If a toner cartridge is empty, replace it with a new, genuine HP toner cartridge.
Consider having a replacement cartridge available to install when the toner runs low. The printer indicates the toner cartridge level is low or very low in the following ways:
The Cartridge light blinks.
A Cartridge is Very Low message displays on the HP Smart App or Windows 7 driver.
Print quality degrades and becomes unacceptable.
If the toner cartridge is critically low or empty, replace it.
