Slide 266
Image Position Correction (MUSIC)
When is MUSIC done? (2)
When one of the events on the previous slide occurs, the
use of MUSIC also depends on temperature readings in the
machine at the following locations.
K laser thermistor
M laser thermistor
Y thermistor
ITB speed sensor thermistor
At the start of any one of the events mentioned above, two
judgments are made:
Judgment 1: If the temperature at any of the thermistors has
changed less than a certain amount (set by SP codes)
since the previous execution, MUSIC is done one time.
Judgment 2: If the temperature at any of the thermistors has
changed more than a certain amount (set by SP codes)
since the previous execution, MUSIC is done two times.
The temperature readings are stored in display SP codes: CK laser thermistor
(SP2180-10), YM laser thermistor (SP2180-12), Y (SP2180-15), and ITB speed
sensor thermistor (SP2180-16).
