Useful Information about Ink

How is ink used for various purposes other than printing?

Ink may be used for purposes other than printing. Ink is not only used for printing, but also for cleaning the print head to maintain the optimal printing quality.

The printer has the function to automatically clean the ink jet nozzles to prevent clogging. In the cleaning procedure, ink is pumped out from the nozzles. Used ink for nozzle cleaning is limited to a small amount.


In addition to cleaning the print head, the printer automatically performs the system cleaning at regular intervals to prevent trouble such as unwanted lines or the complete stopping of ink ejection.

If the remaining ink level is low, the system cleaning may not be performed automatically. Follow the message displayed on the computer screen to replace the deficient ink tank with a new one.

There will be some ink remaining in the ink tank removed for replacement to perform the system cleaning.

 Note

When using the printer for the first time

 When the printer is turned on for the first time, ink is used to ready the printer for printing.

The remaining ink level can be checked from the printer driver after software installation.

Does black-and-white printing use color ink?

Black-and-white printing may use ink other than black ink depending on the type of printing paper or the settings of the printer driver. So, color ink is consumed even when printing in black-and-white.

Check ink status on the computer screen.

Check if ink is running low on the computer screen.

 The printer uses pigment ink. Due to the nature of the pigment ink, the ink on the printed surface may be removed when being rubbed or scratched.
