Epson recently launched the WorkForce Enterprise WF-M20590 black and white ultra-fast micro-jet copier, designed for enterprises with a monthly print volume of more than 25,000 sheets, using fast-drying waterproof pigment ink, can print 100 A4 files per minute, and consumes only 180W of power. It is quite competitive in terms of production capacity, quality and environmental protection. The little devil also experienced it for the first time to confirm the performance of this machine in terms of printing speed, quality and power consumption.

Although the M20590 is called a copier, it is actually a large-scale multi-functional machine with functions of scanning, printing, copying, and faxing. Generally referred to as a multifunctional machine, it refers to a relatively small table with relatively small toner and ink capacity, which is suitable for small offices. Larger floor-standing models with higher print quantity, size and lifespan are called business machines or copiers.

●Appearance function

Appearance of the Epson WorkForce Enterprise WF-M20590 black and white ultra-fast micro-jet copier.

The M20590 has two places to put originals, the top ADF (Auto Document Feeder, automatic document feeder), and the work platform after the ADF is opened. The ADF can hold paper sizes from A6 to A3/Ledger (up to 297x431.8mm), paper thickness from 52 to 128g/m², and a loading capacity of 150 sheets or 16.5mm. It can copy and scan multiple originals at one time, and can make two-in-one copying. If the width of the originals is the same, it can also scan documents of mixed sizes, such as A3/A4 scanning together, B4/B5 scanning together. ADF is not suitable for placing originals with crepe, binding holes, just printed, etc., there is a risk of paper jamming, and a working platform should be used to handle such originals. The handle on the left is used to open the ADF and clear it when the paper is jammed. The space below the ADF feeding platform is where the originals are recycled.

This is the work platform for copying and scanning irregularly shaped originals, thicker originals, cardboard boxes, etc. The maximum paper size suitable for the working platform is 297x431.8mm, and the maximum weight is 2Kg.

The glass on the left side of the working platform is for double-sided scanning. M20590 has two scanning AQV255 model">AQV255 model">AQV255 model">AQV255 model">AQV255 model">AQV255 model">AQV255 model">AQV255 model">AQV255 model">AQV255 image sensor, one in One under the working platform and one in the ADF. During double-sided scanning, the image sensor under the working platform will move under the left glass, the original will be put in from the ADF, and the first side will be scanned from above through this glass, and then sucked into the ADF. Scan the second side in the middle, and finally the original comes out from the position below the ADF. Because there are two image sensors, it can scan both sides of the original at one time, and the speed can reach 60ppm/110ipm.

The space below the working platform is called the upper paper output slot, and the printed products will come out from this side.

The upper output bin can also be opened to remove jammed paper.

There are also two places for feeding paper, 4 trays under the front of the machine, and a universal tray on the right side of the machine. The paper entered from the universal tray will come out from the lower left output slot after printing.

The maximum printable paper size of the M20590 is A3+, which can only be loaded from the universal tray. Universal tray can hold up to 161 to 350g -ic/" title="350g model">350g-ic/" title="350g model">350g-ic/" title="350g model">350g-ic /" title="350g model">350g-ic/" title="350g model">350g-ic/" title="350g model">350g-ic/" title="350g model">350g-ic/" title="350g model">350g-ic/" title="350g model">350g/m² thick paper, the capacity can be up to the position marked by the triangle symbol on the paper positioner, about 80g/m²: 150 sheets Plain paper or 30 sheets of thick paper.

The lower paper output slot is a three-stage telescopic design.

The paper tray under the front of the machine can hold up to 80g/m²: 550 sheets of plain paper, and it cannot exceed the height limit of the triangle symbol on the locator. The paper is fixed by the left and lower paper positioners. When placing paper of different sizes, the upper blue lock switch must be turned on before the positioner can be moved, and the positioner must be locked after moving.

The whole machine can hold 550x4+150x1=2,350 sheets of plain paper in total with 4 trays + 1 universal tray. If a high-capacity paper feeder with a capacity of 3,000 sheets is added, the maximum paper feed capacity of the entire machine can be upgraded to 5,350 sheets.

A sticker is attached to the upper cover of the ADF, indicating the code of each part of the machine, which is used to identify the position of the paper when the paper is jammed.

