Black wide line at the bottom

Hi,

It is an Wide Format printer. Did not have an IBT. Could be also an scratched drum or an damaged magnetic roll on the developer module.

If this is a copy clean the cis/scanner. Section 7 of the user manual

If this a print you have contamination of a sticky sort on the drum or ibt cleaner and need a tech

The printer blueprints have a thick black line at the bottom. How can I fix that ?
