Great when they work, prone to clogging and alignment issues, picky about cartridges
on February 16, 2017
I am on my second WF-3640. The first unit worked well for a year or so, but eventually it started producing blurry output. I tried doing all the recommended print head cleaning and alignment steps, with no improvement. These Epson models have a reputation for getting clogged print heads if they are left idle for too long. This was probably the case for my original printer, as I got really busy and had no need of a printer for a month or two at a time. I checked out a couple of YouTube videos, and tried to clear the print heads, but nothing seemed to work. So, since this model is now so inexpensive and I liked the features, I thought I would try my luck with a new unit, and bought one here. After setting it up, I found that there was an alignment issue, with a bottom row of printed pixels offset, making the letters look slanted. I ran the alignment operation, but it did not help (and that is a very weird and tedious operation - it seems like a bad eye test and does not inspire confidence). Also, like some other people here, I found that this unit is picky about cartridges. I was hoping to re-use the black Epson cartridge from my previous unit, which was brand-new, but my new unit would not accept it.
