          As he reported that the drum was very dirty, very likely that toner had fallen on the laser lens, plugging the image formation on the drum.

              Not sure if this is your issue but something to check,

              Black is known to dump developer if Image unit contact is loose. Maybe it dumped most of the developer and reason getting a half of print on page. There is a modified bracket to hold IU in tighter for better contact. This was more common on the older models with similar design, C451, etc.
