BUYERS LAB

Test Objective

Buyers Laboratory Inc. (BLI) conducted a comparative test of new Canon toner cartridges against

‘compatible’ toner cartridges manufactured by Katun for use on the Canon iR C2380. All cartridges

were tested for yield and the devices were tested for image quality and reliability using the

respec-tive cartridges. Each cartridge brand was tested on two Canon iR C2380 devices, with each of the

devices run to 200,000 impressions.

Executive Summary

In BLI’s lab evaluation, the two Canon iR C2380s running Canon toner did not experience any

reliability issues over the course of their 200,000-page tests, with all drums exceeding life and

im-age quality remaining stable, with only marginal drop-off in colour gamut size and optical density

as drums reached and exceeded end of life. Each Canon model required only one service call,

which was simply to replace drums that had exceeded their rated yield. Toner yields were

consis-tent with the pattern of slight drop-off as imaging drums approached and exceeded life. Neither

device required a cleanup when the second set of imaging drums were installed at circa 110,000

impressions, with only minor leakage of yellow toner at the front of the unit.

In contrast, the two devices running Katun-compatible toner experienced many problems over

the course of the test, requiring a total of 14 service calls between them. From the start of the test,

both of the devices running Katun toner had an image quality issue—double imaging on

docu-ments with heavy coverage close to the leading edge of the page. For both, this issue occurred

over the first 25% to 30% of the test period, reappearing again on one of the two devices in the

final 25% of the test run. On each occasion the issue was related to a failure of the drums: the

repeat image matched the diameter of the imaging drum and was eliminated upon replacement

of the drum.

A major issue related to toner leakage and contamination of the imaging station with the Katun

toner (especially with cyan and, to a lesser extent, magenta) led to multiple service calls to clean

heavily contaminated laser windows that were causing sub-standard image quality. It is also likely

that the toner leakage issue caused premature failure of the fuser unit on device D at 180,000

im-pressions. It also contributed to poor toner yield. Indeed, the two devices running the Canon OEM

toner cartridges achieved yields that were on average 30% higher for the three color toners and

14.6% higher for black. The difference in the ratio between toner used and waste toner generated

was dramatic, with the Katun toner generating 66% more waste toner than the Canon toner. BLI

suspects that the toner spillage issues are in part due to a higher quantity of toner being drawn

on to the drum during the imaging process from the Katun toner cartridges than from the Canon

cartridges. In turn, more toner needs to be cleared from the drum after transfer to the ITB, putting

excess strain on the waste toner transport system within the drum unit. Similarly, this could also

be the cause of the intermittent double-imaging issue with documents with heavy coverage near

the leading edge--the quantity of toner deposited at the front edge of the drum during the

imag-ing process may be such that the cleanimag-ing blade cannot successfully clear it prior to the second

rotation of the drum.

In summary, the Canon toner outperformed the Katun toner in every aspect of BLI’s test, with

superior yields, better colour stability, superior device reliability and greatly reduced servicing

demands.

toner leakage in waste toner transport area. Engineer thoroughly cleaned and vacuumed device drum assembly, laser assembly, behind ITB and toner transport area due to heavy contamination. Drum was at 118% of advertised life

expectancy.

Notes: Double imaging of solids near leading edge continued to affect image quality up to image quality samples printed at 50,000 impressions. After that time, the issue was not observed.

Service calls to the device required a lengthy cleaning period on most occasions, with the imaging unit, including drums, laser windows and transfer belt, all being heavily contaminated with toner. There was also significant toner contamination/leakage in the waste toner area.

* This service call is classified as an extension of service call at 115,048, as the yellow drum had already exceeded its life at the 115K visit and could therefore have been replaced at the same time as the cyan, magenta and black drums.

replaced at the same time as the yellow and black drums.

159,979 Double-imaging of CMYK solids near leading edge, _{9.5cm to the left of the original image.}

New CMYK drums installed (after only 10,748 impressions). A full auto-gradation procedure was

performed. No cleaning of the drum assembly or toner transport path was required.

Notes: Double imaging of solids near the leading edge continued to affect image quality up to 70,000 impressions, after which the issue was not observed again on image quality samples until 159,979 impressions into the test. Drums were replaced, but the double imaging issue recurred within 10,000 impressions and was observed intermittently until the end of the test.

Service calls to the device required a lengthy cleaning period on most occasions, with the imaging unit, including drums, laser windows and transfer belt, all being heavily contaminated with toner. There was also significant toner contamination/leakage in the waste toner area.

* This service call is classified as an extension of service call at 133,386 as the magenta drum had already exceeded its rated life at the 133K visit and therefore it could have been replaced at the same time as the yellow and black drums.

General Reliability And Servicing Observations

Canon toner devices (Devices A and B)

The two devices running Canon toner experienced no reliability issues over their

200,000-impres-sion test runs, with only one service call per device to replace CMYK drums that had significantly

exceeded their rated life and had therefore begun producing unacceptably degraded image quality.

