I think that might be a board issue. All attachments are suddenly showing up tiny.

The message board I mean. The pictures you post show up too small to see any detail.

These types of ghost prints are usually created in the imaging unit and/or the fusing unit.


It doesn't seem like it but it could be incompatibility problems
If you haven't done it try this


1-Do not print it from a browser like Google Chrome, Firefox or Microsoft Edge, instead use a PDF program like SumatraPDF and print from it.

2-If you are printing from a recent version of Mac or Windows 11, try printing from a PC with Windows 7 and make sure it has the correct drivers

Agree with Gab, repeat image / ghosting is caused by drum or fuser.

Re: Black text and black background duplicate

This is happening with plain paper, or are you using card stock? If you're using card stock, have you set the paper type correctly?

If it's happening on plain paper, send a print job, and open the door to try and catch the paper after it's gone through the image transfer, but before it hits the fuser. If the paper has the issue before the fuser, it's probably an issue with the drum or the erasure lamp. If it happens after it hits the fuser, it's probably the fuser.
