TOSHIBA THE 60TH SERIES ANALOG COPIERS – THE MIDDLE CLASS:
2060 3560 AND 4560 MODELS
OVERVIEW
As a logical progression to our series of articles, about Toshiba analog copiers, comes the
current and last addition. By “last” I mean that there is not particular interest in discussing the high
end copiers over 50 copies per minute, because they are relatively rare and not many technicians get
a chance to work on them. The next addition to the series of articles will cover the most common
and distinct defects, found in the previously discussed models, but not before we familiarize
ourselves with the middle class analog copiers of the 60th series. See figure 1.
These machines are namely 2060/2860 3560 and 4560 (the 2860 model has and automatic
duplexing unit as standard, opposed to 2060, where it is an option). There is a variety of ad-on
options the user can choose to attach such as: 10 and 20 bin sorters with staplers, large capacity
feeders LCF, automatic and reversing document feeders ADF and RADF and automatic duplexing
unit ADU. The maintenance and troubleshooting of these options will be discussed in a separate
article to come. In the current article the 2060 model is used as a basis, because the other models
have generally the same structure apart from subtle differences in mechanical design, related to the
higher copying speeds and the resulting higher durability demands.
These machines are the backbone of the copying industry in many countries in Eastern
Europe. Found in many offices and copy centers, they are tough, reliable and easy to maintain. It is
now uncommon to maintain copiers which made 2, even 3 million copies. This fact speaks of the
reliability of the design of these copiers. Even more – most of the parts and systems are designed as
a module, which makes it very easy for a service technician to remove, replace and service them. Of
course there are underwater stones. Some of the modules require special attention after a certain
period of useful service. From my experience, the first 400 000 to 600 000 copies period passes
almost routinely. During this period the only necessary work to do is to make periodic maintenance,
cleaning and a scheduled replacement of the parts from the periodic replacement checklist shown

bellow. How ever there are some tricks, which can prolong the life of some parts, such as: the
silicone felt cleaning roller, the aligning roller, the paper pick up and feed rollers. For example:
given the machine is maintained properly the OPC drum can easily make twice the normal copies
recommended by the manufacturer. After the 400 000 to 600 000 period it is possible to encounter a
variety of defects in certain modules such as the fuser, developer, feeding and drive system modules.
How ever there is nothing to worry – there will be a special article dedicated only to defects not
mentioned in the service manual.
As I always mention: most of the defects in copiers that are still under 400 000 copies are
due to poor maintenance and cleaning.
1. PERIODICAL MAINTENANCE – USEFUL PRACTICES (TOSHIBA 2060/2860)
Inspection every 80,000 Copies
(1) Preparation
1 Ask the key operator about the present machine conditions and note them down.
2 Before starting the maintenance work, make and retain a few sample copies for later comparison.
3 Turn off the power switch and disconnect the power cord plug.
(2) The periodic inspection should be conducted in accordance with the Periodic Inspection Check
List shown below. Perform the inspection by referring to the figures, as well as to the explanations
in the Service Manual when necessary.
(3) After the inspection has been completed, plug in the machine and turn the power switch on, and
confirm the general operation of the machine by making a few copies and comparing them to those
made previously.
Inspection and Overhaul every 240,000 Copies
(1) Replace all the consumables.
(2) Check to see if there is any damage to the parts of driving section (gear, pulley, timing belt, etc.).
Replace parts on principle if damaged.
(3) Check to see if there is any damage or peeling of adhered parts (tape, Mylar sheet, etc.). Replace
any affected parts.
(4) Check to see if all the switches and sensors operate properly. Replace them if they are not
operating properly.
(5) Clean the inside of the machine thoroughly.
Periodic Inspection Check List
On figure 2 and 3 you can see the actual position of item numbers in the list bellow:

Symbols used in the Periodic Inspection Check List:

Figure 3 – Positions of item numbers in rear side view
Explanation of items in the “REMARKS” column of the Periodic Inspection Check List:
*1 Main blade
Clean the main blade with a cloth which should be soaked in water and then squeezed tightly. If
poor cleaning occurs due to the adhesion of paper dust, etc., the edge of the blade has been damaged.
Replace the blade regardless of the number of copies made so far.
*2 Recovery blade
If the edge of the blade is damaged, replace the blade regardless of the number of copies made so
far.
*3 Separation claw
If the tip of the separation claw has been damaged, replace the claw regardless of the number of
copies made so far. Clean the tip of the claw by lightly wiping with a dry cloth. After cleaning,

make sure to remove bits of lint from the claw. In addition, be sure to apply patting powder
(lubricant) to the separation claw after cleaning the claw and when replacing the claw or drum.
*4 Drum
Refer to section “3.2 Inspection and Cleaning OPC Drum” in the service handbook
*5 Air filter
If the air filter is dirty, replace it.
*6 Charger wire and case
Clean the inner surface of the charger case and the charger wire with a cloth which should be
soaked in water and then squeezed tightly.
*7 Grid
Remove the grid from the main charger. Clean the grid with a pad (service part) moistened with
water.
*8 Developer material
After replacing the developer material, be sure to adjust the corresponding auto-toner sensor – look
in the service handbook.
*9 Front shield
Clean it with a cloth which should be soaked in water and then squeezed tightly.
*10 Heat roller - Refer to section “3.5 Checking and Cleaning Upper and Lower Heater roller of the
service handbook.
*11 Pressure roller - Refer to section “3.5 Checking and Cleaning Upper and Lower Heater roller of the
service handbook.
*12 Cleaning felt roller - Refer to section “3.4 Checking and Replacing Cleaning Felt Roller” of
Service Handbook.
*13 Scraper
If the tip of any of the scraper claws is chipped, replace it regardless of the number of copies made
so far. If toner adhering to the scraper claw is forcibly scraped off, it may be damaged. Therefore, if
the tip of the claw is heavily coated with toner, replace the claw.
*14 Heat roller cleaning blade
Refer to section “3.6 Checking and Cleaning Heat Roller Cleaning Blade” of this Service Handbook.
*16 Apply white grease to the main motor drive unit gears (shown arrow). See figure 4.

Figure 4
Bellow is the oiling cycle table given by the manufacturer. I advise to stick to it if you want
to have less problems with the machine after the “trouble less” period of 400 000 to 600 000 copies
period.

2. REPLACEMENT SCHEDULE OF DISPOSABLE PARTS AND SUPPLIES
Bellow are shown the replacement schedules for the models 2060/2860, 3560 and 4560.
This is the only difference in the three models are the intervals between the cleaning, oiling and
replacement of parts. In that way the only thing you have to do in order to determine the proper
maintenance for a 3560 or 4560 model is to replace the corresponding interval in the tables above.
For Toshiba 3560 this interval is 120 000 copies ad for 4560 – 160 000 copies.
