HP 670c 列印出空白文件 但列印服務又印得出東西來 - 印表機

聽聲音感覺印表機是有在印東西
但是出來的卻是一片空白
然而使用列印服務的校準和清潔列印墨水匣
卻又煞有其事地印出有顏色的東西

請告訴我如何解決
謝謝

Advertisements have us chasing cars and clothes,working jobs we hate so we can
buy shit we don't need.We've all been raised by television to believe that one
day we'll all be millionaires and movie gods and rock stars -- but we won't.
We're learning slowly that fact,And we're very, very pissed off.
