Aligning Print Head - Auto head align Aligning the print head allows you to print without shifts in the color registration. There are two ways to align the print head, automatic or manual. First, try adjusting the print head automatically. If the automatic print head aligning does not work or if you wish, you can adjust the print head manually. See "Adjusting the Print Head Manually" on page 44. 1 With the printer on, load a sheet of Letter plain paper in the printer. 2 Align the print head automatically. (1) Press the Menu button. (2) Use the buttons to select Maintenance and then press the OK button. The maintenance menu is displayed. (3) Use the buttons to select Auto head align and then press the OK button. The confirmation screen is displayed. (4) Use the buttons to select Yes and then press the OK button. A pattern is printed and the print head is automatically aligned.
