1. Model Name:
AR235/275
2. Description:
The AR-235 / 275’s MCU PWB contains information specific to the copier, including the
Serial number and test command data. If the MCU PWB fails and is subsequently
replaced, this data will be lost.
3. Action:
IC105 (MCU PWB) is an EEPROM device in which the above listed information is stored,
so it is important to ensure when exchanging the MCU PWB that this IC is removed and
placed in to the new PWB. In this way, the Serial number will be intact and new product
codes (for installed options) will not be required. If the PWB is to be replaced within the
12-month warranty period, exchange IC105 between both boards before returning the
faulty MCU PWB, otherwise retain the IC after discarding the faulty PWB. Care should be
taken whilst handling static-sensitive devices.
Note that in the event of an all clear being performed on the machine, the data will be lost.
