Canon E202 — Scanner home position error

What this error means

The scanner carriage could not find its home position — the optical unit is stuck, the position sensor failed, or the drive belt slipped.

Symptoms

• Copying/scanning fails but printing from a computer may still work
• Grinding from under the platen glass
• Carriage visibly stuck mid-track

Try this first (safe DIY steps)

1. Power off, check for shipping lock (a slider under or beside the platen glass on many models) and set it to unlocked
2. Look under the glass for obstructions (paper clips, staples)
3. Power cycle

Safety: power off before any physical intervention. Never bypass covers or interlocks — fuser areas run hot enough to burn.

When to call a technician

If the carriage still won't home — belt or sensor replacement.
