Canon IRC2550 streaks

[Will]

Have a Canon IR c2550 with the cyan drum unit leaving streaks along back edge about 1" wide. If I replace drum imaging unit
are there any counters reset or setup routines to run in service mode?

No, just replace the drum, nothing else to do.

But I usually do a full auto gradtion, but this is just me!
