Canon Pixma G3110 Error 5100 | Carriage Path Blocked
Error code 5100 on the Canon Pixma G3110 signals a carriage translation error. It occurs when the printhead cradle encounters physical drag along the slide rail or when the optical sensor fails to read the transparent encoder strip.

Common causes
- 1Torn paper scraps or foreign bodies blocking the carriage slide path.
- 2Ink tube delivery harness dragging against the carriage body.
- 3Toner dust, ink splatter, or grease smudges on the translucent encoder ribbon.
Solutions
Troubleshooting Carriage Error 5100
This fault is generally related to dirt on the tracking strip or loose objects inside the print cradle's path.
Solution 1: Check Carriage Path for Objects
- Turn off the printer and disconnect the power cord.
- Open the main scanner compartment.
- Manually slide the printhead carriage gently from side to side.
- Check for objects: torn paper shreds, foreign objects like paperclips, thick grease buildup, or ink tubes that have popped out of their harness loops.
Solution 2: Clean the Thin Encoder Strip
The encoder strip is the narrow, semi-transparent plastic band running horizontally behind the carriage track.- Locate the clear plastic strip inside the printer.
- Moisten a lint-free cotton swab with isopropyl alcohol.
- Wipe down the strip very gently. Do not apply heavy pressure or yank on the strip, as stretching or unhooking its spring tensioner will corrupt printhead coordinates permanently.
Steps to follow
- 1
Unplug the G3110 printer
Disconnect the AC plug to safely manipulate the printhead carrier by hand.
- 2
Clean the encoder ribbon
Gently clean ink smudges off the clear plastic tracking strip running behind the carriage rail.
- 3
Verify tubing routing
Ensure the continuous ink hoses do not catch or kink during carriage sliding tests.
Frequently asked questions
This indicates a dirty encoder strip. Since the optical sensor cannot locate its boundaries, the motor slams the carriage against the side walls.
