Cleaning the magnetic encoder
The magnetic encoder head requires regular maintenance in order to ensure the integrity of the data encoded onto cards.
Cleaning of the magnetic encoder is carried out when the printer runs an advanced cleaning cycle with pre-soaked “T” cards (see the “Maintenance” chapter
of this manual for further information).
Repeatedly running the cleaning card through the printer cleans the card feed rollers, the cleaning rollers, the print head and the magnetic encoder read-write
head.
If, in between two routine printer cleaning sessions, the read-write process fails with more than one card, it is advisable to run a printer cleaning
sequence manually (please see the “Maintenance” chapter of this manual for the procedure to follow).
