What are the precautions when buying toner cartridges?

When buying selenium drums, it’s better to buy brand goods. After all, in the area of office products, manufacturers still attach great importance to their brand image. Suggestions that you can go to brand stores or to ensure that the manufacturer’s direct sales of the Colip Mall selection, are quite good choices. It can be said that the process of buying toner cartridges is actually the process of distinguishing genuine and fake toner cartridges. The poor quality of selenium drum charcoal powder usually results in poor printing quality. It is easy to overlap the ink deposited inside the printer, which has a negative impact on the photosensitive drum and printer.

In addition to the appearance of “observation” to identify true and false selenium drums, but also through the most direct printing effect to distinguish true and false selenium drums, when it is best to take the original drum output sample for effect comparison. The printing effect of true and false selenium drums is far from each other. When put together, there will be a sharp contrast. Under normal working conditions, the text lines printed by the original drum are very clear. If it is color playing, the color restoring ability is good, and the image is full and bright. In the printing of counterfeit products, line breakage, inadequate color restoration ability and word breakage occur when printing a large number of words.

How to identify the quality of toner cartridge before use it?

It is difficult to distinguish true from false. Here’s a detailed introduction to you: how to pick up the toner cartridge? 1, first of all, we should carefully observe its outer packing. You will find that the outer packaging of the original selenium drum is usually printed beautifully, brightly colored, and the serial number on the back is printed with special technology. When you look carefully, the background of the serial number will have a rectangular offset frame, while the serial number of the counterfeit product has no trace of such offset printing, and the counterfeit product is usually gray and printed. Blurred image and rough quality, there is a big gap between genuine and external packaging printing.

Then take a look on the inner packing of the toner cartridge. Generally, the inner packing of the toner cartridge is black or silver electrostatic packaging bag. Choose not to re seal, seal or seal the size of the two sides of the phenomenon. The electrostatic packaging bags of counterfeit selenium drums are thin and crisp. The whole packaging surface is not smooth and smooth enough. Some of them have rubbed or unclean marks. Many counterfeit products have problems of sealing and re-sealing at the seals.

Do you know how to choose the paper for printing?

Self-adhesive paper comes from Japan, and compared with sulfuric acid paper, it is matte and thinner. It is easy to stick with adhesive tape. However, the printing effect of inkjet printers is very unsatisfactory, there will be very obvious ink beads, saturation is very low, it takes a long time to dry, and use the hand will rub ink. However, the above problems do not exist when using laser printers, and vice versa.

Choose direct seal consumption, or print black and white, high-quality patterns, such as digital English.

Summary: It is recommended that inkjet printers do not use self-adhesive paper, laser printers are very recommended to use self-adhesive paper printing.

Self-adhesive art paper, simply speaking, is a common printing paper with backing glue, which can be written, because it is easy to paste with backing glue. The saturation is very high. It is very suitable for printing details. It’s a piece of paper that I personally like very much. I will print it with photos.

Conclusion: high saturation can be used in writing.

Kraft paper self-adhesive pape, divided into two kinds of deep leather and shallow leather, color and touch are not the same. Similar to Muji, the bags are light hide and smooth paper. Deep leather has a rough touch and I don’t know how to use it.

Conclusion: I usually use shallow calf self-adhesive pape.

What printers are suitable for small print shops

For a print shop, buying a multi-functional printer is more cost-effective than buying multiple single-function devices. If you are planning to open a small print shop, I would like to give you some advice:

1. It’s better to choose multifunctional printer

A multifunctional printer is often much cheaper than buying a copy machine, a scanner and a printer alone, and it saves you more space.

Multifunctional printers are not expensive at present. Prices range from $500 – $2000, depending on the printer’s function, printing speed, brand and so on. In addition, to open a printing shop, you should choose a color printer, instead of a black and white printer.

Generally speaking, inkjet printers print color photos better, but the printing speed is slower, while laser printers are suitable for printing general documents, and the color reductivity is slightly worse than inkjet printers. But laser printers are fast. If your print shop is located near the school, laser printers are more suitable.

2. Choose a ink or toner cartridge that are easy to find

Find a ink or toner cartridge easy to find and low cost. Because ink and toner cartridges are the most expensive part of printers. If you buy a new printer, only the original toner cartridges can be selected, and you will find that the new ink or toner cartridges are generally expensive and difficult to find. I suggest you buy a printer, which is mature and having more choose with compatible ink or toner cartridge, it will save you more money.

3. In addition, you should consider some additional conditions

For example, it is better for a printer to print on both sides than on one side. It is better for a printer to print multiple sizes of paper than to print only one size of paper.

In conclusion, I recommend HP M476 series printer. Although the printer is expensive, it is a set of Print, fax, scan, copy printer. In addition, if you buy compatible HP 312X toner cartridges in V4ink, only $17.99 for black and $49.99 for full 4 color set. It is a cost-effective printing device. It will save you a lot of money in the long run.

