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!

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.

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

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..

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!

I am talking about patch sensor...when you pull the drum unit out its at the top left hand side. This is what is used to look at the drum surface. It has a shutter similar to the ATR sensor,but it compensates for soiling,whereas the ATR sensor doesnt. The ATR shutter is only open when its looking at the cylinders. The xx81 code is generated by the patch image sensor,not the ATR sensor

machine checks the patch image read sensor for soiling. While initial multiple rotation is under way, the machine measures the light from the surface of the drum without depositing any toner on it (drum background measurement); it will assume that the window is soiled if the measurement is lower than a specified level (COPIER>DISPLAY>DENS>P-SENS-P> optimum range: 400~600), thus indicating an error code (E020-0081) and stopping its operation.
simple fix/ just replace the drums/probably are old if error returns this fast/u can also replace the Image Patch Sensor if old

Maybe they build them differently for you in Canada, but mine have no such shutter over the patch sensor. It is sitting under that shield, exposed all the time to the drum. No shutter in its optical path.

I think its the same design where ever..the patch sensor on the drum has no shutter. The atr sensor has a shutter and reads the toner / dev ratio on the dev cylinder.

My mistake....its just a cover over the patch image sensor...havent dealt with these machines in a while and i never have a manual with me when i'm on here....we flipped all our 3100 series years ago....junk...baby 6800

Another fix for low P-SENS-P readings is to peel off the face plate from the Patch Sensor. It's just a peel-able transparent piece of tape, which seems to serve no purpose other than to get scratched (from repeated cleaning) or covered in toner from the drum/devs. Removing the tape will immediately increase the value of P-SENS-P and reduce the frequency of E20-0081 errors.

[teckat]

removing that tape will not prevent E020-0081 errors/
if fact it will happen more often/ to keep the P-SENS cln, requires good maintenance on the machine & replace parts on a usage schedule

Same disappointment, in a smaller package...

[Dan Dryer]

Simply untrue. This is a tried and tested repair method which dramatically decreases the frequency of E20-0081 errors. The error occurs when the tape gets covered in toner. The sensor itself is set back in the housing and less likely to be covered by toner, even after the tape is removed.

[teckat]

what is to prevent toner from getting in the housing ??
what about maintaining a PM sch. ??
