CHAPTER 4 TROUBLESHOOTING IMAGE FAULTS/MALFUNCTIONS
4-2
1.4 Charging Roller and Static Eliminator
1. Check the transfer charging roller and the separation static eliminator for dirt and a fault
(damage).
2. Check to make sure that the transfer charging roller and the separation static eliminator
are correctly mounted.
1.5 Checking the Developing Assembly
1. Check to make sure that the members on both ends of the drum are in contact. Other-
wise, light images can result.
2. Check to see the surface of the developing cylinder is coated with an even layer of toner.
Otherwise, light images or uneven density can result.
1.6 Checking the Paper
1. Check to see if the paper used is of a recommended type. Advise the user that paper not
of a recommended type may fail to bring about expected results.
2. Check to see if the paper is moist. Moist paper can adversely affect transfer, causing
poor images or separation faults (leading to jams and wrinkles). Advise the user on the
correct method of storing paper.
1.7 Checking the Periodically Replaced Parts
Check with the scheduled servicing chart and the table of periodically replaced parts. Re-
place parts that have reached the ends of their lives.
1.8 Image Adjustment Basic Procedure
If the copies have uneven density (difference between front and rear), light images, or
foggy background, try the Image Adjustment Basic Procedure first to see if the problem is
corrected.
