When the adjustment value is changed, the image losses at the four 
corners are changed uniformly.
• When the set value is 50 at transfer ON timing, the transfer 
operation is turned on immediately when the paper lead edge 
passes beneath the drum. 
• When the set value is 50 at transfer OFF timing, the transfer 
operation is turned off immediately when the paper rear edge 
passes beneath the drum.
• When the transfer ON/OFF timing value is decreased, the transfer 
ON/OFF timing is advanced for the paper. 
• When the transfer ON/OFF timing value is increased, the transfer 
ON/OFF timing is delayed for the paper.
• Change of ±1 corresponds to about 10ms. The set range is –490 to 
+490ms
