m251nw poor print quality issue

[oxox]

I am suddenly experiencing print quality issue.
It started to happen today.

Please see below photos I've attached ( I've also attached the diagnostic page, supplies status, print quality test)

I've done "hard reset" my printer + "HP LaserJet Pro 200 Color M251n and M251nw - Troubleshooting Print Quality Issues",
but could  NOT resolve the issue.

I don't recall changing anything...(same papers, same print options...) 
I tried to print using different computer, but issue still happens.
Nothing was found on cartridge + drums neither

This is really frustrating..

Thank you in advance for your help

Here is my printer info:

Model:   HP Laserjet pro 200 color M251NW.

Product No:  CF147A

@oxox,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you're having print quality issues while printing from your HP LaserJet Printer. Don't worry we'll work together to help you find a solution.

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

Have you recently made any changes before the issue started?

What happens when you try to print the print quality page?

Have you tried to print the supplies test pages or print the cleaning page on the printer

Have you tried to inspect the toner cartridge for damage?

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

Let's start off by updating the printer firmware. If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Click here to download and install the latest firmware. Once done, restart the computer.

For more details on how to update, please use this link: HP LaserJet - Update the firmware

If the issue persists, I would suggest here is to do 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.

If you are facing any issue while using the printer then try using HP Print and Scan Doctor (PSDR). PSDR is an automated tool which can diagnose and resolve printing and scanning problems. Please go to this link: HP Printers - Using HP Print and Scan Doctor (Windows)  to download and run HP PSDR. Once you open the program, select your printer and click on “Fix Printing” to automatically diagnose and fix the issue.

If the issue persists, I would suggest here is to follow the steps suggested in the support document for - HP LaserJet Pro 200 Color M251n and M251nw - Troubleshooting Print Quality Issues

Could you please respond to this post with the details and with the results of the troubleshooting as this will help me in further assisting you.

Eagerly waiting for your response!
