TOSHIBA THE 60TH SERIES ANALOG COPIERS – DETACHABLE
OPTIONS FOR 1550 2060 3560 AND 4560 MODELS
OVERVIEW
Following the technical review of all analog copiers from Toshiba 60th series, comes the
present article about the extensive list of detachable option modules. The available options are
RADF – reversing automatic document feeder (ADF – automatic document feeder); LCF –large
capacity feeder; Sorters with or without stapler; ADU – automatic duplexing unit and Pedestal.
The copiers from the 60th series are quite capable of doing most of the daily copying needs
of the users, but however nothing is perfect. So there comes the options list.
- The RADF module enables users to copy up to 50 originals at a time automatically both one and
two sided.
- The LCF is a useful option for users that demand a steady continuous supply of copy paper. The
module has a capacity of 1500 sheets.
- The sorter is a valuable option module for copy shops and busy offices, which operate with great
number of multiple pages documents that need to be copied, sorted and stapled in up to 20 sets at a
time. The sorters available are either of 10 or 20 bin types. The fist is a hanging type and the second
is a stand-alone type. The stand alone type demands the original stand desk of the machine to be
used or the optional pedestal module, for correct alignment of the sorter with the copier.
- The ADU module is also preferable for busy offices. There is no need to explain the advantages of
automatic double-sided copying.
- The pedestal is yet another option for even greater volume of copy paper supply. It consists of
either 3 of 2 auxiliary paper trays with variable paper formats.

PERIODICAL MAINTENANCE – USEFUL PRACTICES
In general, the option modules are very reliable and rarely need special attention, apart from
the regular maintenance and replacement of worn parts (mostly rubber parts). However the goal of
this article is, as usual, to give you guidelines to proper maintenance.
1. REVERSING AUTOMATIC DOCUMENT FEEDER (RADF) MR-3006/2008
The main difference between the two models is that the second can handle only one sided
originals. This is preferred for machines that have no duplexing module for 2 sided copies.

In order to better troubleshoot and repair malfunctions in this unit it is useful to understand
how it works. The construction of the module is shown on figure 3:

Disassembly and adjustments:
1. Slide the originals guides towards each other.
2. Remove screws A. See figure 4:

A
3. Lift the RADF. Remove screws A and B. Note the relative position of the smaller hinge to screw
B. This is an important reference used for correcting image skew. Unplug the module’s
connector to the copier (located at the back of the machine). Remove the module in direction C.
See figure 5:

4. Remove the cover A by unscrewing three screws. Remove the four plastic clips B that hold the
ADF’s transport belt assembly C and remove it. See figure 6:

5. To remove the exit/reversing assembly remove screws A. Open the cover B and remove the
entire assembly. Be careful with the wire connectors. You should remove the assembly only if
you plan to make repairs on it. Otherwise open the cover B and clean the three transport tires C
with rubber restoring fluid. Clean with vacuum cleaner the transport belt cleaning brush D. See
figure 7:

C B

6. If you received a service call related with RADF/ADF original exit problems, you should remove
the exit assembly. Follow the instructions in stage 5. If cleaning the exit rubber rollers doesn’t
solve the problem, look at the spring clutches A. They are responsible for the transport of the
original in the exit direction and in the reverse direction when making double-sided copies. Often
after a significant number of originals fed through the module, these spring clutches break. See
figure 8:

7. If your clients complain that the ADF module doesn’t stand in the open position and the copies
are skewed and some times the originals even don’t exit, causing paper jams, you should look at the
main hinge of the module. It is made of a spring and a shock absorber inside. If the module doesn’t
stand open it indicates the absorber is worn. This causes the module not to close entirely on the
original glass. The originals are not correctly transported onto the glass and thus the copy is skewed.
The solution is to replace the entire hinge assembly. See figure 10.
8. If you want to replace the pick-up, feed of separation tires in the ADF module, you should
remove the entire feed assembly; otherwise only clean the feed rubber parts with rubber cleaning
fluid. To remove the feed assembly remove screws A and B. Unplug the connectors C from the
main board. See figure 9:

9. Open the left ADF cover and loosen the screw A. Figure 10.

10. Remove the feed assembly. If you are not sure how to disassemble it, consult the service manual,
because it has a rather complicated mechanics. See figure 11:

Adjustments:
1. Adjustment of skew (image inclination):
(1) Please confirm the installation as shown (RIGHT HINGE).
Note: Install the screw on the center of scale.
(2) Place the test original face up in the tray, press PRINT to make a copy.
Check that the copy isn’t skew.
(3) If not, loosen the two screws on hinges and adjust the position of RIGHT HINGE. Repeat the
procedure until the copy isn’t skew.
Note: After the adjustment, tighten the two screws of LEFT and RIGHT HINGE without fail.
2. LARGE CAPACITY FEEDER (LCF) MP-1501
As far as my experience goes – this is a very reliable module. I’ve hardly ever made repairs
on it, apart from the regular cleaning and repair of the pick up, feed and separation rollers.

Periodical maintenance and replaceable parts:

Disassembly and adjustments:
If you plan only to perform a periodical maintenance of the module, you should open the
LCF’s door while the tray is in the upper position and clean the bottom of the module with vacuum
cleaner. Then close the door and press the tray-down button. When the tray is down open the front
door and clean with rubber restoring fluid the pick-up, feed and separation rollers. Note: some times
operators complain about frequent paper jams in the module, but the pick up and separation rollers
are ok. You should look at the separation roller – often it wears unevenly. If the roller has a worn
strip along its length, you should replace it. To replace the three feed rollers follow the instructions
bellow.

1. Press the tray-down button. Wait until the tray is in the lowest position. Lift the handle A and
open the LCF. Open the front door too. Loosen screws B. Remove screws C. Remove the upper
cover. See figure 12:

2. Remove screws A. Remove the separation roller plate in direction B. See figure 13.

3. To remove the separation roller push the assembly tabs A. See figure 14.

4. To remove the pick up and feed tires, remove one screw A, a plastic clip B, the bronze bushing
C and the support plate D. Remove the cylindrical weight E from the pick up roller and pop out
the shaft from the white lever F. You should be able now to pull out the pick up roller. Remove
the white lever from the feed roller shaft. Pull out the feed roller. Note: pay attention to the
orientation of the rollers. They have built in one-way clutches and if you change their
orientation during assembly the feed mechanism won’t operate at all. See figure 15.
