• HP Officejet Pro 8600: Document feeder causing vertical lines in copying and scanning

  When I copy or scan via the document feeder I get two vertical lines on the copy or scan.  How can I fix it?

  Hello @aadmin, hope you are well!

  Thank you for becoming a member of the HP Forum. It's a great place to get help from the community, to get suggestions and find what has worked for others.

  I understand that you are facing problems while scanning / copying using the ADF. Please, try the following steps to resolve this problem.

  1. Make a blank copy using the ADF. Ideally, you should get a blank document with the two vertical lines.
  2. Keep the page out on your dish / the main scanner bed facing you.
  3. Follow the line or streak on the paper to the box on the ADF glass is the origin of the problem. Carefully clean the thin "strip of lid of scanner ADF white' and 'the band glass ADF Scanner' with a damp lint cloth.
  4. See the figure below. 3 is the glass Strip ADF & 2 is the white cover ADF scanner.

  

  These measures should be the case, I would like to know the results.

  See you soon

• HP Officejet Pro 8600: Thin vertical lines when printing photos

  The printer referenced did a fabulous job to print photographs.  In this case, the printer is fairly recent and has recently recently consumed the original cartridges when it was decided to try to use it for photo printing.  Therefore, the fabulous results were extracted relatively new cartridges and consisted of at least a dozen photo printing in various sizes.  Then all of a sudden these thin vertical straight lines began to appear in print.  They are equidistant on the full image.  That they appear in the printed image.  When using paper letter (8.5 x 11) to print an image cropped at 8 x 10 with landscape orientation spacing is about 1 1/8 (one and one-eighth) inches or 8 evenly spaced vertical lines.  Somewhat like the photo was divided into 8 columns.

  According to the printer built in ink gauge, that the cartridges are now just a little more than half full.

  These lines are narrow enough so that they are not very visible when printing on normal paper (copy).  They would probably be imperceptible on many kinds of printed documents.  However, they become quite noticeable and reprehensible when using good quality (in this case HP) photo paper to print photos.

  Absence of a printer resolution is not good for photo printing.

  In addition to the troubleshooting suggests that the problem is not due to the printer, but rather to the software used to perform the printing. It was not immediately obvious that I printed only photos using Picasa and it worked fine and then all of a sudden the problem developed. However, I have now tried to print the same photos with other software and there is no problem for the steps.

  The Picasa forum also has many messages wanting to be the same or a similar problem to what I have experienced. Unfortunately, there doesn't seem to be an explanation for a repeatable cause, nor a specific solution. Some hacking autour with the settings and options seems to be in order. If it does not then print with other software may be necessary.

• OfficeJet pro 8600 more: 2 black vertical line when scanning only

  I get 2 vertical black lines while scanning using the ADF. This does NOT happen when you use flat bed scanning. Also, this does not happen with copies in the ADF or flat bed - scan only using the car power.

  Not an expert on your device, but if you look on the side of the adf, where the paper feeds, you open the lid to the scanner glass is displayed.  Now on the left side is where the adf feed above to scan paper is on the side left where there will be some dirt or material causing lines.  Usually, you can take the copy that came out and line up so you can see the dots making line.  Sometimes, you need to use your nails to kind of scratch material out of the glass.  I usually rub really hard with some windex first, and if that does not work, I line up the and scrape the residue out of the glass.  Again, it will be on the left side of the window in an inch on the left side.

• LaserJet pro m252 dw: occasional spurious vertical lines

  I create a pdf from latex file that includes a border color for the text box using the installation of "mdframed". In print preview, it looks fine, but when you print, some of the borders have a vertical line of the same color and the same width as the border on the left edge and right out of the box and the height of the box.

  This only happens for some of the boxes, mainly those who are quite narrow.

  PS This does not occur when printing b/w of same page toa HL 2040 brother

  In response to my own question:

  Other tests showed that this problem occurs when printing via PDF-Xchange Viewer, but NOT with SummatraPDF.

  So it looks like an application problem not the printer.

• OfficeJet Pro 8500 has vertical line from top to bottom after a copy or scanning via adf

  Each copy or scan do using the automatic document feeder to my HP Officejet Pro 8500 a shows a vertical line from top to bottom left of each page. I have cleaned the printer at all parts of the feeder, - nothing dirty in fact found. When I copy or scan the glass plate there is no vertical line on paper.

  Anyone have the same experience with this printer?

  Usually if the scanner works on the dish, but product line in the scans from the ADF, it's because of something on the glass.  Have you tried to shine a flashlight down on the surface of the small approximately 1 in. piece of glass on the left side of the bucket?  This is the strip of glass used for the ADF.

  Like trying to clean the white strip, located on the lid above the glass of the ADF, well clean to make sure there is no debris on the support that can cause this line appears.

  * Make sure that the printer is plugged into a direct socket, rather than a surge protector.  The 8500 has protection against overvoltages integrated in the device and an another surge in the circuit protector can sometimes cause lines.  However, usually this causes lines in both ADF and flatbed scans.

