Paper will not feeding
Cleaned all paper feed rollers.
Pick-up rollers not picking up the paper
The HP Officejet 6500 is a color All-In-One printer. Released in 2003. Model number: CB815A#B1H.
The typical problem is associated with the cog sliding out of position along the drive shaft. This cog can be viewed by placing a mirror (facing upward) just within, and to the right, of the paper feed tray to view the drive shaft (running right to left) above the compartment. Also, use a flashlight to illuminate the area clearly. You will note a plastic cog (geared wheel) positioned on the shaft. When properly set, this should be positioned on the splines located on the right side of the shaft, which would align it to the gear that operates the paper feed rollers. It is not uncommon for this cog to dislodge from the splines and slide toward the left. Simply slide it back (right) over the splines until it is perfectly centered to drive the paper feed gear.
Equally common is that the corresponding splines on (within) the cog may become slightly worn (unit is entirely plastic after all), which allowed it to become dislodged in the first place. To ensure it remains in place, most DIY's apply a thin application of Super Glue to the splines on the drive shaft, then slide the cog into place - ensuring its gears are perfectly married (positioned) to/within the gears that drive the paper feeder. Allow ample time to "completely" dry before testing the printer.
Hope this solves your problem.