Under the LCD control panel at the front of the machine is the ink cartridge cover, which contains 2 black ink cartridges, 1 ink cartridge can print 60,000 sheets, and 2 ink cartridges can print up to 120,000 sheets, but you must install 2 ink cartridges, not just 1 ink cartridge. The M20590 uses the new DURABrite Pro Ink non-permeable, fast-drying, waterproof pigmented ink designed for high-speed printing. The plain paper will be waterproof soon after printing, and you can also use a highlighter to draw lines without sticking.

Epson also launched an identical color printer, the WF-C20590. In addition to 2 black ink cartridges, 3 color ink cartridges can be placed, and the print volume can only be limited to 50,000 sheets due to the color ink limit.

To the left of the C1 tray is where the waste ink collection box is placed.

The waste ink collection box is longer than the ink cartridge and is designed to have a high capacity and reduce the number of replacements.

The control panel is a 9-inch TFT color LCD screen that supports touch. Below the paper clip storage area on the left is a reserved space, which can be opened and inserted into the HID proximity card reader, which provides the function of card permission control, and can also limit the print file format. However, the card permission control must cooperate with the pre-press management purchased by Epson. The system does it. The NFC icon on the right side of the control panel is used for mobile printing. The mobile phone with NFC function can download and install the Epson iPrint App to print the data in the mobile phone by induction. From the bottom left of the control panel: power indicator, fax receiving indicator, error indicator, data indicator.

The control panel can be lifted up to a near vertical angle.

There is a USB 3.0 port under the reserved space, which can read, scan or store data in external USB devices such as MO drives, hard drives, and USB flash drives. Supports MO drives with a maximum capacity of 1.3GB or 2TB hard drives .

There are three ports on the rear right side of the machine, starting from the top: USB Type-B port, LAN Ethernet port, EXT. port for external phone, and LINE port for telephone line. The Ethernet network speed supports 1000Base-T/100Base-T/10Base-T, and there is also a built-in 802.11b/g/n Wi-Fi wireless network, which can be connected by Wi-Fi Direct.

Epson provides a wealth of network printing services. As long as the M20590 is connected to the Internet, you can log in the machine information from the Epson Connect website, use Email to send letters to print remotely, use Line, Google, Apple services to print, mobile phone induction printing, or Scan to cloud, etc.

Below the network port is the power socket.

The small cover on the lower left and right sides of the machine is opened to connect optional equipment, such as Finisher unit finisher, High capacity tray, etc. Epson also offers other options such as the Paper Cassette Lock, which locks the trays for management.

●Control Panel

The control panel is not only an interface for copying, scanning, and faxing, but also functions for system settings, authority management, and machine status inspection. The following key screenshots are captured so that you can quickly understand the situation, and the operation video of all the interfaces is also attached for viewing.

This is the home page of the control panel, from the left of the toolbar in the upper right corner: printer status, network connection status, volume setting, sleep mode, description. If there is a small door icon after the description, it means that the function has permission control, and the small door icon provides the login and logout functions. The largest area in the center is the function selection area, and the position and order of the icons can be customized. Status column in the lower left corner from left: the number of unprocessed faxes, job status (working and waiting jobs), suspending the current job can also interrupt another job, paper settings.

●Features

This copier emphasizes high productivity, print quality, low power consumption, healthy green energy, etc., all from the PrecisionCore micro-jet printing chip developed by Epson itself.

PrecisionCore Linehead printing head used by Epson WF-M20590.

At present, the mainstream of inkjet technology is piezoelectric type and hot-bubble type. Piezoelectric type uses voltage to control the mechanical structure of piezoelectric material to inject ink, and hot-bubble type uses heated ink to generate foam to inject ink. Because the piezoelectric type does not need heating, it can reduce the influence of thermal energy, and at the same time reduce the limitation of ink types, Epson chooses to develop towards the former.

In 2007, Epson developed thin film piezoelectric TFP (Thin Film Piezo) technology, which became the starting point of PrecisionCore. In 2013, the PrecisionCore Micro TFP printing chip was developed, which is also called "fine point micro-jet printing chip" in China. Each printing chip is about 1.33 inches in length and has 2 rows of 800 nozzles. Each nozzle has a maximum of 800 nozzles per second. It can eject 50,000 ink droplets, and the ink droplets can be controlled to a minimum of 1.5pl.

