HP PageWide Pro 552dw vs. Competitive Laser Models
COMPARATIVE CUSTOM TEST REPORT
Electricity Consumption (TEC) methodology for the comparative energy evaluation. For reliability testing, two
of the HP Officejet Pro models and two each of the competitive models were tested for 150,000 impressions
each. To evaluate consumables and packaging waste, BLI technicians collected and weighed all the spent
cartridges, waste toner containers, imaging units and maintenance items used by one of each model during
the course of the 150,000-impression test, as well as all related packaging for these items.

Executive Summary
Over the course of BLI’s 150,000-impression test, the HP PageWide Pro 552dw demonstrated a considerable advantage over the competitive laser models tested in several of the test categories. Not only did the
HP model generate the least amount of consumables and packaging waste (up to 95.3% less by weight),
but it also consumed significantly less energy than the competitive laser printers tested. In fact, the HP
model consumed 49.5 percent to 71.2 percent less energy than the laser models in BLI’s energy testing.

In terms of overall reliability, the two HP test units experienced fewer total misfeeds than any of the laser
models. However, while the HP models required nothing more than a quick regularly scheduled maintenance visit to replace a roller at end of life, one Ricoh unit experienced two image quality defects related
to defective toner cartridges that were resolved by replacing the cartridges; each of the Brother units also
had a defective cartridge. While the Samsung unit only required scheduled maintenance, it experienced a
total of 10 misfeeds; the Lexmark models didn’t require service but experienced 9 misfeeds during testing.
Based on the results of this test, BLI feels the HP PageWide Pro 552dw delivered the best performance
overall, with vastly better energy efficiency and waste generation, and reliability and image quality that is
on par with or better than that of the laser competitors, making it a strong choice for general office environments.
HP OfficeJet Pro X551: 700,000 Impressions and Still Going Strong
BLI began testing four of the HP OfficeJet Pro X551dw models, the previous-generation model using PageWide inkjet technology, in early 2014, with the initial plan of subjecting the printer to a 75,000-impression test to prove the technology was stable when compared to laser printers. After the initial test, BLI
extended the test, pushing the X551dw to reach the 150,000-impression mark. Testing was again extended
to the 225,000 impressions and when the OfficeJet Pro X551dw reached that milestone testing continued
to 500,000 impressions. At present count, two OfficeJet Pro X551dw models in BLI's lave have produced
750,000 impressions with little more than regularly scheduled maintenance, which is the equivalent of almost 10 and a half years of use under typical conditions mid- to high-volume small workgoups (assumes
the maximum average monthly page volume of 6,000 impressions). The other two models have reached
700,000 impressions, but are in need of scheduled maintenance.
Reliability Test Results
Printer reliability should be a key concern for buyers, since a reliable device helps minimize downtime,
resulting in improved worker productivity. BLI conducted comparative reliability testing on all six of the
test units, with each run for 150,000 impressions over 40 business days, using a variable test schedule to
simulate real-world usage (for instance, varying run lengths, incorporating periods of high and low print
volumes, as well as periods of inactivity).

During these BLI tests, the PageWide Pro 552dw (3 misfeeds over two units) units completed reliability
testing with the fewest misfeeds. The Brother HL-L8350CDW experienced 4 misfeeds over two test units.
However, while the PageWide Pro 552dw models’ routine part replacement (which reached end of life) took
only 20 minutes, the Brother units were down for two hours while service was performed to replace maintenance items. The Samsung units experienced a total of 10 misfeeds over two test units and required one
scheduled maintenance visit to replace the fuser and rollers, which took about an hour. The Ricoh units
experienced a total of 9 misfeeds and required scheduled maintenance during testing (replacement of the
fuser and image transfer unit). The Lexmark models experienced a total of 9 misfeeds, but did not require
anything beyond user maintenance during testing.
However, one Ricoh unit experienced image quality issues that required BLI technicians to replace toner
cartridges that were defective (one had a faulty chip that did not prompt the operator when it was empty
and the other produced excessive toner speckling down the center of pages that could not be cleared with
a calibration procedure). The Brother units also each had a failed toner cartridge during testing.

Exhibit A: Brother HL-L8350CDW Black Streaking (Defective Cartridge)
At 40,423 impressions on Brother Unit D and 46,659 impressions on Brother Unit C (shown above) into testing, a defective black cartridge, which had
just been installed, caused streaking and speckling on output. BLI technicians replaced the black toner cartridge, which resolved the issue. Output
enlarged to show detail.
Exhibit B: Ricoh SP C320DN Black Speckling (Defective Cartridge)
At 58,819 impressions into testing, a defective cartridge, which had just been installed about 150 impressions prior, caused speckling on output. BLI
technicians replaced the black toner cartridge, which resolved the issue. Output enlarged to show detail.

