How can a color LED printer print more energy

In the field of office equipment, especially printers, it is the most frequently used and most exposed consumer-oriented output device. Under the premise of advocating "energy saving and emission reduction" globally, how to effectively reduce office costs and reduce energy consumption has become a topic of concern for current office owners.

In the investigation visit, the author found that although there is a desire to save energy, but because most of the office family is not familiar with the performance of printer equipment, “how to print is more energy-efficient” in daily work is a new problem that hinders office energy saving. After summing up the experience of many office workers, the author believes that printing energy conservation should start from a large point and start small. Next, the author will use a commercial printer, the new mainstream color LED printer OKI C711dn as an example, to tell you about the successful experience of energy-saving printing.

Save on the use of supplies

Consumables are the main source of consumption for printers. Therefore, the energy conservation of printers must begin with the use of consumables. In terms of current corporate printing requirements, most of the output is required for daily office work. When printing these informal documents, the standard printing mode can be changed to the ink-saving printing mode. The specific method is to open the printer's "Properties" dialog before printing, click "Printer Preferences", there is a "Mode Select" window, where we can open the "Ink Save Mode", so the printer will Print in ink save mode. It is reported that using this method, the C711dn can not only save the use of toner, but also increase the printing speed and save energy. The printed manuscripts are more than enough for daily proofreading or passing.

At the same time, as a new mainstream LED printer for business printing, the C711dn is equipped with an LCD display for real-time monitoring of consumables capacity. When the LCD display shows "Remaining toner is low" or if the print becomes light, according to the long-term experience accumulated by the evaluation engineer, the printer can open the printer cover several times to make the toner Evenly distributed. This allows the printer's toner cartridge to provide the maximum amount of print. To avoid wasting toner and possible toner sensor errors, the user can wait until the LCD display shows "toner empty" before replacing the toner cartridge.

In addition to toner, photoconductive drums are another major consumable item in the printer. The C711dn adopts the toner separation design. The photosensitive drum can be replaced as a single consumable. In the process of using the photosensitive drum, special attention must be paid to avoid unnecessary waste. The photosensitive drum surface is easily damaged and extremely sensitive to light. In addition to being untouchable to prevent scratches, do not expose the drum to normal room lighting for less than 5 minutes, or expose the drum directly to daylight and very bright indoor lighting.

Functional use

According to surveys, the working hours of daily office printers are usually around 2 hours, and most of the rest of the time are idle. Therefore, almost all printers are equipped with a standby mode and a power-saving mode, and the C711dn has a sleep mode to solve the energy-saving problem of the idle state of the printer.

Due to the use of LED printing technology, one of the characteristics of the C711dn itself is energy saving, and the power consumption in the sleep mode is only 1.1W, and the authoritative media evaluation is even less than 1W, giving the C711dn an excellent energy-saving advantage. Fortunately, the time from C641dn to sleep mode can be set so that if the printer is not used within the set time, the printer will automatically enter sleep mode to control its power consumption. To cancel this mode, simply press the "Power Save/Resume" button on the operation panel.

In addition, the C711dn comes standard with an automatic duplexing unit, which not only saves the company 50% in paper consumption, but also eliminates the need for double-sided purchase as an option, which saves companies 1500-300 in purchase costs. Not only that, the automatic duplex unit also allows the printer to have more energy-efficient applications. Through the C711dn driver, the output format of the booklet is set in the printing preferences. The printing program will automatically typeset the output, making it easier to mount the booklet directly into a booklet. With the booklet printing method, up to three-quarters of the printing paper can be saved. At the same time, the production of brochures can make the prints look more concise and professional, and the reading is more convenient.

High efficiency is energy saving

The author believes that creating more value in a unit of time can also be regarded as energy saving, that is, energy efficiency. This has a direct requirement on the printer's print speed, home page output time, and so on. This requires the user to pay attention to the purchase of the printer, to fully consider the actual frequency of use and workload, choose the most suitable for their own printer. For example, if it is used by multiple people or departments, it is necessary to consider purchasing a network printer with a network card; for example, the workload is very small, but it is not necessary to print at high prices for high-speed printers occasionally; for example, it is only the printing of ordinary black-and-white documents. No need to buy a color printer.

Postscript: In fact, energy-saving printing technology is only one aspect of energy conservation, and the user’s awareness of energy conservation is the most important. Without the user’s concern for energy saving, even the best technology cannot be used to its maximum effectiveness. Let us work together and establish good energy-saving habits in our daily work.
