You have dirt on the scan bar head so it produces an image on the paper.

When you print directly from the PC it does not use the scan bar

Take the glass off and clean the scan head

How do I copy a document on a lexmark x 1185 printer scanner copier


Turn the documents printed page away from you. (Document facing you, turn it around so that the print is on the backside)

Insert it in the top paper feed tray. Align the left side of the document page, with the alignment bar on the left side of the top paper feed tray. (Put the left side of the paper against the plastic bar on the left side of the paper tray)

Computer running, Windows loaded. Go to Start>Hover your mouse cursor on All Programs>Lexmark>Lexmark Printer

Click on the Copy function, and go to the Properties window to set how many copies you want, (Default setting is 1), what size paper you're using, and so on.

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

The small glass surface at the top of the scanner bed had some gunk on it. I scrapped it off and the line went away! Yay!

Troubles with copying


Pull the Top Loading Document Feeder up towards you from the back, to open and view the clear strip (perspex). I also had this problem, and fixed it by cleaning this strip. for future reference don't use whiteout on papers your going to fax/copy ;)

HP Laserjet 3050 paper jam


The rollers may be worn so it is not getting picked up evenly. Also, be sure that your paper tray in aligned properlyand guides are keeping the paper straight. If both of these seems to be good then there may be something in the paper path.

Scanning Problems


I need some more information are the lines horizontal or vertical? Does it print fine from the computer? Does this problem only happen when you scan an item in and then print it or copying an item then print it? Also when you get this output do you have some of the text and lines or just lines?
