2. Appendix 2: Service Program Mode
This SP adjusts the threshold for the tank full alert for the left ink sump at the far left side
of the machine.
• The left ink sump has no ID chip.
• Changing this SP setting changes the threshold value stored in NVRAM.
[1 to 800/500/1 ml]
6 Waste Ink Box: Left Near Full Threshold
This SP adjusts the threshold for the tank near-full alert for the left ink sump at the far left
side of the machine.
• The left ink sump has no ID chip.
• Changing this SP setting changes the threshold value stored in NVRAM.
[1 to 100/85/1 %]
2510 Flushing Magnification DFU
The SP adjusts the amount of ink that is purged from the ink heads at the beginning of a
print job. Increasing the number of drops purged before printing, prevents image
streaking. Consider raising this setting in an environment where the print heads may
have a tendency to dry out:
• If the machine is remaining idle for long periods.
• Where the ambient humidity is low.
• When the machine is switching infrequently between monochrome and color
[1 to 20/1/0.1]
2513 Mainten. after Leftover Thresh` DFU
Even with the print heads capped, if the machine remains idle for a long period, this can
cause the ink around the nozzles to dry slightly and become too viscous to produce
good quality images. To prevent this, the machine will execute a maintenance cycle
appropriate for the length of time that the machine has remained idle. This is done
automatically without intervention by the operator after the machine is turned on, or after
a print head has not been used for a long period of time.
These SP codes allow you to set the threshold settings that trigger SP2520 and SP2521:
• SP2520 - Maintenance On/Off Switch
• SP2521 - Number of maintenance cycle repetitions
