Sharp MX-b402 print quality

[tibbs]

Hello, I have a Mx-b402 that's printing light and on the left side of the paper I have replaced the drum and the toner but I am having the same issue.
Also I have serviced and cleaned the machine.

Thanks for any help.

Prints only?

Have you tried cleaning the LSU window? You changed the drum, what about developer? Is your Transfer roller worn?

Pull the IT belt unit and look at the cam. This machine is notorious for the plastic frame breaking and causing this exact same issue...
Also, check the fuser pressure is even.

I would check all the other suggestions first, but I have had the LSU do this.

I second this. Mojorolla is absolutely right about the Primary Transfer. I've seen that cam break quite a few times before too.

Have had too many primary transfer belt units cause this even when they appear to be good!!!!!