Prospects of laser printer

Laser printers were invented by Xerox in the late 1960s.

Electro-photo-graphy technology is used. The technology uses laser beam scanning drum to make the sensing drum absorb and not absorb toner by controlling the switch of laser beam. The drum then transfers the absorbed toner onto paper to form the printing result. The whole printing process of laser printer can be divided into three stages: controller processing stage, ink shadow and transfer stage. Laser printer was invented very early, but its popularization and popularization began in the early 1980s, and it has been developing rapidly in the past two years. The development of laser printers includes the following aspects.

(1) Prices have fallen sharply

The original laser printer was a luxury that most people could not possibly reach. In the early 1980s, Canon commercialized desktop laser printers and formed batches, which led to a sharp drop in prices. As a result, laser printers gradually began to be popularized. In turn, their popularization and promotion promoted the decline in prices. Their rapid development is rare in computers and peripheral products. In early 1997, Hewlett-Packard took the lead in further reducing the price of most of its laser printers. Other companies also cut the price one after another, making the price of ordinary laser printers nearly 3,000 yuan per unit. In 2003, a batch of thousand-Yuan laser printers headed by HP appeared.

(2) The performance of the machine core has been greatly improved.

As a key component of laser printer, the machine core includes mechanical and photoelectric integration technology. The progress of these technologies promotes the improvement of the performance of the machine core. Two years ago, the core of popular laser printers was generally 600 dpi, and the core was generally 240,000 dpi, or even higher; the speed also developed from 4 ppm, 8 ppm to 16 ppm, 24 ppm; the width was not only A4, but also printed B4, A3.

(3) Control technology is improving day by day

Controller is the soul of laser printer, which directly affects the performance of printer. The CPU used by the controller has developed from a single Motorola 68000 to RISC chip, such as Intel i960 and AMD 2900. Its processing ability has been greatly enhanced. Secondly, the PDL of laser printer has formed an industrial standard, and PostScript has become the standard of high-end laser printer. Language; HPPCL language has become the de facto standard for middle and low-grade laser printers. Laser printers either have simulation in one language or both. Thirdly, new technologies such as resolution enhancement technology (RET) and memory enhancement technology (MET), also known as memory compression technology, are emerging and are being mastered by more and more manufacturers.

Whether the future development prospects of laser instead of inkjet, or whether the two are leading the way, the industry has been debating for this reason. But this is a topic that is no longer new. After the first quarter of 2006, it became the center of discussion again. Simple theoretical discussion and “preaching” may be too empty and abstract. Therefore, we might as well make a comparison between them from several elements that must be highlighted in the printing demand. At the three levels of cost input, printing quality and speed, printing load and stability, which are most concerned by consumers, we can make a comprehensive comparison between lashing and spraying.

Features of laser printer

The technical structure of laser printing is much more complicated than that of inkjet printing, which increases the cost of the product invisibly. Therefore, inkjet occupies an obvious advantage in the early investment. Inkjet printing of entry-level only needs several hundred yuan, with individual products even lower, while black-and-white lash is hovering at the threshold of one thousand yuan. Therefore, there is a point of view that the need for relatively high early investment in the fight can not compete with the cheap spray. In fact, this view ignores a very key hidden factor, that is, spray beating is not always so low price, its product was born to universal application after a long process. On the other hand, the price of fierce beating is being explored step by step. Whether it can be reduced to the same price as that of spraying beating is unknown, but it will be sooner or later to break through the psychological price of consumers. The selling price of about 1,000 yuan is not high for commercial applications. There are many successful products on the market, such as Samsung M L-1610, which is known as “King Short” and Samsung SCX-4200, which is the smallest and lightest laser in one. The hot sales of these two products fully show that the price threshold is not as hard to surmount as expected.

Another aspect that determines the cost is the late input of the product, especially the late input of consumables. Behind the usual price reduction and sale, the significance of the product itself has been weakened to a certain extent, and the input of consumables has become the most critical factor affecting TCO. Generally speaking, the original cartridge used by inkjet printers sells for about one or two hundred yuan, and can print four or five hundred ordinary A4 text files. The average cost of printing each page is about 0.2 to 0.5 yuan, ignoring the cost of paper. The price of a toner cartridge for a laser printer is about 500 yuan (black and white), without considering the loss of selenium drum (selenium drum life is usually very high, allowed not to be included in the consumables under very strict circumstances), its conversion printing cost is less than 0.1 yuan. In this way, if you print a large number of documents, you can save a few spraying money in a month, and the advantage of the aggressive cost investment immediately emerges.

Compared with needle printer and inkjet printer, laser printer has obvious advantages.

