- Remove the original tray. (Original Tray)
- Remove the original feed unit. (Original Feed Unit)
- Remove the DF inner cover [A].
The bracket cannot be removed from the DF unit, because doing so interferes with the paper transfer roller. However, remove the screws to make space for removing the registration sensor.
- Attach the connector to the registration sensor before attaching the registration sensor to the bracket.
Be careful not to tighten the screws too much. Doing so may deform the bracket.
- Check the degree of protrusion of the registration sensor (the position of its tip) with a ruler. If it is within 4 to 5 mm, the sensor is correctly attached. If not, the registration sensor bracket may be attached (screwed on) incorrectly, so reattach the bracket.
- Check the movement of the registration sensor’s actuator. Rotate it in the direction of the arrow. If it moves without getting snagged, it is attached correctly. If it gets snagged or does not move, the registration sensor bracket may be attached (screwed on) incorrectly, so reattach the bracket.
- Scan a document to check for vertical registration errors. If there is a registration error, adjust using the following SPs.
