Hi @Lft1,
Welcome to the HP Support Community
I'd like to help!
I understand you are getting an error on your Color Laser MFP 178nw printer.
Kindly follow the below steps to resolve the issue:
Step 1: Perform a power reset on the printer.
- Turn the printer on, if it is not already on.
- Wait until the printer is idle and silent before you continue.
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Unplug the power cord from the wall outlet.
- Wait at least 60 seconds.
- Plug the power cord back into the wall outlet.
NOTE: HP Recommends connecting the printer power cord directly to the wall outlet - Reconnect the power cord to the rear of the printer.
- Turn on the printer, if it does not automatically turn on.
- Wait until the printer is idle and silent before you proceed.
Step 2: Check for packing materials and paper
Check the toner cartridge and printer for any packing materials and paper that might be causing the error message.
Turn off the printer.
Disconnect the power cord from the printer.

Reconnect the power cord, and then turn on the printer.
If checking for and removing packing materials and paper did not resolve the issue, continue to the next step.
Step 2: Clean the electric contacts on the toner cartridge
The toner cartridge might have a faulty connection to the printer. Use a lint-free cloth to clean the toner cartridge contact (E-label).
Open the toner cartridge access door.
Remove the toner cartridge from its slot.
Use a lint-free cloth to wipe the toner cartridge contact (E-label) on the top left of the toner cartridge.
NOTE:
Coffee filters work well.
