E196 0302 Title EEPROM communication error
Description Although write polling to the PCRG_M EEPROM from the DC Controller
PCB (CPU) was performed for 3 times, no response was received and
timeout occurred.
Remedy [Related parts]
• Drum Unit (M) (Unit of replacement: DEVE_UNIT_M)
• Front Cover/Right Cover
• Interlock Switch 1 and 2 (Unit of replacement: COVER, INNER, FRONT,
RIGHT)
• Harness between the Interlock Switch 1 and 2 (SW02 and SW03) and
the DC Controller PCB (UN04/J24/1-pin and 2-pin) (Unit of replacement:
COVER, INNER, FRONT, RIGHT)
• Drum Unit Memory PCB (M) (UN13) (Unit of replacement: DEVE_UNIT_
M)
• Drum Unit Relay PCB (M) (UN09) (Unit of replacement: PROCESS
CONTROL PCB ASS'Y)
• Harness between the DC Controller PCB (UN04/J160) and the Drum
Unit Relay PCB (M) (UN09/J6002) (Unit of replacement: PROCESS
CONTROL PCB ASS'Y)
• DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER
PCB ASSEMBLY)
• Harness between the Low-voltage Power Supply PCB (UN01/J315
and J322) and the DC Controller PCB (UN04/J20 and J22) (Unit of
replacement: CABLE, PANEL POWER SUPPLY)
• Low-voltage Power Supply PCB (UN01) (Unit of replacement: POWER
SUPPLY ASSEMBLY)
[Points to note at work] When checking the harness/cable or connector,
perform the following work.
1. Disconnect and then connect the connector to check that there is no
bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.
3. If there is any error, replace the corresponding harness/cable.

Remedy [Remedy] Perform the following in the order while checking whether the
error is cleared.
1. Remove and then install the Drum Unit (M), and check whether the error
is cleared.
[Reference] EEPROMs on the Drum Units of all colors are connected each
other with signal cables. Therefore, even if the error is not cleared with
step 1, it may be cleared by removing and then installing the Drum Units of
all colors.
2. Check that the Front Cover/Right Cover is closed.
3. Visually check that the Interlock Switch 1 and 2 are turned ON/OFF by
opening/closing the Front Cover/Right Cover.
4. Turn OFF and then ON the main power, and check whether the error is
cleared.
5. Check that the harness between the Interlock Switch 1 and 2 and the
DC Controller PCB is not short-circuited (the harness does not come in
contact with the plate while the cable sheath is peeled).
6. Check if the Drum Unit Memory PCB (M) and the Drum Unit Relay PCB
(M) are damaged or deformed, and replace the Drum Unit (M) if necessary.
7. Check if the Drum Unit Memory PCB (M) and the Drum Unit Relay PCB
(M) are soiled. If it is soiled, clean it with a blower.
8. Disconnect the connector (J24) of the DC Controller while the Front
Cover and the Right Cover are closed, and measure the resistance value
between the connectors J24/1-pin and the J24/2-pin on the J24 harness
side using a tester.
a. If the measurement value is less than 1 ohm (conduction state),
1. Replace the DC Controller PCB.
2. Replace the Low-voltage Power Supply PCB.
b. If the measurement value is 1 ohm or higher (non conduction state),
replace the harness between the Interlock Switch 1 and 2 and the DC
Controller PCB.
9. Check the harness between the Low-voltage Power Supply PCB and
the DC Controller PCB.
10. Replace the DC Controller PCB.
11. Replace the Low-voltage Power Supply PCB.
E196 030F Title EEPROM communication error
Description The number of read/write job data to the PCRG_M EEPROM (device
information) exceeded 100.
Remedy [Remedy] Turn OFF and then ON the main power.
[Reference] Data (device information) is reset by turning OFF and then ON
the main power.
