1-6) Turn the inlet roller so that the oil-coated surface is hiding inside the
unit. This is to prevent the coated oil to be scraped by the belt when
the pressure belt is attached.

1) Upload the 'SramDCON.bin' from 'upload the backup data' using SST and
save it.
MEMO:
For detailed uploading procedures, see the chapter of upgrading in the man-
ual.
2) After replacing the DC controller PCB, download the latest system soft-
ware using SST.
3) Execute RAM clear of the DC controller PCB by the service mode below.
COPIER > FUNCTION > CLEAR > DC-CON
4) Select the uploaded file from 'download the backup data' and download it
using SST.
MEMO:
For detailed downloading procedures, see the chapter of upgrading in the
manual.
5) Select the uploaded file from 'download the backup data' and download it
using SST.
6) Remove the waste toner in the waste toner receptacle (waste toner bottle,
secondary transfer outside roller waste toner receptacle), and then clear
the 2 types of waste toner counter (see Note 1).
7) Execute the service mode (high-voltage offset adjustment: COPIER >
FUNCTION > MISC-P > HV-ADOFS) (see Note 2).
8) Execute the service mode (compulsory initial rotation: COPIER > FUNC-
TION > MISC-P-INTR-FX).
9) Execute the full correction of the automatic gradation correction (image
characteristics correction control).
Note 1:
You cannot re-enter the waste toner counter (waste toner bottle, secondary
transfer roller waste toner receptacle) in the service mode. Therefore, in or-
der to replace the DC controller PCB or clear the RAM, clear the 2 types of
the waste toner counter using the following service modes:
- Waste toner bottle counter clear: COPIER > COUNTER > MISC > WST-
TNR
- Secondary transfer outside roller waste toner receptacle counter clear:
COPIER > COUNTER > MISC > 2TC-BOX
Note2:
On execution of this service mode, the waste toner sensor offset adjustment
is executed.
If toner is left inside the waste toner bottle here, toner adjustment cannot be
carried out properly, resulting in an error code in some cases (E0013-0006:
waste toner sensor adjustment error).
Be sure to execute this service mode after removing the waste toner bottle
from the main body.

(1) Before replacing the SRAM PCB, inform the customer that replacing this
PCB will erase the entire image data in the BOX. Continue on the proce-
dure if the customer accepts it.
(2) Replaced SRAM PCB must be brand-new. Placing a used SRAM PCB in
other equipments will cause malfunction.
1) Replace the SRAM PCB with a new PCB, and turn on the main power.
At this point, the system will be automatically initialized.
2) On star-up, a message will be displayed in the panel: "Turn off the power
on the right side of the equipment." Following this instruction, turn off the
power and then restart the equipment.
3) Select the items shown in the diagram in the Service Mode, and then press
Enter. This will clear the RAM.
