So my 1st question here is what methods have you taken that have successfully worked in this scenario looking for something a little bit more permanent then just force toner, below is an example of the black density change with Its color chart number.

Try changing TDC sensor

Try changing TDC sensor

I will try that but is it not to soon to be doing that? I mean one machine has only 8k on it.

[scepter2112]

yes that is weird. But so is copy quality dropping off. There was also problem with Charge roller on other models.

Have you tried reducing the value (pages) in SP3102? If your customer is doing full coverage all the time, change the value to 1 or 2.

This problem is not only with this model. All new BW models like 6000SP or 6001 have exactly the same problem. Black is fading out after 20 ~ 40 K depends on the coverage. Replacing TD on 6000 didn't help, we have many units with this issue and in my own opinion is caused by a developer production problem combined with the customer's environment (coverage). SP 3102 could help in many of those situations, because forced toner is not a good solution for 6000. Ricoh released new firmware which address this problem, even is not mentioned...they mention it only for one firmware release but every new firmware addresses this problem.
