How to get images without jpeg artifacts ?

Photosmart 5520
Microsoft Windows 10 (64-bit)

How can i disable the jpeg compression on this device? I always see jpeg artifacts, regardless of file type. The "optimize for image quality" option doesn't seem to help. Vuescan does the job, but it should not be necessary to buy 3rd party tools to get maximum scan quality...... Any solution? Suggestions are appreciated... thanks.

@Bas17, Welcome to HP Support Community!

 

Are you trying to scan images or documents?

If you are trying to scan images, save them in the .png format as it retains the image quality.

 

Also, refer to the document HP Printers - Improving Scan Quality for help.

 

Hope this helps! Keep me posted.

How to get images without jpeg artifacts ?

Hi TEJ1602

 

Thanks for your reply.

The problem with the jpeg artifacts is independent of the file type. So saving in a lossless format (png, bmp, tif) doesn't resolve the issue. It looks like the jpeg compression is done by the scanner's firmware to speedup the scanning process by lowering the amount of data to transfer over the network.

 

It looks like i'm facing the same problem as discussed in this thread:

 

https://h30434.www3.hp.com/t5/Printers-Archive-Read-Only/Bad-scan-quality-on-HP-Photosmart-5515-and-...

 

But in my case setting the option "optimize for image quality" seems to have no effect at all.

The scanner is able to transfer image data without jpeg compression (aka raw data) as this is proven by using Vuescan.

Somehow the HP tool doesn't do the job...

 

Kind regards

Bas17

Have you tried using the HP Smart App to scan? If no, install the app and try scanning.

 

Keep me posted for further assistance.

Just tried, no difference. I used the save to pdf option as this app doesn't support any lossless file format?!? What the heck HP?!

There is no optimize for image quality option either. Only a compression level setting low/medium/hi (I had expected NONE as an option here!!!). That is just the point, i want uncompressed (aka raw) image data. No compression due to the file format and no compression due to the scanner's firmware to save bandwidth/speed-up data transfer. Disappointed... 😞

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details). 

 

If you are unfamiliar with how the Forum's private message capability works, you can learn about that here.

 

Thank you for visiting the HP Support Community.
