FAQ on Ink Capacity and Measurement Standard
Q1) Why Nippon-ink solution was not filling to the rim?
A1) Practically no product able to fill to the rim as it need space for tolerance, movement and prevent overflow or split out due to uneven pressure condition especially during transportation.
Q2) Why Nippon-ink solution is less than others?
A2) All Manufacturers base on Standard Capacity that fall within the tolerance limit. Depends on Actual Usage Size, Material, Thickness, Specification, Absorption Power, Density, Manufacturer Tolerance and Concentration of Ink Solution and Ink Formula that vary from each individual manufacturer. Example,
1. Overall Size and Dimension of Cartridge – depends on Tool and Die Maker on it material used, capability, skill, knowledge, limitation and tolerance limit.
2. Cartridge Material, Characteristic and Thickness – affect the actual storage volume, weight and capacity but still fall within the standard requirement..
3. Sponge Size, Dimension, Absorption Power, Elasticity and Characteristic – to hold, control and regulate rate of ink flow. Some less inferior sponge quality might retain more residue ink. This is the reason why Nippon-ink tends to avoid using sponge design.
4. Density and Concentration of Ink Solution – Nippon-ink imported from USA and refine in factory, has own formula and not base on normal standard ink used locally. Example, purchase paint from ICI, DNT or Nippon paint etc, the color code vary as each color code might be quite close but never be the same due to their own mixture and formula.
5. Actual Usage Size and Dimension – Overall Dimension is fix while the actual storage might vary slightly but the total capacity remain the same. Example Drinks bottle varies in size and dimension but the input capacity still remain the same as 1.5 liter. Which manufacturer tends to base on more than 1.5 liter as non-market size.
Refer to A7 Answer below as it proven by calculation.
Q3) How do you measure and compare the result?
A3) All the Original OEM Manufacturers, like HP, Canon, Epson, Lexmark, Brother etc base on output print copies by ISO / IEC FCD 24711 and 24712 Test Suit comparison criteria. Nothing mentioned on Input Capacity, such extra information provided is use as guideline for consumer.
The purpose of ISO Standard of Testing and Measurement is to prevent Manufacturer from playing with figure by adjusting the Coverage Percentage and/or the DPI Setting and/or special cartridge to reflect and claim higher number of copies (rounding upward).
Case Study 1 – Proof by Calculation (Mathematically)
Assume the coverage at 5% with 720 dpi you can print 100 copies in A4 size.
If you print at 100% coverage at 720 dpi you can only print 5 copies in A4 size.
There is a difference of 95 pages but mathematically they are the same.
Case Study 2 – Proof by Calculation (Mathematically)
Assume the coverage at 5% with 720 dpi you can print 100 copies in A4 size.
Currently printing at 360 dpi, 5% coverage, your print copies increase double from 100 to 200 copies. This happen because resolution was reduces by half (720 dpi to 360 dpi) thus number of print increase. Basically you did not gain anything except base on lower quality printout.
Case Study 3 – Proof by Calculation (Mathematically)
Printer resolution set at 720 dpi (standard) while printing documents varies on the coverage that make it difficult to estimate the number of copies unless set same printer using same paper, printing same document but using different ink cartridge to test the total number of print each brand can produce. Ensure a fair play and no bias (Apple to Apple comparison) against any brand, like ISO Measurement and Testing Method and Procedure. Strictly base on output result and performance of individual brand of cartridge. Compare apple with apple and not apple with orange although they both belong to the fruit family but forever they are different.
By changing printer model, resolution and/or paper might affect the result because different printer model consumption of ink varies with different resolution setting and different paper has different absorption power of ink solution. Result in wrong finding and conclusion been derived.
From Epson’s web (Newsroom Archive) dated 16 June 2004, Title: Canon, Epson, HP and Lexmark, support new ISO Standard that helps customers evaluate Printer and Print Cartridge yield. Under URL: http://www.epson.co.jp/e/newsroom/news_2004_06_16.htm
The Technically robust Testing criteria are (Quoted and extracted from the message):
1. Standard Test Document – as per market standard and availability.
2. Number of Cartridge Tested – Minimum 9 cartridges till they stop printing.
3. Sources of Cartridge – directly from the open market availability.
4. Clear, Objective, End-of-Life Criteria – Determine cartridge yield through measurements that established end-of-life criterion.
5. Number of Printers – A minimum of three cartridges is tested on three different printers to avoid bias due to printer variability.
6. Controlled Environment – Printing environment is controlled and consistent because temperature and humidity variation affects yield.
7. Objectivity – because World wide and Industry-wide participation, the testing criteria reflected objectivity in developing a reliable and rigorous standard.
"Consensus – Driven International Standard were form by Canon, Epson, HP and Lexmark, along with other OEMs, are also working with the ISO Cartridge Standard Committee to develop the similar standard for Color Inkjet Cartridges and Printers as well as Color Laser Cartridges and Printers. These stated are expects to be complete in 2005". (Unquote)

From the above ISO Testing and Measurement, nothing was mentioned on it input capacity.
Q4) Why some Residual Ink left behind and cannot be used totally and completely?
A4) The threshold level is set and control by the program written by the Printer Manufacturer. Quoted "Understand from consumer point of view that this is a technological disadvantage but it can be a technological advantage as it helps to protect the print head from been dried as most of the consumer does not replace the cartridge immediately once the printer stop printing. While the Chip set on the cartridge is used to determine the ink level only. The stoppage of printing and to indicate the cartridge is empty is control by the printer software program".

