Beware of pitfalls and beware of errors in printer energy conservation

in recent oneortwo years, when manufacturers can choose digital display operation to promote various printers, they always don't forget to emphasize a concept, that is, energy conservation and environmental protection. Since it has become a hot topic of concern in the whole society, it seems that high-energy laser printers are difficult to attract attention if they are not labeled as green and environmentally friendly. Whoever can get the leading technology in this field will get a larger market, which is also prominent in the sales of refrigerators, air conditioners and other products in the field of household appliances. A trend of environmental protection for all is sweeping the whole industry

if you pay enough attention to the advertisements of various printers, you may find that manufacturers are infiltrating the concept of energy conservation and environmental protection into the performance of products, some of which are exaggerated, and some of which are even misleading at all

myth 1: the power consumption of percussion is only a little larger than that of inkjet

as we all know, there is a great difference in power consumption between laser printers and inkjet printers. AlGore, former vice president of the United States and 2007 Nobel Peace Prize winner, once wrote in his book "an inconvenient truth": inkjet printers consume 90% less energy than laser printers. The actual test results also confirm this statement. The continuous printing power consumption of Epson me series me35 is 10.1 watts, and the power consumption when entering sleep state is only 1.2 watts, while the continuous printing power consumption of HP p1108, the best-selling black-and-white laser printer at present, is 360 watts. When entering sleep state, the power consumption can be reduced to 1.4 watts

if you only compare the power consumption of the two printers in sleep, it is true that the power consumption of the two printers is almost the same, but if you compare the power consumption of continuous printing, you will find that the power consumption of laser printers is 36 times that of inkjet printers

according to this set of data, choosing an inkjet printer for office will save 350W of energy per hour compared with a small desktop laser machine. It is estimated that, based on the average day of commercial users and one hour of printer work, converting 5million laser printers into ink-jet printers in the country can save 437million kwh of electricity and 393million kwh of electricity per year

Myth 2: standby power consumption is more important than running power consumption

a brand of laser printer deliberately emphasized its automatic on-off technology when it was advertised, which can significantly reduce the standby power consumption of the printer. After the printer has not received the task for a period of time, it will automatically enter the deep energy-saving mode with a power consumption of only 0.6W according to the scenario set by the user. When the user sends the print task again, the device will immediately wake up automatically from the sleep state and finish the print job quickly with serious product homogenization, Compared with the barrier performance of the new generation of clear film and coating of the traditional table, it starts to save about 50% of the energy consumption to the proximity printer of thin metal sheet and aluminized film

yes, in the deep energy-saving mode, that is, in the shutdown mode, the power consumption is indeed 50% lower than that in the standby mode, but usually when we calculate the TCO cost, we will combine the operating power consumption. Although the idle time of the printer is several times longer than the running time, the power consumption in the idle state is completely negligible compared with the power consumption in the working state

it's true that a little makes a lot. It's right to help users cultivate good habits, but these technologies are not enough to influence users' final choices when buying printers

myth 3: pay too much attention to power consumption value

running power consumption is indeed a key indicator to measure whether the printer is green or not. Some American friends of the author said that it should be linked with the overall performance of the printer. For a simple example, a printer with a printing speed of 12ppm consumes 250W, while another printer with a printing speed of 24ppm consumes 300W. Who on earth saves more power? Obviously, it is the latter. Although the power consumption looks slightly higher, it can complete the printing task faster and save more power. In addition, some high-end printers have comprehensive functions, such as supporting double-sided printing, network printing, etc. Although they will increase the power consumption of the whole machine, they are of great help to improve work efficiency

the purpose of discussing energy consumption is not to tell everyone that energy conservation and environmental protection are not important, but to illustrate the fact that the existing technology has no obvious effect on printer energy consumption control, especially laser printers, which are more just shouting slogans, speculation concepts and attracting eyeballs. Without changing the principle and optimizing the process, the driving engine and fixed toner still need to consume a lot of power. Manufacturers should look for breakthroughs in these two aspects
