Life 1984

Chapter 34 Go away!

Shen Xiulan was watching Li Yunhai busy making his own transformer. She couldn't help him much, so she kept fanning him with books.

In this old-fashioned community, the trees in the yard are tall and leafy, and the rooms on the first floor are quite shady.

Shen Xiulan fanned her a little, and Li Yunhai became less hot.

"Yunhai, what are you doing with so many twists and turns?"

"This is a transformer that can convert the 220V voltage of our mains into 110V voltage."

"Why switch?"

"Copy machines all use Japanese power supply standards. They cannot be used without converting the power supply."

"Do you need such a big transformer for each copy machine?"

"I made this for testing machines. I will modify the circuits in the machines for sale."

"It's amazing! Can we test the machine now?"

"Okay. I'll plug in the copier and give it a try."

Li Yunhai plugged in a copy machine.

Then, with excitement, he pressed the start button of the copier.

no response.

This is also expected!
If it were so simple, just replace a transformer and it could start running, wouldn't it be too cheap? Li Yunhai?
There must be a reason why capitalists can treat these machines like garbage!

Shen Xiulan looked at the copier and asked Li Yunhai, "There's no sound! Is it the transformer that's not working? Or is there something wrong with the machine?"

Li Yunhai smiled and said: "There is no problem with the transformer. I have tested it. I still need to repair this copier."

Shen Xiulan thought for a while and said: "Yunhai, would you like to try it first to see which machines can be turned on after being powered on?"

Li Yunhai nodded and said: "This is a good idea! If it can be powered on, it must be easier to maintain."

Liu Shitao gave him a week, and four days have passed!

In the next three days, Li Yunhai must repair five copiers.

The room is a bit small and the photocopiers are piled high.

Li Yunhai conducts a power test on one of his units.

When she tried the third machine, Shen Xiulan pressed the start button and the machine rang.

Shen Xiulan was even happier than Li Yunhai, and she shouted joyfully: "Yunhai! This one is good!"

Li Yunhai is not as blindly optimistic as she is.

"Not necessarily! Xiulan, I bought copy paper. You can take out a few sheets and try them out."

Shen Xiulan happily opened a pack of copy paper, carefully took out a few pieces of white paper, looked at the copier and asked, "Yunhai, where should I put this copy paper? I don't know how to use it."

Li Yunhai opened the cover of the copier, pointed at a piece of transparent glass and said, "This is called the platen glass. The original document we want to scan and copy is placed here. Did you see that there is a red dot on the upper left side of the glass? , the document material should be aligned with the red dot and placed flatly on the glass surface. Remember, the text surface we want to scan must be placed downward. Then cover the cover. This is the control panel, because It’s a Toyo copier, so the panels are all in Japanese, I’ll teach you one by one.”

Shen Xiulan is very smart. Li Yunhai teaches her once and she learns it.

What she was even more curious about was how did Li Yunhai know this knowledge?
"Unkai, how do you know so much? And how do you know these Japanese words?"

"Uh-" Li Yunhai scratched his head and smiled, "When I bought a copier, I asked the boss there for advice. The copiers we import have either English panels or Japanese panels. As for copiers from Hong Kong and Taiwan, they use is in traditional Chinese characters, I believe you can recognize it."

Shen Xiulan's eyes sparkled with admiration: "Yunhai, you are so amazing!"

Li Yunhai continued to teach her: "No matter what type of copier it is, the symbol is the power button, which is used to start the machine. The up and down buttons are used to adjust the number of copies. This big green button has two page styles on it. The green mark is the copy key, which is the copy execution key. The red key is the stop key, which can also clear the incorrect number of copies entered. The yellow key is the clear key, which is used to restore the power to the power on state."

He teaches you key by key and demonstrates the operation step by step.

Shen Xiulan learned it quickly.

She found an old newspaper, placed it on the glass plate of the copier, and put the copy paper into the feeder.

Li Yunhai said: "Xiulan, the copier has completed its warm-up work, you can make copies."

Shen Xiulan asked: "Why does it have to be warmed up?"

Li Yunhai explained: "This is a laser copier. When copying, you first need to charge the photosensitive material, and use the corona discharge method to bring a certain amount of electrostatic charge to the surface of the photosensitive material, so that normal copying can be performed. The time this process takes is called the copier’s warm-up time. Generally, it only takes one and a half minutes.”

Shen Xiulan didn't seem to understand, but she knew that after the copier was turned on, it only needed a minute and a half to warm up.

She pressed the green copy button.

no response!

"Yunhai, no! I can't copy!" Shen Xiulan was anxious and pressed the copy button several times, but there was still no response.

Such a failure was also expected by Li Yunhai.

In his opinion, these machines must have some kind of malfunction, otherwise they wouldn't be sold as garbage.

He checked the machine and said helplessly: "The copying life of the copier has expired!"

Shen Xiulan asked: "How long is the copying life of the copier? How do you say it?"

李云海道：“复印机都有一个设计寿命。根据机器的档次不同而不同。档次按每分钟复印速度来算。一般每分钟复印20张以下的设计寿命在40万张左右。50张以上的在300万左右。60张以上的在600万左右，像这种高质量的机器，最高可以达到900万张。”

Shen Xiulan groaned: "When the life of the machine expires, it is a scrapped machine? So, this is foreign garbage? Yunhai, you have been deceived!" Li Yunhai laughed and said: "When scrapped, it is only for customers. As long as it is scrapped. If it can be reset, or parts can be replaced, there will never be a scrapped machine for maintenance personnel!”

