This self-diagnostic routine is used when the internal test patterns of the PU are printed. Other test patterns are stored in the controller.
1. Go to the self-diagnosis (level 1) mode, and hold the (1) and (5) keys down until "TEST PRINT" comes into view in the upper display (the (1) key is for test item
increment and the (5) key for test item decrement).
2. On the lower display, setting items applicable only to the test printing appear. Hold the (2) and (6) keys down until a target item is displayed (the (2) key is for
item increment and the (6) key for item decrement). When the setting for the item is not required (left at its default), go to step 5.
3. With the press of the (3), (7), the setting item and its setting are displayed on the upper and lower parts, respectively.
Pressing the (3) key increments a setting. Pressing the (7) key decrements a setting. (The last displayed setting is applied.) Repeat step 3 as necessary.
