It was in December 2002, that Office of Fair Trading (OFT) addressed the major manufacturers – Epson, Canon, HP and Lexmark – so that they developed a unified technique for assessing ink consumption, printer toner yield, etc.
Currently, the cost of consumables is several times of the printer, during its lifespan. Moreover, the manufacturers not always fully fill a printer cartridge with toner, so that a customer was quicker to come for the next one.
OFT affords resulted in new technique of assessment developed by International Organization for Standardization (ISO) in cooperation with mentioned above brands. The technique provides for compulsory testing
- under standardized temperature
- on several type of paper
- several units of same printer model
- with several sets of cartridges
ISO suggests that manufacturers use this technique starting from now, despite it’s now approved as a standard so far. However, only HP and Epson have applied the technique, Lexmark is planning to do so at the end of this month. Canon has not yet responded to ISO recommendations and is using its own methods.
