PERFORMANCE SUMMARY

Geared toward small workgroups, the Dell 2335dn Multifunction Laser Printer proved to be a very good overall performer during its lab evaluation. The A4 laser desktop device, which has a rated speed of 33 ppm and offers network print and scan, copy and PC and walkup fax functionality all as standard, demonstrated ﬂawless reliability throughout its 17,500-impression durability test. Easy to set up and use, the 2335dn Multifunction Laser Printer is also productive, as evidenced by its above average job stream productivity using the PCL driver, as well as the fastest ﬁrst-print times for several ﬁles, compared to competitors. The company has dramatically improved feedback to workstations from the previous version of Status Monitor Console by providing more detailed information in the utility and the types of alerts that users can conﬁgure. Additionally, the unit has very good multitasking capabilities and offers automatic duplexing as standard and an above average tested toner yield that exceeded the rated yield. Based on these ﬁndings, BLI highly recommends the 2335dn Multifunction Laser Printer for small workgroups with monthly volumes of up to 5,000 impressions.

Test duration:

Two months, including a 17,500-impression durability test.

Maximum monthly duty cycle:

35,000 impressions.

Manufacturer’s recommended monthly volume:

500 to 5,000 impressions.

BLI’s recommended monthly volume for optimum performance: Up to 5,000 impressions.

More information on the Dell 2335dn Multifunction Laser Printer is available through bliQ (www.buyerslab.com/bliQ).

VERY GOOD

 Physical setup is simple as the 2335dn Multifunction Laser Printer ships fully assem-

bled save for stacking it on top of the optional paper drawers, but note that Dell recommends at least two people lift the unit out of the box and place it in the desired location due to weight concerns. Users then remove the packing tape and open the side cover to access the pre-loaded print cartridges.

 The CD launches upon insertion in the drive, and the automated installation routine

will have users up and running in a matter of minutes. It takes six clicks to install the PCL and Adobe PostScript drivers, as well as included software, using the default routine; the port is automatically created, and the IP address is assigned using DHCP. Furthermore, the drivers automatically detect conﬁgured accessories.

 Dell provides a utility whereby administrators can remotely install the drivers on

workstations for uniform operation across the organization.

Lab Test Report

 The PCL driver is graphical and provides most of the selections for a typical job on



the main screen. So too is the Adobe PostScript driver, which is atypical of this variety in that it’s usually text-based. Still, the fact they’re virtually identical helps boost ease of use in those environments that frequently switch between them.

 The drivers, which have a good overall feature set compared to A4 laser/LED mono-

chrome printers in this speed range and class, both include booklet and N-up—1 to 16—printing. The PCL driver also has overlays, quantity selection up to 999, reduction and enlargement from 25 to 400 percent and the abilities to save settings for frequently used jobs and add watermarks, while the Adobe PostScript driver has quantity selection up to 9,999 and reduction and enlargement from 1 to 1,000 percent.

 Although there’s a collate selection in the Adobe PostScript driver, it didn’t function

in testing; collate must be selected from the print screen within the application for output to be collated. This isn’t uncommon, as most are written to allow the application settings to override the driver’s.



 

 File size increased from one set printed using a 10-page document when producing

multiple collated sets with collate selected from the print screen within the application, but the number of pages sent to the unit didn’t increase, both of which are typical of devices in this class.

APPLICATIONS COMPATIBILITY

compatibility tests. Units are tested for compatibility on Windows XP platforms with Microsoft Word 2000, PowerPoint 2000 and Excel 2000, as well as Adobe PageMaker 7.0, Photoshop 6.0 and Acrobat 6.0, using 25 application test ﬁles that contain text, graphics, halftone images, tables, etc., enabling BLI technicians to evaluate memory usage, ﬁle processing, font rendering and greyscale capability.

up, down, right and left arrows—and a numeric keypad. Users can select a speciﬁc function by highlighting it on the four-line, menu-driven display, then programming the features for that particular job, but if they want to make a copy using the default settings they can simply press Start.

 The unit is easy to use from the desktop via the well-laid-out drivers.

 Adjusting drawers for different size media is straightforward. Although there’s a

spring-loaded ramp, it locks down to allow users to add paper. Users simply press down on the blue tab for the length guide and slide it accordingly; the tab doesn’t have to be removed and reinserted. Furthermore, the side guides move in sync and can easily be adjusted for paper that’s narrower in width. As with most devices in this class, users must conﬁrm the paper size via the control panel.

