HP LaserJet 4345 Multifunction Printer series - Manual (Page 182)

When the cartridge is out of toner or drum life
The REPLACE CARTRIDGE message appears in one of these situations:
● When the print cartridge is out of toner. If CARTRIDGE OUT is set to CONTINUE (in
the SYSTEM SETUP submenu of the CONFIGURE DEVICE menu), the MFP continues
printing without interaction until the cartridge reaches the end of drum life. HP does not
guarantee print quality after the REPLACE CARTRIDGE message first appears.
Replace the print cartridge as soon as possible. (See
Ordering parts, accessories, and
supplies .) The REPLACE CARTRIDGE message remains until you replace the print
cartridge. If CARTRIDGE OUT is set to STOP, the MFP stops printing until you replace
the print cartridge or resume printing by configuring the printer to continue: In the
CONFIGURE DEVICE menu, under SYSTEM SETUP, set CARTRIDGE OUT to
CONTINUE.
● When the drum life of the print cartridge is out. You must replace the print cartridge
to continue printing. No override is possible, even if toner remains in the cartridge. (See
Ordering parts, accessories, and supplies .) This situation occurs to protect the MFP.
