Canon imageFORMULA DR-C230 error E004: Cover Open Fix

The Canon imageFORMULA DR-C230 error E004 is an alert triggered by the scanner's safety cover interlock. When the scanner cannot confirm the top unit is firmly closed, it blocks operation to prevent injury or damage. This is usually caused by simple debris blocking the lock mechanism or a loose closure. Resolution is quick and involves checking the physical seating of the cover.
