KM 3035-5035 blacks not dense enough, (dirty laser?)

first thing is first did you clean out the filter in the bypass section? The reason i asked is the heat builds up and messes with your fuser,drum,dv unit. The dv unit will get hot and melt the toner on to the cleaning blade and build up and cause the dv unit to put a very thin layer on it and will cause light prints. Just get a piece of paper and place on the cleaning blade turn the roller the backwards till the paper goes in. When the paper is inside move it from side to side until clear. If the paper gets stuck reverse the roller again and try again. This should get it done if this is the issue. as far as cleaning the roller if it has lines use just a green cleaning pad and wipe with dry cloth.

If the copies are just a little light rather than changing out a drum right away I adjust background in the copy defaults.

This all seems great advice but have you tried a "drum refresh"? i sometimes find this will bring back the density to a decent level but obviously depends on how faded your copies are

Okay, I'm factory trained on this one (the hard way-over the phone with tech. support, we had one, and I loved it, except for the plastic drum cover in the maint kit-BE CAREFUL!!)
I would bet one of the previous posters may be right with transfer roller (1) and mag roller (2) BUT i'd bet that the starter/developer inside the unit has died of OLD AGE. Why? You say they're all 3 years old, but the maint. cycle on the 5035 is 400K prints!!! Yeah!!
So, you've gotta be looking at one of those 3, but if i was a betting man, I'd say my answer should be #1 most likely. What say the rest of you guys??
I've been techin' for 22+ yrs.

I would go with the developer... (2)

Check to make sure that the laser power is set correct for the model you have. I think that it is sim 274. Check your manual.