(1) High density. Laser printers have the lowest print resolution of 300 dpi, 400 dpi, 600 dpi, 800 dpi, 1200 dpi, 2400 DPI and 4800 dpi.

(2) High speed. Laser printers have the lowest printing speed of 4 ppm, generally 12 ppm, 16 ppm, and some laser printers can achieve printing speed of more than 24 ppm.

(3) Low noise. Usually under 53dB, it is very suitable for use in quiet office.

(4) Strong processing ability. The controller of laser printer has CPU and memory, which is equivalent to the main board of computer. So it can carry out complex word processing, image processing and graphics processing. This is not only impossible for needle printer and inkjet printer, but also the difference between page printer and line printer.

A brief introduction of inkjet printer

Thermal inkjet technology uses a thin film resistor to heat less than 0.5% of the ink in the ink ejection area to form a bubble. The bubble expands at a very fast speed (less than 10 microseconds), forcing ink droplets to eject from the nozzle. The bubbles continue to grow for a few microseconds and then disappear back to the resistor. When the bubbles disappear, the ink of the nozzle retracts. Then the surface tension generates suction, pulling new ink to supplement the ink ejection area. Thermal induction inkjet technology is constructed by such an integrated cycle technology program. In piezoelectric inkjet technology, ink is ejected from a nozzle similar to thermal induction inkjet technology, but it is formed by narrowing the area where the ink is ejected. The size of the ejection area is controlled by applying voltage to one or more piezoelectric plates in the ejection area. Because ink is prone to chemical changes at high temperature, the orientation and size of ink particles are not easy to grasp, and the edges of printing lines are prone to be uneven, which affects the quality of printing to a certain extent, all of which are its shortcomings. Micro-piezoelectric printing head technology utilizes the discharging characteristics of crystal under pressure to eject ink steadily at room temperature. It has a strong ability to control ink droplets, easy to achieve 1440 DPI high-precision printing quality, and micro-piezoelectric inkjet without heating, ink will not be heated and biochemical changes, thus greatly reducing the requirements for ink. Liquid inkjet printers represent the mainstream products in the market.

Inkjet printers need a series of complicated procedures when printing images. When the printer nozzle sweeps through the printing paper quickly, countless nozzles on it will emit countless small ink droplets, thus forming the pixels in the image. On the printer head, there are generally 48 or more independent nozzles which emit various colors of ink. For example, 48 nozzles of Epson Stylus photo 1270 can emit five different colors: blue-green, red-purple, yellow, light blue-green and light red-purple, and 48 nozzles that emit black ink. Generally speaking, the more nozzles, the faster the printing speed. Different colours of ink drop on the same point, forming different duplicate colours. It is easy to understand the printer’s working principle by observing the simple four-color inkjet operation: there are 0 to 4 kinds of ink droplets covering each pixel. As shown in the figure below, different combinations can produce more than 10 different colors. Some printers can also produce 16 different colors by combining colors, such as “blue-green and black” or “red-purple, yellow and black.

How to solve the problems when printers fail to print②

What if the printer can’t print if the disk space is below 10MB. If the available hard disk space is less than 10MB (generally referred to as C disk), more space must be released to complete the printing task. At this point, click the Disk Cleanup button, and then in the File to Delete list box, select the file type to delete, and click the OK button.

What if local printer port settings are incorrect, causing printer to not print.

The steps are as follows:

  1. in the printer window, right-click the printer icon, and then click properties.
  2. Click the Details tab and in the Print to the Port below box, make sure that the printer is set to the appropriate port. The most commonly used ports are set to “LPT1” and the printer uses the USB port.

Incorrect output of program generated result in not printing.

To determine whether the output generated by the program is correct, it can be verified by printing documents through other programs. We create a new notebook file, type a few lines of text, and then click the Print command in the File menu. If you can print the test document, it is the original program you used for printing that has problems, please reinstall the program.

Printer driver damage causes printer not to print.

Sometimes, printer drivers may be corrupted, causing errors that cannot be printed. We can reinstall the appropriate driver and print it again.

How to Solve The Problems When Printers Fail to Print①

Printers can’t print because they are offline. On most printers, beside the OnLine button, there is a small light indicating the online status. Normally, the online indicator should be in a constant state. If the indicator is not light or flicker, it is abnormal. Please check whether the printer power supply is on, whether the printer power switch is on, whether the printer cable is connected correctly, etc.

How to set the printer to the default status.

The steps are as follows:

  1. Click the Windows Start menu, point to Settings, click Printer, and open the Printer window.
  2. right-click the printer icon, the system pops up the quick menu, and click “set as the default value”.

If the Printer window does not have the printer currently in use, double-click the Add Printer icon and install the printer according to the prompt.

What if the printer is in a pause print state, resulting in failure to print. The method is: in the Printer window, right-click on the printer icon in use, and then click to clear the check mark “” before the “pause printing” option.
