In the past year or two, when manufacturers promote various printers, they always remember to emphasize the concept of energy saving and environmental protection. Since it has become a hot topic of concern to the entire society, it seems that laser printers with high energy consumption can hardly attract attention if they do not use green labels. Whoever gains technical leadership in this field will gain a bigger market. This is equally prominent in the sales process of refrigerators, air conditioners and other products in the home appliance sector. A wave of “all people are environmentally friendly†is sweeping the industry. .
If you pay enough attention to the advertisements of various printers, you may find that the manufacturers are infiltrating the "energy saving and environmental protection" concept into the various performances of the products, some of which are exaggerated and some of which are simply "misleading."
Misunderstanding one: The power consumption of firing is only a little bigger than ink jet
As we all know, laser printers and inkjet printers have very different power consumption. Former U.S. Vice President and Nobel Peace Prize winner Al Gore in the book "The Truth is Neglectable," wrote: "Inkjet printers consume 90% less energy than laser printers. Actual testing The results also confirm this statement, Epson ME series ME35 continuous print power consumption is 10.1 watts, sleep power consumption is only 1.2 watts, and now the best-selling black and white laser printer HP P1108 continuous print power consumption of 360 watts, enter sleep In the state, power consumption can be reduced to 1.4 watts.
If you compare only the sleep state, the power consumption of the two printers is almost the same, but if you compare the continuous print power consumption, you will find that the power consumption of laser printers is 36 times that of inkjet printers.
According to this set of data, the choice of ink jet printer office will save 350W per hour of energy consumption than a small desktop laser machine. According to calculations, on the average day of commercial users, printers work for one hour, the conversion of 5 million laser printers from the country to ink-jet printers will save 437 million kWh of electricity and 393 million yuan of electricity.
Misunderstanding 2: Standby power consumption is more important than operating power
When a certain brand of laser printers advertised, they deliberately emphasized its “auto-switching†technology, which could significantly reduce the standby power consumption of the printer. After the printer has not received a task for a period of time, it automatically enters a deep energy-saving mode with a power consumption of only 0.6 W according to the user's settings. When the user sends the print job again, the device will automatically wake up from the sleep state and quickly Finish the print job, saving about 50% more energy than a traditional desktop printer.
Yes, in deep power-saving mode, which is off mode, power consumption is indeed 50% lower than in standby mode, but usually we will combine operating power consumption when calculating TCO cost. Although the idle time of the printer is several times longer than the running time, the power consumption of the idle state relative to the power consumption of the working state is completely negligible.
It's true that there is more than one product, and it's good to help users cultivate good habits, but when they buy printers, these technologies are not enough to influence the user's final choice.
Misunderstanding 3: excessive attention to power consumption
Running power consumption is indeed a key indicator of whether a printer is green, but it should be linked to the overall performance of the printer. For a simple example, a printer with a print speed of 12 ppm consumes 250W, another printer has a print speed of 24ppm, and power consumption is 300W. Who actually saves more power? The latter is obviously the latter, although the power consumption looks slightly higher, but it can complete the printing task faster and save power. In addition, some high-end printers have a full range of features, such as support for double-sided printing, network printing, etc. Although they will increase the power consumption of the whole machine, they will help improve the work efficiency.
The purpose of discussing the issue of energy consumption is not to tell everyone that energy conservation and environmental protection are not important, but to explain the fact that the existing technology has no obvious effect on printer energy consumption control, especially laser printers. Shout slogans, scramble concepts, catch the eye. Without changing the principle or optimizing the process, the drive engine and fixed toner still need to consume a lot of power. Manufacturers should look for breakthrough points from these two aspects.
