HP ENVY 4501 e-All-in-One Printer - Manual (Page 51)

Use single-cartridge mode
Use the single-cartridge mode to operate the HP ENVY 4500 series with only one ink cartridge. The
single-cartridge mode is initiated when an ink cartridge is removed from the ink cartridge carriage.
NOTE: When the HP ENVY 4500 series operates in single-cartridge mode, a message is displayed
on the printer display. If the message is displayed and two ink cartridges are installed in the printer,
verify that the protective piece of plastic tape has been removed from each ink cartridge. When
plastic tape covers the ink cartridge contacts, the printer cannot detect that the ink cartridge is
installed.
Exit single-cartridge mode
● Install both the black and tri-color cartridges in the HP ENVY 4500 series to exit single-cartridge
mode.
