Re: Yello bands on KM c1070
Hi,
it happened to me sometimes too and not only on yellow.
When it happen, below what i do ( KM technical bulletin ):
- change corona
- charge new developer
- i check that firmmare is at least ver. G00-17
- set dip sw 46-4 to 1 ( this increase developer mixing speed )
- set dip sw 44-5 / 6 to 1 / 0 ( this increase developer stability by periodically toner banding/refreshing )
- set dip sw 49-6 / 7 to 1 / 0 ( this increase developer stability by periodically toner banding/refreshing )
- set dip sw 59-7 to 1 to prevent second tr. roller contamination fron toner banding
Hope this help
Alex

Re: Yello bands on KM c1070
It's always the yellow!! I have had it happen randomly on various machines. No rhyme or reason for it. After a developer re-charge all is fine until it's regularly scheduled developer change. I always keep a fresh bag of yellow developer on hand because of this. Fortunately, KM recently lowered the price on the developer for this series fairly dramatically. There are also a few bulletins for "developer screw marks" on KM but nothing very helpful that hasn't been mentioned already. Also, as mentioned above. Don't try to cheat the developing unit life and let them go past 1.2 million.... That can be an expensive lesson.
