How To Clean The Black On A Wp-4530

Introduction

Note: Epson doesn't recommend or endorse the procedure described in this tutorial.
It's unbelievable how Epson print heads get clogged. No matter how good they are, they become clogged for no reason and don't unclog past themselves. Either you change the head or manage to unclog it by using a liquid made past Epson, which costs a small fortune – when y'all become to find it. So the poor technician has almost no adventure to repair such printer.

First, allow's study how the system works. There is a tube (called "needle") that makes a hole in the cartridge plastic and, by doing and so, creates a pressure seal that helps prevent ink leakage and to create a kind of vacuum in the cartridge. If this vacuum didn't exist, the ink would certainly flow completely though the head holes. That'south why when someone removes the cartridge (original or not) from an Epson printer, they encompass the nozzle with a tape: the tape keeps the ink from flowing. When the cartridge is reintroduced in the printer, the tube makes a hole in the record and creates the same pressure seal.
As you can see in Figure 1, the ink enters through that tube and goes to the head nozzle plate, passing by an ink filter and temporarily stored on the cavity, which is a small ink tank.

The expulsion area works with piezoelectric elements (a.yard.a. PZT, Piezo Electric Chemical element) that, when "energized", move and expel ink aerosol that fall to the newspaper. The ink course is non a direct line, equally yous can run into in Figure 2. Because of that, information technology works every bit an one-way valve – yous can drop ink up to downwardly, but not the other mode around.

The problem happens with the ink (original or not) deposit in the nozzle plate. The ink gets solid and clogs the hole. No matter how you try, the ink doesn't come up out. And it'due south not expert to throw a print head away…
