Expired inks be used in inkjet printers?

Expired inks be used in inkjet printers?

In daily work, customers often encounter problems with the ink and solvent of the printer. For example,  ink can be expire? Can it be used printer after it expires? Two models of ink can be use for printer interchangeably? etc...Today we will come to answer such questions in a unified manner. 

1.Will the ink and solvent expire?

The case is affirmative and will expire! Different inks usually have a shelf life of 6 to 15 months, and the solvent shelf life is usually 18 months or more.


2.The ink solvent has expired, can it still be used?
Do not use inks and solvents that have exceeded their shelf life.
CYCJET ink solvents are tested thousands of times during the development process, including their optimal shelf life, to demonstrate optimal print treatment and consistent performance of the printer. If the ink solvent exceeds its shelf life, adverse chemical changes may occur, such as:
》The conductivity is reduced, the ink droplets can not fully absorb the power, and the ink is intermittently printed;
》Causing the formation of insoluble impurities, blocking the ink path and nozzle of the printer;
The viscosity of the ink changes, which increases the blockage and stops the printer.

These changes can cause printer reliability problems and can also degrade print quality. Due to the unpredictable nature of these changes and their potential hazards, it can affect the performance of the printer and speed up the aging of the printer. Therefore, do not use inks and solvents that have exceeded their shelf life. 


3.Can different brands of ink be used interchangeably?
No, please use CYCJET original ink and solvent!

Each brand of ink development and manufacturing is based on its brand"s own printer performance, ink path and other features. If the inks of different brands are mixed, the probability of clogging of the filter and the nozzle will be greatly increased due to the large difference in the composition of the ink components. It will happen that the customer"s product line will not be able to produce normally, increasing the operating costs of their plants and the maintenance costs of the machine.


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

After the printer has been running for a long time, it is necessary to clean the nozzle. During the cleaning process, a container under the nozzle should be kept in place to clean the ink solvent. We usually call it “waste liquid”. 


It is strictly forbidden to discard waste liquid into the sewer or ordinary garbage bin because the chemical components in the ink solvent will pollute the living environment, and some may even affect the health of the body. Therefore, a professionally qualified chemical recycling company is required to carry out waste liquid recovery and treatment.
