Solutions

Quick Diagnosis

The E-200 appears immediately upon startup or when printing. If you open the front cover and notice cartridges are not seated in their guides, the presence sensor won't activate.

Step-by-step Solution

  1. Remove cartridges: Open the front cover and extract each toner cartridge gently.
  2. Clean contacts: Wipe contact chips with a dry cloth to remove any dust or toner soot.
  3. Reinstall: Place each cartridge back, pressing until you hear a 'click' locking it in place.

Prevention and Maintenance

Avoid unnecessary shaking of cartridges, as it can loosen toner onto contact chips. Keep the printer in a dry place free of dust to prolong electronics life.

When to Call a Technician

If the code persists after reinstalling all cartridges, the internal sensor on the mainboard might be defective and require replacement.
