Gossip Crusher: Can a stylus printer really last for ten years?

Recently, someone suddenly asked me a question about the long-term use of inkjet printers on the market, especially those printers.

In fact, we have had an article devoted to this issue last year. The final conclusion is that for users with low and medium print volumes, 3-4 years is the standard life, which means that the printer will be honored to retire after the end of the manufacturer's warranty period.

For users with a particularly large print volume, it may be a problem to be able to resist the past for 2 years. This is directly related to the structure of an inkjet printer of around 1,000 yuan. Therefore, many SMEs with color printing needs consult, we are all Recommend to buy a laser printer.

So is the life of a laser printer very long?

After the fixing film prints 2-3 million pages, it will naturally wear out and need to be replaced. After the fixing roller is 30,000 pages, the rubber inside needs to be replaced.

Of course, these costs are not high and there is no need to go to the repair station. Under normal circumstances, the life of a laser printer is generally about 5-7 years. Normal maintenance and maintenance, printing 100,000 pages is not a problem.

So is the laser printer the most durable printer?

of course not. Many pin printers claim that they will not be bad for 10 years. Is this true?

The old product will not be said. Take the current best-selling Epson LQ-630KII, which emphasizes the average time-to-failure time of 10,000 hours. It is calculated according to the daily use of 3 hours and 250 working days of the year. Can be used for 13 years. It sounds a little weird.

Because of the special principle of the dot matrix printer, there is no other device that can replace it. This can be seen from the working principle of the dot matrix printer, you can see some intuitive information.

The code sent by the host is sent to the main control circuit of the printer after being processed by the input interface of the printer. Under the control of the control program, a character or graphic code is generated, and the print head prints a column of dot patterns, and the word car landscape is horizontal. Motion, resulting in column spacing or word spacing, then printing the next column, printing column by column.

After one line is printed, the paper feeding mechanism is started to feed the paper, and the line spacing is generated. At the same time, the print head returns carriage return and prints the next line. The above process is repeated until the printing is completed.

The key to the dot matrix printer is the structure of the printhead.

The structure of the print head is relatively complicated, and roughly speaking, it can be divided into a print pin, a drive coil, a positioner, an excitation disk, and the like.

When the print head obtains a current pulse from the drive circuit, the drive coil of the electromagnet generates a magnetic field to attract the print pin armature, drives the print pin to strike the ribbon, and draws a dot pattern on the printing paper.

So what is the life of the printhead?

Almost all manufacturers claim to have a life expectancy of 400 million/needle. According to senior maintenance personnel, the life of the first-line brand original print head can be close to the nominal level. Some domestic brands are hard to say, and they must be folded in half.

The brand of the deputy factory on Taobao is completely unreliable. The probability of using broken needles under heavy load is extremely high. After all, the price is only one hundred yuan. The manufacturer only dares to promise a half year warranty.

The reason why the dot matrix printer has a long life is that the structure is so simple that many high-quality Epson dot matrix printers (older models) have appeared on the market in recent years.

From the inside out, even the motherboard is a high copy. So patchwork, actually can print normally, but the life is greatly discounted.

If you pay attention to the observations, you will find that the printer models in the lobby of many tax bureaus are old models more than ten years ago. The shells have changed from white to kraft paper color, and they are still alive and have high-intensity printing instruments almost every day.

In the words of many users, "It can be used if you don't want to use it."

This is mainly because the needle printer repair is very simple, it is easy to find the source of the fault. For example, the cause of the open fault of the print drive coil is mostly the damage of the print needle drive tube on the main board, and the maintenance cost is only 2 yuan.

The mechanical failure of the car mechanism, such as belt wear, parallelism of the front and rear rails, etc., maintenance costs up to 100 yuan.

It takes three years to repair and use it for more than ten years. It is normal. Of course, there is still a premise, that is, the printer that was paid for in the past was not a bargain.

Senior maintenance personnel also said that the dot matrix printer usually gives a very solid and durable feeling. In fact, there are many details to be aware of in daily use.

Shortage of life is also a high probability event if used violently. For example, you should pay attention to adjust the paper thickness adjustment switch to the appropriate position. Different papers have different scales. You can't adjust the handle too low, otherwise it will easily cause broken needles or paper jams.

In addition, the dot printer has a large printing force, which causes many users to have the illusion that the medium can be hit by the needle, and the thickness is not limited, which is a big mistake.

Need to strictly follow the instructions on the instructions, if the thickness exceeds the standard, it is easy to cause paper jam, ribbon guide vane deformation, the most serious direct print head break.

Some media are very soft, such as wax paper, which can easily cause damage if it is in direct contact with the printhead.

Some users have a bad habit of using them until they can't find the color, only to think about whether the ribbon should be changed.

Does this really maximize the use of consumables?

NO, the damage to the print head is extremely great. The correct way to do this is to change the ribbon in time as soon as you find that the printed print is lighter during daily use.

Really want the ribbon to turn white, when lifting the hair, I am afraid that it is not far from the print pin break, do not go to fight the character.

In addition, some people will buy some cheap ribbons in order to make them cheap. If the printing effect is not good, the unsmooth interface will cause the printing needle to fail to return in time, which will cause serious wear, hang-up or even break. Print the needle.

Some people say that weight loss is seven points to eat three points practice, in fact, the printer belongs to seven points to raise three points.

If you go to the second-hand market, you will find that after the maintenance of the dot matrix printers that have been eliminated by the government banks, the functions are intact and there are no problems for a few more years. Therefore, the selection is very important, and you always have a valuable reason.
