BUYERS LABOctober 2015 A Comprehensive BLI Laboratory Evaluation

The highly reliable Samsung MultiXpress K7400LX stood out in many ways during BLI’s lab evaluation. It’s based on an engine that completed our rigorous 200,000 impression/20,000-scan durability test with just one misfeed and no service calls required. The K7400LX proved to be an ideal choice for organizations looking for top-quality output, particularly in print mode, earning our highest rating in every print quality category—an extremely rare feat. Further, the device can be counted on to keep workers moving, with lightning-fast duplex scan speeds and above average results in a number of other productivity tests. In addition, the unit offers numerous time-saving conveniences, such as a choice of three different copy interfaces and the rarely seen abilities to scan during a misfeed and access the display while originals are being scanned. The feedback and web utilities are both simple to navigate and offer more advanced functionality than many competitors; the feedback utility is the first in the market to offer Twitter alerts. Although priced higher than average, the K7400LX includes high memory, hard drive and maximum paper capacities, along with heavy media weight support. Taking all of these factors into consideration, BLI highly recommends the Samsung MultiXpress K7400LX for environments with monthly volumes of 26,000 impressions.

Samsung

MultiXpress K7400LX*40 PPM Black Print • Scan • Copy • Fax

AT A GLANCE

Test duration: Two months, including a 200,000-impression and 20,000-scan durability test.

Maximum monthly duty cycle: 200,000 impressions.

The maximum monthly duty cycle is the maximum volume, as specified by the vendor, that the unit is capable of producing in a month; however, it isn’t recommended that it be run at this volume on a regular basis.

Average optimum monthly volume for devices in this speed range: 26,000 impressions

Based on a survey conducted by BLI. When comparing models, note that this lower optimum volume was instituted in May 2012. Optimum monthly volumes for models tested prior to May 2012 may differ.

* Reliability, print/copy productivity and image quality results are based on the performance of the Samsung MultiXpress K7400GX, which uses the same engine, but has a higher DSPF capacity and faster rated scan speed.

The gauges above represent Excellent (9–10), Very Good (7–8.5), Good (4–6.5), Fair (1.5–3.5) and Poor (0–1).

* In addition, when a user hovers their mouse over each ghosted out selection, a message that details exactly what needs to be done in order to allow these functions to be selectable appears.

Conveniently, the Favorites tab is the main tab of the driver. This tab includes seven preprogrammed one-touch selections for commonly used combinations of features including last used setting, to allow for the setting of the last job programmed to run again; normal; eco preview; double sided; 2-1 printing; booklet; and secure print. At any time, from any of the tabs in the driver, users can add a favorite based on currently selected functions. Each favorite added can be named, a description can be added, and an icon can be created to represent it. Each user can have his or her own favorites. While this is convenient, BLI technicians would prefer if the Basic tab was the main tab and if more commonly used features (such as quantity) were available on that tab.

On the right side of most tabs of the print driver are the Paper menu, which provides a list of all currently selected functions, and the Device menu, which includes a device graphic for point-and-click paper selection.



BUYERS LAB

The Paper menu, which is the default menu, provides a list of all currently selected functions. Conveniently, the menu enables on-the-fly job review; users can easily eliminate selections by pressing the “X” box. Users must navigate to the Device menu to locate the device graphic; unlike with many competitive models, BLI technicians found that the device graphic perfectly represented the device’s settings.

EASE OF USE—SCAN

• Supports a wide range of file types

• Simple scanning from the desktop with Easy Document Creator, which lets users view scanned im-ages before sending them, convert files to e-Book format and send faxes

• Scan preview is oddly named “Play” and is easy to overlook, and users must press an additional icon, which is also easy to overlook, to view full-screen preview

• Unintuitive process for selecting destinations via LDAP at the control panel; users cannot select more than one LDAP destination at a time on the fly

• Job build function is difficult to find and very limited in functionality

Overall, the Scan and Send interface was found to be easy to use. A pull-down menu clearly identifies each function on the screen, and users simply tap on each choice to pull up the options. “Virtual” hard keys supported from the Scan and Send interface include reset, stop current operation and start job.

Scan preview mode can easily go unnoticed by an operator, as it is oddly named “Play.” BLI technicians noted a bit of a delay when many pages were being scanned. In order to view a full-screen preview of the pages, users must click on a square icon that appears on the lower right corner next to the thumbnail, which is also easy to overlook. BLI technicians would much prefer to not have to press an additional key for full-screen preview and for this to be automatic.

Though jobs can’t be auto-split by file size, they can be split by number of pages; for example, if ten documents are loaded into the document feeder and the user chooses to have the pages split into single documents, each document will be scanned as a separate file.

