Aligning the Print Head
When you perform head position adjustment, errors in the print head adjustment position are corrected and
conditions such as color and line streaking are improved.
If the print results appear uneven because of line shifts or other conditions, adjust the position of the print
head.
On this machine, you can adjust the print head either automatically or manually.
• To adjust the head position automatically, execute print head position adjustment from the operation
panel of the machine.
