Hp laserjet 1320 printing blank pages

Hi, If you have replaced the toner acrtridge and still the printer is printing blank pages than it please make sure you have removed the maler strip of the toner cartridge if yes than perform engine test page of the printer wherein remove the side panel and there is a small button to press and it print engine test page and that will bypass the formatter if the engine test page is also blanik than it is the issue with transfer roller (Which create the image) Power Supply( Create image on transfer roller) or Laser/Scanner assmbly which creates the laser image on transfer and all these three parts are not customer replacable(Hardware Issue) and customer need to get the printer repaired by HP Authorised Engineer.

check printer door, there is a small plastic piece wich pushed down (to open) lasser scaner cover. if this piece is broken you can get blank page
