Mine is the same, equally spaced just like yours but a different repeating pattern. Also, their darkness is light at the top and bottom of the pages and progressively darker the closer you get to the middle. However their vertical positions, while always equally spaced a little less than 1.25" apart, are not at the same relative offset position on different pages. However the same text it is supposed to print always matches with the correct margins. So not sure what that points to. Certainly the drum is printing what its given. But what is it given and how? If I didnt know any better I would think it was a software problem but its the same from both a PC and an Iphone.</P><P>Was fine before. But it just went through a cross country move, well packed and well padded in the box, however maybe it got tossed around and something happened. It was also in a very cold storage locker for a month. Did the condensation and self-cleaning things. However the near exact result every time, down to the same pattern itself on every page printed, is quite odd.</P><P>&nbsp;</P><P>Edit: Printer is LDP236dw</P> Fri, 28 Mar 2025 20:23:57 GMT JohnSmythe 2025-03-28T20:23:57Z https://community.usa.canon.com/t5/Office-Printers/Canon-MF8280CW-Printing-Dark-Horizontal-Lines/m-p/533320#M25507 <P><STRONG>my printer is printing dark lines across the page despite new toners. &nbsp;please advice if this is printer head issue?</STRONG></P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.jpg" style="width: 4032px;"><img src="https://community.usa.canon.com/t5/image/serverpage/image-id/63898iD7F72AEFF6BEA88D/image-size/medium?v=v2&amp;px=400" role="button" title="image.jpg" alt="image.jpg" /></span></P> <P> </P> Sat, 08 Feb 2025 17:09:49 GMT https://community.usa.canon.com/t5/Office-Printers/Canon-MF8280CW-Printing-Dark-Horizontal-Lines/m-p/533320#M25507 Rahulnalgirkar 2025-02-08T17:09:49Z https://community.usa.canon.com/t5/Office-Printers/Canon-MF8280CW-Printing-Dark-Horizontal-Lines/m-p/541847#M26177 <P>Hey there.</P><P>Any idea what that was?
