Care and Maintenance of the Print Heads
To ensure optimum printing, the print heads need to be maintained in good condition. There are
two kinds of maintenance: daily maintenance and periodical maintenance.
Daily care maintenance
Normal cleaning
We recommend performing Normal Cleaning every day before the start of operations.
Periodical care and maintenance
Print heads are consumable parts and subject to wear. Depending on frequency of use,
periodical replacement is required.
