Abstract

A mechanism automatically connects the communication cable between a docked finisher and a printer. The proposed invention uses a solenoid to connect the terminals between the devices when the machine is powered on. A sensor will detect when the finisher is being undocked with the power on and signal the solenoid to disconnect the cable. When there is no power to the printer the solenoid will de-energize and open the connection. Benefits include no need for an external communication cable and reduced communication faults due to improper manual connection.

Auto Connector for Printer-Finisher Communication

Introduction

There are usually two cables between the multifunction printer and a finisher – a power cable and a communication cable. These cables are external and connected manually. The power cable is connected directly with a 3-pin connector.

The communication cable is connected using a 15-pin connector with screws. We propose to eliminate the process of manually connecting the external communication cable and incorporate a mechanism to connect the communication cable automatically. No external visibility of the cable.

Current Design:

Finisher-printer communication in the current design is through a conventional external wire connected manually.

Fig.1 Current design

Currently, the finisher is docked and latched with the printer and finisher communication cable is manually connected and screwed. This invention aims to eliminate the visibility of this communication cable outside the machine and automate the process of connecting the cable, thereby reducing the time and effort of fixing the cable manually.

This would also eliminate frequent ‘Finisher Communication Error’ fault codes that occur due to improper fixing of the connector.

Proposed Concept:

An auto-connector mechanism makes use of a solenoid and a sensor to connect the finisher communication cable to the printer. The solenoid actuates pivoted and slotted links that move the male connector along a guide (as shown in Fig.2)
