C A U T I O N

When printing the CDR, the CDR Tray feed amount is adjusted

with compensation considering the deterioration of the CDR Tray,

and the correction level is determined by the number of printed

CDRs. If the data on the EEPROM can not be copied when

replacing the Main Board, banding may occur while printing CDR

due to improper corrections caused because the data of the number

of printed CDRs can not be transferred.

When this happens, replace the CDR Tray Assy with a new one

together with the Main Board. (See

"4.2.5.9 CDR Tray Assy"

(p.153).)
