Media Used Sections
îš„ Total media used in the Printer.
îš„ Media used for each media type.
It is possible that the sum of the media used for each media type is lower
that the total amount of media used in the Printer. This is because only the
total media used in the Printer is saved in the backup EEROM which is
located in the ISS PCA. When the Hard Disk Drive is replaced, the total
media used per media type is reset to zero (0), but the total media used is
recovered from the backup EEROM.
Printhead Section
The Printheads currently being used are not counted.
îš„ Total Insertions: This is linked with the crane of the Ink Supply Tubes.
When the Ink Supply Tubes are replaced, the total insertions amount will
be reset to zero (0).
Cartridge Section
The Ink Cartridges currently being used are not counted.
îš„ This section is split by product name and number for each color as we
have different Ink Cartridge sizes. The sample below does not represent
the reality as we only have one size of Black Ink Cartridge (400cc).
Preventive Maintenance Section
Once the value reaches 100%, the corresponding Preventive Maintenance
Kit should be used. For further details, refer to Chapter 9 - Preventive
Maintenance.
