You may need to run the cleaning cycle several times to get a clean 
nozzle check pattern. For effective cleaning, always run a test print or 
nozzle check between cycles. If the lines on the pattern still appear 
broken after several cleaning cycles, contact EPSON for assistance. 
Aligning the Print Head
If banding appears on your prints, or vertical lines are not straight, you need 
to align the print head. You can use the Print Head Alignment utility if you 
have the EPSON printer driver and utilities installed. See page B-25 
(Macintosh) or page C-27 (Windows) for instructions. 
If you don’t have the utilities installed, you can use the control panel. Both 
procedures align the head for all modes and resolutions. Print head 
alignment involves two phases:
First you print a series of alignment or adjustment patterns.
Then you determine which numbered row of patterns (EPSON Stylus 
Pro 9000) or numbered line or box (EPSON Stylus Pro 9500) has the 
best vertical alignment (smallest gaps). You enter the information on the 
control panel to change the print head alignment.
Printing the Alignment Patterns
For the EPSON Stylus Pro 9000, use 13 
×
 19-inch EPSON coated ink jet 
paper (short edge first). You’ll need 4 sheets to complete the alignment 
procedure, which includes 12 patterns of 7 rows each and takes about 15 
minutes.
For the EPSON Stylus Pro 9500, you can use EPSON roll paper. Six 
patterns of 15 lines or boxes are printed, which takes about 10 minutes. The 
patterns are repeated across the width of the paper.
Follow these steps to align the print head using the control panel:
1. Load paper in the printer. 
2. Press the 
SelecType
 button until 
HEAD ALIGNMENT MENU
 is 
displayed. 
3. Press the 
Item
 button. 
PAPER THICK=STD
 appears on the display.
