As the base model in OKI’s MB760/MB770 series, the OKI MB760 ($1,399 list) is a heavy-duty monochrome, laser-class multifunction printer (MFP) to anchor a busy workgroup. Its most compelling feature is its ability to handle unusually large print volumes for an MFP at its price.
Compared with the OKI MB770 , the OKI MB760 has a slightly lower rated speed (49 pages per minute, as opposed to 55 ppm) and a slightly lower maximum monthly duty cycle (250,000 pages, compared with 280,000), and lacks the OKI MB770′s 20-sheet offline stapler. But it sells for $400 less.
Even with the slightly lower duty cycle, the OKI MB760 is a monochrome MFP built for offices with massive print volumes. It has a sufficiently high paper capacity for that role. But to get it to operate at its full speed, and to prevent from having to power up every time you need to use its screen, you’ll need to make one tweak, as by default it is unusually quick to go into Power Saver and Sleep modes.
The MB760 prints, copies, faxes, and scans. It can scan to email, network folder, or USB key (which it can also print from). It supports secure, password-protected printing. It has a 100-sheet reversing automatic document feeder for copying, scanning, or faxing two-sided documents; it scans one side, flips the page over, and scans the other side.
This MFP measures 26.6 by 20.6 by 23.8 inches (HWD), so you’ll want to put it on its own table, and one without any shelves above it as it is very tall. It weighs 106 pounds, so you’ll want to get two other people to help you move it into place. The front panel houses a nine-inch color touch screen, as well as an alphanumeric keypad and physical buttons for quickly switching between functions.
The MB760 has a 630-sheet standard paper capacity, between a 530-sheet main tray and a 100-sheet multipurpose tray. It comes with an auto-duplexer for printing on both sides of a sheet of paper. You can add up to three optional 530-sheet trays and/or a 2,000-sheet feeder, to a maximum of 3,160 sheets.
There are the other models in the MB760/MB770 family. The OKI MB770 ($1,399 list) has a slightly higher rated speed (55 ppm) and maximum monthly duty cycle (280,000 pages) but otherwise is much the same as the MB760. The OKI MB770f adds a 530-sheet second tray with a caster base for a standard (and maximum) paper capacity of 1,160 sheets, and the OKI MB770fx adds a 2,000-sheet feeder for a 2,630-sheet paper capacity.
The MB760 offers USB and Ethernet (including Gigabit Ethernet) connectivity; we tested it on a network with drivers installed on a PC running Windows Vista.
The MB760, like other recent OKI printers and MFPs I’ve tested, is unusually quick to go into Power Saver and Sleep modes (after just 1 minute and 2 minutes of idleness, respectively). After a minute of idleness, the screen goes dark. To restore it, you need to hit the Power button, and it takes upwards of 10 seconds for the screen menu to reappear.
This quickness to go into power-saving modes is an annoyance if you want to work from the screen, and it significantly impacted printing speeds in our testing. For our official testing, we use a printer’s default settings; our testing protocol has built-in intervals between each test, and the printer went into Sleep mode between each test, and awakened when the print command was sent to it.
OKI says that it is set this way to comply with the Energy Star 2.0 standard for imaging devices, which went into effect in January 1. Time to go into Sleep mode is one of many factors used in determining whether a product is Energy Star qualified, although the required time to go into Sleep mode.is considerably longer than the OKI MB760 is set to by default. The time to both Power Saver and Sleep mode can be reset through the printer’s Admin menu for up to 60 minutes.
The MFP’s quickness to go into power-saving modes at default settings negatively impacted its speed in our testing. I timed it on our business applications suite (using QualityLogic’s hardware and software for timing), at an effective 5.5 pages per minute (ppm), matching the speed I’d timed the OKI MB770 at under the same conditions.
I also did some ad-hoc testing of the MB760 while keeping it out of Power Saver/Sleep mode. As such, it turned in a much more respectable 10.3 ppm, just shy of the 10.5-ppm speed at which I’d clocked the faster-rated OKI MB770. Still, it’s a bit slow for its rated speed. The Editors’ Choice Dell B3465dnf Multifunction Laser Printer, rated at 50 pages per minute, tested at a much faster 15 ppm.
Output quality was slightly sub-par, with average text quality, below-par graphics, and photos were just about adequate. The MB770′s text quality should be fine for any internal business use, and most other business needs short of demanding desktop publishing applications that use very small fonts.
Graphics quality is suitable for most in-house use, though not for handouts going to people you’re trying to impress, and you’ll want to take a close look at its copy before distributing it. In several illustrations, the printer did poorly in distinguishing between similar tones, with both darker and lighter areas appearing as one continuous shade. In one figure, text that should have appeared as drop-out type against a dark background was totally lost.
With photos, there was a general loss of detail in dark areas, and dithering in the form of dot patterns. Some images showed traces of banding (a regular pattern of faint striations) The MB760 can print out recognizable photos from Web pages, which is about all you can expect from most monochrome lasers.
Running costs for the OKI MB760, based on OKI’s price and yield figures for toner and image drum, are 1.7 cents per page, a smidge higher than the OKI MB770′s 1.4 cents and the Dell B3465dnf’s 1.5 cents per page.
The Editors’ Choice Dell B3465dnf is priced the same as the OKI MB760, and provides much faster speed and better output quality, particularly for graphics. The OKI is built for heavier-duty printing, and is modestly priced as such. To get the most out of the MB760, you’ll want to lengthen the time before it goes into Power Saver and Sleep modes. Although this will boost the speed, it’s still relatively slow for an MFP at its rated speed. It’s a reasonable choice as a monochrome MFP capable of massive print volumes for offices on a budget.
