EPSON Stylus PHOTO 2100/2200 5.2.9 Bi-D Adjustment This adjustment is made to correct the print timing for Bi-D (bidirectional) printing. The following shows the Bi-D adjustment check patterns. Revision B C A U T IO N " 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. Figure 5-22. Bi-D Adjustment Check Patterns ADJUSTMENT Adjustments 208
