How to fix Epson 410 Ink Problem

First of all, there is the seller's liability here. 
If it's from eBay, there's some protection feature for you to use. 
The "prints blank pages" problem is believed to be caused by a clogged purge tube. 

Here is a guide I found that exlpains the problem, and how to solve it: 

Recently, after changing out the blank ink tank on my finacee's Epson CX5400 multifunction inkjet printer, the printer began printing nothing but blank pages. Even after doing multiple head cleanings and test prints, pages would emerge from the printer completely blank. 
After some research, a number of fellow CX5400 owners have reported having the same problems, to the extent that the term "design flaw" became a common theme. 
I've owned several Epson printers and have had, generally, good luck with them. I was always somewhat suspicious of Epson's philosophy of making the print heads a permanent part of the printer and having the only replaceable part be the ink tanks, but it produced good-looking prints so it didn't bother me. 
Now I know, unfortunately, that this system is both a blessing and a curse. Before we delve into how to fix your blank-page-printing problem, a quick explanation on how Epson's ink delivery system works (or, rather, how it appears Epson's ink delivery system works, because Epson isn't exactly willing to divulge its trade secrets) is in order. 
There are a few components to the delivery system. 
First, you have the ink tanks. Early Epson tanks were just that; plastic boxes with a sponge inside saturated with ink. Newer tanks have a small PCB with a flash chip on it, so the printer can tell if a tank is new or used, or if it's an Epson brand cartridge or a generic replacement. In either case, the basic functionality is that it's a holder for the ink. 
Next in the chain are the ink tubes and primer. I've heard conflicting reports on how Epson printers get the ink out of the tanks; some believe that the tanks are positively pressurized when first installed, so that ink shoots out of the tank when the printer needs it. Other reports say that the printer puts negative pressure on the cartridge to draw ink out of it. 
Once the printer has the ink out of the cartridge, there are two places it can go, to either the print heads or to the purge tube. The print heads are what makes the ink spray onto the paper; the purge tube is where the ink goes when the printer primes new cartridges and cleans dirty print heads. 
Many cases of the "prints blank pages" problem occur right after installing new ink tanks. People have literally removed empty tanks from printers that work perfectly, and installed new tanks to find that the printer delivers blank pages (this happened to me). 
Since it's highly unlikely that the print heads have become clogged during the 5 minutes it takes to swap out the cartridges, the problem has to be elsewhere in the ink delivery system. 
So here's what happens when you install a new ink tank: 

1. The new tank is installed, the printer recognizes that it's a new tank, and begins the priming sequence. 
2. The printer starts to prime the tank. Ink comes out of each tank and is directed to the purge tube. 
3. The ink flows through the purge tube into the internal absorbent pad. 
4. After a couple seconds, the printer stops the priming sequence and probably does a quick print head cleaning. 

Now, a few people have done some in-depth troubleshooting and found that the "prints blank pages" problem is actually caused by a clogged purge tube. 
While this may not immediately make sense (you may be thinking, "so what if the tube is clogged, the ink will just spill inside the printer elsewhere"), here's what my research suggests happens when the problem occurs: 

1. The new tank is installed, the printer recognizes that it's a new tank, and begins the priming sequence. 
2. The printer starts to prime the tank. Ink comes out of each tank and is directed to the purge tube. 
3. The tube is blocked, so the ink has nowhere to go. 
4. After a couple seconds, the printer stops the priming sequence. 

