Printing in the
forward direction
Printing in the
backward direction
2. Check the Bi Direction checkbox to activate the bidirectional printing.
3. Perform printing so as the printing with the first pass and the second pass is almost overlapped.
To make the media feed amount close to "0", adjust the value for the Feed Compensation.
* As a rough indication, a setting around "-5000" (Around "-0000" in the case of 8-head model printers)
makes the media feed amount close to "0".
Make an adjustment of the value where appropriate.
4. Print the file "5_BiD_123_12HEAD.group" ("4_BiD_12_8HEAD.group").
5. Check the results of printing, select where the printed lines are aligned most closely as one line, and input
the compensation value indicated with the line.
6. Feed the paper manually more than around 6 cm.
Refer to "*.*.**" for details.
7. Perform printing again to confirm that the printing of lines of each color is aligned in one line where ±0 is
indicated.
If the adjusted condition is not what is intended, repeat steps from  to 7.
