Carriage Stopping Accuracy calibration
Purpose
This calibration adjusts and calibrates the stopping accuracy of the print carriage motors.
When to run
Run this calibration in the following situations:
● A carriage or carriage-related part (such as a carriage motor) is replaced.
●
A warning message is recorded in the event log indicating a carriage accuracy issue.
●
When directed to in order to fix a print-quality problem.
Required time
8 to 30 minutes
Internal operation
The Carriage Stopping Accuracy calibration begins with a diagnostic of the Carriage 1 stopping
accuracy. This diagnostic section is used to quickly determine if a more lengthy calibration is
required. The carriage performs a stopping accuracy test in three zones along the carriage travel
axis. After all three zones are tested, the actual calibration process automatically runs only in the
zones that failed.
After Carriage 1 is completed, Carriage 2 begins the same process.
After the testing and calibration are completed, the new carriage stopping data is stored in NVM.
A warning message is recorded in the event log if a carriage deviates from the expected carriage
stopping behavior profile.
Based on the carriage-stopping profile, carriage motor speeds are adjusted to slow down and stop
the carriages at precise locations.

Carriage encoder strip adjustment
Purpose
Carriage 1 and carriage 2 encoder strips need to be adjusted (centered) at the front and rear of
the carriage travel for correct positioning to be read by the index sensors on the pocketboards.
