MAINTENANCE/HOW TO STORE
Carry out the following maintenance procedures periodically to ensure high quality copying performance at all times.
(1) Cleaning of the surface ....... (BF-030S/W only)
When the surface gets stained, wipe it off with a slightly damp cloth. Also, if the stain is particularly stubborn, use
a solution of water-thinned neutral detergent to wipe it off. Do not start using the machine until the sheet has
completely dried.
(2) Cleaning of pages 1-4 ......... (BF-035 only)
When the surface gets stained, wipe it off with a slightly damp cloth. Also, if the stain is particularly stubborn, use
a solution of water-thinned neutral detergent to clean. Do not start using the machine until the panel has completely
dried.
(3) Cleaning of projection screen (page 5) .......... (BF-035 only)
Wipe ordinary stains in the same manner as shown in (1).
If something is written on this screen by accident, wipe it off with a cloth dampened with a neutral detergent.
(4) Cleaning of tray and decorative frame
Wipe away any dirt or residue left by the markers in the tray and the decorative frame with a slightly damp cloth.

HANDLING PRECAUTIONS
<FOR SAFE USE>
1. Avoid placing the machine in hot spots where it is exposed to direct sunlight or where an air conditioning duct.
2. When using sticky tape on the surface of the board screen, do not leave it on for a long time. Moreover, after
removing it, wipe the screen clean. Do not hit or pierce the board screen with any hard or sharp objects.
3. Do not leave writing or marks on the board screen for a long time since it sometimes become difficult to erase
(BF-030S/W only).
4. Be careful not to stain the joints of the board screen as there have been very rare cases where such stains have
been copied. ...... (BF-030S/W only)
5. Do not leave writing or marks on pages 1-4 for a long time since it may become difficult to erase. ..... (BF-035 only)
6. As thinner, benzine, alcohol, etc., may discolor or mark the main unit and the board screen, never use such
chemicals when cleaning. (BF-030S/W only)
7. As thinner, benzine, alcohol, etc., may discolor or mark the main unit and the panels, (1-4 page) never use such
chemicals when cleaning. ........ (BF-035 only)
8. Use only the correct type of thermal paper.
9. When replacing recording paper, do not place any objects on the open printer cover or do not put your elbows on it.
10. After use, make sure to turn OFF the power switch. In addition, when it is not to be used for a long time, make
certain that the plug of the power cord is pulled out form the outlet.
11. Always use the correct type of marker. Be careful not to use other markers as the sheet may be damaged or, in
some cases, the ink may be difficult to remove.
12. Write within an area of a size that can be easily read.
When storing thermal recording paper, avoid the following places. This is important because storage in such
places may cause color development or discoloration.
(1) Places where the paper is exposed to direct sunlight.
(2) Places where the paper is exposed to temperatures of more than 35˚C (95˚F) and humidity of 85% or over.
(3) Places adjacent to alcohol, thinner, benzine, ammonia, etc.

ADJUSTMENT MODES
There are the following methods for entering each mode.
(1) Adjustment 1: Switch on the power while holding down SW5.
(2) Adjustment 2: Switch on the power while holding down SW1 and SW4.
To end an adjustment mode, switch off the power and switch it back on without holding down any of the keys. (Test
mode continues until the power is switched off.)
Adjustment mode specifications
No. Function summary Operation method Adjustment 1/2/3 Remarks
1 Test pattern printing Press SW3. 1 Both 2-surface/5-surface
2 Arbitrary sheet feed Press SW1/SWS5. 1 5-surface only
3 Continuous sheet feed (1 surface ↔5 surface) Press SW1. 2 Both 2-surface/5-surface

5 20% continuous printing Press SW3. 2 Both 2-surface/5-surface
6 Test pattern printing Press SW4. 2 Both 2-surface/5-surface
7 Continuous copying Press SW5. 2 Both 2-surface/5-surface
✽From the left side of the operation panel, the switches are SW1 - SW6.
✽For the 5-surface model, in Adjustment 1 mode, the COPY/STOP key is for normal copy/copy stop processing, but
sheet stretching/rewinding is not carried out.
1. Test pattern printing
Pressing SW3 prints the test pattern shown in the print
sample (same as for BF-030).
Each time SW3 is pressed, the printing is repeated.
The STOP key is enabled.
2. Arbitrary sheet feed (5-surface only)
(1)Pressing the L-FEED/R-FEED key alone feeds the
sheet about 1 cm left/right (with the motor driven at
low speed).
If you hold the key down for longer than 0.5 second,
the sheet is fed continuously left/right until you release
the key.
(2)If you press the R-FEED key while holding down the
STOP key the sheet latch is released/set. When the
sheet latch is set, all the LEDs except the paper end
LED lights up (to show that the paper tube can be turned
manually).
<Notes>
. These modes do not manage the pages with the CPU,
so be careful when working near the edge of the sheet.
. The sheet is not stretched after the sheet feed
operations.
. When the sheet latch is set, the sheet is not fed other
than for 1-cm feeds (Item 1).
. When the sheet is fed at positions where the paper
tube is thick, the movement distance decreases due
to insufficient torque.
. The fluorescent lamp is always lit. (It is not
extinguished even if the gain check result is NG.)
3. Continuous sheet feed
After a power-on reset, pressing SW1 feeds the sheet
continuously.
The interval between surfaces is about 2 seconds. For
the 5-surface model, the sheet is stretched each time
a surface is fed.
Continuous feed is an unending loop that continues
until the power is switched off. (The STOP key is
disabled.)
4. 12.5% continuous printing
Pressing SW2 continuously prints a black belt (about
10 mm) diagonal line at intervals about 12.5% of the
paper width.
The interval for each sheet is about 2 seconds.
5. Pressing SW2 continuously prints the same
as for Item 4, but with intervals of 20%.
6. Test pattern printing
Pressing SW4 prints the test pattern. The STOP key
is disabled.
7. Continuous copying
Switching on the power in Adjustment Mode 2 and
pressing SW5 automatically starts continuous copying
operations.
The interval between surfaces is 3 seconds.
For a 5-surface model, from Surface 1 to Surface 4 is
copied and after these four surfaces have been copied,
the sheet is returned non-stop to Surface 1 and
consecutive copying resumes.
Continuous feed is an unending loop that continues
until the power is switched off. (The STOP key is
disabled.)
Hidden mode
For a 5-surface model, if the power is switched on with
SW5 and SW6 held down, the sheet latch is released.

