Explanation of Fuzzy Lines
The symptom known as "fuzzy lines" is a result of insufficient supply of toner/developer
mixture to the drum surface via the development rollers.
Photos A and B below show the slit between the upper and lower development rollers
viewed from the drum.
Photo A: The "fuzzy" condition of the toner/developer mixture is reflected directly to
the output, generating the fuzzy lines.
Photo B: The mixture is solid and generates proper output.
