Xerox Document WorkCentre 450c User Manual page 55

The WorkCentre moves the color print head to the
center of the printer so you can access the color ink
cartridges.
Note If the color print head does not move to the
center of the printer, unplug the WorkCentre's power
cord, wait a few seconds, and then reconnect it.
3. Remove the document tray and open the printer cover.
4. With the color print head installed in the printer,
remove the empty ink cartridge from the color print
head by lifting it up and out.
