2. Appendix 2: Service Program Mode
These SP codes set a timer to restrict this operation. If the time does not elapse, then the
maintenance cycle or time of cleaning (cleaning or flushing) does not execute. Also, you
can set a temperature to be applied to the same time interval. If the temperature does
not deviate more than this setting during the same time period, then operation is not
done. These SP codes prevent the repetition of maintenance cycles.
1 Printing Standby Time
This setting writes over the exit time of the most recent paper feed. The machine uses this
setting for the start time of maintenance after idle time.

2 Last Maintenance Time H1
This SP codes sets a time interval for the execution of the most recent maintenance cycle
for H1 (K1). If this time interval has not elapsed when the machine is powered on, or
after it has remained idle, then the maintenance cycle is not done. This prevents useless
duplication of the cleaning cycle for H1 (K1).
[0 to 4294967295/0/1 sec]
3 Last Maintenance Time H2
This SP codes sets a time interval for the execution of the most recent maintenance cycle
for H2 (K2). If this time interval has not elapsed when the machine is powered, or after it
has remained idle, then the maintenance cycle is not done. This prevents useless
duplication of the cleaning cycle for H2 (K2)..
[0 to 4294967295/0/1 sec]
4 Last Maintenance Time H3
This SP codes sets a time interval for the execution of the most recent maintenance cycle
for H3 (C). If this time interval has not elapsed when the machine is powered on, or after
it has remained idle, then the maintenance cycle is not done. This prevents useless
duplication of the cleaning cycle for H3 (C).
[0 to 4294967295/0/1 sec]
5 Last Maintenance Time H4
This SP codes sets a time interval for the execution of the most recent maintenance cycle
for H4 (YM). If this time interval has not elapsed when the machine is powered on, or
after it has remained idle, then the maintenance cycle is not done. This prevents useless
duplication of the cleaning cycle for H4 (YM).
