17. Discard the empty bottles.
Obey local laws and regulations concerning the disposal of items such as the
empty bottles.
18. Reattach the toner hopper.
19. Open the front door [A].
You must open the front door.
Turning on the machine with the front door open prevents the machine from
performing the initial process control self-check.
If the front door is closed, the drums will start rotating with no toner in the
PCUs.
If the drums rotate with no toner in the PCUs, this can cause the cleaning
blades to catch on a dry drum and damage the drum surface.
20. With the front door open, turn on the main power switch.
21. Do the SPs that are indicated by the table in the 'SP Codes after Replacements'
section.
If you add developer at the same time as you install a new PCU, do SP3010,
3011, 3012, or 3013 before you initialize the developer.
Handling Problems with Developer Filling
Procedure 1
Do this procedure first.
The most common cause of an SP3815 error is failure to remove the tape from one of the
bottles. If you see any number other than "1" after doing SP3815:
1. Note the position of the digit where the number is displayed. For example, If the
displays reads "1191" the problem occurred at the C PCU.
2. Check the attachment of the bottle at the affected PCU and make sure that the tape
was removed.
3. If the tape has been removed, do Procedure 2
Procedure 2
Do this procedure only after you have done Procedure 1 immediately above.
If all tapes have been removed but developer remains in one or more bottles, do the
procedure below.
1. Do SP3814-1 to 6 for the color of whichever PCU is to be filled with developer..
