Each built-in cleaning cycle will remove some ink out of the cartridge and then dump the ink on a waste pad. 2) a built-in cleaning function which uses an external waste pad to suck and wipe the printhead. On the contrary, Epson relies on two things: 1) an internal one-way damper that makes ink flow one-way only. For example, an HP printer pumps air into an internal bladder, which squeezes ink out of the cartridge, and therefore flushes the air bubbles (or dirt) out of the printhead. To deal with the air bubbles, many HP and Canon printers have built-in pumps. This is why printers tend to clog right after a cartridge change. When we change the cartridge, we may push some air into these intakes and create bubbles. There are small cone-shaped ink tubes (ink intake) on top of the printhead. We will take a closer look at where the cartridge feeds ink. Consequently, we will remove the air bubbles from the damper.Īnother place that air bubbles can form is inside the printhead. We recommend using a syringe to suck air from the cartridge ink outlet after each refill. Once we refill the cartridge, the air in the damper can clog the printer.

By this time, the ink is depleted, and the damper is full of air. However, most people use the cartridge until they see that a color runs out. For a new Epson cartridge, the damper should be full of ink and thus less likely to have bubbles. The damper forces ink to flow one way only: from the cartridge to the damper and then from the damper to the outside. Epson cartridge has a built-in damper (Picture). Let’s explain why Epson’s cartridges seem less likely to clog than a refilled Epson cartridge. It can also occur due to no reason at all. The bubble can form when you are switching to a new ink, changing a cartridge, or experiencing room temperature fluctuation. There are three kinds of clogging:ġ) Clogging caused by debris, fibers, and other foreign objects To understand why Epson’s printer is so easy to clog and why sometimes a new cartridge will solve the problem, we need to understand the mechanisms behind clogging. If a new Epson cartridge didn't fix the problem, the person would conclude that the refilling process broke the printer. If the new Epson cartridge fixes the problem, the person would conclude that he or she should stay with Epson. As an attempt to solve the problem, a person may switch back to an Epson cartridge. Most people will blame the poor print on third party cartridges, ink quality, ink type switching, and so on. For the owners of Epson printers, there may be a day that we find the printer prints in stripes. However, the permanent printhead becomes a major problem when it is clogged. A permanent printhead has better quality and durability than a one-time-use printhead.
Most Epson printers have a permanent printhead.
