Canon PIXMA Pro-10 error 5203: Sensor Solution

Canon PIXMA Pro-10 error 5203 is a code triggered when the carriage movement sensor cannot correctly read the encoder strip, responsible for coordinating the print head position. When the printer loses reference of the head's location, it stops to avoid accidents. If you are asking why my Canon PIXMA Pro-10 shows error 5203, it is likely the strip has grease or dust stains.

Common causes

  • 1Opaque strip: Grease or dust block sensor reading.
  • 2Damaged sensor: The carriage optical reader is not working.
  • 3Damaged strip: The strip has physical marks or cuts.
  • 4Light interference: External light affecting the optical sensor.

Solutions

Quick Diagnosis

The error usually appears before the printer starts printing. If the transparent strip is visibly opaque, that is the cause of error 5203.

Step-by-step Solution

  1. Disconnect the printer completely.
  2. Locate the transparent strip behind the carriage bar.
  3. Wipe it with a soft cloth (lint-free) slightly dampened with distilled water.
  4. Let it dry before attempting a new start.

Prevention and Maintenance

Never use harsh chemical solvents on the strip; they can erase the encoder marks. Always use a clean environment for the printer.

When to Call a Technician

If the strip is scratched or cut, cleaning will not work. In that case, a technician must replace the encoder strip.
