the HVPS to the transfer roll. Check
the transfer arm assembly right side
bearing for any signs of
contamination, pitting or a loose
cable to the bearing. If any problems
are found, replace the defective part.
Check the transfer roll shaft for any
signs of contamination, wear or
pitting on the ends of the shaft that
go into the bearings. If a problem is
found, clean the ends of the shaft or
replace the transfer roll assembly.

the right side frame to ensure they
are clean and not bent, deformed, or
pitted. If incorrect, replace the
contact.
