Apple Color StyleWriter 2500 - Manual (Page 30)

Checking the print nozzles
The Color StyleWriter 2500 prints by spraying ink onto the paper through
tiny nozzles. Sometimes these small nozzles get clogged after sitting unused
for a long time. To make sure all the nozzles are working, follow these steps:
1 If necessary, turn off the printer.
The green power light should be off.
2 Press and hold down the power button for about 5 seconds, until the yellow error light
goes out.
3 Release the button and wait for the test page to print.
Press the power button.
When the yellow error
light goes out, release
the button.