Epson encountered Class Action sued in USA for Ink “Empty” when there are still balance ink inside the cartridge but unable to print. Below message extracted from the web as shown.
Epson Inkjet Settlement Award Delayed – dated on January 21, 2007, By Heidi Turner. Extracted from Lawyers and Settlement.com (Quoted): The appeal came in response to a settlement between consumers and Epson America, Inc. (EAI) involving early shutdown of Epson's ink cartridges. Plaintiffs alleged that Epson Inkjet cartridges were specifically designed to indicate that they are "empty" when in fact ink still remains in the cartridge. When the cartridge indicates that it is empty the printer function is suspended and will not work again until a full cartridge is inserted.
Despite offering credits to its customers, Epson is not required to change its cartridge software and technology to reflect the actual level of ink in the cartridges. Rather, Epson will include a note on its packaging that each cartridge includes an ink safety reserve and will provide literature that explains why ink safety reserves are necessary for ink cartridges.
The lawsuit was filed in California and other state courts claiming Epson committed several offences including breach of contract, breach of implied warranties, unjust enrichment, and fraudulent concealment. Epson America, Inc. denies any wrongdoing but decided to settle the lawsuit to avoid the cost of litigation.
In order to be included in the lawsuit, claimants had to have purchased, leased, or otherwise received Epson Inkjet Printers between April 8, 1999 and May 8, 2006.
Epson is not the only company to come under fire for printers that shut down before the cartridge is actually empty. Other companies include Hewlett Packard (HP), Lexmark, Canon, Dell, and Brother. In 2002, Lexmark faced a class action lawsuit claiming that they forced consumers to use only their ink.
Other problems with inkjet printers include a "killer chip" that prevents re-manufacturers from making compatible cartridges and expiry dates on cartridges requiring that they be replaced even if they have never been used. (Unquote)

From the above explanation, it indicates that it beyond Nippon-ink control and has nothing related to the cartridge issue.
Q5) What assurance and warranty if Users use and purchase Nippon-ink cartridge?
A5) Nippon-ink has Technical Support Backup Service locally with limited Warranty of 12 months from the date of purchase from the respective dealer receipt.
Q6) What happen if User overfill and/or excess ink flow outside the sponge?
A6) Any excess ink outside the sponge might cause smudge and smear during printing because excess ink outside the sponge tend to flow out faster than those inside the sponge. This will continue till excess ink outside the sponge run out. In normal situation the sponge hold 90% to 95% of ink solution. Any excess ink solution shall be separated in another chamber or compartment through a small control and regulated hole.
Currently factory is developing without sponge type of cartridge to replace the old sponge design and to prevent any patent and copyright infringement issue by the respective owners in charge.
Q7) Why did others claim differently and insist theirs is better and can print more?
A7) Two type of explanation – one base on True concept; another "Sales Talk", by playing with words and figure to capture the mindset and behavior of consumers that has limited awareness, product and/or technological knowledge.
As mentioned above, some use Upper Limit Input Capacity to mislead the consumer and play down the sponge retain of unusable residue ink. Let proof it by calculation:
Assume all the Input ink capacity is the same at 16 ml +/- 2 ml. (Upper Limit – 18 ml and Lower Limit – 14 ml).
Assume Nippon-ink (without Sponge) the Input Ink Capacity is 14 ml. (Lower Limit)
Assume other Compatible (with Sponge) the Input Ink Capacity is 18 ml. (Upper Limit)
With Sponge Ink shall retain by 50% as Unusable (Residue) ink – 18 X 50% = 9 ml.
Minimum (at least 30%) Unusable (Residue) ink retain by Sponge – 18 X 30% = 5.4ml.
By Calculation (Sponge Type) - Usable Ink Output – 18 – 9 = 9 ml. (50% residue ink).
By Calculation (Sponge Type) - Usable Ink Output – 18 – 5.4 = 12.6 ml. (30% residue ink).
From the above proven calculation, it indicates that Nippon-ink (without Sponge) even at Lower Limit Ink Capacity (14 ml) is higher than other compatibles (with Sponge) at Upper Limit Ink Capacity claim (12.6 ml for 30% Minimum and 9 ml for 50% Average). Example, drink with ice and without ice, which drink contain more?
To Trick the User by Weight Measurement - Other Compatible (example Pioneertech) claim that Pioneertech’s cartridge is heavier than Nippon-ink’s cartridge. Base on Total Weight of the cartridge the statement is True because of extra Sponge material that the Manufacturer need to input more ink to meet the Output number of copies due to extra ink retain by the Sponge. (Average 50% Minimum 30%). From the above proven calculation, it indicates Nippon-ink Output is more than what Pioneertech Output claim.
Do not be Mislead, Trick, Misrepresent, Confuse and fall into their Sales Tactic (Bull-Shit). For more detail explanation please refer to “Dealers’ Feedback” and “False and Untrue Claim” on Nippon-ink’s Web.
Currently Nippon-ink is the only compatible that have it own patent design (Owe by the Factory) different from the Original and distribute in Superstores in Singapore since 1996. Nippon-ink had participated in the IT Show (March period) and Comex Show (August / September period) at 6 months interval in Suntec City Level 6, Booth Number 6658 (Fix location), Last Row, Right Hand Side Corner Booth from the Main Entrance for the last 10 years till today.
Nippon-ink base on long term business plan and the factory is ISO 9001 Certification with R & D Capability, Factory Management (ISO 9002) and Testing Procedure and Capability (ISO 9003) to provide Total Quality Management (TQM). While Nippon-ink Sales team base on Total Customer Satisfaction (TCS) to service consumers “Value for Money”.
Nippon-ink did encounter “Jealousy Competitors” trying to damage and sabotage Nippon-ink’s reputation through Verbal Rumor Untrue and False Remarks, Comments, Statement and/or Feedback to Consumers and Dealers without substantial proof and/or evidences to support the case. Upon probing and questioning them in more detail those “Suspects” tend to either “Walk Away” or “Keep Silent”. Why?
