Sharp ar 651- toshiba wannabe, background

[DEGUY]

I have a ar651 where the very 1st page is clean but with each additional page in lets say a run of 20 copies the background gets progressively worse. unit has 200,000 and factory toner. I do not do much with this but since we sell Sharp I should know Toshiba or thats what the sales dept tell me. Please all help is more than welcome

I believe there is a bulletin about this, vacuum out the toner recycling section then run a bunch of skyshots until it goes away, I believe it says to do like 200, or just vacuum it and replace the developer, this is an older model and you'll probally be better off replacing the dev, you can also adjust the amount of recycled toner it uses through simulation, don't get carried away though or the system will back up.
