print quality from scanned documents - when I scan a Word document or a pdf, the scan adds red marks. When I print the scanned document I get these red artifacts; when I print the word document the quality is fine and there are no red artifacts on the printed page. I am using an OfficeJet Pro 9135e All in One Printer,

@mrkfkus, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Red Artifacts in Scanned Documents! 

We're thrilled to have the opportunity to assist you and provide a solution.  

If you are experiencing red artifacts in scanned documents using your HP OfficeJet Pro 9135e All-in-One printer, here are a few troubleshooting steps you can follow to resolve the issue:

Check Scanner Glass and Document Feeder: Ensure that the scanner glass and document feeder are clean and free from dust or debris. Even tiny particles can cause scanning artifacts.

Update Printer Firmware: Make sure your printer's firmware is up to date. You can check for updates on HP's official website or through the HP Smart app.

Adjust Scanner Settings: Alter the scan settings to improve the quality. Reduce the scanning resolution or change the color settings to black and white. These adjustments might eliminate the red marks.

Calibration: Calibrate your scanner using the built-in tools provided in the printer’s maintenance menu. Calibration can help correct color inaccuracies.

Use HP Scanning Software: If you are not already using it, install the latest version of HP scanning software (HP Smart or HP Scan) and use that to perform your scans. HP’s software is optimized for their devices and may reduce scanning artifacts.

Check for Software Conflicts: Ensure that no other scanning software is interfering with HP’s scanning process. Close any non-essential applications.  

Hope this helps! 

Take care, and have an amazing day!
