What’s The Pros & Cons of Epson, Toshiba and Ricoh Print Head?

At present, the most common UV printer nozzles in the industry are Epson, Toshiba and Ricoh. The life, accuracy and stability of the nozzle directly affect the use of subsequent equipment. The core is to look at the price of the nozzle, the cheap nozzle is not expensive, in fact, this is a lot of customers are not particularly aware of the nozzle, and now for everyone to spread some small common sense about the UV printer nozzle.

UV flatbed printer

From the perspective of print fineness, Epson’s nozzle is the finest, followed by Toshiba and Ricoh again. The color printed by the Epson nozzle is more saturated, because it has a finer orifice and a smaller ink point, which improves the overall printing effect. Toshiba nozzles are second only to Epson, Ricoh’s nozzles are larger, and the three machines will be more obvious at the same time.

We know that the print speed is determined by the fineness of the printhead, the quality of the print, and the size of the print. The same print material, print pattern, print format to compare, Epson’s print speed is the slowest, followed by Ricoh, and finally Toshiba. Toshiba prints are twice as fast as Epson.

1, printing accuracy: Epson dx5 nozzle (ink point 3.5pl)> Toshiba CE4 nozzle (ink point 5pl)> Ricoh G5 nozzle (ink point 7pl)
2, nozzle life: Toshiba CE4 nozzle (36-60 months)> Ricoh G5 nozzle (9-18 months)> Epson five generation nozzle (2-6 months).

4, nozzle stability: Toshiba CE4 nozzle > Ricoh G5 nozzle > Epson five generation nozzle. 5, printing speed: Toshiba CE4 nozzle > Ricoh G5 nozzle > Epson five generation nozzle.

Customers can decide according to their own comprehensive needs. Epson is a civilian nozzle, Toshiba and Ricoh are industrial nozzles. Toshiba nozzles are currently the most cost-effective in the industry, and they are the most widely selected, which greatly reduces the maintenance costs in the later period.

The difference between Epson secondary encryption and one encrypted print head

Recently, a wide-format printer that is produced and assembled using an EPSON secondary encryption print head has appeared on the market. So what is the difference between secondary encryption and one-time encryption? Here we make a simple analysis.

print headShortly after the launch of the EPSON one-time encryption printer printhead, it was quickly cracked by the manufacturer of wide-format inkjet photo printers. The reason is that the encryption algorithm is simple, and with a little analysis, it can be perfectly cracked. The encrypted one-time encrypted print head and the unencrypted print head have no difference in speed, ink output and life, and can be used normally.

After an encrypted printhead was cracked, EPSON carefully summarized and learned the lesson, and then started the secondary encryption of the printhead. For this encryption, EPSON has adopted a more rigorous algorithm.

A variety of printheads, including the Epson DX5, DX7 and 5113 printheads, have been added to the secondary code. In view of the more rigorous encryption algorithm, in the strict sense, it is impossible to achieve a real crack for the secondary encryption Epson print head.

So why are there still wide-format photo printers that use secondary encryption printheads on the market? The situation is this:

print headDomestic wide-format photo printer manufacturers have adopted a compromise method in order to use secondary encryption print heads. One-half of the eight rows of nozzles of the printhead, that is, four rows of orifices, and the other four rows of orifices compensate for the defects produced by the first four rows of orifices. Simply put, only eight columns of eight rows of nozzles are working really, and the other four columns are doing nothing.

The use of a print head in this way results in a reduction in print speed and ink throughput by half, which is only one-half of the normal case.

In order to make up for the above defects, the manufacturer has adopted an extreme practice of increasing the driving voltage and the ignition frequency, thereby increasing the workload of the print head. As a result, there is a possibility that the life of the print head is severely shortened. According to estimates, in the current environment, the secondary encryption printhead has a life of only a quarter of the original printhead.

Recently, some users complained that his secondary encrypted printing head was broken in 2 or 3 months, which is why.

In view of this situation, when reminding customers to purchase a wide-format photo printer, be sure to have a clear understanding of the print head situation.

90% of people don’t know how to clean the print head of uv flatbed printer

The core component of the UV flatbed printer is the print head. Regarding the correct and effective UV printer nozzle cleaning, many customers and friends are not very clear or the method is not appropriate. Below I will analyze the correct method of UV printer print head cleaning, hoping to help customers and friends!

Uv flatbed printer 7 points by maintenance, 3 points by quality.

Cleaning the uv flatbed printer printhead is an important technical activity in the maintenance of the uv flatbed printer. Correctly mastering the cleaning method of the sprinkler can well maintain the printer nozzle, effectively extend the service life of the sprinkler, and reduce the depreciation cost of the device. So how do you clean the printer nozzle, what should you pay attention to during the cleaning process?

