print quality degraded

[Pupyi]

I owned a HP Color Laser Jet Pro MFP M283cdw. Not long ago, I discovered when I want to print documents in either black and white or color. The color quality was bad. Instead of having a distinctive color black and white, the document has a faded greyscale look. For color printing, it seemed like some colors were missing. I printed a demo page with hot air ballon with only faded blue and yellow color. The outline of the image was in grey as well. 

I checked the ink level most of them are above 50%. I just purchased black ink recently (100%) but still, the quality was still bad. 

I like to know if there are other ways to fix it or troubleshoot it? I tried to clean it many times but not working at all. Let me know if anyone has a good suggestion. Thanks

@Pupyi, Welcome to HP Support Community,

Thank you for posting your query regarding the print quality issue; I’m here to help by guiding you through steps to resolve this issue

Update Printer Firmware (Update the firmware on an HP printer | HP® Support)

• Go to the HP Customer Support - Software and Driver Downloads page. Enter your printer model number and search for the latest firmware update. Follow the instructions to download and install the firmware update.

Check the paper, print settings, and quality of the file being printed

Make sure your print job is set up for optimal print quality results.

1. Check paper type and condition. Make sure the paper is appropriate for the print job and in good condition.

• Use paper designed for HP LaserJet printers, which is designed to handle the additional heat produced during the printing process.
• Some paper might not absorb toner as well as others, causing faded or smeared prints.
• Use clean, wrinkle-free paper. Wrinkled or curled paper can cause dark, horizontal defects.
• Do not use paper that is too rough. Smoother paper can result in better print quality.

2. Loading paper according to the print side: Typically, the smoother or glossy side is the print side, and it is loaded with the print side facing up in the input tray.

3. Loading paper according to the print side. Load paper into the paper tray with the print-side facing up. Typically, the smoother or glossy side is the print side.

4. Check the print job settings: From the application you are printing from, click File > Print, and then click Options, Printer Setup, or Preferences, or open the Paper Type/Quality or Media & Quality menu.

Make sure the color, paper type, paper size, and quality settings are correct for your print job.

5. Check the quality of the photo or document: Use editing tools to improve colors, brightness, contrast, and any other appearance settings. Higher resolution photographs and graphics result in clearer prints with more accurate colors.