Epson's ink delivery system appears to be a sealed system, so when the ink has nowhere to go in step 3, little ink has actually escaped the new ink tanks. This means they're not primed correctly, and won't deliver ink as they need to when the printer goes to print. 
So unless the purge tube gets cleaned out, you can swap tanks and perform head cleanings until the cows come home and it won't do any good.
Now that there's a basic understanding of what's going on, here's how to try to fix the problem. This guide is meant to be model-agnostic; I did this procedure to a Stylus CX5400 multifunction, but it should be similar for most Epson inkjets made in the past few years. 
It's unknown if new Epsons still have this problem, as it usually takes a year or more to surface. The first thing you need to do is prepare your work surface. You'll need a big table, preferably one you don't care too much about. 
If all you have is your good kitchen table, then it's a good idea to slice open a tall kitchen garbage bag to make one large sheet, and tape it to the table to protect it. Next, you'll need the following tools and supplies: (View attached picture)

How to Defusing Bomb

BOMB Defusing Manual

A bomb will explode when its countdown timer reaches 0:00 or when too many strikes have been recorded. The only way to defuse a bomb is to disarm all of its modules before its countdown timer expires.

Modules

Each bomb will include up to 11 modules that must be disarmed. Each module is discrete and can be disarmed in any order.

Instructions for disarming modules can be found in Section 1. "Needy" modules present a special case and are described in Section 2.

Strikes

When the Defuser makes a mistake the bomb will record a strike which will be displayed on the indicator above the countdown timer. Bombs with a strike indicator will explode upon the third strike. The timer will begin to count down faster after a strike has been recorded.

If no strike indicator is present above the countdown timer, the bomb will explode upon the first strike, leaving no room for error.

Gathering Information 

Some disarming instructions will require specific information about the bomb, such as the serial number. This type of information can typically be found on the top, bottom, or sides of the bomb casing. See Appendix A, B, and C for identification instructions that will be useful in disarming certain modules.

Section 1: Modules 

Modules can be identified by an LED in the top right corner. When this LED is lit green the module has been disarmed.

All modules must be disarmed to defuse the bomb.

On the Subject of Wires 

• A wire module can have 3-6 wires on it. 
• Only the one correct wire needs to be cut to disarm the module. 
• Wire ordering begins with the first on the top.

3 wires: 

If there are no red wires, cut the second wire. Otherwise, if the last wire is white, cut the last wire. Otherwise, if there is more than one blue wire, cut the last blue wire. Otherwise, cut the last wire. 

4 wires: If there is more than one red wire and the last digit of the serial number is odd, cut the last red wire. Otherwise, if the last wire is yellow and there are no red wires, cut the first wire. Otherwise, if there is exactly one blue wire, cut the first wire. Otherwise, if there is more than one yellow wire, cut the last wire. Otherwise, cut the second wire. 

5 wires: If the last wire is black and the last digit of the serial number is odd, cut the fourth wire. Otherwise, if there is exactly one red wire and there is more than one yellow wire, cut the first wire. Otherwise, if there are no black wires, cut the second wire. Otherwise, cut the first wire. 

6 wires: If there are no yellow wires and the last digit of the serial number is odd, cut the third wire. Otherwise, if there is exactly one yellow wire and there is more than one white wire, cut the fourth wire. Otherwise, if there are no red wires, cut the last wire. Otherwise, cut the fourth wire.

On the Subject of The Button 

Follow these rules in the order they are listed. Perform the first action that applies:

1. If the button is blue and the button says "Abort", hold the button and refer to "Releasing a Held Button". 

2. If there is more than 1 battery on the bomb and the button says "Detonate", press and immediately release the button. 

3. If the button is white and there is a lit indicator with label CAR, hold the button and refer to "Releasing a Held Button". 

4. If there are more than 2 batteries on the bomb and there is a lit indicator with label FRK, press and immediately release the button. 

5. If the button is yellow, hold the button and refer to "Releasing a Held Button". 

6. If the button is red and the button says "Hold", press and immediately release the button. 

7. If none of the above apply, hold the button and refer to "Releasing a Held Button".

Releasing a Held Button

 If you start holding the button down, a colored strip will light up on the right side of the module. Based on its color you must release the button at a specific point in time:

• Blue strip: release when the countdown timer has a 4 in any position. 
• White strip: release when the countdown timer has a 1 in any position. 
• Yellow strip: release when the countdown timer has a 5 in any position. 
• Any other color strip: release when the countdown timer has a 1 in any position.
