HP LaserJet Pro MFP 4301, 4302, 4303 - A "Cartridge is low" or "Cartridge is very low" message displays on the printer control panel

Understand the cartridge-related messages on the control panel and what actions to take.

Cartridge is low : The printer indicates when a toner cartridge level is low. Actual toner cartridge life remaining may vary. Consider having a replacement available to install when print quality is no longer acceptable. The toner cartridge does not need to be replaced now.

Continue printing with the current cartridge until redistributing the toner no longer yields acceptable print quality. To redistribute the toner, remove the toner cartridge from the printer and gently rock the cartridge back and forth end to end. Reinsert the toner cartridge into the printer and close the cover.

Cartridge is very low : The printer indicates when the toner cartridge level is very low. Actual toner cartridge life remaining may vary. To extend the life of the toner, gently rock the cartridges back and forth end to end. Consider having a replacement available to install when print quality is no longer acceptable. The toner cartridge does not need to be replaced now unless the print quality is no longer acceptable.

Rock cartridge back and forth

HP's Premium Protection Warranty expires when a message indicating that HP's Premium Protection Warranty on this supply has ended appears on the Supplies Status Page or the EWS.

Change the “Very Low” settings

You can change the way the printer reacts when supplies reach the Very Low state. You do not have to re-establish these settings when you install a new toner cartridge.

Change the "Very Low" settings from the control panel

Determine how the printer will notify you about very low cartridge levels.

From the Home screen on the printer control panel, touch the Menu icon, and then touch Settings.
Scroll to and touch the following menus:
1. Supplies
2. Very Low Behavior
3. Black Cartridge or Color Cartridge
Select one of the following options:
- Select the Stop option to set the printer to stop printing until you replace the toner cartridge.
- Select the Prompt to Continue option to set the printer to stop printing and prompt you to replace the toner cartridge. You can acknowledge the prompt and continue printing.
- Select the Continue option to set the printer to alert you that the toner cartridge is very low, but to continue printing.
- (For Color Cartridges) Select the Print Black option to set the printer to alert you that the toner cartridge is very low, but to continue printing using black only.
Note:
The Low Threshold option allows you to define the level of ink that is considered very low.

For printers with fax capability

When the printer is set to the Stop or Prompt option, there is some risk that faxes will not print when the printer resumes printing. This can occur if the printer has received more faxes than the memory can hold while the printer is waiting.

The printer can print faxes without interruption when it passes the Very Low threshold if you select the Continue option for the toner cartridge, but print quality might degrade.
