GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR THE COPIER e-STUDIO550/650/810

The installation and service should be done by a qualified service technician.

1. Transportation/Installation

• When transporting/installing the copier, move it by the casters while lifting the stoppers.
The copier is quite heavy and weighs appro ximately 200 kg (441 lb), therefore pay full attention
when handling it.

• Be sure to use a dedicated outlet with AC 115V or 120V/20A (220V, 230V, 240V/10A) or more
for its power source.

• The copier must be grounded for safety.
Never ground it to a gas pipe or a water pipe.

• Select a suitable place for installation.
Avoid excessive heat, high humidity, dust, vibration and direct sunlight.

• Also provide proper ventilation as the copier emits a slight amount of ozone.

• To insure adequate working space for the copying operation, keep a minimum clearance of
80 cm (32”) on the left, 80 cm (32”) on the right and 10 cm (4”) in the rear.

• The socket-outlet shall be installed near the copier and shall be easily accessible.

2. Service of Machines

• Basically, be sure to tur n the main switch off and unplug the power cord during service.

• Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the
damp heater and their periphery.

• Be sure not to touch high-voltage sections such as the chargers, high-voltage transformer,
exposure lamp control inverter, inverter for the LCD bac klight and pow er supply unit. Especially,
the board of these components should not be touched since the electirc charge may remain in
the condensers, etc. on them even after the power is turned OFF.

• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, etc.

• Be careful when removing the covers since there might be the parts with very sharp edges
underneath.

• When servicing the machines with the main switch turned on, be sure not to touch live sections
and rotating/operating sections. Avoid exposure to laser radiation.

• Use suitable measuring instruments and tools.

• Avoid exposure to laser radiation during servicing.

- Avoid direct exposure to the beam.

- Do not insert tools, par ts, etc. that are reflective into the path of the laser beam.

- Remove all watches, rings, bracelets, etc. that are reflective.

3. Main Service Parts for Safety

• The breaker , door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important
for safety. Be sure to handle/install them properly. If these parts are shorted circuit and/or
made their functions out, they may burn down, for instance, and may result in fatal accidents.
Do not allow a short circuit to occur. Do not use the parts not recommended by Toshiba TEC
Corporation.

4. Cautionary Labels

• During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug
the power cord during service”, “Hot area”, “Laser warning label” etc. to see if there is any dir t
on their surface and whether they are properly stuck to the copier.

5. Disposition of Consumable Parts, Packing Materials, Used batteries and RAM-ICs

• Regarding the recovery and disposal of the copier, supplies , consumable parts, packing materials,
used batteries and RAM-ICs including litium batteries, it is recommended to follow the relevant
local regulations or rules.

6. When parts are disassembled, reassembly is basically the reverse of disassembly unless
otherwise noted in this manual or other related documents. Be careful not to reassemble
small parts such as screws, washers, pins, E-rings, star washers in the wrong places.

7. Basically, the machine should not be operated with any parts removed or disassembled.

8. Precautions Against Static Electricity

• The PC board must be stored in an anti-electrostatic bag and handled carefully using a wrist-

band, because the ICs on it may become damaged due to static electricity.

Caution: Before using the wristband, pull out the power cord plug of the copier and

make sure that there are no uninsulated charged objects in the vicinity.

Caution : Dispose of used batteries and RAM-ICs including lithium batter-

ies according to this manual.

Attention : Se débarrasser de batteries et RAM-ICs usés y compris les batteries

en lithium selon ce manuel.

Vorsicht : Entsorgung des gebrauchten Batterien und R A M -ICs (inklusive

der Lithium-Batterie) nach diesem Handbuch.

(*1) 08-449

Due to the error of an optical component such as the galvanomirror or an error caused by the passing
time of the housing, if the beam positioning adjustment is not finished correctly an temporary
countermeasure will be brought about and a mode in which printing can continue to operate be applied.
(If the H-Sync is not taken, printing is impossible)
If there is an error in the galvanomirror, then correction control is not performed and “Service Call” is
display ed so the copier stops. When image deterioration is allowab le, copier can be used without an y
judgment as to whether adjustment has been finished or not. This can contin ue untill a replacement unit
is available and service technician can use this mode for that purpose.

make sure there are no paper jams.
Increasing the aligning amount may increase

Note: When paper thinner than that specified is used, paper jams may occur frequently at the registration section.

In this case, it is advised to change (reduce) the aligning amount. Howev er , if the aligning amount is reduced
too much, this may cause the shift of the leading edge position.
Select the appropriate value when the adjustment value is changed while confirming if the leading edge is
not shifted.

* As a tentative countermeasure, the service life of the feed roller can be extended by increasing the

aligning amount.

Note for adjustment

Adjust the developer bias if fogging occurs over the entire image even though the main charger grid
voltage and toner density are appropriate. The developer bias can be adjusted at the setting mode
(08-861, 862, 863, 860, 859) (about 36V/10 steps), and the equivalent number of steps must be
adjusted for the main charger grid when adjusting the developer bias (08-865, 866, 867, 864, 871).
However, the following problems may occur if the developer bias is lowered too much:

• Image contrast becomes low.

