If the customers doing a lot of colour, Canon have estimated a drum life of around 17.5k..

I work on these machines daily, and yep they are a pain, before stripping it all out, check if one of the devs have dumped itself all over. If not, has it in the past and not been cleaned up correctly, remove the drum and check the back of the drum, if its covered in toner , look down where the drum was at the base of the machine, is there toner there, or at the back of the turret, which again you can see through and down where the drum normally sits, another tell sign, the laser cleaning rod , (blue thingy) is the got loads of toner on it. If so then the loose toner is being flicked up by the turret, and im affraid 3 hours strip vac out and clean to stop it. Devs can leak a lot especially the yellow and cyan.
The second if no excess toner is present, the patch sensor although they are a sealed unit they can get toner in it behind the lense, ( i have had a few like this) if nothing else works and its clean, change the patch sensor, The enviroment sensor can fool the system too if this is dirty, why as its totally different but again experience has shown me that these m/c are bitches (it sits next to the patch sensor) If you need more details on problems on 3100 3170 range just message me. Had a lot of time on these suckers.

When cleaning the patch reading sensor,clean the shutter assembly that opens and closes over it also and never use a dry rag to wipe the sensor window...like on clcs this will create static on them and toner will attract to them. Use a super wrung out piece of cloth. The machine as stated looks at the clean drum surface before generating patches. Having a roll for primary charging beats the heck out of the drum surface...like said earlier 4 separate images for full color. So if the drum is not all nice and shiny it doesnt reflect anything back,plus if it is not cleaning properly. Yeah, the tool of choice on these pigs is the vacuum. You can notice on used drum assemblies the cover for the primary roll is always filthy. Toner chugs out from that area right onto the patch sensor. Put a new drum in it,then clean the patch reader assembly

Bro,do you try and check the photo sensor? faced same issue by replaced the sensor.

I just cleaned the sensor with a fine brush and in fact I cleaned the inside of the turret assembly-lots of toner was spilled all over. The machine is working so far but it is very likely the developer is due for replacement as suggested. I have made an order for it but it is taking time to arrive. So be sure to check for loose toner. Regards!

If all fails then change the drum, have you sorted it yet, as plenty of help but no reply to say if any has helped.

All the guys are spot on, but do yourself a favour after you have done cleaning run 40 to 50 PGTYPE 5 s with colours on 255. This will detone dev units. If you dont the units will make the dirty agan and of you go with a vacume. Replacing dev units is ideal but costly.

Hope this helps

If you detone the dev units ATR will just try to replenish them....you can detone them but if you dont re-initialize them the machine will try to tone up to generate satisfactory patches

Just a clearing up of information here.. Canuck imparted lots of good info,,

I would only point out that the sensor he is referring to in the front of his message is not the Patch sensor, but they ATR sensor. ATR looks at the developer mix color saturation, while the Patch sensor looks at toner patches created on the photodrum surface.

Good point about not statically charging the sensor window with a dry cloth!
