[CQ] w2400 dark copies and prints

[acsolutions]

Hello, the w2400 I'm working on had lots of toner built up on the charge assy. on one side only as well as a slight background on the entire print.
I cleaned up the machine and ran it, looked ok then three weeks later customer calls back with the same problem. This is the first time I had seen this machine and I did not know what had been done to it previously. I check the history and saw the charge assy. ID sensor and the developer powder had been replaced within the last 6 months, I could not tell what was causing the charge to get so much toner on it so quickly! I was thinking of replacing the developer again and the seal above the mag roller, I hear this can cause the issue. The customer also said they go through a lot of toner, I'm not sure if it's pulling excessive toner due to calibration! the back grounding had been compensated by adjusting the dev. bias in the service mode. The copies were still a bit weak but customer says this was the best they ever looked. All the toner is leaking on one side. I check to see if the machine was level,OK! when I pulled the toner tube there seems to be more toner and developer on one side. The toner seems to be OEM. Thanks, any suggestions would be great!

we have a lot of this machine in the field, replace the developer first but dont put the toner after initializing it, make a test copy without the toner.in this way you can isolate if there is a problem on the toner.

Hey thanks for the response. Sorry the machine is a W470 Ricoh. Is there anything else I should look for ? This machine is 100 miles away and I would like to be prepared before returning. Definitely I will take developer And would like to know what can cause that leaking on that one side and not anywhere else!
About 8inches on right side and saturating the charge corona on the right side?

visually inspect the cleaning entrance seal,there should be no gap between the drum. also check the waste toner collection unit, sometimes the collection coil( 20 AD04 3068 Toner Collection Coil - Cleaning) can't move the toner to the waste toner bottle.

Good points, the last guy replaced the cleaning case, spring auger and developer maybe they are bad out of the box! Sometimes I think all new parts are never bad!!
I'll take those items with me next time I go up! If you can think of anything else that would be great! Thanks again!!!
