Clearing the TONER LOW Message
If the 16 TONER LOW message appears in the control panel display,
the toner level in the toner cartridge is getting low. The print
becomes lighter and white streaks may appear. (This message
means that it is time to replace the toner cartridge).
If the control panel Config Menu Toner Low item is set to TONER
LOW=ON (or CONT on the LJ4+ and LJ5 printers), the printer
continues to print with the 16 TONER LOW message in the control
panel display. TONER LOW=ON is the default setting.
A Configuration Menu setting TONER LOW=OFF (or STOP on the
LJ4+ and LJ 5 printers) is available that causes the printer to go
off-line and to stop printing when low toner is detected. If TONER
LOW=OFF (or STOP) is selected from the Configuration Menu, you
must press [Continue] (or Go on the LJ 5) to resume printing. Use
the TONER LOW=OFF (STOP) setting when sharing the printer with
other users, or when using MICR cartridges.
You can improve the print quality temporarily by redistributing
the toner as follows:
1 Remove the toner cartridge.
2 Rotate the toner cartridge about its horizontal axis (i.e., not
end over end) to redistribute toner.
3 Reinsert the toner cartridge and press [On Line] (or Go on the
LJ5).
The 16 TONER LOW message still may appear, but the print
quality should improve. If the print remains light, replace the
toner cartridge immediately. Install the new cartridge as
described in the instructions included with the cartridge.
