machine prints lines across copies

Hi,

Does it happen when printing from a PC or only when making copies using the printer's control panel?

If it only happens when making copies, then does it only happen when using the ADF, the platen glass or both?

If it only occurs when using the Automatic Document Feeder (ADF) and not when making a copy via the platen glass, the issue is commonly due to small marks or debris on the scanning glass area that lines up underneath the ADF roller. Small smudges on the platen glass can cause "streaks" to be produced as every inch of the paper fed via the ADF passes over the area and is picked up by the scanner. The scanning light sits in this area when using the ADF.

If it occurs when using the platen glass you will need to carefully and fully clean the glass in the scanning area. There can also be a strip of transparent plastic on which there can be a mark or smudge. Look for scratches, tiny spots and marks of any sort. You can use a soft lint free cloth either dry, or just very lightly moistened to clean the glass. You may have to scrub (gently) to remove certain types of marks.

You may also wish to clean the underside of the lid.

NOTE: do not spray a cleaning solution onto the glass.

After cleaning the platen glass, run four to five blank/clean pages through to test it and see if the streaks still appear
