5.2 Self-diagnostic Function

CAUTION „ With this function, all the processing except for some items are executed on the assumption that roll paper is used. Take care,

since even sheets, if loaded, are handled as roll paper.

„ During execution of this function, detection of remaining volume in ink cartridges and Maintenance Tank is not performed. Therefore, when you execute this function for print head replacement or any other work which requires consumption or discharge of a large volume of ink, check the remaining volume in ink cartridges and Maintenance Tank beforehand. (If you neglect this checking, the capacity of the Maintenance Tank can be exceeded so that ink may flow out; never forget to perform this checking.)
