Technical Bulletin No. RTB-001 SUBJECT: Dirty Background After Power up DATE:August 31, ’95 PAGE: 1 of 2 PREPARED BY: M. Mimura CHECKED BY: FROM: 2nd Technical Support Section CLASSIFICATION: Action Required Troubleshooting Retrofit Information Revision of service manual Information only Other MODEL: Thunderbird II During our on-going laboratory test, we observed a symptom which may occur in the field as the MIF grows. The following describes the details of the problem and the action to be taken. < Symptom > Dirty background on the initial one to five copies after the five minute fusing idling after power on. < Cause > When the oil supply roller is not hot enough just after the fusing idle mode (cold start), the paper dust (colored black as it is mixed with toner) on the oil supply roller moves to the hot roller and accumulates. This paper dust sticks onto the paper, giving the copy dirty background. This symptom tends to occur with paper containing more calcium carbonate after more than 50K copies usage of the oil supply roller. < Objective Units > The units with the following serial numbers have SP 10 4-3 set to SET at the factory.
