What is the life span of printer ink?
I am sure you have often purchased ink cartridges for your printers. However, they do not always yield the same number of prints, and the number of prints shown on many websites is not the same.
In fact, the number of prints listed on these websites is only a guide, not an exact number. Every printer is different.
Many factors affect the efficiency of a cartridge, but most importantly, the number of pages printed by a cartridge depends on what is being printed. Hence, the question, “How long does a printer’s ink last?” There is no definitive answer to the question, “What is the best way to get the best results?
How many pages can I print with one cartridge?
As mentioned above, since each printer is different, each ink cartridge is also different. In other words, there is no simple answer to this question.
To simplify, suppose you and a friend each have a glass of water. You are not thirsty, but your friend is. How long will your glass of water and his glass of water remain full? Since it is your friend who is thirsty and you are not, your friend can drink much faster. The same goes for printers.
What is a page rendering cycle?
In other words, the page yield or duty cycle is the maximum number of pages that can be printed before the cartridge runs out.
However, things are not that simple.
For years, major manufacturers have used proprietary methods to calculate page yield or duty cycle. This has caused problems. For example, HP has developed a black toner with a yield of 2500 pages/cycle. Brother, on the other hand, has developed an equivalent toner with an efficiency of 3000 pages/cycle The two manufacturers’ toner estimates were very different.
What affects page/cycle efficiency?
Even if a cartridge with a capacity of 2000 pages is purchased with a cartridge usage of 5% per page, if the page in question contains a lot of information or images, it will use more than 5%, which will also affect the estimated capacity (2000 pages). This is because the amount of text, color, images, etc. on a page affects the amount of ink used and ultimately the overall efficiency/cycle (number of pages) of the cartridge.
As for the originals, it is necessary to consider the print coverage of 5%. This means that the number of prints actually available depends on the sheet coverage which is determined with a 5% full coverage on an A4 sheet. So it is easy to understand that the presence of a header with company logos or footer information can significantly increase the real coverage by 5% and therefore decreases in proportion to the number of pages that can be printed.
Many printer models offer an estimate of the remaining print, this represents useful information but must nevertheless be taken with due consideration. This is a calculation related to the prints made, therefore the actual number could increase as well as decrease if the user prints documents different from the previous ones, increasing or decreasing the actual print coverage.
Easily calculate 5% coverage
This standard was established by printer consumable manufacturers to determine the life of toner or cartridge and to compare it with other products or models. It is simply like dividing an A4 sheet into 100 squares and covering 5 completely in color, this gives an idea of what 5% coverage means.
Normally a company that prints documents with a header with logo, text, and info at the foot of the page can reach a coverage of around 15-20%, resulting in a net decrease in the pages that can actually be printed.
Perfect Print in each product sheet indicates the number of pages that the cartridge can always print with reference to 5% coverage as established by the consumable manufacturers. Furthermore, in recent years, various capacity variants of the same product have been introduced in the catalog, with X or XL type abbreviations, which indicate precisely the possibility of purchasing the high-capacity printing version and this often at a truly negligible price difference
Even if one purchases a 2000 page capacity cartridge with a 5% usage per page, if the page contains more information or images, the user will be more than 5% and the estimated capacity (2000 pages) will be affected. This is because the amount of text, color, images, etc. on a page affects the amount of ink used and ultimately the overall efficiency/cycles (number of pages) of the cartridge.
