This company has terrible customer service and serious flaws in their printer design
Style: WF-4830, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
I have never posted a seriously negative review of a product in the past as I try to work with the manufacture to fix their product problems and keep the customer happy. However, after prolonged attempts at resolution with this products issue I have to post something to show my frustration. The company has horrible customer service and does not support its flawed product, so I need to warn other potential customers to avoid my expensive mistake and seek a different manufacturer to purchase your printer and your ink. I bought this printer in December of 2021. It initially worked fine. I left on a vacation in July and returned in August to a long list of items to complete with close deadlines. Many required me to use my printer. Unfortunately, when I turned on my computer, I chose to update the software for the computer and for the printer (automatic requests that I clicked yes on – bad mistake). Once the printer software was updated it rejected the ink in my printer (which has worked previously and was Espon brand). Given very tight deadlines I called all over town and found some new Epson ink 20 miles away. I bought it and returned. The printer rejected the new yellow ink. I called customer service asking for help rolling back my printer software so I could finish my job and was dismissed. Now with a few hours deadline, I had to go buy a NEW printer and new ink (clearly NOT Epson brand), return, install and print. The deadline met, I recontacted Epson and asked them to take my printer back or replace the software as it was useless. I could not even print with black only ink when it rejected the yellow cartridge. They simply ignored me but asked for receipts, etc. to prove I bought new Epson Ink. That required more of my time to scan (with my new printer mind you), fill out forms, and submit. Weeks later they sent me a single new yellow ink cartridge. By then I was traveling again. I returned a month later, the ink was in my mail. I installed it – It does not work so now 6 weeks after the original problem I still cannot use my printer. I suspect to get any help I will need to go through all the same paperwork and hassle and will have no resolution of the software issue, which is the real problem, not the ink. Bottom line – this is a deeply flawed device with very touchy software glitches. The company is so paranoid to protect their ink business that they had made their device(s) unusable. I now see they were sued and they settled that lawsuit a few years ago. What they have not done is fix the problem nor do they want to help customers who have problems. I strongly recommend you not buy this device and seek a different manufacturer (probably none of their devices after reading the lawsuit information and noting they have not agreed to resolve the problem).

First Rate Office Printer.
Style: WF-4830, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
This is the second Epson product that we have owned. The previous model was still working after 8 years of dependable service when we replaced it. We tried to move up to an Eco Tank model that we purchased locally. The unit would not connect to our wireless network, so we returned it to the store and purchased this model from Amazon. The overall quality of the output is just as good or even a little better than our old model. This unit is quite a bit faster that our old unit. The unit was also reduced by 34%, making an excellent buy. The jury is still out if it will be good in the ink usage department. Our old unit seemed to need a new cartridge every other week, I would purchased this model again,
