Officejet 3835 printing black roller marks vertically on the page

[Sonic751]

My Officejet didn't feed paper correctly and printed a whole document but not on paper. 

Since then after cleaning cartridges etc it now prints roller marks in the centre of the page vertically front and back. I have done all of the cleaning possible and there is now no ink on any of the rollers that I can see. 

I have re installed drivers as well.

I also checked my warranty and my warranty began before I had even purchased my printer, so has now expired

Any help would be gratefully received, as I had a similar problem with my previous officejet but went and bought this one

Welcome to HP support community.

Clean the paper feed rollers

1. Turn off the printer, and then disconnect the power cord.

      WARNING: 

   Disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.

2. Disconnect the USB cable, if it is not already disconnected.

3. Raise the input tray.

   

4. Lift and hold the input tray shield.

   NOTE: 

   Do not remove the input tray shield. The input tray shield prevents foreign debris from falling into the paper path and causing paper jams.

5. Look down through the open input tray and find the gray paper pick rollers. You might need a flashlight to illuminate the area.

   

6. Dampen a long cotton swab with bottled or distilled water, and then squeeze any excess water from the cloth.

7. Press the swab against the rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove dust or dirt buildup.

8. Lower the input tray shield.

9. Allow the rollers to dry for 10 or 15 minutes.

10. Reconnect the power cord to the rear of the printer, and then turn on the printer.

11. Reconnect the USB cable to the printer if necessary.
