Apple COLOR STYLEWRITER 2400 - Manual (Page 71)

Ink tanks and cartridges run out of ink too quickly
To extend the life of your ink cartridges, try the following:
m Select Draft print quality in the Print dialog box whenever you can.
m Don’t clean the print head unless necessary.
m Don’t print solid background colors unless necessary.
m Don’t open the printer’s cover unnecessarily. (After you shut the cover, the
printer cleans the print head, which uses up ink.)
m Don’t unplug the printer or otherwise discontinue power frequently.
m Don’t print the test page unless necessary.
