6)
Re-enter the FU UNIT (NC8) value as follows;
i) Enter the value of NC8 - LP8 into the TOTAL PAGE counter.
(i.e.) NC8 - LP8 = 39,684 - 70,000 = - 30,316
Since the above result is minus, reduce the value of LP8 is 30,000P in order to
make the result plus, then enter it into the LIFE PERIOD SET counter in
FACTORY MODE.
The formula is as follows;
NC8 - LP8 = 39,684 - 30,000 = 9,684
Enter the value ‘9,684’ in TOTAL PAGE.
ii) Perform CLEAR CARE 8. (Refer to ‘36 CLEAR CARE’ in page V-24 of Chapter V.)
iii) Check that the value of NEXT CARE is reset correctly.
(i.e.) NC8 = 39,684P
iv) Reset the LIFE PERIOD counter in FACTORY MODE to 60,100.
7)
Re-enter the 240K KIT (NC10) value as follows;
i) Enter the value of NC10 - LP10 into the TOTAL PAGE counter.
(i.e.) NC9 - LP9 = 120,000 - 120,000 = 0
Enter the value ‘0’ into the TOTAL PAGE counter.
ii) Perform CLEAR CARE 9. (Refer to ‘36 CLEAR CARE’ in page V-24 of Chapter V.)
iii) Check that the value of NEXT CARE is reset correctly.
(i.e.) NC10 = 120,000P

MODE.
(i.e.)
T = 412P
9)
Re-enter the original EACH IMAGE (IY, IM, IC, IK) values in EACH IMAGE SET in
FACTORY MODE.
(i.e.)
(IY)=348P, (IM)=353P, (IC)=365P, (IK)=439P

Ensure that the values in the LIFE PERIOD SET counters in FACTORY MODE are
correct.
(i.e.)
FC ROLL (LP2)=12,000P
BL UNIT (LP7)=50,000P
