When to Replace a BJ Cartridge or BJ Tank
How frequently you need to replace a BJ cartridge or tank depends on how you use
your MultiPASS. If you print many graphics, halftones, or grayscales, you will need to
replace them more often than if you print mainly text.
In general, you will need to replace a BJ cartridge in the following situations:
• If you have been using a BJ cartridge for over a year.
• If your printed output is not crisp and clear or has gaps in the characters (missing dots).
• If the BJ tanks have ink in them but your color printouts appear to be missing a color.
In general, you will need to replace a BJ tank in the following situations:
• If you have been using a BJ tank for over six months.
• If your output is blank.
• If your printouts appear to be missing a color.
• If one of the messages below appears in the LCD:
C INK EMPTY
(Cyan BJ tank is empty.)
M INK EMPTY
(Magenta BJ tank is empty.)
Y INK EMPTY
(Yellow BJ tank is empty.)
K INK EMPTY
(Black BJ tank is empty.)
If more than one BJ tank is empty, several letters may appear (e.g.
C Y INK E M P T Y
).
If one or more of the above messages appear in the LCD, replace the BJ cartridge or
tank(s) as described later in this chapter. If no messages appear, refer to the flow
chart on the next page to determine the problem.
