HP 3015 stopped scanning. It still prints, and goes through motions of scanning, but page is blank

is the toner cartridge original or reffiled.
Try with original one.
check if the image you print is correct printed on drum
to do this print something and when the printer start to pull the paper stop the printer by open a door. then pull out the toner cartridge and look the drum if the image seems ok If you see bad image you have problem with laser scanner or charge of drum.

please check cartridges nose and clean for tissue paper and solve the problem

Most common cause of this issue is low toner. Best solution is to remove the toner cartridge and while keeping it mostly level, shake it from side to side to level out the toner. Then re-install and test. If this fixes your issue then just be aware that the toner cartridge is starting to get low on toner.
Now if the white streak is very fine and the above procedure does not work then it is most likely something stuck to the scanner glass. To test for this print out a report from the operation panel or if you have the machine connected to a PC print something from there. Are your print outs ok? If so it means that it is definately something on the scanner glass. To locate it and clean it just make a copy of something. Now take that copy with the blank line on it and place it in the feeder just as you did with the original. now wherever the blank streak is lined up on the machine is where the spot is going to be on the scanner glass. Just open the cover where the documents go in and look for the strip of glass that runs from side to side. Your copy passes over this glass when it is scanned. Where the blank line hits this glass is where the trouble spot is. Just clean the glass with a cloth that has some glass cleaner sprayed on it. This should resolve the problem.

I have the same machine and I can not fax or scan. Do I need special software?

Try re-installing the drivers and application for your HP All-In-One.

I have this printer with the same problem , worked fine for 1 year, printed over 1600 pages total ( according to the built in HP program that records how many pages I printed and how many times I used the printer) then it stopped printing. The ink cartridges are new, the software is fine, and it says ink levels are good. It physically goes through the motions of printing, loads the paper, makes all the normal sounds it used to and pushes out the paper when it's done - but the page is blank. I did some surfing and read some info that some HP printers are pre-programmed to stop certain functions so you buy a new printer. I know that might sound crazy. How long have you had the printer and how many pages do you think you printed?

Make sure your set to "print" and not scan. The blank pages may be a 'print' of the lid on your scanner top

if your printer is under waranty then get it to the service center.
