2. Appendix 2: Service Program Mode
These SP codes display the length of time that each print head has remained idle
("Leftover"). If a print head remains idle for a long period, this can cause the ink around
the nozzles to dry or become too viscous to produce good quality images. To prevent this
from occurring, the machine automatically executes a maintenance cycle appropriate to
the length of time that the print head has remained idle.
These times are used to determine these operations:
• Print head cleaning and flushing
• Air purging (ink supply, purging, filling/maintenance air purging filling together)
• Ink supply sequence
