Can the inkjet printer ink expire?

In daily work, customers often encounter problems with the use of ink and solvents for inkjet printers.
For example, will the ink expire? Can it still be used after the expiration date? Can two types of ink be used alternately? And so on
.

Today we will answer such questions in a unified manner
.

1.
Do inks and solvents expire? The answer is yes, they will expire! Different inks usually have a shelf life of 6 to 15 months, and the solvent shelf life is usually more than 18 months
.

2.
Can the ink solvent still be used after its expiration date? Do not use the ink and solvent that has exceeded the shelf life
.

During the development process of ink solvents, thousands of tests are carried out, including their shelf life, to prove the printing treatment and the stable performance of the printer
.

If the ink solvent exceeds its shelf life, adverse chemical changes will occur, such as: reduced electrical conductivity, ink droplets can not fully absorb electricity, intermittent printing; resulting in the formation of insoluble impurities, blocking the ink path and nozzle of the printer; ink The viscosity of the printer changes, which increases the blockage and causes the printer to stop working
.

 　　These changes can lead to reliability issues in the printer and can also lead to degradation in print quality
.

Due to the unpredictable nature of these changes and their potential hazards, the performance of the printer will be affected and the aging of the printer will be accelerated
.

Therefore, do not use inks and solvents that have passed their shelf life
.

 　　3.
Can inks of different brands be exchanged? No, please use the original ink solvent! The development and manufacture of each brand of ink is based on its own printer performance, ink path and other characteristics
.

If different brands of ink are mixed, the probability of filter and nozzle clogging will be greatly increased due to the huge difference in the composition of the ink composition
.

It will happen that the customer's product line will not be able to produce normally, increasing the operating cost of their factory and the maintenance cost of the machine
.

 　　4.
How to deal with the cleaned ink solvent? It should be handed over to a professionally qualified chemical recycling company
.

 　　After the printer has been running for a long time, the print head needs to be cleaned
.

During the cleaning process, there should be a container under the nozzle to hold the ink solvent, which we usually call "waste liquid"
.

 　　It is strictly forbidden to discard the waste liquid into the sewers or ordinary garbage cans, because the chemical components in the ink solvent will pollute the living environment, and some may even have an impact on physical health
.

Therefore, a professionally qualified chemical recycling company is required for waste liquid recovery and treatment
