1.6 SAFETY NOTICES – LAMINATING AND PRESSURE ROLLER ZONE
The operating laminating roller temperature, depending on the type of laminating film, is 210 to 300 °F
(100 to 150 °C). In order to maintain the machine function, it is not possible to cover all the zones near
the laminating and pressure rollers. This is very hazardous due to the high temperature and crush
hazard. Therefore the following precautions have to be followed strictly.
WARNING
Obey the following precautions. Failure to do so can result in severe personal injury or damage the
machine.
• Never touch the hot laminating roller.
• Keep your hands and body away from the contact surface between the laminating roller and
pressure roller where there is a crush hazard.
• When loading the first sheet of paper with film through the nip, keep your hands and fingers at
least 8 in. (200 mm) behind the nip point of the laminating and pressure rollers. Failure to do so
can cause severe injury.
• Use the "SLOW FWD" or "SLOW REV" buttons for cleaning. Never clean the surface of the
rollers while the machine is in operation.
• Wear tight fitting clothing while working near the laminating and pressure rollers. Loose clothing
can get caught in the moving rollers.
• Do not use any objects for cleaning the rollers or removing the film residue while the machine is
in operation.
• The Plexiglas cover above the laminating roller must be closed while the machine is in

laminating roll and pressure roll.
Note: Refer to the illustration on the next page for the remaining steps, which follow the illustration.
3. Check for the film adhesive side "Poly - out" or "Poly – in."
One side of the film is coated with an adhesive. It can be checked:
• Visually - the side coated with adhesive is not as glossy as the other side.
• By placing the film on the edge of the laminating roll - the adhesive side of the film will stick.
• According to the color stripe on a new film (red or blue).
Depending on the coated side of the film, the roll of film is put on the unwind shaft.
4. Positioning the roll of film on the unwinding shaft.
a. Adjust the thread bushing by turning the regulating nut so that the white stripe on the holder
runs along the edge of the sliding nut –See Section 5.2
b. Tighten the reel with the conical holders so that the film centered with the paper sheet in the
feeder. This distance should be measured from the sides.
5. Put a sheet of paper onto the beginning of the film.
In order to make it easier to insert the film, tape a sheet of paper onto the film and thread it through the
nip.
6. Inserting the film.
a. Insert the film around the guide roll, over the laminating roll according to the “FILM
INSERTING PLAN and its "Poly- out" or "Poly - in" illustration. Refer to the illustration
following this section.
b. Put the sheet through the gap between the laminating and pressure rolls so that paper will
be minimum 8 inches (200 mm) behind the contact surface of the rolls. ATTENTION! Follow
the safety rules for the Laminating and Pressure Roll Zone, Chapter 1.6.
7. Press the "PRESSURE UP" button.
The "PRESSURE UP" button can be pressed when a sheet of paper from the feeder and a sheet of
paper with film have gone between the rolls and you hold both sheets.
WARNING
Keep your hands and fingers at least 8 in. (200 mm) behind the nip point of the laminating and
pressure rollers. Failure to do so can cause severe injury.
8. Inserting paper with film in the separator.
a. Let two or three sheets go through the laminating section at the minimum speed.
b. Cut off the stuck sheets and put the film belt with paper between the separator rolls.
c. Turn the "Pull roller" switch to "Close."
9. Turn on the Knife and Snapping section.
a. When sheets are behind the snapping rollers turn switch for the knife in the position Start.

snapping rollers push the Snap Impulse button and sheet separation will start.
5.2 FILM ROLL POSITION ADJUSTMENT ON UNWINDING SHAFT
If you insert a new roll of film, which has a different width than the original one, proceed as follows:
1. Adjust the regulating nut of the film lateral movement (a) so that the front edge will be placed
with the the white line on the thread.
2. Turn the tightening nut on the conical holder (c) on the driving side to its initial position (i.e.
as close as possible to the conical holder) (e).
3. Loosen screw M8 on the conical holder (d) on the operator's side and take the cone out of
the unwinding shaft (b).
4. Check if the side of the film with adhesive is on the outer or inner film side. Depending on
film coating "POLY IN" or "POLY OUT," put the film reel on the unwinding shaft (b) as
specified in the previous illustration, "FILM INSERTING DIAGRAM."
5. Put the conical holder on the operator's side on and tighten the screw slightly. Support the
unwind shaft with a support (f).
6. Adjust the reel position according to the illustration below. The distance between the point of
the film reel and the support (f) is given by the size of the gap between the stack of paper
and the side plate on the operator′s side, plus the width of the edge of paper that is not
laminated.
Central position
c
b d
g
a
e
f
7. Tighten screw M8 on both conical holders.
8. Tighten the nut on the driving side so that the film roll will not slip on the conical holders
when the brake is applied.
