flash at a 1 second rate.
This is a fatal error.

Troubleshooting a fatal error

Use this sequence to follow the startup procedure and try to determine which item might be failing.
The last step completed before getting the fatal error is where the error occurred. This is where
you should look to determine what in the above table should be done to correct the problem.
The carriage unit is in the home position with the CR locked.
Press to begin the sequence.
1. The drive of the APG Motor is transmitted to the Carriage Shaft, and Carriage Unit (Print Head) will lift
up a little.
2. The drive of the CR motor is transmitted to the Carriage Unit, and the Carriage Unit performs Head
Position detection operation in the following path.
The Carriage Unit Verifies that it's at the Home Position > It tries to move Right > then moves left
•
to confirm Carriage Unit lock position > Then moves Right to Home position.
3. The drive of the Pump Motor is transmitted to the Cap Unit, the Cap opens (lowers), and the Carriage
Lock is released.
4. After the Carriage Unit has moved leftward by the specified number of steps, the Wiper, driven by the
Pump Motor, performs the following.
• Wiper Setting > Wiper resetting.
5. The Carriage Unit returns to home position. And the APG Motor lowers the Carriage Unit to its normal
position.
6. The drive of the PF Motor is transmitted to the Media Table Drive, which then rotates for about 2
seconds (moves the Media Table about 2" at slow speed).
7. The ASF motor is rotated (this is the motor with the half moon disc on it).
8. Then the Carriage Unit moves between the left and right frames twice, the Carriage Unit moves to the
right end of the print carriage rod near the control panel. This calibrates the width sensor in the print
head.
9. The PF Motor rotates moving the media table.
Rotation for about 4 seconds (slow speed) > Rotation for about 2 seconds
•
10. The Carriage Unit returns to the home position and is secured by the CR Lock.
11. The green LED on the Green button lights solid.
