This RTB has been issued to announce the following three notes and a correction of the
TCRU manual regarding the procedure for re-installing the drum cleaning unit.
These notes are important in preventing SC39x (drum motor errors) and the image quality
issue known as in-track lines.
Note 1: Always replace the drum lubrication bar and drum lubrication
roller as a set.
Make sure that the drum lubrication bar and drum lubrication roller are always
replaced as a set, whether the replacements take place for PM or EM. A worn roller
can cause unsatisfactory lubrication even if the lubrication bar is new, and vice versa.