CCD BOARD ADJUSTMENT
1. Initialization
1) Range setting of oscilloscope
CH1 100 mV/div. (for 10:1 probe)
CH2 20 mV/div. (for 10:1 probe)
Time base 0.5 ms
Coupling DC
2) Connect the probe to the test pin on the main board.
CH1 J9
CH2 J1
CH3 J10
GND J2
The trigger source for Channel 3 coupling is AC.
3) GND position adjustment (See the figure on the right.)
Immediately after the oscilloscope power is switched
on, the ground position fluctuates easily, so
occasionally check that the Channel 1 coupling is
aligned to ground.
2. Temporarily Fixing of Lens Unit
•Fix SC(1) temporarily by the adjustment of the back
plate and end face.
•Fix SC(2) temporarily in the horizontal state.
•Fix SC(3) temporarily in the center position.
•Fix SC(4) temporarily with the CCD board put in the
vertical state.
•Fix SC(5) (square screw) temporarily in the position
where the lens barrel is 2 mm forward from the holder.
•Fix the shade temporarily in the position where it was
brought near the sheet.
✽Adjustment mode
Switch on the power while holding down the STOP key
(BF030S/W) or the PAGE-R key (BF-035).
3. Optical Axis Alignment
1) Loosen SC(2) and shake the board forward and
backward until the waveform on the oscilloscope is
as shown in the figure. (Saturation)
3.8 V or more
3 ms or more (6 divisions)

2) Slide the lens shade to adjust the amount of light so
that the aperture peak waveform is flat, then secure
the lens shade in place. (See the figure on the right.)
Adjustment range (limit values) 2.6-3.4 V
Adjustment standard 3.3 V
Be careful not to exceed the top limit of 3.8 V.
4. Focus Adjustment
1) As shown in the figure, enter a pattern, obtained when
50 mm square was divided into 36 equal parts, in the
red vertical line and the upper and lower ruled lines
of two lines of 3 mm in width.
2) Confirm that the CCD waveform is 2.6 V or more.
•Search the lowest falling position of the waveform
while moving the lens barrel from the fluorescent
lamp to the CCD board and fix the lens barrel in the
corresponding position.
•The falling value of the black level should be less
than 2.3 V from the GND level as the reference
value.
5. Reading Width Adjustment
1) Adjustment reference value: 890 to 910 mm
2) Reading width adjustment
•Loosen SC(3) and adjust so that the reference line in the
figure is uniformly copied in the vertical direction while
shaking the lens unit upward and downward. After that,
fix SC(3).
•If the reading value is higher than the reference value,
loosen SC(1) and move the whole lens unit to the right. If
it is lower than the reference value, mode the whole lens
unit to the left.

6. Optical axis alignment
•As shown in the figure, enter a mark on the block
vertical line and at a point 71 mm away from the black
line.
•Move the sheet until the mark moves to the left edge.
(The vertical line is reflected in the center of the mirror.)
•Move SCs 2 and 4 to make the waveform shown in
the figure.
7. Shade adjustment
•Switch the power off, then switch it back on in normal
mode.
•Make two waveforms appear on the oscilloscope.
•Set the oscilloscope mode to Chop.
●Channel 1 The gain is automatically adjusted and
the waveform amplitude becomes
larger.
●Channel 2 The actual waveform (The waveform
in the figure has a different ground level
from Channel 1.)
8. Print check
•If the waveform is tilted, flatten it with the shade. (Align
to 3.0-3.5 V.)
•Tighten the SCs.
•Check that the print patterns are copied within the
standards.
Reading width: 890-910 mm
Focus: 2 lines with widths of 3 mm must be
printed.
Also, the measurement grid must not
be broken.
Others: After copying one surface, check that
there are no dark lines on the copy.

Cautions for Maintenance
•In principle, when lens units and CCD boards are
replaced in the field, use a factory-adjusted unit (lens
unit + CCD board).
•Procedure for adjustment after replacement
(1) Temporarily secure the adjusted unit with SC1.
(2) Check the light shaft alignment.
(3) After adjusting the reading width, secure the unit
with SC1.
(4) Check printing.
