Canon ir3300 printing black dots on bottom of paper
Dear
A scan copy of the printing and information on paper setting would bet better to understand. however the dots appeared at bottom may cause due to the drum unit corrosion or spots on its surface. Try to clean drum and PCR roller with cotton cloth dampen with isopropyle alcohol. and warm up with rubbing dry cotton on the surface of PCR and drum. Note don't work with direct light or sun light.
Try to clean the transfer roller with soft brush.
Thanks.