The scan to USB function is located in the same menu as Scan and Send, unlike with some competitors who have separate interfaces for scan and scan to USB functions. As with regular scan mode, although jobs cannot be auto-split by file size, they can be split by number of pages and preview mode is easy to overlook.

search LDAP addresses at the control panel, users must tap the contacts icon next to the address box, select the address book, select Server, and then select the text box before typing in the name to be searched. This multistep process is confusing to users.

And unlike with most other systems, users cannot select more than one LDAP destination at a time on the fly; this results in a more than average number of keystrokes required to scan to multiple destinations (20 to two destinations), whereas most other systems require only one additional button press for each additional destination.

The device’s 10.1" Android-based control panel is made up entirely of touch-keys, with no hard keys.

Users interact with the device in much the same way they would when using a smartphone or tablet; tap to select menus, tap and hold apps and widgets at the control panel to move them or delete them, and swipe to scroll through menus and screens. Users unfamiliar with an Android-based system might find the control panel confusing to work with initially.

The control panel can be tilted up and down freely. “Virtual” hard keys are available for Reset, Interrupt, Start and Stop. Icons allow users to go to the Home screen, or go back to the last page they were working in. The display also features an icon that takes users to a history page in which recently visited pages and functions can be scrolled through and selected. A Help touch key is available and although the help provided is not dynamic in that it doesn’t relate to the currently selected feature, it does provide a very detailed guideline to all of the device’s functions and capabilities.

While users can easily wake the device by touching the interface or placing a document in the document feeder, if a document is inadvertently left in the document feeder from a previous user and a second user wakes up the machine, it will automatically make a copy if users press in the area of the start key or quick copy key.

* However, as with adjusting brightness, users must select the time in the top right corner of the screen and pull down to view toner status; this is not intuitive as most walk-up users would not think to do this.

Toner status can also be viewed in the Settings menu by navigating to Supplies Life, or in the Apps menu, which is accessible from the Home screen. A device graphic on Home screen indicates the amount of paper in the drawers in 25% increments.

Three different copy interfaces are available: a one-touch copy button, Quick Copy menu and Copy menu, and users can switch between any of the three with ease. The one-touch copy button allows users to change only quantity before the job is output. This is useful for environments in which most copy jobs do not require any additional settings, allowing users to copy their jobs quickly.

The Quick Copy interface was found to be highly intuitive, as it offers one-touch buttons for the most commonly used features used for copy jobs.



BUYERS LAB

BuyersLab.com14

The Copy interface offers the same basic capabilities of the Quick Copy interface, along with more advanced capabilities, including poster mode, image repeat, watermark, stamp, overlay, erase edge, image shift, image adjustment, background adjustment, mirror image and covers.

Both the Quick Copy and Copy interfaces provide a graphical review of current job settings, as well as a history of most recently selected job settings. In part because of the many features included on it, the Copy interface was found to be a bit busy. Although the labelling of some functions is not consistent with the industry-standard terminology typically used in other brands of copier MFPs, the selections are very easy to understand —for example, rather than 1:1, 1:2 and 2:2, users select one-sided or two-sided for both the original and the output. Administrators can change the order of the keys with the UI Configuration tool, accessible via a dropdown menu from the upper right corner of the Copy screen.

When programming any kind of job (including scan), users can store one-touch programs (settings for frequently jobs) by navigating to a drop-down menu in the upper right corner of the screen they’re in. From the menu, they select “Add to My Programs” and name the program. These programs are accessible from the Programs tab under the Apps menu and can be stored on the Home screen for easy selection.

The Apps menu is also where users would access software solutions compatible with Samsung’s eXtensible Open Architecture (XOA) platform, as well as widgets that allow users to adjust settings and initiate jobs. Personalized customization of the panel is available via the My Page app; here, users can store personal profile information, and well as customized device settings that are available once a user is logged into the device. In addition, a usage menu details how many copy, print fax and send jobs a logged-in user has performed, as well as how close the user is to his or her usage quotas.

While a proof copy touch key is available, the process for selecting it is rather unintuitive. When a quantity greater than one is selected, a proof copy selection appears in the upper left corner of the display. But users must tap on the proof copy selection, then press start, whereas many competing models will run off a proof copy immediately following the selection of a proof copy key.

The icon on the taskbar changes to an orange “X” to indicate error conditions regarding device status, and to a yellow “X” to indicate warning conditions. However, the small icon can be easily overlooked and indicates only that there is a problem, not precise details.

Productivity

PRINT PRODUCTIVITY

• Runs at the highest percentage of its rated speed of competitive models when printing sets in both simplex and duplex modes

• Outstanding productivity when printing booklets; runs faster than its rated speed

• Device warms up as soon as print jobs are programmed (rather than once the job is sent, as with most competitive devices), which can save time

With a rated speed of 40 ppm, the Samsung K7400LX performed competitively with its peers in most print productivity tests. Notably, the device warms up once the user begins to program a job, rather than once a job is sent from the user’s PC, as is the case with most competitive devices. This can be a time-saving convenience, as users can expect the device to be ready to print once they walk up to it.

