Apple Color StyleWriter Pro - Manual (Page 61)

Unwanted horizontal white lines or stripes appear
If white lines appear on the page, check to make sure that all the nozzles are
working by following these steps:
1 Turn off the printer.
2 Make sure you’ve loaded U.S. Letter or A4 paper into the printer.
3 Hold down the power button until the error light turns off. When you release the button,
the printer prints a page that includes a nozzle test pattern like this, with one set of lines
for each of the four colors.
4 Inspect the pattern. If all nozzles are working, you will see four horizontal lines between
each pair of vertical lines.
If the nozzle pattern prints correctly but you still have white stripes on your
printed documents, your printer may require repairs.
5 If any of the horizontal lines are missing, try the following:
m Clean the print head. (See “Cleaning the Print Head” in Chapter 4.) Print
the test pattern again.
m If there are still any missing horizontal lines, super clean the print head.
(See “Cleaning the Print Head” in Chapter 4.) Print the test pattern again.
m If there are still any missing horizontal lines, try replacing the print head.
(See “Replacing the Print Head” in Chapter 4.) You can purchase a new
print head from your Apple-authorized service provider.
A missing line (such
as this one) means a
nozzle on the print
head may be
clogged.
