@Yogie_Atmodjo,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I see from your post that you are having issues with the print quality while printing from your HP LaserJet printer. No worries, I'll be glad to assist you.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes before the issue started?

Have you tried to clean the electric contacts on the toner cartridge?

In the meantime, let's try these steps heer: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Next thing, I would suggest here is to 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).

1. Open the toner cartridge access door.

2. Remove the toner cartridge from its slot.

3. 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.

4. Insert the toner cartridge into its slot, and then close the toner cartridge access door.

If cleaning the E-label did not resolve the issue, continue to the next step.

Once done, I would suggest here is to print the self test page from the printer and check.

If the issue persists, I would suggest here is to follow all the steps suggested in the support document for - Fixing Print Quality Problems for the HP Color LaserJet Pro MFP M176n and M177fw Printer Series