PCL 34.3 30.9 85.7 79.8

BLI’s job stream includes Word documents, Outlook email messages, Excel spreadsheets, PowerPoint, HTML and Acrobat PDF files, totaling 19 pages. This test simulates the type of traffic a typical device might experience in a real-world, multiuser environment. All files are sent to the device as a group, at which time the stopwatch begins; timing ends when the last page of the last file exits the device. Efficiency is determined by the percentage of the rated speed at which the device operates when producing real-world jobs. The closer the rate is to 100%, or if it exceeds 100%, the more efficient the device.

SCAN PRODUCTIVITY

• Significantly faster than average duplex scan speeds

• Small compressed color file sizes

Scan-intensive environments are sure to appreciate the K7400LX’s fast duplex scan speeds, which are over twice the competitive average. And although there’s no compression offered in black mode, black file size is still smaller than average compared to the default compression of the competitive group and color file sizes, which are more important (as they are much more likely to impede the sending and storing of files), are smaller than average. It should also be noted that, for a higher suggested retail price, Samsung provides the “GX” configuration, which delivers even faster scan speeds thanks to its faster document feeder.

COPY QUALITY

• Dark, fully formed characters in text and consistently distinct fine lines

• Grayscale visible over the entire measured range

• Consistently dark solids

• Average amount of stair-stepping noted in diagonal lines; slight banding evident in grayscale

While not quite as impressive as print quality, overall copy output was still of high quality. The device stood out most for its excellent shading capability, with grayscale visible over the entire measured range, and its dark solids, which can come in handy when producing documents with company logos in monochrome, for example. As with print mode, the device proved more than capable of meeting the image quality needs of typical office environments in copy mode.

The accessibility function was difficult to use overall. As a user slides his or her hands across the interface, a speaker reads off each feature as it’s scrolled over. The screen also vibrates as a user’s hand comes into contact with each selection. However, the sound is somewhat muffled and difficult to make out. Once a function is located, a user must double-tap on the display to select it, but BLI technicians found that locating the precise spot to tap was difficult, requiring a fair amount of trial and error.

Test Procedures

Test Environment: This product was tested in BLI’s environmentally controlled US test lab, which replicates typical office conditions.

Test Equipment: BLI’s dedicated test network, consisting of Windows 2008 and Microsoft Exchange servers, Windows 7 workstations, 10/100/1000BaseTX network switches and CAT6 cabling.

Test Duration: A single product is tested for two months, five weeks of which consists of a durability test during which the product is run at its manufacturer-rated maximum monthly duty cycle, with 25 percent of the test volume comprised of copy jobs and 75 percent comprised of print jobs. BLI’s daily test usage is designed to replicate real-world use over an eight-hour workday, and as such includes a mix of various-size documents, simplex and duplex modes, and a mix of short, moderate and long run lengths, and on/off cycles, throughout the day. The durability evaluation also includes testing of the document feeder/scanner in simplex and duplex modes for an additional 10 percent of the monthly maximum volume, evenly divided over the course of the test.

Tested Configuration: Lab tested the Samsung MultiXpress K7400GX base unit, plus optional booklet finisher, punch unit and high-capacity feeders. Tested scan productivity on the Samsung MultiXpress K7400LX.

Test Procedures: BLI’s lab testing includes both BLI proprietary and industry-standard test procedures and documents. In addition to a visual image quality evaluation, optical density of primary color (CMYK) solid fill output is measured using a densitometer, and color gamut and consistency are evaluated using a color spectrophotometer. The reliability test is conducted using Georgia Pacific and Boise paper in the US, and UPM, Data Copy and Mondi paper in the UK. In both labs, 30 percent of the paper is recycled. The media used for image quality testing is Georgia Pacific Printing Paper (24 lb., 96 brightness) in the US and UPM Future ImageTech 100 gsm in the UK.

Competitive Group: The analysis in this report compares the tested device to a group of all other currently available like models (e.g., color vs. color, copied-based vs. copier-based) in the same speed range (5 ppm up and down from the speed of the tested device) with support for the same media size. For test performance categories, the results are compared with those of currently available tested models in the group, whereas for feature set and pricing, the comparison is made against all currently available models in the group, whether tested or not. The pricing analysis is for devices comparably configured with accessories and the most common options.

Note: This report is based on BLI testing one representative test sample at a specific point in time. BLI is not responsible for differences in performance that may be the result of lot-to-lot variation, changes in production and machine modifications implemented by the manufacturer, service issues or any other reason beyond BLI’s control.
