ADJUSTMENT
"
When starting Bi-D adjustment, always place the Release lever
in the normal position.
"
Since setting the Release lever in the envelope (PG large)
position automatically selects the Ui-D printing mode, the
adjustment values will not be saved into the EEPROM if Bi-D
adjustment is performed. If Bi-D is not adjusted properly, the
graininess of the image will reduce. Therefore, start adjustment
after making sure that the Release lever is in the normal
position.
1. Select Bi-D adjustment in the adjustment program.
2. Print the Bi-D adjustment check patterns, choose the pattern that has the smallest
displacements in each variable dot, and enter it in the adjustment program.
3. Print the check patterns again, and check the adjustment result.
