What should I pay attention to when buying a handheld inkjet printer?

Many customers want to buy the cheapest inkjet printer. This kind of psychology is understandable as a consumer, but it is very cheap to buy, especially the handheld inkjet printer that is significantly lower than the market average price. There are many risks and problems. This It also requires us to predict and think in advance! Today, engineers from Shanghai Qianli will share with you what you need to pay attention to when buying a handheld inkjet printer. 1. Pay attention to the printing distance required by the product. Hand-held inkjet printers have entered the Chinese domestic market for many years, and a large part of the reason why they have not developed is due to the limitations of their use of marking products. Many customers think that the new type of handheld device is technologically advanced and widely used. This view is very one-sided. Hand-held inkjet printers have actually been in existence for many years. The biggest reason why they have not been developed and promoted is that they have very obvious limitations in use. The working principle is very similar to that of high-resolution inkjet printers. It needs to be very close to the product. The only difference is that the structure is different. From the computer program connection control to the handheld touch screen control, the print heads are the same. Usually HP ink cartridges (TIJ thermal foam inkjet technology) are used. The print distance is required to be within 5mm. Flat products, the printing effect will be greatly reduced, and the aesthetics and clarity are not up to the standard of close-range printing. This feature limits its scope of use to a certain extent, because the assembly line of many factories and workshops, the product to the nozzle The distance or requirements will not be within 5mm. 2. Pay attention to the drying speed and adhesion of the coding content. Regarding the product material, whether the surface is permeable, it is a very important point in the daily application of hand-held inkjet printers. The drying speed of slow-drying hand-held ink cartridges is generally about 10 seconds (permeable materials, such as paper, corrugated boxes) Except etc.), quick-drying ink cartridges, the drying speed is generally about 5 seconds. Originating from the common problem of HP ink cartridges, ink drying speed and stability have always been a contradiction. It is also a problem that users who use hand-held inkjet printers have to face. The main reason is the type of ink and the lack of the machine. The user must be cautious when choosing basic hardware configurations such as pressure pumps. It is best to have a real machine for on-site testing instead of just looking at the proofing effect and deciding to buy a handheld inkjet printer. Drying too fast will affect the normal printing of the print head. If you pause for tens of seconds or several minutes without printing, it will be very unclear after printing. The 128 nozzle holes are very easy to be slightly or severely clogged, which directly affects the coding. Print quality. Drying too slowly will be helpful for stability, but on the surface of some product materials with poor permeability, it will not be able to dry for a long time, and it will migrate by hand or friction between the product and the product, polluting the product or the environment. In the article 'What functions can the handheld inkjet printer achieveThe distance needs to be very close, which makes many of our irregular products or products with uneven surfaces unable to form a clear coding effect, which will be greatly reduced compared with good-looking samples. 3. Pay attention to the reserve of wearing parts and the advance purchase of ink cartridges. A standard handheld inkjet printer is equipped with a cartridge capacity of 42ml. If you calculate according to the content of 3 lines (printing date, batch number and other conventional information), generally one ink cartridge can print about 50,000 messages (if printing Information parameter settings, such as the resolution DPI is set to more than 300, except for the case where the number of messages will be printed less). Vulnerable parts need to be stored in advance for the handheld, including synchronizers, batteries, transmission belts, etc. When these parts have problems, if we have reserves, we can quickly restore the machine to work. If not, we need the manufacturer to send it by courier. , It will delay a lot of time. Because the handheld uses HP ink cartridges, the height of the information content printed by a single nozzle can only reach 12.7mm, which will cause some large-size content to be uncoded. If you want to print large-format content, you can only choose multiple nozzles. Splicing, the purchase cost will be greatly increased, and the amount of ink used will be doubled. The low purchase cost and high use cost are a practical problem that handhelds cannot escape. On the surface, hand-held inkjet printers do not require solvents, which can save customers, users, and factory workshops. In fact, the ink capacity of hand-held printers is very small, often only tens of milliliters, and 500 or even small print printers. Compared with 1000ML ml, the difference is far, the later use and maintenance cost is high.
