If it is caused by PH unit, Exchange PH unit. 2. Photocon Trouble uuuu - several color appear 1. Exchange Transfer belt unit2. Check the inside of a waste toner pipe. If the toner pipe is blocked by waste toner, break blocked toner into fragments. And clean toner pipe inside.3. When waste toner is much in waste toner box, inform user to exchange waste toner box. When the waste toner is blocked in the cleaner of Transfer belt unit and the waste toner pipe, it is not possible to exhaust it normally. The pattern for the image stabilization control cant be normally drawn on the transfer belt. As a result, Photocon Trouble uuuu is appeared. One case with waste toner blocking. Though the message of the exchange of waste toner box was displayed, user kept using waste toner box with shaking. As the result, the waste toner was not able to be exhausted normally. See left column Go to Step 6 6 Exchange the following parts when not repairing to step 5.1. High voltage unit2. Mechanical Control Board Exchange board End Table 3-19.
