The paper might not be engaged with the feed rollers. The paper-width guide is pressed against the paper stack too tightly. The paper tray is not completely inserted into the product. The paper settings in the print driver do not match the paper loaded in the paper tray.
The way I solved it was to restart the print spooler. This will reset Window`s communication with the printer and Windows will no longer think the printer is out of paper.
Check the paper rollers and clean any particles of dust or dirt if you continue getting error messages indicating there is no paper in the printer. Make sure the stack of papers isn`t crumpled or bowed. Remove the stack of papers and replace the tray. Replace the paper and take it out again.
For HP Laser printers, click the Paper tab, click the Original Size drop-down, and then make sure the paper size matches the type of paper loaded into the printer. Click the Output Size drop-down, select Same as Original Size, and then click OK.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
Dust, paper fiber, and other debris might accumulate on the pick rollers and cause paper feed issues. To help prevent paper feed issues, clean the rollers inside the printer and in the duplexer (if equipped). If the other steps in this document fail to resolve the issue, then reset the printer.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.
What`s happening is that the drum or rollers could have a fingerprint or dirt that is smudging the toner on the page as it passes through to the fuser. It is normally caused by the rollers. If the marks are always in different places, then it`s most likely to be the drum.
When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.

HP Officejet Pro 8500 Wireless with fake paper jam
ANSWER : HP Officejet is by far one of the frustrating piece of equipment I have ever owned. I bought it as unused in the package, at that point no warranty left. less than 6 months and 500 pages the white cog gear wheel broke. Luckily with instructions in this site I manage to glue it back together. Then I bought new ink – problems started as they were not original HP 30$ per cartridge. Ordered originals (here in China), took over one week to get them. Then found out that printhead needed to be replaced => more than 100$ spent. Still constant problems: If my wife kids print, I need to be stand-by as you never know what happens. Really an Office level equipment. After cleaning one paper jam I broke the encoder tape, took me another 4 hours to get it fixed. Then broke the cog gear again and got it displaced. Another 4 hours. Only reason I am not throwing this s***t out of window is that there are still ink left. Luckily this drinks them like a horse, for sure I will no more buy new ink. I will get a new laser instead, and not from HP. About cog wheel fixing: make sure that the white wheel is positioned correctly so that the small torx in shaft goes into the slit in the white wheel. When fitting the black cover back, make sure that the white washers on both sides fit into to slits of the black cover. Good luck.
