Adjustment Self-diagnostic Function 220
5.2 Self-diagnostic Function
5.2.1 Overview
Self-diagnosis is chiefly intended to determine the parameters for mechanism
adjustment and firm adjustment.
This function is incorporated in the printer firmware. It is enabled when the power to
the printer is turned on while pressing the specific panel keys.
NOTE: The printer can not be shifted from the normal mode to the self-
diagnostic mode.
5.2.1.1 How to Start Self-diagnostic Function
The key operation to start the self-diagnostic function is as follows:
1. Power is off.
2. Press “ Paper Feed
∆
” + “ Paper Feed
∇
” + “Cut / Eject”.
3. Turn the power on.
4. The self-diagnostic menu is displayed.
5. Turn the power off to close the self-diagnostic function.

„
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.)
