To prevent uneven images in transparency mode, two seals are added to change the air flow from the fusing unit.
This is because the silicon gas from the fu sing unit makes the charge wire dirty.

It was reported that a few thousa nd copies after installation, vertical white lines start to appear on the cop ies. This
especially happens in the half tone are a of the 1st cop y. This problem is caused by toner particles accu mula ting on the
cleaning blade edge during the cop y run. To minimize the vertical white lines on the 1st copy, the transp ort and main

It was reported that separa tio n jams (03) are sometimes detected when options (sorter, ADF, duplex unit) are
installed on the SP50. This is becau se sensor on timing in the software is delayed from the actual sensor on time
when an option is installed. If the sen sor on timing in the software is later than the jam det ect ion timing , a pa per ja m
is detected. The occurrence ratio is highe r if more op tio ns are installed.
To counter this, the jam detection timing in the software has been changed.
