Only two options
1) check harness of transfer unit to copier.
2) replace transfer power pack.

Sc 440 is Transfer Output Error



Description
One of the following conditions was detected for 17 counts (about 100 ms) when the transfer voltage was applied with the main motor operating:
• The value for the transfer current was set for 70uA, but the feedback voltage was less than 0.75V (less than 1.5 KV).
• When the feedback current was less than 0.16V (10uA), the feedback voltage was less than 0.15V (less than 300V) due to a poor input connection.
• When the feedback current was less than 0.16V (10uA), the feedback voltage was less than 3.05V (over 6.1 KV) due to a poor output connection

Causes

• Transfer power pack harness, connectors loose or broken
• Transfer power pack harness or connectors have short circuited
• Transfer power pack is defective

check the harness most of the time its cut due to tilting up and down of transfer knob...
