5.2 Adjustment After Replacing Parts
The following describes the adjustments necessary when replacing parts.
Color drift adjustment and correction is constantly necessary.
5.2.1 Precautions when Replacing the Engine Control PCB
When replacing the Engine Control PCB (SV2 PWB) remove the EEPROM from the old PCB.
Then mount it on the new PCB. (For Error other than Engine EEPROM Error)
If on the Operation Panel, a “SERVICE CALL XXX (Engine EEPROM Error)” is displayed, replace
with new EEPROM. In this case execute the procedures described in Section 5.2.2.
For ODA version
Be careful to change the engine-control substrate (S2V PWB) of 600 dpi device due to different
substrate to change based on a destination (due to different version of PU-FW).
Sta
ndard devide: S2V-11
Specified destination (for AB): S2V 18
5.2.2 Precautions Upon EEPROM Replacement
When replacing the Engine Control PCB (SV2 PWB), if the EEPROM was removed but not
mounted on the new PCB, or if the EEPROM is replaced with a new EEPROM, then the Version
Read Function (Fuse Cut) has become invalid. For this reason, there is a need to use the PJL
command to switch the Factory Mode to the Shipping Mode to activate the new EEPROM.
[Details]
1. T
o set the Shipping Mode, send the applicable PJL File to the printer.
2. To apply the setting, restart the printer or send a reboot command (PJL File) to the
printer.
[Procedure]
Exe
cute the following procedures from the MS-DOS prompt.
1. Copy/b Pjl_ship.bin prn
2. Copy/b Pjl_reboot.bin prn
or Turn OFF/ON power source.
[Necessary PjlFile]
1. P
jl_ship.bin
2. Pjl_reboot.bin
Replacement Parts Adjustment Details
LED head Unnecessary
Drum Cartridge (Y, M, C, K) Unnecessary
Fuser Unit Unnecessary
Belt Cassette Assy Unnecessary
PU (S2V PCB) Assemble EEPROM used with the PCB before it was replaced. *Note 1
CU (1200dpi:
AS3 PCB)
A
ssemble EEPROM, HDD, Keychip (used with the PCB before it was
replaced.)
*Note 2
CU (600dpi: TBX PCB) Assemble EEPROM used with the PCB before it was replace *Note 3
Paper Thickness Sensor Assy
Paper Thickness Detection Sensitivity Correction and Media Thickness
Detection Value Test
*Note 1 : When using a new EEPROM for the PU (S2V PCB), the paper thickness detection sensitivity shall be corrected.
*Note 2 : When replacing the CU board, HDD, or EEPROM of the 1200-dpi system, follow the instructions given in the
annexed table.
*Note 3 : When a new EEPROM is used for the CU board of 600 dpi system, adjust it to customers setting. It the customer
has registered files in the Flash, restore them (Form overlay and the like).
