If you can find it :-(. Epson doesn't repair these for the general public when they break; they swap them out or invalidate the support on the broken one and transfer the warranty to the replacement printer; I suspect the transport issues bulk tanks create is one where Epson just says to "recycle it locally" (which where I am for example, very well could mean you're "recycling" it with Tannerite and sacrificing your grass with a permanent ink spot unless you suck the ink out OR in other areas, actually recycled). That said, this doesn't mean you can't find the part. I would find one with a big fault that's not economically repairable with known good wireless (or at least likely known good). It will look something like this.

I suspect finding the part will be hard because, to a degree, few people properly recycle them when they die because they are a pain to transport due to the bulk ink tank, so there are not as many parts to go around stripped from these things. With printers, you often have better luck stripping it off a donor, even lasers (for example, I've had to retire units with major problems I can't fix or it's cost me too much to continue the attempt, but if I have the space for it and I like the series I'll keep the old printer for parts within reason). Look for one with a nasty fault code, such as the ink/paper light cycling combination or E-11 (waste ink pad error on non-serviceable Epsons), or a fault in an area like the platen, even one with a serviceable pad, but the platen pads internally are soaked, and these remain non-serviceable. As a bonus, see if you can suck the ink out that remains, especially if it's OEM Epson ink. These are usually death sentence defects because the platen is a big job (and you will also need to adjust the printer to the new head with the Epson SW unless you carry over your current printhead and can verify it's easily corrected to the new platen). When it comes to waste ink pad repair, it is easy if you can replace the pad, but you need the Epson tools or WIC reset tool. The issue with the waste ink reset is it needs to be supported for a successful reset. Cleaning it is messy and often not worth the mess, as you rarely get it back to 100% absorbing capacity, and there will always be some leftover ink that never cleans up.

I don't have a SM for this one. They usually come apart by undoing two screws from under the control panel and the whole top is loose, but you need a prop rod due to them not being built with it internally.
