1 Erase Lamp/Lens
Assembly
Check the erase lamp lens for any
signs of toner, paper dust or other
types of contamination. Clean the
lens with a soft dry cloth if
necessary. If unable to clean the
contamination off the lens, replace
the lens and lamp assembly. Check
the erase lamp assembly. Use the
same procedure as outlined in the
“Erase Lamp Service Check” on
page 2-46.
2 Printhead The printhead on the Optra S
printers cannot be cleaned. Try
another printhead if all other
attempts fail to correct a background
problem.
3 Transfer Roll Assembly Check the high voltage contact from
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.
4 High Voltage Contacts Check the high voltage contacts on
the right side frame to ensure they
are clean and not bent, deformed, or
pitted. If incorrect, replace the
contact.
