Make Non-repro Blue Lines Disappear

[Dezigner99]

I do a lot of hand sketching on non-repro blue lined graph paper and I'm used to copiers not picking up the faint blue grid lines when it scans and copies the sketch.    

Is there a setting on LaserJet MFP M127fn that will make the blue lines non-reproducing and still keep the other lines dark and crisp?  Everything I try fades the ones I want to keep out.  

Thank-you.

Hi @Dezigner99,

Welcome to the HP Support Forums!

I see that you're wondering how to remove the grid lines when printing a document HP Laserjet Pro MFP M127fn Printer. I would be happy to help you and please remember to return to this thread and mark 'Accept as Solution' if I have successfully helped you resolve the issue. If you wish to say 'thanks' for my effort to help, click the 'thumbs up' to give me a Kudos.

I understand why you would like to be able to remove the grid lines when copying or scanning your sketches. The printer does not have the ability to ignore what is on the paper. However, there are a few ways you might be able to accomplish this task.

1. Scan the sketch to the computer and use photo imaging software (Photoshop) to remove the lines prior to printing.

2. Scan the image to the computer and adjust the brightness and contrast setting before saving, to see the lines fade away enough.

Scan the document

Select your version of the HP scanning software for steps to scan the item.

HP Scan

Follow these steps to scan a document as editable text with HP Scan software.

1. Open the HP Scan window with one of the following methods:

   • Double-click the HP Scan icon () for your printer on the Windows desktop.

   • Click the Windows icon (), click All Programs, click the HP folder, click the name of your printer, and then click HP Scan.

2. Click Save as Editable Text (OCR).

   Save as Editable Text (OCR)

   Use this option to scan text documents that you can then edit. You must have Optical Character Recognition (OCR) software from HP (your printer might have shipped with a Readiris CD, which contains OCR software), or from a third-party vendor (OmniPage, FineReader, TextBridge, SimpleOCR) installed on your computer to save the text as editable.

3. In the HP Scan window, to the right of each scan option there are default recommended settings for scan size, output type, resolution, and file type (for text scans only). Use these default settings unless you need to customize the settings for your scan.

   • To change the basic scan settings

     Click the drop-down arrow () for the setting that you want to change, and then select the setting you need.

   • To change the advanced scan settings

     Click Advanced Settings to change the following settings (depending on your printer):

     • Adjust the scan size, output type, brightness, and contrast

     • Select the file type and quality setting

     • Set the OCR editable text language

     • Specify the file name and the location to send scans on the computer

     • Specify to create a new file for each scan or to combine multiple scans into one file

     • Specify how the HP software completes the scan action:

       • Open the scan file

       • Launch Windows Explorer

       • Email the scan file

       • Do nothing (saves the scan to the specified location)

4. When the scan completes, you can adjust the lightness or darkness levels, crop the scan file, or change the orientation, and then perform one of the following actions:

• Click Save to capture the scanned file but leave HP Scan open.

• Click Done to capture the scanned file and close HP Scan.

• Click the Plus sign () on the left side of the window to scan additional pages.

• If you are not satisfied with the scan, click the X icon () to delete the scanned file, and then click Back to scan a new file.

3. I would try bypassing the grid lines using the copy settings to adjust the Lighter/Darker setting. Once you have copied the sketch and faded the grid lines, try copying that printout using the Lighter setting. Perhaps if you try this it would reduce the sight of the grid lines.

Copy the document or photo

Use the printer control panel to select copy settings and start the copy job. Use ID Copy to copy multiple items onto one page.

Copy the document or photo

Change the settings, contrast, and number of copies, then copy the document or photo.

1. Press the Copy Menu button , then use the arrow buttons to navigate specific copy settings:
   • Reduce/Enlarge: Use this setting to reduce or enlarge the image of the original on the copied page.
     Use the arrow buttons to choose a preset size, or select Custom, then enter a percentage between 25 and 400.
   • Optimize: This setting allows you to optimize the copy quality based on the type of job, such as text or photos.
     Select Text, Picture, Draft, or Mixed.
   • Paper: Change the paper type or paper size for the copy job.
   • Collation: Collate your copies.
   • Set as Defaults: After selecting the settings for your copy job, select this option, then select Yes to save your settings as the default copy settings.
   • Restore Defaults: Restore the factory copy settings.
2. Press the Lighter/Darker button , use the arrow buttons to select the darkness level, and then press OK.
3. Press the Number of Copies button , then use the keypad or arrow buttons to enter the number of copies.
4. Press the Start Copy button to start the copy job.

Souce

4. Alternatively, I would copy a fresh sheet of the grid line paper and darken the copy as much as possible. Using the copied grid paper under the plain paper in hopes that it will show through.

Please respond to this post with the result of your troubleshooting. I look forward to hearing from you. Good Luck! 🙂

Drakster,

Here's a link that explains what I'm looking for.  

https://en.wikipedia.org/wiki/Non-photo_blue

I guess I'm trying to do something that can't be done successfully with a $150 machine.  Most copiers that I have worked with over the past 20 years are automatically setup to ignore the faint blue lines.    

It's not worth the time investment to Photoshop out the lines and changing the brightness/contrast settings always washes out the parts of the drawing that I want to keep crisp and sharp.  

But, thanks for trying to help.