Shen Xiulan had no idea how to deal with these complicated imported machines. She had just learned how to operate them.The more this happened, the more she fell in love with Li Yunhai.

Li Yunhai found the problem with the machine, which made it easy to repair.

He first tried to reset the copier's life by clearing its counter.

The counter of the copier will record the number of times used and the number of sheets. When the counter reaches a certain value, the copier will stop working and needs to be repaired or parts replaced.Clearing can extend the service life of the copier and reduce the number of repairs or replacements.

Li Yunhai successfully cleared the counter.

Clearing is a task that requires careful operation. If performed carelessly, it may cause equipment damage or data loss. Most people will not do this task.

Li Yunhai also reset and cleaned the fuser of the copier, replaced the toner cartridge, and reset the toner cartridge.

Shen Xiulan stayed by her side the whole time, watching curiously, unable to understand, but not aware of the seriousness.

It seems that many people have a natural curiosity about this kind of complex high-tech machine maintenance, and they can spend so much time watching it that they forget to eat or sleep!Just like a child watching the work of an excavator, he can watch it all day long.

Li Yunhai finished the operation and asked Shen Xiulan to test the machine again.

Shen Xiulan plugged in the power, turned it on to warm up, and put in documents and copy paper.

After the copier was warmed up, she pressed the copy button.

A soft sound.

This is the sound of the pickup roller rubbing!

It worked!
The copier is working!
Shen Xiulan held the copy paper at the paper outlet and smiled like a child who got lucky money: "Yunhai, look, you can copy! You are so awesome, aren't you? This can also be repaired!"

Li Yunhai took the paper, looked at it over and over, and said, "Not bad! The copy is very clear, without black lines or ghosting! This machine has been repaired successfully!"

Shen Xiulan asked: "Can this machine be sold for more than 2 yuan?"

Li Yunhai pondered: "Let's discuss the price with Liu Shitao then! My psychological price is 1 yuan per unit, which is the lowest!"

Shen Xiulan let out a wow, then covered her mouth with her hands, her eyes shining brightly: "Yunhai, if you sell a machine like this, you can become a household worth ten thousand yuan!"

Li Yunhai laughed out loud.

He spent more than an hour thoroughly cleaning and caring for the copier.

This is the first machine he wants to sell in his life. Although it is sold as a second-hand mobile phone, he must try his best to ensure the condition and quality of the product.

The last step is to modify the power supply.

Li Yunhai converted the power supply of the copier from 220V to 110V.

After his repairs and modifications, this copier can work using mains electricity!
Li Yunhai removed the homemade transformer and plugged the copier directly into the socket.

Power on!
copy!

everything is normal!
Li Yunhai clenched his fists, raised his arms, and stroked hard, saying "Yes!"
A Ricoh copier, which was originally a piece of foreign junk, was bought for 90 yuan. After being repaired by Li Yunhai, it was successfully resurrected and turned into a second-hand product worth over [-] yuan!

You can earn dozens of dollars repairing a typewriter.

Repairing a copy machine can earn you a few hundred to 1000 yuan.

These businesses, which are very profitable in the eyes of others, are nothing compared to buying and selling second-hand copiers!

The successful repair of the first copier gave Li Yunhai great confidence and energy!
"Yunhai, are you hungry?" Shen Xiulan pouted and said, "It's almost dark! We haven't had lunch yet!"

It turned out that without even realizing it, a day slipped away so quietly.

Li Yunhai concentrated on the repairs, completely unaware of fatigue and hunger, nor did he know that time passed so quickly.

"I'm hungry! I'm so hungry that my chest touches my back! Thank you for your hard work, Xiulan, I'll treat you to a restaurant!"

"Don't go out to the restaurant! It's not easy for you to make some money, and you have to invest so much. Every penny less is worth it. How about you come to my house for dinner?"

"No." Li Yunhai shook his head quickly, "I'm afraid your mother will say something about me."

"Puch! What are you afraid of? My mother doesn't eat people."

"Xiulan, I only have two days and I have to repair 4 copiers. I may have to work overtime tonight."

"Oh, okay then, let's eat rice noodles, shall we? You can be full for just two cents!"

Li Yunhai agreed, washed his hands, wiped his face, and went to the noodle shop with Shen Xiulan and ordered two bowls of chili fried pork noodles.

At this time, a lewd laugh came from the side: "Hey, isn't this the campus beauty of the engineering school? Hehe! We are really destined! Miss campus beauty, have you graduated? Can you date us? "

Shen Xiulan turned around and saw that her beauty was pale!

Li Yunhai's sharp gaze slowly swept over the two men.

Enemy road is narrow!

The visitors were none other than the two basketball players from the Civil Affairs School, who had molested Shen Xiulan two years ago!
One of the young men with a middle parted hair stretched out his hand and wanted to slap Shen Xiulan on the shoulder.

Li Yunhai stood up suddenly, and before the other party could touch Shen Xiulan, he grabbed the other party's wrist, raised his handsome eyebrows, and shouted in a deep voice: "Get out of here!"
