remanufactured / compatible toner? sounds like defects to me. try OEM, or another supplier

SOURCE: hp laserjet must manually push button to print

Hi,

Please print a configuration page from the control panel of the printer
- Menu > Information menu > print configuration.
- Check for paper handling details.
Following setting should reflect.
Tray 1: Any size / Any Type
Tray 2: A4 size / Plain Type

If the above settings are not reflecting in the configuration page, please change accordingly by browsing on the control panel of the printer to:
Paper Handling Menu >
Tray 1 Size: Any
Tray 1 Type: Any
Tray 2 Size: A4
Tray 2 Type: Plain

Let me know if that helps to solve the issue.

Regards,
Nikhil.

This is a known issue with 'host-based' printers like the 3600. You need the PCL5 driver, which this printer will not work with. You need a different printer, such as the HP 3520.

This page will explain it all.