  There is also a document provided by HP with the steps to troubleshoot issues when a line is present in the copies/scans.  The document can be accessed here.

  I hope this helps.

• HP Officejet Pro 8600: Printing vertical lines when you use doc auto power

  I cleaned the optical window such as suggested in other posts. However, this has not fixed the problem for me.

  The vertical line is the center of the page, from top to bottom.

  Hello @KR76,

  I'd be happy to help you with your problem of copy on your OfficeJet Pro line 8600.

  Basically, the line is created if any part of the scanner glass and the scanner cover fingerprints fingerprints, stains, lint, dust, or other debris or scratches. To resolve this problem, clean the ADF scanner glass Strip, the ADF white plastic band on the underside of the scanner cover, the underside of the scanner cover and the scanner glass. You need to repeat the cleaning several times to fix this.

  The document that will guide you through the inspection and cleaning of these independent pieces would be; Vertical stripes, lines or streaks in the Copies, faxes, or scans.

  Take note of the following in the document;

  Warning: Only use a glass cleaner to clean the scanner glass. Don't use of cleaners containing abrasives, acetone, benzene, or carbon tetrachloride. These substances can damage the printer. Avoid alcohol isopropyl (rubbing alcohol) because it can leave scratches on the glass.

  Warning: To protect the scanner are not spray the glass product directly on the glass.

  Please let me know if any of these steps has resolved your problem, or if there is anything else I can do to help.

  I look forward to hear from you!

  Thank you

• Stop and run option is missing from the Start Menu.

  Original title: Administrator group of experts.

  On the Admin Panel when I want to close I normally press start and the "closing". However the button turn off disappeared and only shows button "quit". In addition the 'run' button is gone as well. How to restore it back to normal?

  It will help with these situations... and, this lesson, I've added a few new commands to my answer of registry file generic copy/paste for these kinds of things:

  If you see things like this:

  You do not have sufficient security privileges to restore your system.
  The System Restore tab is missing from the my computer properties.
  System Restore has been disabled by group policy.  To turn on system restore, contact your domain administrator.
  The System Restore tab is available, but the turn off System Restore (disabled by Group Policy) box is grayed out.
  The task manager has been disabled by your system administrator.
  The registry editor has been disabled by your system administrator.
  The task manager has been disabled by group policy.
  The registry editor has been disabled by group policy.
  The command prompt has been disabled by your administrator.  Press a key to continue...

  The usual advice are something in the sense of "something has been disabled in the group policy...". ", and it is probably true that something has been disabled, but you know what something is and what it takes to do about it.

  If you are using XP Home Edition, you will get away with advice to use the Group Policy Editor, because there is no Group Policy Editor in XP Home and that really doesn't tell you where to look in group policy, even if you run the Group Policy Editor.

  You need a complete solution that works for all versions of XP and requires no hunting around in the Group Policy Editor or registry to find where things are that have been disabled.

  Unless you have disabled these things on purpose, chances are good that your system has a malware infection.  The malware knows what tools you use to try to find and remove, for the malware disables the things you are more likely to consume and prevents them from running if you can't find the malware and remove it.

  If your system has this kind of affliction, all malicious software tools you currently use or have used failed to protect your system so that you can expand your horizons malware detection and prevention to prevent these kinds of afflictions in the first place.

  The malware will be happy you trick into thinking that you need to so something drastic to fix your system - as a facility repair, system restore point or a total reinstallation of XP.  This is what it would be like you, but these measures are not necessary.

  You must solve the immediate problem of the tools does not, then scan your system for malware when you are finished.

  No matter what kind of malware you've used analytical tools, they are unlikely to solve this problem, because they cannot tell if the changes made to your system have been on purpose (you or an administrator who makes them) or some malware changed them, so the analysis tools will let these things alone (it's usually a good thing).

  If your system is afflicted in this way, there are probably other things that also do not work - like the registry editor, System Restore and the command prompt, so fix them all at once even if you have not discovered they are broken again.

  These commands from registry removes the registry entries that are stop opening programs.  Although the registry entries do not exist, these commands are safe to run and will work for all versions of XP.

  Before making any changes to your registry, back up the registry with this free and popular tool:

  Open Notepad to create a new text file:

  Click Start, run and enter in the box:

  Click OK to open a new Notepad file.

  Copy and paste the following lines of text into the new Notepad file.

  Save the new text file with extension .reg on your desktop or somewhere you can remember with a name you can remember, something like:

  enableit.reg

  After you save the file, close Notepad.

  Locate the file enableit.reg on your desktop and double-click it.

  Alternatively, you can right-click on the enableit.reg file, choose open with... and select the registry editor.

  Answer in the affirmative to the question... Are you sure you want to add the information in the registry?

  You should then see a message that information has been registered in the register.

  Reboot your system and test.

  You can delete the enableit.reg file when you are finished.

  If the registry editor has also been disabled, we first fix (not a problem).
