Auto-calibration.
■ When to perform auto-calibration

□ After replacing the IMM
■ Why perform auto-calibration
The jet speed control ensures print quality over time. The control depends on the ink
type and several printer components (such as the printing module and the ink
management module).
Once the printer is assembled and loaded with ink, the auto-calibration procedure
calibrates the control system.
■ Performing auto-calibration
After checking the installation parameters (head height difference), calibrate using ink
with the appropriate concentration.
When the jet reaches its rated speed, the auto-calibration validation positions the curve
Pressure = f(Temperature).
■ Procedure
Printer empty and stopped.
Connect a new ink cartridge at the same temperature as the printer.
Remove the additive cartridge.
Start the printer (faults 51 and 53 appear).
Check or enter the head height difference and ink type parameters.
WARNING:
The head height difference must match the actual difference during
auto-calibration.
REMINDER:
the head height difference is the distance between the middle of the
head and the middle of the console.
NOTE:
If the head is not at the auto-calibration position when the head is placed in
the working position, the head height difference must be
changed and adjusted.