The imaging stations on both devices were very clean, with only some yellow toner leakage around

the waste toner bottle. Neither device required a cleaning during their mid-test drum replacement.

Katun toner devices (Devices C and D)

Double-Imaging Issue:

Both devices running Katun toner experienced issues with double imaging when there was heavy

coverage close to the leading edge, with a repeat image visible 9.5cm to the left of the original image.

This problem was not present when the Katun toner was first installed in the devices, with the output

produced 500 impressions into the test runs showing no evidence of this issue on either device.

How-ever, at the 5,000-impression image quality evaluation, double imaging could clearly be seen on the

output from both devices. This problem was eliminated when new drums were installed. To determine

how quickly the issue might return, BLI conducted an image quality evaluation after another 2,500

impressions and observed that the repeat image recurred. It should be noted that the issue is specific

to the presence of heavy coverage close to the leading edge of the document. On the ISO24712 test

document, which was used for the yield and general reliability performance of the devices, there was

no evidence of double-imaging. At this point the drums were replaced again and the image quality

defect was again eliminated. Below are a selection of scans that show the results of a test BLI

con-ducted to investigate the relationship between the double-imaging and the location of the original

image. As the images show, the double-imaging issue becomes less prominent as the solid print area

is located further away from the leading edge. BLI continued the test from this point on, having made

the decision to exclude the double-imaging problem as a cause for classifying a drum as end of life

and instead looked for other image quality defects when making the call on end-of-life status. The

double-imaging issue continued to be monitored every 5,000 impressions. It was no longer evident

beyond 50,000 impressions in output produced by device C and in output produced between 70,000

and 159,979 impressions on device D. At 159,979 impressions, output produced by device D again

started showing double-imaging issues, which continued intermittently until the end of the test.

Toner Contamination of the Laser Windows:

Device C suffered from recurring cyan toner spillage, which on several occasions resulted in image

quality degradation due to contamination of the laser window. Contamination was heavier towards

the front of the device, gradually lessening in severity towards the rear of the device. This resulted in

uneven cyan placement on the page and colour inconsistency (see samples below, where the two

green blocks on the ISO test file are supposed to be the same colour but are clearly different due

to irregularities in the CMYK mix). The cyan toner spillages also caused premature failure of cyan

drums.

Illustration of impact of laser window contamination with KATUN toner

Toner Contamination in the Fuser Unit:

Device D experienced issues with toner in the fuser unit, causing marks on printed output. At 11,503

pages into the test, this was observed as a mark at the bottom of printed output. This was

investi-gated and, as the photos below show, it was proven to be caused by a large toner deposit on the

fuser roller. The issue was not present for long on this occasion, with the fuser’s cleaning system

removing the excess toner successfully.

However, at 180,000 impressions black marks were observed on the bottom and reverse side of

printed output, as illustrated in the photos below, and gradually became worse, appearing on every

printed page by the end of the test. Upon close investigation at the end of the test, a built-up deposit

of black toner could be seen behind a fuser roller cleaning blade in a location corresponding to the

location of the black marks on the printed output.

Toner Leakage Issues:

Both devices running the Katun toner were considerably more contaminated with toner than the

devices using Canon toner, requiring multiple clean-ups during the test. A selection of images

high-lighting the differences are provided below.

* Includes waste toner bottles not completely full at end of 200,000 impression print run.

The Canon toner demonstrated a clear yield advantage of 30.3 across the CMY colour toners and

and a 14.6% advantage on the black toner cartridges. With image quality produced by the device

running the Katun toner showing comparable or worse image quality, the toner yield deficit cannot

be justified by the argument that the Katun toner uses more toner on the page, presumably

deliver-ing higher-density printed output; only solid black solids had a significantly higher optical density

with the Katun toner. Neither can the reason be the amount of toner supplied in the Katun toner

cartridges, with the net average weight of toner in the Katun toner cartridges being within 0.5% of

that in the Canon cartridges.

The cause of the toner yield deficiency with the Katun toner would appear to be the much higher

levels of loss/waste of toner during the imaging process, with leakage inside the device causing

im-age quality and servicing issues as discussed earlier, and also into the waste toner bottle, resulting

in lower yields per bottle, raising parts costs. In fact, the amount of waste toner generated on the

devices running Katun toner was substantially higher—66% higher—than that for the two devices

running the Canon toner; the two devices running Katun toner generated a combined 19,191.6g of

waste toner (excluding waste toner in the bottles still inside the devices at the end of the test) versus

a combined total of only 11,515g of toner from the two devices running the Canon toner, which is

7,676.3g less than that wasted on the devices using Katun toner.

The colour gamut size and shape proved to be more consistent with the Canon OEM toner.

Maxi-mum colour gamut size over the 200,000-impression tests was comparable for the Canon and

Katun toners. However, the devices using Katun toner suffered from larger drops in gamut size and

also had a less consistent shape compared to the Canon toner devices.