Since then, Epson has developed a variety of printing heads from home printers to digital textile machines with the fine-point micro-jet printing chip as the core. The PrecisionCore Linehead printing head used by the M20590 was developed in 2017. It consists of 36 fine-dot micro-jet printing chips in an oblique array. It does not need to move back and forth during printing, so it can have a resolution of 600 x 2400dpi and 100 pages per minute of A4 paper. printing speed.

Because no heating brings many advantages. First of all, there is no need to warm up the machine. Compared with laser printers and thermal foam printers, it has a shorter printing process. The first printing only takes 6.2 seconds, and there is no need to wait for the ink to cool during the process. No heating reduces energy consumption. M20590 single-machine copy power consumption is 180W, standby mode is 77W, sleep mode is 1.1W, and shutdown mode is 0.2W. Compared with 45-55ppm laser printers of the same level, the power consumption is only 1/8. The heating-free printing head is not a consumable material, and there is no need to regularly replace parts such as the photosensitive drum, transfer belt and heater, which can reduce the environmental burden of manufacturing and recycling, and reduce maintenance downtime. And because the overall structure is not heated, it is safer to maintain the machine or remove the jammed paper without burning it.

●Actual measurement

First, let's test the high-speed printing known as 100ppm. We actually recorded the process of copying 100 sheets of A4 paper to see how long it took. Epson WF-M20590 black and white ultra-speed micro-jet copier 100ppm test.

Judging from the recording time of the film, the time from pressing the copy button to the first sheet of paper is about 9 seconds, and there is a short pause after the first, 33, and 69 sheets of paper come out, and the entire printing time is about 1 minute and 10 seconds. . There will be a time difference in the first printing, because copying from the machine instead of printing will increase the scanning time, which is different from the case of printing directly from the computer.

Let's take a look at the power consumption part. The actual power consumption in sleep mode is 0.7W.

72W in standby.

196W when copying.

The official power consumption is 1.1W in sleep mode, 77W in standby mode, and 180W in stand-alone copying. In contrast, the measured sleep mode and standby power consumption are lower than the official announcement, and higher when copying.

Waterproof test, copy a copy on the spot and sprinkle it with water immediately, wait a few seconds to see what happens. We waited for more than 20 seconds and then deliberately wiped it with our hands, and there was indeed no fainting. It is also found that the speed of printing the first sheet has become about 5 seconds, which is faster than 6.2 seconds. Next is the highlighter test, which also passed the test smoothly. Finally, we experience mobile phone NFC induction printing.

Because it is the first time to pair and use, there are many steps in the process, including manually logging in to the designated printer and selecting paper cassettes. When you start using it for the second time, you only need to select a photo/file after induction and press the print button.

●Summary

The Epson WF-M20590's greatest competitiveness lies in the PrecisionCore micro-jet printing chip. From this core technology, the advantages of high speed, low power consumption, low maintenance cost, environmental protection and energy saving are derived. The paper flow design for double-sided scanning and double-sided printing is also good. One action can accomplish two things. If there are often a large number of double-sided processing jobs, it should save a lot of time.

In terms of functions, standard enterprise needs such as high-speed printing, low energy consumption, easy maintenance, permission control, and cloud printing are all taken into account. Epson also provides pre-press management and post-press management services to help improve productivity and reduce costs. However, the needs of each department in the enterprise are different, and the choice must be made according to the needs of the department.

It is worth mentioning that nowadays, the world pays more and more attention to environmental protection issues. Epson has long communicated the concept of "cherishing the earth's resources", which is also reflected in its products and technologies. For example, inkjet printers that reduce printing costs and energy consumption, recycling paper machines that companies use to recycle and recycle their own paper, and printer ink-collecting cotton made from recycled waste paper. WF-M20590 also performs well in terms of environmental protection, meeting the three UN Sustainable Development Goals (SDGs): improving energy efficiency (Goal 7), increasing economic productivity (Goal 8), and sustainable production and consumption (Goal 12).

The official website of the Epson WF-M20590 ultra-fast micro-jet copier shows a price of 1,575,000 yuan, but it is generally used in a rental plan, with a monthly printing volume of about 25,000 sheets. business or on the official website for inquiries.
