When printing the CDR, the CDR Tray feed amount is adjusted
C A U T I O N
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
(p.153).)
