Dear customer,
Each ink has its own specific drying speed and drying characteristics, which has an influence on
its periodical maintenance cycle.
To maximise the life-time of all parts which are exposed to ink, it is crucial to carry out some easy
but important maintenance.
The most important maintenance actions are:
Wash away ink remainders from parts which are not (easily) accessible, avoiding that the ink
dries out, possibly causing blockage.
Regularly remove ink remainders from accessible parts.
Hereafter, tailored to each ink type, you will find simple guidelines explaining how you can
maintain excellent print quality and avoid that parts wear untimely.
Overview
When using the VJ-1614 it is important to perform periodic maintenance. This will help you
maintaining excellent output quality and avoid parts to wear untimely. Depending on your current
ink setup, follow the required periodical maintenance scheme.
1) When using Eco ink
