another issue I've always had with my HP's is that the wireless connection was always spotty. This Epson was literally connected to my laptop in 30 seconds. I connected it to my iPad just as quick with no issues (after simply downloading an app). I haven't been able to get my Andriod phone to print, but I only tried once, couldn't get it to work and have been meaning to look at it further ever since. I don't have a big need to print from my phone, so I haven't spent any time trying to figure it out. I can also scan a document and have it show up on my computer (or any device you select) wirelessly. The print quality is great and with 2 250-page trays, it's holds plenty of paper. In summary, this is the best multi-function printer I have ever used. It was so simple to set up, the print quality is excellent, it print quickly and is fairly efficient when it comes to ink. I would highly recommend this to anyone looking for a new printer.

    I replaced my HP with the Epson WF 3640 several weeks ago and began regretting it almost immediately. At first, I thought it was just a matter of getting used to a different user interface. Then I realized that the control panel was unnecessarily complicated. Among other things, you need to go through multiple steps just to replace ink cartridges -- which you'll be doing quite a bit of since they don't last any time at all. And good luck finding them since the major office supply stores can't manage to keep enough in stock (perhaps because the ink runs out so quickly). When I finally bought a replacement cartridge online, it lasted through about 10 pages before running out (the supplier assumed it was defective and replaced it). The "second" paper tray doesn't work. And now that I have spent $70 on 2 of the 3 additional cartridges that are low, the printer has taken itself offline and is not working. At this point I am seriously considering just trashing it and writing off the $140 as money wasted on a failed experiment, It is the absolute worst piece of electronic equipment I have ever owned.