• Image is patchy or blurred.

• The carrier in the developer material adheres to the photoconductive drum, causing scratches
around the cleaner.

3. 8. Adjustment of Developer Unit

(1) Doctor-sleeve gap
The doctor-sleev e gap is set by putting both edges
of the doctor blade against the protrusions of the
front and rear side frames and fixing the blade.
Therefore, the adjusment of the gap is not
necessary.

(2) Drum-sleeve gap
The drum-sleeve gap is set by putting the guide
rollers of the developer unit against the cleaner
unit. Therefore, the adjustment of the gap is not
necessary.

(3) Pole position of the developer sleeve
The pole positions of the developer sleeves are
set by installing the sleeve holders and pole
position fixing bushings. Theref ore, the adjustment
of the pole position is not necessary.

3. 9. Adjustment of Fuser Unit

3. 9. 1. Adjustment of fuser roller pressure

Normally, the heat roller pressure need not be adjusted. However, it must be carr ied out when wr inkles
frequently appear on copies made on plain paper.

<Procedure>
(1) Open the RADF and make a copy with A3/LD size (solid copy).
(2) Turn the power OFF after copying is finished.
(3) Open the front cover quickly, and pull out the transfer/transport unit.
(4) Insert the copy made in (1) into the fuser inlet guide with the image side facing down while turning

the jam release lever CCW until the center of the copy paper is nipped by the heat roller.

(5) Leave the copy paper for about 20 seconds, and then take it out by quickly turning the jam release

lever CCW again.

(6) Measure the width of the area nipped by the heat and pressure rollers at the front and the rear.

spring on the side with the wider nip width. One half turn corresponds to narrowing the nipped
section by about 0.5mm.

(8) If |F-R|<0.5mm, the adjustment is completed. Close the RADF and make five blank copies with A3/

LD size to clean the heat and pressure rollers.

3. 9. 2. Setting of fuser roller temperature

The fuser has been set (heat roller surface temperature: 200°C, pressurizing pressure: 100 kg)
taking the fusing performance, wrinkling, curling and toner transfer deficiency at the leading/
trailing edges of the duplex print into consideration when our company recommended paper is
used. This is to allow the characteristics of the paper to be demonstrated in a well-balanced
manner. However, various types of paper are used in the field, and factors such as the paper
thickness and smoothness greatly effect the fusing performance, in particular. If the fusing
performance deteriorates while using a specific type of paper, deal with that by changing the fuser
roller temperature at the setting mode “08”.

Change the heat roller setting temperature in the setting mode (08-410, 411, 883). The default is “8”
(200°C), and can be changed within the range “8” to “10” (200°C to 206°C). Input the same value in 80­410, 411 and 883.

Notes: 1. When a large value is set (to increase the temperature), the level of wrinkling, curling and toner

transfer deficiency at the leading/trailing edges of the duplex print tends to worsen.

2. Do not set the temperature to value larger than “12” (212°C or more). The fuser thermostat
actuates to turn the power OFF, and the thermostat must be replaced.

3. 9. 3. Adjustment of fuser inlet guide

Check the gap between the fuser inlet guide and the press roller when the following troubles
occur:

• Stain on the paper back side

• Jam at the fuser entrance

• Paper wrinkling

(1) Move the screw fastening position of the inlet

guide towards the oblong hole, and adjust with

reference to the scale.

(2) Adjust the gap between the fuse inlet guide

and the pressure roller. (0.4

3. 9. 4. High-fusing mode

When the fusing level needs to be raised, it can be set at the setting mode “08”.

(1) Level up at 1st printing
The level for the 1st printing is set at the “high-fusing mode 1 (08-434)”. The level is raised by delaying
the time for the 1st printing and extending the time to warm the fuser roller. At this code, the time to
delay is set.

(2) Level up at continuous printing
The level for the continuous printing is set at the “high-fusing mode 2 (08-433)”. The level is raised by
delaying the printing cycle and controlling not to lower the fuser roller temperature.

Note: (1) and (2) can be combined.

The above settings are reflected when the “Thick paper 2” is selected.

3. 10. Adjustment of Exit/Reversal Unit

3. 10. 1. Adjustment of sideways deviation at reverse discharging

When a paper sideways deviation occurs at
reverse discharging, the transport guide position
is adjusted through the following procedure.
(1) Open the exit side door.
(2) Loosen 6 screws fixing the transport guide.
(3) Remove 2 screws, and take off the plate.
(4) Set the plate lengthwise, and fix it again with

2 screws after adjusting the plate installing
position depending on the paper deviation
amount.

(5) Remove 2 screws, and take off the plate with the latch holder.
(6) Turn the latch holder to the opposite direction, and install it to the plate.
(7) Turn the plate upside down (with the long hole upside), and install it again with 2 screws after

adjusting the same amount as did in the above (4).
