I want to ask you, how to learn to repair the printing machine, there is a high level pointer, thank

General troubleshooting:

1.Paper jams. Copier jam faults account for about 60% of the failure rate, which can be observed by the paper jam indicator on the photocopier panel, and then the jammed paper is removed from the machine.

The main reasons for paper jams are: first, the paper specifications are wrong; Second, the paper is too wet; Third, there is too much carbon deposition on the transfer separation electrode wire, resulting in uneven distribution of current on the electrode wire; Fourth, the paper roller is aging. Workaround:

Replace the paper roller.

2.White, all-white phenomenon. The main reasons:

First, due to the dampness on the surface of the photosensitive drum of the photocopier, the solution: open the surface and preheat it for about ten minutes before use. Second, due to the long working time, there is too much powder accumulation on the electrode wire or electrode base, which cannot be charged or transferred normally

Clean the electrodes and replace them with new ones if necessary. If it is an electrode breakdown, the black spot can be repaired by sanding it off with sandpaper, and then consider a newer one.

3.The handwriting is lighter. The main reason for the faint handwriting of the copy is the lack of powder, and the solution: replace it with a new powder.

4.The background is dirty. The main reasons for the background dirt of the photocopied manuscript are: first, there are stains on the glass plate or dust on the reflectors. The second is that the toner cartridge has been used for too long or improperly, and the solution is to clean the stain or replace it with a new one.

Understand how it works, what each component does, and how to accumulate each fault.

With the advent of the digital age, consumer electronics are increasing in many consumer varieties...

This industry has just been born, and there are still many prospects to dig into. In fact, as long as you work hard, you can develop in any industry.

It's been a few years! Now I'm running my own store! But it's not easy to do! Run your own business! Pull the relationship! Fix it yourself! Rare! But there's less competition in this line!

You'd better look at a brand of photocopier first! More printer brands! Then learn this brand of photocopier maintenance! Printer repairs are all over the streets! There aren't many copiers!

And if you want to learn well, it will take at least 2-4 years! I'm talking about a kind of photocopier repair! Plus the printer's, in fact, everything else is pretty much the same! Most of the brands are Japanese!

Dry consumables investment is great! It's not a matter of 3-50,000!

Hey

Well, it's okay.

But this industry has to be quite technical.

It's easy to do.

I've been doing it for ten years, and I'm bored...

Restoring electronics is a matter of experience over a long period of time. The best thing to do is to practice.

Yes, as long as you want to learn anywhere, you can learn it, and you are not familiar with geographical restrictions.

Changsha, Hunan, Zhicheng Taihe company can learn, this kind of training course is very few, but also charged, generally into a company, let the master take the learning, two or three years later can be proficient.

There is nothing to memorize, the most important thing is to know its principle first, and then rely on the usual contact, plus go to the various maintenance forums on the Internet to learn

Theory to learn, photocopier structure and principle.

Mainly studying, all kinds of copying**. (Generally memorize some commonly used **.) ）

It should be said that it is okay, at least there is no problem in getting by. Because there is no risk in this line. However, it is more difficult to make a lot of money. Then again, there are champions in every industry.

The first-tier cities are saturated, and the second-, third- and fourth-tier cities are still in demand, and the overall is good.
