Lexmark C780 100.01 error

[tufbnme]

This is a new out of the box printer a customer bought at a garage sale and keeps throwing this code. The transfer belt is covered with toner (all colors). I removed the belt and transfer roller, cleaned them and still get code. Very unfamiliar with this unit. Is it worth repairing? any Ideas

MORE THAN LIKE IT IS THE FIRST ONE ON THE LIST, ESPECIALLY SINCE YOU SAID IT WAS NEW OUT OF THE BOX

1 Make sure all packing material is removed from the
printer. The detensioner is located underneath the
toner cartridges. Make sure the ITU detensioner is
removed. Remove the detensioner by pulling up on the
red handle on the right side of the ITU.
Note: All the print cartridges must be removed to gain
access to the detensioner packing material.
Has all packing material been removed from the
printer?
Go to step 2 Remove any
remaining
packing material
from the printer

2 Check the ITU release lever for correct operation. The
ITU release lever is the black lever located on the left
upper side frame above the ITU opening and can be
seen by opening and lowering the MPF assembly.
When locked, the lever should be at the 6 o'clock
position. When unlocked, it should be in a 3 o'clock
position. Undue pressure is not required to operate the
lever.
Does the ITU release lever operate correctly?
Go to step 3 Repair as
necessary.

3 Check the second transfer roll installation.
Is it installed correctly?
Go to step 4 Reinstall the
second transfer
roll.
