You need it serviced. If it is totally blank then the toner is not being placed on the paper at all, if the heat roller were bad you would just get black dust, or characters that blew off.
The fact you get nothing means the Toner cartridge is bad or the toner is not being placed on drum in the Cartridge, so it is not getting on the paper at all, this would be due to a serious hardware problem.
Dear All,
My HP LaserJet 1200 printer accidently began to print blank papers. Giving blank papers means all the mechanical parts working properly. I am sure toner is OK.
Do you have any clue?
Bye!
