    Steven: A thorough cleaning of the glass (after I found it) alleviated the problem. I can now copy without vertical lines. Thank you. FE

I would look at the scanner. It is not involved in the printer process but is in the copy process. Clean the glass with a glass cleaner and soft cloth. Remove the glass and also clean the lamp assembly. If either part has a dark mark on it it would leave a line on the copy. If this does not solve your problem and the unit is several years old I would replace the lamp. Let me know if you need more assistance.

Thanks for using FixYa and for the generous rating.

If this doesn't appear when printing from computer and olny when copying or faxing, it means that the scanner glass has a spot on it. Please refer to the manual on how to clean the glass window, or go to this page on HP support site to view an image on how to do it:
The one on the left refers to your model; click the IMAGE button to see an animation.

HP 3050 vertical black lines during fax

OK, from the desciption i can assume several things here are some option.
If by receipt you are talking about the confirmation the unit prints the the problem is likely dirty glass.
You would also get the lines when you make a copy using the ADF.
Open the lid there are two areas of glass the thin strip is likely dirty and needs to be cleaned.

If by receipt you mean pages you receive from someone else, and not printed or copied on your machine, then their machine has the condition described above.

If everything has the lines then you have a toner or fuser problem:
This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the smudge or marks on the page the problem is most likely the cartridge but NOT the fuser.
If the page is clean the problem is most likely the fuser.
Hope this helps

HP 3050 - vertical black lines

You say that the scanner glass is clean, but it takes next to nothing to cause these lines. Couldn't hurt to chack again (if you havent cleaned it 6 times already).....anyway, I found this document that is not specifically for your machine, but the menu commands should be the same:
Recalibrate the product scanner:
  1. Press ENTER/MENU on the control panel of the product.
  2. Press the < arrow key once to display Service and press the ENTER/MENU button.
  3. Use the < and > keys to select Scan Correction and press the ENTER/MENU button.
  4. Insert a blank, bright white piece of letter (8.5 x 11 inches or 216 x 279 mm) or A4 (8.3 x 11.7 inches or 210 x 297 mm) paper into the document feeder tray.
Good Luck, and please rate the response :)

Printer putting line down the page

I had a hp 3050 yesterday with two vertical lines running down the page when making a copy. All I had to do was to pull open the top cover where you put the paper you want copied and cleaned the glass strip with a rag and alcohol and the lines were gone.