Preparation: The rear of the printhead nozzle of the uv flatbed printer also includes the nozzle drive circuit board, so it is necessary to protect the drive circuit board and wrap the rear half of the warehouse with the usual plastic wrap.

print head

There are several ways to clean the print heads of a printer print head:

The first method: immersion method

Scope of application: lighter resistance

Essential tools: 95% alcohol, a clean cup and a flat metal container.

Prepare a small flat plate, place the spray head flat on the plate, and then inject the special cleaning solution for the uv printer into the plate, the depth of which is just immersed in the nozzle. Be careful not to spill water on the cable plug and drive board. The first soak time is about 1 to 4 hours.

The second method: print head injection flushing

Scope of application: The situation is blocked.

Essential tools: 95% alcohol, a clean cup, a disposable syringe, disposable infusion set.

Working principle: Using the pressure generated by the siphon action of the syringe, the organic solvent of alcohol is injected into the print head to clean the dry ink head.

Use a plastic tube of a disposable infusion set, insert one end into the 5ml syringe, insert the other end into the ink inlet of the nozzle that needs to be flushed, and press the distilled water in the syringe into the nozzle, paying attention to the pressure is not too large, so as not to squeeze the water. Waterproof isolating glue inside the bad nozzle. This process needs to be repeated several times until it is seen that each of the ink outlets ejects a fine water column. In this way, the blocked nozzle is completely cleaned.

The third method: distilled water cleaning

Scope of application: severely blocked

Essential tools: a decoded empty cartridge, a disposable syringe, and a bottle of medical distilled water (also available in clean water).

Working principle: It is similar to the working principle of pressure cleaning method, and will not be described here.

Solution: Prepare a decoded empty ink cartridge, a disposable syringe and a bottle of medical distilled water. Using the pressure generated by the siphon action of the syringe, inject the syringe into the distilled water through the vent hole of the ink cartridge, and then inject it into the cartridge for a while. The injected distilled water is sucked out by a syringe, so that the remaining ink in the ink cartridge is washed repeatedly several times.

The fourth method: ultrasonic instrument cleaning

Scope of application: the most severely blocked

Working principle: The ultrasonic cleaning machine generates strong ultrasonic waves to make the water molecules vibrate violently, and the fine dry ink particles are shattered and dissolved in water to achieve the purpose of cleaning.

Solution: Put the inkjet print head gently into the washing machine, add pure water or special print head cleaning solution, pure water or special print head cleaning solution is just enough to cover the stainless steel edge of the print head (be careful not to let the pcb board Contact with pure water or special cleaning solution), and clean it quickly after 10 to 15 hours. The advantage is that the cleaning effect is very good, the print head that has been blocked for many years can be cleaned and the operation is very simple; the disadvantage is that the maintenance cost is high and the price is relatively expensive. Under normal circumstances, ultrasonic cleaning machines can be found in hospitals, eyewear stores or mobile phone special maintenance points, and some places are free, and can also be modified with ultrasonic humidifiers. It is worth noting that the cleaning solution must use pure water or special print head cleaning solution. It is not allowed to use the cleaning solution of the hospital, eyeglass store or mobile phone special maintenance point, because the cleaning solution of the glasses store generally contains more impurities, the hospital The cleaning solution of the mobile phone special maintenance point is generally a strong organic solvent, and frequent use can cause fatal damage that is difficult to repair the inkjet print head.

The fifth method: If the operation has not cleaned the print head, it is basically a hard blockage. At this time, it is recommended to contact the manufacturer and use the manufacturer’s equipment for cleaning.

Epson flat series printer nozzle cleaning method:

1. After the equipment is installed, and the maintenance of the printer head is carried out at the beginning of the equipment startup

1). In order to make the nozzle enter the best working condition, please use the 1-2 days to print some pictures as much as possible before the equipment officially begins to undertake the production business. The picture is best used in CMYK 4 colors, and in the picture. Both sides of the C, M, Y, and K color bars are added to ensure that the four nozzles are always in the inkjet state, just like the car just bought back, the better the wear-in, the smoother the machine will be used later. .

2). It is best to take out the moisturizing sponge in the rightmost cleaning station together with its bracket when printing.

2. How to maintain the printer head after the daily work is completed

After all the print jobs are completed every day, in order to keep the nozzles in optimal working condition and to avoid clogging the nozzles due to solvent evaporation, please use the following methods to maintain the equipment for the night.

10. Turn off the power to the device.

2). Clean the moisturizing sponge with a special cleaning solution, then pour the cleaning solution onto the sponge to soak it.

