4-6-5-1 Signs and Measures at Poor toner cartridge
Fault Light image and partially blank image (The life is ended.) Signs � The printed image is light or unclean and untidy. � Some part of the image is not printed. � Periodically a noise as "tick tick" occurs. Cause & Check 1. If the image is light or unclean and untidy printed image - Shake the developer and then recheck. (1)NG: Check the weight of the developer (2)OK: Lack of toner, so the life is nearly closed. 2. Some part of image is not printed - Shake the developer and then recheck. (1)NG: Check the weight of the developer and clean the LSU window with a cotton swab, then recheck. (2)OK: Lack of toner, so the life is nearly closed. 3. Periodically a noise as "tick tick" occurs - Measure the cycle and the weight of the developer. Solution 1. All of 1, 2, 3 aboveIf it become better by shaking, replace with a new developer after 50-100 sheets in the closing state of the life span.

2. In case of 2If it becomes better after cleaning the LSU window, then the developer is normal. (Because of foreign substance on the LSU window, the image has not been printed partly.)
3. In case of 3If the cycle of noise is about 2 seconds, the toner inside the developer has been nearly exhausted.( Purchase and replace with a new developer after using about 200 sheets at the point of occurrence)
4. White vertical stripes on the whole screen or partly : Check the weight of the developer.
4. In case of 3This is a phenomenon caused by lack of toner, so replace with a new developer.
Toner Contamination
� Toner is fallen on the papers periodically. � Contaminated with toner on prints partly or over the whole surface.
1. Toner is fallen on the paper periodically. (1)Check the cycle of the falling of the toner. (2)Check the appearance of both ends of the developer OPC drum. 2.The center of the printed matter is contaminated with toner. (1)Check whether foreign substances or toner are stuck to the terminal (contact point) of the developer. (2)Check whether the state of the terminal assembly is normal.
1. If both ends of the OPC drum are contaminated with toner: Check the life of the developer.
