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.

EASE OF NETWORK SETUP
Dell 2335dn Multifunction Laser Printer
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.
The CD contains the PCL, Adobe PostScript and scan drivers, a supplies manage-
ment system, Quick Launch Utility, printer settings utility, Dell ScanManager and
network/PC fax software, as well as a user’s manual in PDF format so that it can be
printed.
OpenManage Printer Manager can be downloaded from the company’s Web site.

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.

The control panel has 10 hard keys—Back, Cancel, Start, Enter, Pause, Directory and
VERY GOOD
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.

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

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.

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.
