Need to Know The Differences Between All Kinds of Epson Printhead

Over time, Epson print head has been the most common-used type for the wide format inkjet printer, some people may confuse with so many options. This article mainly compares several popular ones, including Epson DX5, DX7, XP600, TX800, Epson 5113, EPS 3200 head, to help you make a quick decision.

As printhead is the core of speed, accuracy, and lifespan. So please take several minutes to read and go depth with the difference among them.

Eco Solvent Printer, UV Printer, DTG Printer

Epson DX5
DX5 is the most stable, common-used and recognized printhead in the market. But the price is much too high owing to insufficient supply. Thus, it is gradually replaced by XP600 in Economy-model digital printers.

Epson XP600 (Aka: DX9/ DX11)
The speed is 10-20% faster than DX5. The lifespan can be 60-80% of DX5 with good maintenance. The price is 200USD, merely one-fifth of DX5. Ideal for start-ups. (The print accuracy which based on droplet size is comparable to DX5.)

Epson TX800(Aka: DX8/ DX10)
TX800 is an alternative to XP600, unfortunately, Epson already stopped production for this model. As a result, many second-hand TX800 are found in the market. Not recommended.

Epson DX7
DX7 It is once popular as a replacement of DX5, but failed due to higher price caused by lack of supply.

Epson EPS3200 (WF 4720)
Nearly the same as Epson 5113 printhead in appearance, specification, and performance, but gain much popularity in customers due to cheaper price and sufficient supply, and that Epson 5113 has already stopped to produce. Recommend it.

Epson 5113
It is an alternative of DX5 when utilizing water-based ink. However, EPS3200 has increasingly replaced it with rich supply and ink compatibility.

How to Solve the Problem about Print Nozzle String Ink and Clogging Ink Leakage?

In last blog, we talked about what cause DX5 printhead sometimes appear string ink, clogging and ink leakage. The problem with two aspects reasons, if you don’t know clearly, please reading last article. Now, let’s tell you how to solve the problem about print nozzle string ink and clogging ink leakage.

How to reduce chance on string ink clogging ink leakage:

1, relatively speaking, long-term jet printing better than a long time to place the maintenance of the nozzle. Keep ink in the flow state, the nozzle is not easy to jam.

2, the nozzle if you open automatic flushing state (interval of a few seconds spray all spray holes), spray holes are not easy to clog holes.

3, printing work can not last a long time. It will increase the nozzle cavity structure of the load. Especially blocking a certain number of nozzles

4, Different types of nozzles used in the ink pump model is also different. 5113 nozzles have 3200 holes, with 6.5-watt ink pump. DX5 have 1440 head spray Hole with 3-watt ink pump.

5, maintenance of the nozzle, the maintenance of the dish with a layer of sponge on the top of a layer of non-woven fabric, soaked with flushing fluid after the nozzle flat up (cleaning fluid can not be too much, can not be flooded nozzle surface).

6, nozzle installation and removal must take good. Head of the nozzle is very fragile, absolutely can not bump, do protect it. Its surface is a piece of aluminum, the inner layer coated with a crystal oscillator and a very small ink tube. Even a touch may deformed, or even broken.

I hope users can take care above points to avoid those problems. Freely let’s check and discuss with your problems. Maybe we can do some favor.

Why does DX5 Printhead Appear String ink, Clogging and Ink Leakage?

Doing sublimation printing, the DX5 print nozzle sometimes appear string ink, clogging and ink leakage. What the reasons? String ink clogging ink leakage problem will happen after a period printing service. Let’s discover the reasons from external and internal for your better experience with inkjet printer.

Why does DX5 printhead appear String ink, Clogging and ink leakage?

First, the external reasons:

1, Epson DX5 has eight ink composition by C, M, Y, K. The number of holes is 180 x 8 =1440 holes. Smallest drop is 3.5PL (1PL equivalent to 1 / 1,000,000,000 ml). If use the bad quality ink, nozzle can easily lead to the above failure.

2, The user using the syringe cleaning or automatic cleaning force is too large. Or improper cleaning methods will break the color isolation between plastic. It may cause string ink clogging ink leakage.

3, Epson nozzle integrated structure, which is different from the traditional independent nozzle. When there is a problem in a line, it will affect the whole nozzle can not be used.

4, a) the impact of automatic cleaning device on the nozzle: C, M, Y, K four kinds of wall width of only 0.6mm. The upper adhesive layer and the membrane together. The bonding strength is not high. The automatic cleaning equipment pressure is greater than the ink outside. Ink is very easy to flow from one interval to another interval compartment. Then, there will be string ink problem.

b) The effect of cleaning the nozzle with a syringe: When the operator injects the cleaning agent into the interior of the spray head with a syringe. The internal liquid of the color ink creates a positive outward pressure. The glue layer is destroyed, which also produced a string of ink. In particular, when the hole block, it is likely to crack.

Second, the internal reasons:

1, natural damage to the adhesive layer. the material itself is a polymer layer of polymer, the natural aging of the adhesive layer.

2, long-term with the ink, flushing liquid. the plastic layer between the molecular chain fracture, adhesive bonding strength becomes weak.

3, in the long-term changes in temperature. stainless steel and plastic layer as a result of thermal expansion and contraction. so that the glue adhesion reduced.

4, the role of ultrasound in a long time, or in a long period of high-frequency vibration. the adhesive surface will produce fatigue fracture, so that the adhesion decreases. In summary, the blockage is the direct cause of blockage caused by string ink clogging ink leakage. while the piezo jet force generated by the force will not make the film string clogging ink leakage.

Okay, these all above are my share about the reasons of why does DX5 printhead appeared string ink, clogging and ink leakage .

How to Distinguish New Locked DX5 Print Nozzles?

As we know, with the development of digital printing, more and more inkjet printers be used in this areas. And the printhead is a core partl in the digital printer. And DX5 printhead is popularly used in many printer. Then how to distinguish new locked DX5 printhead? Reading and following, I will share you the tips to solve this problem.

Nowadays, the Chinese manufacturing DX5 eco solvent printers were facing another round problem due to the NEW LOCKED action by Epson company.

As we know, most customers could get the Epson DX5 printhead by themselves in the market. but from this June, more and more customers reported to us that they bought the new DX7 printheads, but the new head can’t be used as normal as before. After testing the new locked printhead in our factory, we found both the printing resolution as well as the printing speed were decreased. That means the new locked DX5 printhead can’t reach the high resolution and the speed of the regular printhead. Here I would like to share with you about how to distinguish the new locked DX5 head:

1.Uninstall the 3 screws with a screwdriver, like the photo below:

2. You can get a circuit board photo of the printhead, like the photo below:

As we can see from the upper and right corner, there is a serial No. for example, the above head serial No. is “12350201”, 12 represents the Year= 2012; 3 represents month= Mar. This head is the old locked head.

But if you see “188…..” this head is definitely NEW LOCKED Head. Because the heads which were produced from Aug, 8th,2018 are all NEW LOCKED VERSION.

Finally, we suggest you to purchase the printhead from your original machine supplier to avoid the problem.

Okay, these all above are my share about the method of identifing wether DX5 print nozzle is new locked. If you have any other needs or questions welcome to contact us at any time. We will provide you the best quality product and service. Hope my article can be useful to you. Thank you for your reading.
