Bidirectional Calibration
Bi-directional calibration is performed to achieve printing accuracy between the “Left to Right” and “Right to
Left” print sweeps. If the bi-direction offset value is correct, the Left to Right test print would align accurately
with the Right to Left test print at “0” position. In case of error in the BI-DIR offset, the Left to Right and Right
to Left print would align at some other point on the scale. To check the BI-DIR calibration, select the Test Print
option available under the ADJUST BI-DIR menu. The Bi-Dir test result is shown in the below figure:

In the above figure, carefully observe the pattern at which position it is correct. The correction value can be
either positive or negative. Enter the exact value in the given field (Refer to Fig 71) and verify the result by
issuing the TEST PRINT command.
Follow these steps to perform bidirectional calibration:
Step 1: Press the MENU button from the Control Panel. The list of sub-menu appears on the screen.
Step 2: Press the Up or Down arrow button and select the ADJUST BI-DIR option, as shown below:

Step 3: Press the Right arrow button to confirm the selection and press the ENTER button to issue the test
printing, as shown below:

The ADJUST BI-DIR screen consists of two setting options viz. SIMPLE SETTING and DETAIL SETTING. Here,
the SIMPLE SETTING option is used. In case, the SIMPLE SETTING option is not effectively resolving the printing
quality, then it is advisable to use the DETAIL SETTING option.
