Knowledge Data Base ( KDB No.: KB0000005 / Status: Close ) Model: Di620 Problem Machine: Di620 Title: PC Drum Paper Seperator Marks Symptom: Paper Transport / PC Drum wrap around Paper JAM Detection Sensor Symptom Explanation: PC Drum Paper Seperator Marks Notice: PC Drum Paper Seperator Marks is registered as non-supproted matters and it is difficult to solve this problem completely. Therefore in order to reduce the occurance of this problem as much as possible, the following information is offered . 1. Switch the DIP SW "ON or OFF" position in the Image Transfer Separation High Voltage Unit to make the difference between AC output and DC output optimum so that marking of the Separators can be eliminated. [Side Effects] If the difference is adjusted too large, AC mark will be reproduced. [Attention] VR attached in HV is used for rough adjustment in factory, so it is neccesary not to touch it. If marking of the Seperators doesn't disappear by adjusting DIP SW, there is strong possibility that other factors influence greatly .)

Replenish the toner immediately with "Toner Replenisher " after having increased the ATDC control voltage by 0.3v. [Reason] Among the machines, TC ratio tends to be controlled at the lower side within the specified ratio. If TC ratio has decreased to 3.5% or less in such a machine, image stabilization control starts to work to make Vg high, which may result in the lower performance of Seperator. In order to avoid working the image stabilization control, set the TC ratio to the higher side. [Side Effects] Amount of toner consumption: There is no change since the ID is controlled within the specified level thanks to AIDC control. Toner scattering: It is confirmed that the level of toner
