(adjustment pattern) printed in the procedure 2) on the docu-
ment table. Place the gray patch image so that the fine lines

NOTE: The  adjustment  result  becomes  valid  only  when  the

both adjustments in the copy mode and in the printer
mode  are  completed.  For  example,  if  the  copy  gray
balance  adjustment  (automatic  adjustment)  is  per-
formed and the simulation is canceled, the adjustment
result is invalid.

11) Check the copy gray balance and density. 
12) Check the printer gray balance and density. 

(Refer  to  the  item  of  the  printer  gray  balance  and  density
check.) If a satisfactory result on the gray balance and the den-
sity is not obtained with the automatic adjustment, execute the
manual adjustment (SIM 67-25) (ADJ 11E (2)). Also when the
service target is selected in procedure 7) to execute the auto-
matic adjustment and a satisfactory result is not obtained, per-
form the manual gray balance adjustment (ADJ 11E (2)). If the
gray  balance  or  density  is  not  in  the  satisfactory  level  even
after  execution  of  the  automatic  and  manual  adjustments,
there may be another cause. Troubleshoot the cause, repair or
perform necessary works, and repeat the adjustment from the
beginning.
