2.5.3 Print head position adjustment
As a result of inherent product variations in each BJ cartridge or its specific seating
position, inaccurate dot placement may occur, resulting in poor printing. To correct
this, after installing the BJ cartridge, perform the automatic print head position
adjustment, one of the utilities the printer driver package provides. If a computer is
not available, you can perform the print head position adjustment in
Service Mode .
For the procedures, refer to
Part 3: 2.1 Service Mode Operations (Page 3-8)
. Set at least
one sheet of A4 high-resolution paper into the ASF, and carry out the print head
position adjustment from the printer driver's Maintenance sheet.
If normal paper is used to adjust the print head position, the ink may
bleed, preventing accurate determination. Use High-Resolution Paper (HR-
101) or Glossy Photo Paper (GP-301), which provide higher quality
printing.
Also, be sure to perform the adjustment with the paper thickness lever
raised.
