Needle printer ribbon selection method

[Office Partner Information Center] Introduction to the stylus printer ribbon purchase method Although the dot matrix printer is now an outdated product, in some units such as schools and household borrowing departments, it is still playing a "remaining heat" due to the spray. Ink printers and laser printers lack in the printing of transcripts, statements, bills, etc., and they also have a place in certain special fields. As the main consumables of the dot matrix printer, there is a market for it. Here are some tips on buying ribbons.

A good ribbon is not only reflected in the quality of the printed characters. At the same time, it also shows that the quality of the ribbon is about 3 million characters, and the inferior ribbon is only 100,000-200,000. In terms of the clarity of the printed characters, the quality ribbon is much better than the inferior ribbon. However, what we often overlook is that the quality of the ribbon is also closely related to the life of the printer. When the wrinkled ribbon is still used as a "cost-saving" name, when the inferior ribbon suddenly breaks, it is likely that you will be waiting for the printer to break the needle. To replace the needle of the dot matrix printer, the price will not be much cheaper than buying a new printer. If it is for the price difference of more than ten yuan ribbons, this has the consequences! Undoubtedly, I lost the watermelon with sesame seeds.

Ribbon is an important consumable for dot matrix printers. Let's take a look at how dot matrix printers work. The physical principle of the dot matrix printer is very simple, that is, using the dot striker in the print head of the printer to hit the ribbon, and the ink on the ribbon produces a printing effect on the printing medium. When choosing a ribbon, the ink becomes the primary content for us to see if a ribbon is of good quality. Many merchants will say "When you sell your own products, you can see the inks that are too much (handle and touch the ribbon, leave some ink marks on your fingers for you to see), such a ribbon will definitely have a clear effect... ..." In fact, the ink of the ribbon is a lot of misunderstanding, maybe the merchants themselves do not know. In fact, when the high-quality ribbon is touched by hand, the finger will not leave obvious traces, and the above-mentioned ribbon that can “find the oil”, the printed sample will be blurred when touched by hand, as if The same use of inferior spray ink. The reason is that such ink particles are large and difficult to dissolve into the ribbon made of dense nylon yarn, and remain on the surface, so that the hand will leave marks on the hand. Large ink particles are not only easy to print on paper, but more serious: they will enter the gap between the print heads along the gap between the print pins. Over time, they will solidify under the action of dust and block the print head. The needle cannot be flexibly stretched, causing the printer to malfunction and severely interrupting the needle. In short, when purchasing the printer ribbon, it is necessary to carefully observe whether the ink of the ribbon is coarse and has no odor, whether the dye ribbon is in contact with each other, and whether it is sticky or not, and whether it is light or touch will make you "hand full of oil", so You are ready to take the first step in purchasing a good ribbon.

Next, let's take a look at the tape base that adsorbs the ink. As mentioned above, the belt base is woven from nylon yarn. Therefore, the quality of the nylon yarn directly affects the quality of the colored belt, while the belt base woven from nylon yarn determines the color belt. Service life and ink adsorption and penetration ability. At present, there are two main types of belts in the market: nylon 6 and nylon 66. The difference between the two is that the chemical composition of nylon is different. Nylon 66 is better than nylon 6 and is durable and durable. Nylon 66 is divided into four types: low density, medium density, high density and high density. Of course, the higher the density, the more the number of weaves, the better the elasticity! For ordinary user friends, the four density bands should be distinguishable before they are immersed in the ink, but after dyeing, it is not easy to distinguish.

"Touch and slide" identification method:

Touch: Touch the base surface with your hand, it is soft and delicate, and it is better to have a smooth feeling;

Pulling: the elasticity is good when pulling, the recovery is good, and the bad belt base will have the spinning phenomenon when stretching;

Bomb: After stretching the belt base, use the middle finger to force the stretched part, and the finger feels a soft elastic force, but can not have a hard feeling;

Slip: Slide back and forth on the side of the belt with your back and back, and feel if there is unevenness or burr.

In addition to the large performance of the belt-to-ribbon performance and life, the joint portion of the ribbon is one of the elements to consider when selecting a ribbon. The joints of the high-quality ribbons are all welded by using an ultrasonic welding machine. The ultrasonic waves do not damage the fiber characteristics of the belt base, so that the joint quality can be ensured. The inferior ribbon is welded by simple hot-melt or hot-pressing method, and the joint will exhibit obvious double-layer phenomenon. The unsmooth interface will often cause the printing needle to fail to return in time, thus causing serious wear, hang-up or even broken printing. needle. So when choosing a ribbon, you must see if the ribbon connector belongs to the former or the latter. In addition, it is necessary to explain to the user's friends that even a small ribbon can not ignore the after-sales service provided by the merchant. For the production enterprise, after-sales service is the fundamental of its market, so users need to know the product when purchasing. The after-sales service of the manufacturer, in general, the manufacturers with complete after-sales service, the quality of the products produced is also guaranteed.