3). Move the handpiece back to the rightmost cleaning station and tightly bond the nozzle to the moisturizing sponge.

4). Keep this state for the device to stay overnight.

3. The treatment method after finding that the nozzle is slightly blocked

1). Recommendation: After the printer head is found to have a slight clogging phenomenon, press the PAUSE button to pause the printing operation without any hesitation. Then use a vacuum cleaner or a manual air pump to spray the ink from the printhead to clean the printhead. After cleaning, it must be squeezed with plastic. The pressure bottle sprays some cleaning liquid onto the nozzle surface to wash away the residual ink.

Note: Do not use excessive force when using the manual air pump, otherwise the print head will be damaged due to excessive pressure.

2. Timely and decisively and thoroughly handling the slight clogging of the nozzle is very important to keep the nozzle in optimal working condition during long printing!

3. In addition, it is also necessary to carefully check the condition of the nozzle and find out why the printing head is clogged.

4. Treatment method when nozzle clogging frequently occurs during the printing process

1. Press the PAUSE button to pause the inkjet job, then press the PURGE button to move the nose to the leftmost cleaning position.

2. Keep the power of the device on, and unplug the liquid level sensor signal line that connects the sub-tank to the head control board.

3. Unplug the ink supply tube (from the secondary ink tank) on the nozzle, and then use a glass syringe to extract the special cleaning solution to clean the nozzle. Method: Use 40ml of cleaning solution every 10 minutes, every 3 to 4 times. .

4. Re-insert the ink supply tube and level sensor signal line after cleaning, and then continue the previously paused print job.

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.

epson print head

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.

7 common sense about the print head of UV flatbed printer

The print head of the UV printer is believed to be one of the most concerned issues for all users, and it is also a question that is repeated and repeated. After all, the print head is the most frequently used in daily use, and the most common problem occurs around the print head. Understanding the common sense of the print head can help us become more comprehensive and professional.

print head

Import and domestic

The domestic uv printer print head, whether it is Epson print head, Seiko print head, or Konica print head, Ricoh print head and other print heads, are imported, and 90% of them are imported into Japan, and the rest are from the United Kingdom and the United States. Since the country does not have the corresponding technology for the time being, it cannot be produced.

Civil and industrial

print headThe print head of the UV printer itself is not divided into civilian and industrial, but there are big differences in the printing results, printing speed, printing performance and other parameters of different print heads. In order to facilitate the user’s understanding, the industry will divide the high-performance, long-life, and compatible print heads into the industrial field. In contrast, short printheads, high failure rates, and inexpensive printheads are classified as civilian printheads.

Cheap and expensive

To believe that “a penny and a share of goods” is the eternal truth, any product sold by a business is to make money, it is impossible not to make money, or even to sell at a loss. In the same way, there are no good, cheap nozzles, only good and expensive nozzles. Don’t be deceived by the slogan of advertising, you must make a rational judgment.

Print head and technology

Under normal circumstances, the more expensive a printhead is, the higher the capital, manpower, and material resources of the corresponding motherboard program development and upgrade services. Therefore, this has become an important criterion for judging the technical level of the manufacturer. The technical gap between the manufacturers can be compared by asking the price of the nozzles made by the manufacturer.

Print head and ink

Different uv printer nozzles have different nozzle diameters, nozzle materials, and internal structures, so it is important to remember that inks cannot be mixed. Otherwise, it will not only cause a reaction between the inks, but also shorten the life of the printer head, causing it to be clogged.

Encrypted and not encrypted

print headEncrypted and unencrypted printheads primarily refer to the Epson DX7 printhead, which has an encrypted printhead, a secondary encrypted printhead, three encrypted printheads, and an unencrypted printhead. Encryption means that the printhead will print a certain distance after printing, and a color bar will appear, causing the pattern to be scrapped. Unencrypted printheads don’t have this problem, but the price is more expensive than encryption. Domestic uv printer manufacturers are more mature in the process of decoding one encryption and secondary encryption, but the three-encrypted print head is still being cracked.

Warranty and no warranty

This is the last one, mainly because the users who ask too many questions ask and care about it. Once the printing head has been shipped from the factory, it will be returned for sale and replacement unless it is problematic before it is used. Installed on the equipment, after the ink is tested, the problem is that it is not guaranteed. There are too many main uncontrollable factors.

From this point of view, in fact, the printer print head is not without warranty, it is part of the consumables. Why do you often hear that some manufacturers advertise printheads for 1 year or even 2 years? These are just slogans for propaganda. Carefully review the terms of the warranty, various additional conditions, additional costs, harsh to say not to report for 1 year, 20 years of insurance are manufacturers to make money.
