Identification of core quality ribbon belt replacement

Identification of ribbon quality:
    A ribbon judging the merits of the standard, first of all to see with base. Applied with 9 pin printer ribbon nylon base can be used with normal density, while the 24-pin printer, you must use high-density nylon belt with a base or as print-pin low-density and high density, easy to quickly rise to life with a core down, sometimes due to high printing speed printing broke a needle. On the average user, and can be placed under the lamp will be observed with nylon, with light transmission shall be ordinary density, opacity shall be high density zone. However, some such as the United States imports De produces high-density zone is opaque; while some general density zone is opaque, and which must rely on Zhuanyongyiqi Laiceliangliao. At the same time with a base should not have wrinkles, defects, cracks or visible mold.
   Commonly used high-quality nylon 66 ribbon as a belt-based materials, and some lower quality ribbon used is nylon 6. Nylon 66 and nylon 6 is the largest performance difference: the former is the highest heat temperature of 130 ¡æ, while the latter is only 90 ¡æ. Print head at high temperature before the work, certainly better than the performance of nylon 66, nylon 6. Meanwhile, the elastic recovery rate of nylon 6, poor, strike it occurs with a long ribbon to force the final death situation.
    Second, we must distinguish the good and bad ink. High-quality ink is a link to material, surface active agent, by regulating, smooth additives, UV absorbers, dyes, pigments and other ingredients made with, and leaned in with a particular base can smell the smell of ink. The bad part ribbon instead of exclusive homemade mimeograph ink printer ink, there is an approximate diesel smell the flavor. Oxidation resistance of high-quality ink higher than the poor, can not long remain imprinted faded print trace, color, extend the life of one hundred thousand draft printing characters, about an extra 30 000 characters.
    High-quality ink with a core on uniform color calm, with ink stability; inferior ink pan with a core is often a result of the surface and showed some of the luster, also of solid ink particles may be too rough and not accelerate the printing needle wear, shortened Print the use of needle
Life, or because of pH control and corrosion of the print head.
    Third, the impact of quality ribbon Another key factor is the split-mouth method and form of welding. Advanced approach to the current zone-based interface, ultrasonic welding, the thickness of no more than O.2mm, smooth interface, and no loose wires, the welding point is reasonable, weld thin; and low-grade iron ribbon is usually electricity, heating wire for butt welding zone, dislocation width of the larger, to increase weld strength, using port forwarding to reduce the angle, extending the length of split mouth method, print the needle will cause great wear.
    Another closely related with the ribbon life is the ink levels, their performance is directly printed manuscript of gray (or color depth) the extent size. Generally speaking, the higher the gray level, longer life, otherwise life is short, poor printing. So many people often infer that the higher the better the ink levels. But that is not the case, when its content reaches a certain saturation, the gray value of maintaining a constant basic, and ink levels must be kept in a moderate range. If its value is too high, it will certainly make pigments and other ingredients which settlement occurs, the viscosity increased, with a core friction
Increase, thus appear in print package with (together with a core winding) or print Wear too fast, etc., will also lead to pollution printing paper ribbon rub or print illegible; double ribbon and four ribbon or even cause string color.
    Also with excess ink, ribbon, although prolonged use, the print writing remains deep color, would mislead inexperienced user, or that the ribbon life yet to come, but in fact with the core has been broken, so that the possibility of printing needles increased by injury.
    Thus, the ink ribbon is not content the higher the better, the key is controlled by the technology of its content to the user needs to print grayscale results. For example some people like strong handwriting, while others are elegant Italian style. But the prerequisite is to ensure that the print ribbon normal life, and the effective protection of the printer.
    Finally, with a core dip when the ink content control, and mechanical properties of each part ribbon frame is a perfect match, both good and bad to judge its quality standards.

    Example to introduce the band LQ2170 core technology (LQ2170 ribbon is commonly used in domestic users, the replacement should be chosen with the core quality):
    Steps: 1. First tube frame with a seat removed from the ribbon and the core from the tube with tweezers to remove the seat belt.
    2. Thin screwdrivers or forceps gently forced open the side cover (be careful not to get behind the plastic screw cap section), clip a waste of band core.
    3. Tweezers were first removed with Department of spring (Note clamping spring, while a small hand press and hold the wind and beer whisper, so as not to bounce between the two open), and then clip out the iron with Office.
    4. Will be placed in bottom shell with a core box, the out of paper cards, take an empty box with a core. From the bottom of the column to identify with core tapped with core head, and then press the framework of the good reasons to go with a line with the core, we must pay attention to the agent was twisting.
    5. Tweezers grip the spring bottom of the 2-3 loop, set its top into the bottom of a small beer whisper, wait until the spring, then back home were out of forceps, in the process to hand to suppress a small beer Yin and spring, and finally put it back as is iron.
    6. Replace the top cover, to ensure that the end surface closely fit the same time do not suppress with a core, the core set of people with a longer tube with a seat fitted with seat tube to the frame.
    7. The direction of rotation required to gear a few times, then turn off the machine a few times, to ensure that walking with a normal, and then print.
    Generally twisted ribbon with the sub-zone and straight. Twisted with the printer directly with a printer and print head difference is the location of the printer's print head straight with the middle of the ribbon, and twisted with the printer's print head while playing in the ribbon of the upper or lower, so that you can print double-sided, Ribbon life will increase nearly doubled, while the straight with a twist with the printer with the same result, can only print one side, life expectancy did not increase.
    Ribbon is twisted or straight, is based on the structural requirements of the printer design, so in assembly with the core, we must pay attention to the original agent was twisting it, according to the framework of the correct route to go with the installation.
