Canon IR2800, IR3300, IR2200 manual E248, E261

CHAPTER 6 SELF DIAGNOSIS

E248

0001	A difference is discovered between the ID in EEPROM read when the main
	power switch is turned on and the ID in ROM upon comparison.
0002	The data read does not match the data written to EEPROM.
0003	A difference is discovered between the ID of EEPROM and the ID of ROM
	upon comparison while writing data.
Main cause	The EEPROM (IC403) of the reader controller PCB is faulty. The reader
	controller PCB is faulty.

Action

1.Execute the following in service mode: COPIER>FUNCTION>CLEAR>CON. Is the proem corrected?

YES: End. After executing the service mode, be sure to enter the service mode data newly.

2.EE-PROM, Reader controller PCB

Try replacing the EE-PROM. Is the problem corrected?

YES: End. After replacement, be sure to enter the service mode data newly.

NO: Replace the rear controller PCB. After replacement, be sure to en- ter the service mode date newly.

E261

0000	The intervals of zero-cross signals deviate from the tolerance range while
	the fixing heater is supplied with power.
Main cause	The wiring is faulty (short circuit, open circuit). The main power supply
	PCB is faulty. The DC controller PCB is faulty.

Making Corrections

1. Connectors

Are the connector J205 on the main power supply PCB and the connector J308B on the DC controller PCB securely connected? (zero-cross signal: J205-7 <-> J308B-1)

NO: Connect the connectors securely.

2. Main power supply PCB, Main controller PCB

Try replacing the main power supply PCB. Is the problem corrected? YES: End.

NO: Replace the DC controller PCB.
