Print cartridge problems
Incorrect print cartridge
The printer can only print when the correct print cartridges are installed. If you receive a
print cartridge error message, one or both of the print cartridges cannot be used in the
printer. A flashing Print Cartridge Status light indicates which print cartridge is incorrect.
To verify that you have the correct print cartridges:
1.
Open the printer cover.
2. Read the selection number on the print cartridge label.
1 Selection number
2 Warranty date
3. Check the list of print cartridges that can be used in the printer.
Open the
HP Printer Utility and then select the Supplies pane.
4. Check the warranty date on the print cartridge.
5. If the print cartridge has the wrong selection number, or if the warranty date has
expired,
install a new print cartridge .
6. Close the printer cover.
If the Print Cartridge Status light stops flashing, then the problem is fixed.
If the Print Cartridge Status light continues to flash, visit HP Technical Support at