Exhibit C: Ricoh SP C320DN Black Dropout/Fade (Defective Cartridge)
At 73,707 impressions into testing, a defective cartridge resulted in dropout and fade of black output; upon further investigation, technicians found
the cartridge was empty, but the device never indicated it as such and printing was allowed to continue. BLI technicians replaced the black toner
cartridge, which resolved the issue. Output enlarged to show detail.
Consumables and Packaging Waste
Total Consumables and Packaging Waste Generated at 150,000 Impressions
(Based on testing with the ISO 24712 test target)
Packaging and supplies waste can have multiple impacts on businesses, as well as on the environment. For
instance, in enterprise environments, limiting supplies waste can help reduce storage space requirements
and costs, lower shipping expenses, and reduce recycling/disposal expenses, while favorably impacting
the environment. In BLI’s evaluation of consumables waste for one of each model tested, the HP PageWide Pro 552dw not only used the fewest ink cartridges and other supply items to print 150,000 pages,
which means fewer interruptions to change supplies, but also produced the least amount of consumables
and packaging waste over the test—in fact, by as much as 95.3% less by weight. The total weight of all
cartridges and cartridge packaging required to print 150,000 impressions was just 10.3 pounds for the
HP model. Total weights of all user-replaceable consumable items used (toner, drums and waste containers) and associated packaging for the competitive devices ranged from 114.38 pounds for the Lexmark
CS410dn to 216.85 pounds for the Ricoh SP C320DN.

Comparative Energy Consumption Testing
As corporate responsibility to the environment has moved to the forefront in many industries, many companies have adopted and continue to enforce policies to maximize the energy efficiency of systems and devices
within the enterprise, including PCs and printers. Because a printer's energy consumption is a significant part
of the printing cost of a device that not only affects the company’s bottom line, but also its environmental
impact, HP commissioned BLI to conduct a comparative energy-consumption evaluation using test methods
consistent with the ENERGY STAR Typical Electricity Consumption (TEC) method, with the energy consumed
recorded as kilo-Watt hours (kWh). The test measures the energy that is consumed over a specified period,
during which each device prints multiple single-sided sets of a 12-page black document and also spends time
in sleep mode, warm-up mode and ready mode. For the three models comprising this group, typical usage is
assumed as being 288 pages per day. The values that are reported for each device have been calculated to
reflect one week’s worth of electricity consumption. Note that calculations are based on single devices only,
and values would increase as the number of devices deployed in the fleet increases.
• Based on BLI’s testing, it is projected that during a typical week of usage the HP PageWide Pro 552dw will
consume the least amount of energy, at just 0.728 kWh, making it the most energy efficient model of the
group.
• The Samsung ProXpressC2620DW came in second place, consuming 98.2 percent more energy than the HP
model
• The Brother HL-8350CDW consumed 113.6 percent more energy than the HP model.
• The Lexmark CS410dn consumed 180.4 percent more energy than the HP model.
• The least energy efficient model of the group, the Ricoh SP C320DN, consumed 247.7 percent more energy
than the HP model.

Image Quality
Business users want quality, consistent output, and to get the results they expect the first time; if users
have to reprint a page because colors are wrong or quality is lacking, time and resources have been wasted.
BLI evaluated image quality of all the devices using the ISO 24712 test suite on 24-lb. multipurpose paper
with ColorLok technology at 10,000-page intervals throughout testing.
Although the HP and Lexmark models both produced very good overall black and color output, the Lexmark
had a slight advantage, due in part to higher solid density readings and brighter color output (technicians
noted the HP devices’ color output, though very good, was not as vibrant as that produced by the Lexmark
model). Despite some minor overspray and jagged edges typical of ink technology, the HP’s black output
was very good overall and certainly suitable for general office use. The Samsung and the Brother models
provided the next best image quality, followed by the Ricoh model, which received the lowest overall score.
In terms of consistency of output over time, BLI found that the HP model showed less variation in density
readings for all four colors compared to all four laser models tested. Over the course of testing, BLI technicians noted that a visual examination showed that black and color output from the HP model remained very
consistent; black output from the Ricoh model had inconsistent coverage and became even more mottled
and blotchy as testing progressed Technicians also noted pastel shades produced by the Lexmark model
became inaccurate (blue shifted toward cyan).

Appendix B: Test Methodology
Test Environment
Testing was conducted under ambient conditions of 68F to 78F and 45% RH (+/- 10%), monitored daily by an Extech RH520
temperature/humidity digital recorder and Honeywell Model 61 Seven-Day Temperature/Humidity Chart Recorder, in BLI’s test
facility located at 80 Little Falls Road, Fairfield, NJ (U.S.A).
Test Equipment
BLI’s dedicated test network, consisting of Windows 2003 servers, Windows 7 Professional workstations, 10BaseT/100BaseTX
network switches and CAT5 cabling, Yokogawa WT210 power meter, Powerstat voltage regulator and ESP D5143NT Transient
Voltage Surge Supressor.
Test Procedures
For electricity consumption testing, a method similar to and consistent with ENERGY STAR Typical Electricity Consumption (TEC)
principles was used to determine typical weekly energy usage for each device, which is based on printing 288 pages per day, with
the device spending the remainder of the time in idle and sleep modes after printing is completed. The Yokagawa WT210 power
meter was used to measure energy usage during all modes for each device. Reliability testing was performed using GP Spectrum
and/or Boise X9 20-lb. bond and GP 30% recycled paper. Image quality was evaluated on HP ColorLok 96 brightness, 24-lb.
bond. For waste calculation, BLI technicians collected and weighed all packaging and cartridges, drums, waste containers and
maintenance items generated during a 150,000-impression test.
