Toner interface installation processFor : Spirio 4220/4240 and ST 4520/4540/4550

I- Purpose- When you install Interface for those models of Sindo Ricoh machines,

they will use TNT 4200 toner (instead of using their own toner)- When you use toner TNT 4200, the copies quantity will be increase

and it’s price is cheaper.- In short: After installation interface on machines, they will supply

toner and detect Add toner condition same Phoenix Series of Ricoh

II- Installation

A/ With SP 4220/4240 machines:1/ Open Front cover, remove Toner supply unit and disconnect 2 Connectors. In the Toner supply unit has toner sensor cable, please remove it.

1

2/ Open Bypass Tray and remove the metal cover (2 Screws)

3/ Remove Front right cover and Rear right cover (2 Screws). Remove Rear cover(4 Screws).4/ Now, you can see the bunch of wires on the right of machine.

2

5/ Remove development unit(1 Knob Screw and 1 Connector). To see on the right side of machine, you can see the place of toner sensor cable connecter. Remove it out of the machine.

3

The toner sensor connector is five pins bridge. When remove it, the connector was connected it to be disconnect and passed through follow the bunch of wires on the right of machine.

6. The five pins bridge is cut some part follow under figure

Original Modify

* If you don’t want to cut some parts in the five pins bridge, you can change position of wires in the toner sensor cable. Following under figure:

Toner sensor cable Toner sensor cable

The order of wires position you can change as follows:- Blue wire(1) changes place to green wire(5) and vice versa.- Black wire(2) changes place to yelow wire(4) and vice versa.- Red wire(3) stays at its position.

7. To connect right part of five pins bridge to connector which was passed through follow the bunch of wires on the right of machine (Step 6). Left part of five pins bridge is connected to toner sensor cable which is removed in step 1Note: When toner sensor cable is connected contrary to five pins bridge. Some part of five pins bridge was cut or to change wires position of toner sensor cable in step 6 will help this contrary connecting.(See under figure)

If changing position of wires in the toner sensor cable, connect bunches of wire to five pins bridge, you don’t need to connect contrary

After connecting, please roll around five pins bridge by adhesive tape, to avoid electric shock.8. In the bottom of main board, there is a metal piece with 2 holes in it. This is the place to install toner interface. Insert 2 plastic pins in 2 holes and install toner interface in 2 plastic pins. A head of the toner sensor cable is connected to Toner interface. (See under figure)

9. Reinstall every part which were removed in upper steps. Plug power and turn on main switch. Wait to ready and make some copy. The machine operate normally to be meet or fufill the demands.If there is any error occur, check connectors again.

B/ With ST4520/4540/4550 machines1. To do step 1 and step 8 in process for SP4220/4240. The fundamental

difference is toner cable connecting (The toner cable was removed in step 1)

2. A head of toner cable is connected to toner interface, the other is connected to CN150(W) on the main board.The connector was connected to CN150(W) before to be disconnected and leave unfinished

C/ Footnotes:- Every bunch of wires are keft well in the wire holders, to avoid they

are broken by michanism and gears when operating. .- The connectors are reliable and contrated, to avoid they are removed

when operating.

Toner Interface Installation ProcessFor NT 2070/2090

With Toner Interface, We can use TNT toner for NT2070/2090 that no sensor in it. When we install Toner interface, The machine doesn’t display U8 error and it will operate the same as FT 4422 of Ricoh.

This is Toner Interface Installation process for NT2070/2090:Before Install Toner Interface, Ensure that the machine operate

normally with its original toner.1. Turn off main switch and unplug power cable.2. Remove Front cover, Development unit. Then, remove Inside

front cover.3. You can see the toner sensor cable under control panel.

Disconnect and remove it.(See figure 1)

4. Remove rear cover and remove a scew on the left bottom of main board.

5. Install Toner Interface on the left bottom of main board with a screw which is removed in step 4. (Carefully when Install Toner Interface. Ensure that Toner Interface circuit doesn’t contact with Main board circuit , cause electric shock).(See figure 2)

7

6. Disconnect the CN 106 on the main board.7. Connect a head of Toner sensor cable in CN106 on the main

board, and another head is connected in the Toner Interface (See figure 3)

8

8. Reinstall Front cover, Development unit and Inside front cover. Plug power and turn on main switch.

9. To copy some page. If there is any error occur, please check connectors on main board and Toner Interface.

10. If you want to insert TNT toner cartridge in the hopper, you must remove one pin on rear of hopper (See figure 4) .
