From many months I've a problem with my HP Officejet Pro 8000 A809 (CB092A).
When I print a double sided sheet I get this behavor:
- a single white sheet come out
- a yellow led start blinking on the right button (the one with the paper drawing)
- if I push this button, the asked print is performed correctly, double sided.
If the document has >2 pages, the next ones are printed correctly.
If I print another 2 pages document, again double sided, I get the same behavior as above.
The same problem appears if I print from Win7, Win8 or WinXP pc. All printing via wired LAN.
Thank you in advance for any info that can solve the problem.
