Hp HP LaserJet 4

HP Laserjet 4 prints after 6 to 8 pages

The printer initially prints a blank page working up to a pretty good print after 6 to 8 pages, and prints fine if I continue to print. If I let the printer sit then try to start printing the same problem occurs. I've taken the unit above the paper tray out and cleaned it. It looks fine to me. Could the heater button resting against the roller be taking time to warm up? On a separate problem, I get a paper jam where I have to open the back flap and pull out the logged paper fairly often. I do have to use lighter grade paper for printing, or I get jams all the time. Thanks
