Bad printing quality HP Color laser 178nw

[EliskaCadova]

Hello

I have a problem with printing quality on my HP Color Laser MFP 178nw printer. It smudges the printed image and part of the image is printed repeatedly like a shadow at the end of the page. I have tried cleaning the inside of the printer and I inspected the imagining drum but I didn´t find any damage on it. I don´t know what could be the problem. Any help is appreciated. Thank you.

Hi @EliskaCadova,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Here are some steps you can take to troubleshoot and improve the print quality on your HP Color Laser MFP 178nw:

1. Check Toner Cartridges

• Inspect Toner Levels: Ensure that the toner cartridges are not low or empty.
• Reinstall Cartridges: Remove and reinstall the toner cartridges to ensure proper contact.

2. Clean the Imaging Drum

• Even if it looks fine, sometimes residue can cause issues. Use a lint-free cloth to gently wipe the drum surface. Avoid touching the drum directly with your fingers.

3. Run the Cleaning Cycle

• Use the printer's built-in cleaning feature, if available. This can help remove any debris or toner buildup affecting print quality.

4. Check for Paper Quality

• Ensure you’re using the correct type and quality of paper recommended for your printer. Low-quality or incompatible paper can lead to print issues.

5. Adjust Print Settings

• Check the print settings on your computer. Make sure you’re using the appropriate print quality setting for your document type.

6. Update Printer Drivers

• Ensure that your printer drivers are up to date. Visit the HP support website to download the latest drivers.

7. Inspect the Fuser Unit

• If the fuser unit is worn or damaged, it can cause smudging. If possible, check the fuser for any issues or consider replacing it if needed.

8. Print a Configuration Page

• Print a configuration page from the printer’s menu to check for any issues with the printer’s internal components.

I hope this helps.

Take care and have a good day.
