This document describes procedures to correct excess friction or obstruction in the carriage path. The most common cause of this error message is the Y-motor. Follow the steps listed below to accurately troubleshoot the issue, and replace the appropriate parts.

Parts required (part numbers are subject to change)

Part description	Model C3196A	Model C3195A
Y-Motor (Required)	C3195-60112	C3195-60112
Carriage Belt (Required)	C4706-60082	C4705-60082
Encoder Strip (Required)	C4714-60098	C4713-60098
Lubricant (Required)	6040-0854	6040-0854
Cutter Assembly (Required)	C2858-60021	C2858-60021

Troubleshooting steps

• Remove any obstructions such as jammed media from the carriage path.
• Clean and lubricate the carriage rails.
• Replace the cutter if it is bent or damaged.
• Check the main belt for fraying or other damage. Replace the belt if necessary.
• Verify the Encoder strip does not touch the carriage anywhere along the Y-axis. Replace the Encoder strip if necessary.
• Verify the rear carriage bushing is seated correctly. To reseat it, stand behind the printer, and push in on the bushing with a Flathead screwdriver until the bushing pops into place. If a pop is not heard, it is not correctly seated.
• If necessary, replace the Y-motor, the Tensioner, and the Idler Pulley.

Verify functionality

Turn the printer off, then on, and print several internal plots "E" or "D" size.