 Removing misfeeds from any of the four access locations is easy; a misfeed code

displayed on the control panel indicates the jam location (users may need to refer to the user’s guide for the exact location), but users aren’t prompted or instructed how to clear them. The imaging drum might have to be removed to access a misfeed in that part of the unit.

 Replacing the print cartridge is clean and straightforward: users simply open the

front door, pull out the old cartridge and insert the new one.



SUPPORTING TEST DATA

Test Environment

This product was tested in BLI’s 929-square-metre test lab, in an environment monitored by a Honeywell Temp/RH chart recorder, which replicates typical ofﬁce conditions.

Test Equipment

BLI’s dedicated test network, consisting of Windows 2000 and Microsoft Exchange servers, Windows XP workstations, 10BaseT/ 100BaseTX network switches and CAT5 cabling.

Test Duration

Products are tested for two months, a portion of which consists of a durability test during which the product is run at half of its manufacturer-rated maximum monthly volume, with varying daily test volumes designed to replicate real-world use over an eight-hour workday. This variable schedule 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.

Tested Conﬁguration

The Dell 2335dn Multifunctional Laser Printer base model.

Test Procedures

The test methods and procedures employed by BLI in its lab testing include BLI’s proprietary procedures and industry-standard test procedures, which include a BLI-developed variation of ASTM’s 1318-90 Test Method for Determination of Productivity using Electrostatic Copy Machines. In addition to a number of proprietary test documents, BLI uses an industry-standard KATUN test original for evaluating black image quality and test suites from Quality Logic to evaluate applications compatibility. In addition to a visual observation under a Graphiclite D5000 Standard Viewer, colour print quality is tested using a colour test target, which is read using the X-Rite Eye-One/iO Colour Spectrophotometer, and samples are analysed using the CIE XY Chromaticity Diagram. In addition, density of black and colour output is measured using an X-Rite 500 Series Densitometer. Georgia-Paciﬁc Spectrum Multi-Use Paper is used in the tests, 10 percent of which is recycled paper containing 30 percent post-consumer content. Image quality is tested using Georgia-Paciﬁc Printing Paper.

Status Monitor Console (SMC) is either resident or activated manually, displaying information for devices that have bi-directional support enabled. Administrators and users can proactively check SMC for status, names of print jobs, level of toner, guidance for reordering toner when necessary and the user’s manual for troubleshooting details.

SMC is installed simultaneously with the driver and allows for pop-up messages or icon alerts, which notify users of errors and warnings, to be conﬁgured. When a job is sent, the utility pops up so that users can see paper status—“Okay” or “Add Paper”—and remaining toner, as indicated in a percent gauge. Users can enable the pop-ups to appear during printing or disable the functionality altogether. It can also be proactively accessed.

The Printer Settings Report tab includes the Printer Information, Menu Settings, Reports, Network Settings, and TCP/IP Settings pages. The Printer Information page displays device information including the service tag number, printer serial number, printer type (colour or monochrome), asset tag number, memory capacity, processor speed, ﬁrmware version and print speed. The Menu Settings Page provides information on System Settings (time before the unit goes into power-saver mode; whether audible alerts are turned on for errors, print job completion or when the device is out of paper or toner; control panel language; and tray substitution for when the required paper size is not available); Paper Density (plain paper or labels); Auto Registration Adjustment; Altitude Adjustment; Non-Dell Toner; and Tray Settings (displays settings for paper size and type for each tray—including custom sizes—and whether a pop-up menu to set the paper size and type when paper is loaded is displayed at the control panel). The Reports page allows printing of printer settings, control panel settings, job history list, error history, and meter count, as well as a test page. TCP/IP Settings displays the IP Address, Subnet Mask and Gateway Address. The Printer Maintenance Tab allows users to change conﬁguration settings for all of the settings displayed on the Menu Settings page.

Embedded Web page:

The embedded Web page, Dell Web Printer Conﬁguration Tool, lets administrators conﬁgure the unit remotely on the network and monitor paper status—“Okay” or “Add Paper”—and remaining toner, as indicated in a percent gauge.

Consumables monitoring:

Yes, via SMC or the embedded Web page.

Job Stream Evaluation

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

Job Stream in Black Mode:

The unit completed the job stream using the Adobe PostScript driver in 2 minutes

2.44 seconds, running at 9.3 ppm, which translates to an efﬁciency rate of 26.6%.

The unit completed the job stream using the PCL driver in 41.53 seconds, running at

27.5 ppm, which translates to an efﬁciency rate of 83.2%.

Problems encountered:

The unit paused between jobs using the Adobe PostScript driver.
