Probably a bad cleaning blade in the yellow drum unit.

If the machine is an MFC3420c using the LC21/800 style cartridges, then the ink cartridges are sitting on it.

slide scan is not an option on that model. slide scanner is an option in some models of scanners. I have a HP one as most HP scanners have the setting built into the scan firmware that lowers and higher the light to get correct scan. brother model will not do this its just normal scan setting.