Peak Delta E 12.8 14.8 21.1 21.6

Mean Delta E 4.5 4.5 7.0 7.6

The output produced by devices running Canon toner displayed superior colour consistency, with

the mean colour drift for both devices at Delta E 4.5, versus the devices running Katun toner, which

both had mean Delta E drifts exceeding 7. Note: Delta E is a measure of how close two colours are

to each other, with a Delta E of zero indicating a perfect match. Delta E of 4 is commonly regarded

as the level at which the typical user can discern a difference between two samples.

In addition to the poorer colour consistency in the output from page to page of devices running

Katun toner, one of the two devices also suffered from a repeating issue of colour inconsistencies

on the same page. This was due to toner spillage inside the device that contaminated the laser

win-dows resulting in inconsistencies in the discharging of the drum.

With certain documents with heavy coverage solids located near the leading edge of the page,

image quality on the output produced by the devices running Katun toner was further affected by

double-imaging. This issue was observed on both devices running the Katun toner as discussed

earlier in the report.

(17)

Test Methodology

BLI ran four new Canon imageRUNNER C2380 for 200,000 impressions, two with

Canon-manufac-tured toner cartridges and two with Katun’s ‘compatible’ toner cartridges. Each device was

oper-ated in default mode, with PCL as the page description language. Toner and waste toner bottle page

yields, cartridge reliability and image quality were evaluated per the following:

ISO/IEC 24712 Test Target

Toner Yield:

Yield was determined by using a five-page test suite as specified in ISO 24712 and

compared. All cartridges were weighed before and after testing to determine net toner weight and

impressions per gram of toner. Each toner cartridge and waste toner bottle was run until the “toner

empty” or “waste toner bottle full’”warning was displayed on the MFP control panel, after which the

cartridge or bottle was removed and weighed, and the page count was recorded. Test results for

the Katun-supplied brand were compared to those for the original Canon brand cartridges. The

“av-erage-pages-printed” was calculated using all cartridges tested (including all “out-of-box” failures

and print quality and reliability failures that occurred). Any cartridge malfunctions, including

“out-of-box” failures, operational failures, toner leakage, drum flaws and background on printed pages, as

well as device malfunctions caused by cartridges (such as fuser damage due to toner caking) were

recorded. (Cartridges classified as “out-of-box” failures are those that either could not be run due to

excessive toner leakage, or broken or missing parts, as well as cartridges that produced only 20 or

fewer acceptable pages in the test).

Hardware Observations:

BLI test technicians photographed any toner spillage, error messages,

dusting, contamination inside the devices, and image quality defects.

(18)

Reliability:

Throughout testing, BLI test technicians recorded any cartridge malfunctions, such as

operational failure, toner leakage and background on printed pages, as well as device malfunctions

caused by cartridges. In the event of excessive toner leakage causing imaging drum failure, the

device was thoroughly vacuumed out and cleaned before new cartridges and imaging drums were

installed.

Image Quality:

When evaluating image quality, BLI test technicians printed BLI proprietary test

charts and a 300-patch ICC profile at the beginning of testing and every 5,000 pages throughout the

test run of 200,000 pages. From these samples optical density, colour drift, colour gamut size and

general image quality were recorded.

Colour gamut size is measured using an EFI ES1000 colour spectrophotometer and the ICC colour

profile CIE gamut size is measured using Chromix ColorThink Pro software.

Colour drift/consistency is measured using a BLI test target with 12 spot colours. Colours on the

test target printout are measured every 5,000 impressions and compared against the same spot

colour patches generated at 500 impressions into the test. The colour drift is measured using an EFI

ES1000 colour spectrophotometer and GretagMacbeth EyeOne Share software.

Solid fill optical density is measured using an XRite 508 densitometer.

Test environment/conditions:

All testing was conducted in a controlled environment at Buyers Lab’s test facility located at 1

Sta-tion Industrial Estate, Wokingham, UK, per the following condiSta-tions:

Temperature was maintained within 20°C and 25°C, with daily conditions monitored and logged

24/7 by a Seven-Day Temperature/Humidity Chart Recorder.

Relative humidity was maintained within 35% and 65%, with daily conditions monitored and logged

24/7 by a Seven-Day Temperature/Humidity Chart Recorder.

Materials conditioning: Printers, paper and cartridges were acclimatized to the above conditions

for a minimum of 24 hours before testing. Prior to acclimatization, packaging and shipping materials

were opened in a manner that prevented light damage from occurring to the print cartridges during

acclimation. Paper was acclimatized in a ream wrapper.

Acquisition of materials, supplies and service:

All testing was conducted in BLI’s environmentally controlled test facility, using BLI test

instrumenta-tion, workstations and network.

BLI procured all Katun and Canon toner cartridges through customary retail suppliers in multiple

batches per brand, consistent with open market purchases. All paper used in yield / reliability

test-ing was Canon Extra 80gsm and image quality analysis was conducted ustest-ing UPM multitech 80gsm

media.

The four Canon imageRUNNER C2380 MFPs were provided by Canon Europe Ltd. The selection of

the two devices to be used for each brand test was made by BLI at random.
