      I suspect your laser (don't know what it's called on HP machines, but xerox usually calls them Raster Output Scanners.) Check if there's no obstruction in the path of light.

          I would check the path and clean the machine. As for the laser the part is RM1-1591-000CN laser scanner assembly. Sounds like there might be something blocking the laser or not opening the laser shutter. Hope this helps.

              It could be that the printer is trying to clear a jam, and it picks up more than one sheet. (pick up solenoid issue) What does the event log say? Try going in diagnostics and running sensor test and component test. Make sure sensors are good and that all motors/solenoids are working properly. 90% of all color laser issues are cleaning issues. Clean all the sensors. Make sure there is nothing in the path.

                              I agree it is likely to be the paper feed asm, but it's so much fun replacing it, I suggest cleaning the sensors first. I prefer troubleshooting to throwing a likely part at it. Saves time sometimes.
