Make the following preparations before disassembling the Stylus PHOTO RX640/650:
When the Main Board is to be replaced, make a copy of the EEPROM data.
When the Carriage Assy is to be moved out of its home position, locate it at a
position other than the home position before starting disassembly by turning the

As soon as the repaired product has been returned to the user, there may be a case

Avoid such a case, if possible, as follows: Check the maintenance counter for
regularly replaced parts before disassembly. If the life of any part is found almost
expired, communicate with the user to that effect. If the user's consent is obtained,
replace also the relevant service parts with new ones.
