1 After replacing the developer, be sure that you do not make any copies until you have first carried out L
detection adjustment.
*
2 When PRMB (Parameter memory board) is replaced, remember to replaced the developer before con-
ducting the L deection adjustment.
Note:
• When replacing a board due to the SCB (System control board) being damaged, the PRMB (Parameter
memory board) that was installed on the damaged SCB should be used as a rule on the new SCB.
The use of a new PRMB should be limited only when it is considered that the PRMB is also damaged.
On this occasion, adjustment data have not been input into the new PRMB and it is necessary to imple-
ment all of the adjustment items. In order to make the new PRMB effective, the 47 mode - 92 (output)
should be carried out before implementation of the adjustment items.
• When the adjustment items have been implemented, the 47 mode - 96 (output) should be also executed.
The adjustment data are backed up by implementing the 47-96 mode.
For the original PRMB installed on the damaged SCB, the 47-92 mode is protected against inadvertent
execution. For details of the cancellation of protection, contact the service manager of the authorized dis-
tributor.