9. Regulate the braking force of the unwind according to the film roll weight and speed of
laminating (g).
Each type of laminating film and adhesive have specific temperature range requirements. The required
temperature depends upon the thickness of the paper, line speed, film, humidity, ink coverage, type of
ink, and other factors. Testing of good film adhesion should be done before production occurs. The
laminating temperature range is 210 to 300 °F (100 to 150 °C).
5.4 PRESSURE MECHANISM
The pressure mechanism is important for correct adhesion. Depending on the desired final laminating
quality, it may be necessary to change the pressure of the pressure roll against the laminating roll. The
machine manufacturer recommends using a pneumatic pressure ranging from 0.2 to 0.6 MPa. The
pressure is adjusted with regulators I and II.
Regulator I Regulator II
The pressure can be adjusted separately on the left and right side of the pressure roll.
The pressure roller drops down:
• 20 seconds after pressing the “STOP” button (to stop the machine) on the control panel.
Problem: THE SHEETS ARE RAGGED ON THE SIDE BY THE SEPARATOR KNIFE
Solution: The problem is caused by:
- Too small gap between the sharp blade edge and guide pin
Two clamping screws M5 on the knives have to be loosened, the knife turned off the guide pins, and
then the screws must be tightened again.
If turning the knives will not resolve the problem, the knives have to be raised up by forming metal
sheet inserts 0.01 in. (0.3 mm thick). (Explanation on the knife position is given in Chapter 13.3.)
The main sections of the feeder are the lifting mechanism, table, feeder head, front guides, gate I, side
guides, in-feed wheels, and gate II. The feeder table is not removable. It is controlled by chains and
guided on two guide bars. The sheets are taken off the table and loaded in the machine by the feeder
head. During laminating, paper is taken off the top of the stack. The feeder head sensor checks the
stack height and controls the lifting mechanism. The feeder table is lifted automatically depending on
the paper withdrawal. One lifting step is 5/64 to 1/8 in. (2 - 3 mm). The movement of the feeder table is
either automatic controlled by the feeder head foot or by buttons on the main control panel. Refer to the
illustration in Chapter 4.1.
"STACK UP" (4) - the table will move up
"STACK DOWN" (5) - the table will move down
7.2 SHEET OVERLAP ADJUSTMENT
After any change of the sheet length, it is necessary to change the speed of the feeder head. This is
done by turning the regulator knob (t) manually.
Important
NEVER TURN THE KNOB IF THE MACHINE DOES NOT RUN.
Proceed as follows:
1. Start the machine.
2. Set the machine to a slow speed.
3. Set the arrow on the dial (u) with the manual knob (t) to the value, which corresponds to the
requested sheet length.
4. Check the sheetoverlap.
5. If a smaller overlap is required, turn the knob (t) slightly in the direction of the – arrow
(counterclockwise) shown on the sheet size label.
6. If a bigger overlap is required, turn the knob (t) slightly in the direction of the + arrow
(clockwise) shown on the sheet size label.
7. Wait untill 2 to 4 sheets are loaded after turning the knob (t) and only then adjust more. The
drive conversion unit is slightly delayed.
The side guides center the paper stack (c). They are symmetrically adjusted to the machine center.
There has to be slight clearance between the side guide strips and paper stack so that the strips will
not damage the paper and will not cause improper sheet feeding. The side guides are controlled by the
handle on the operator's side (d). The arrow (e) represents the turning direction if the side guides
position needs to be changed. If the sheet width is narrower, use –, if the sheet width is wider, use +.
The correct front position of a paper stack on the feeder is assured by the front guides (a) and gate I
stops (b). The sheets have to be pressed against the surface of the front guides. Be careful to prevent
paper bending, which could cause problems during feeding.
When a paper stack is loaded, press the "STACK UP" button. The table (f) will lift and its top position
will be determined by the capacity sensor (g). The paper pile should stop 15/64 in. (6 mm) from the top
of the gate I.
Loosen the clamp with the handle (a). Move the head to the rear position (off the machine). Lift the
table with a paper stack to the working position by pressing the "STACK UP" button. (See the
illustration in Chapter 4.1.) Move the head so that the rear stops (b) will touch the rear edge of the
paper stack slightly and then tighten the handle (a).
a
b
8.2 FEEDER HEAD ADJUSTMENT
The feeder head foot (c) has to be on top of the paper stack. Move the flat springs (d) onto the stack so
that their front edge will exceed the paper edge by approximately 5/32 to 9/32 in. (4 to 7 mm) and so
that they will be located by 5/32 to 15/64 (4 to 6 mm) above the stack. The height of the flat springs (d)
have to be adjusted so that separating the different sheets will be assured.
• The brushes (e) should exceed the paper edge by 5/64 to 7/64 in. (2 to 3 mm) and they should
sit on the paper only lightly to prevent blowing the paper out. (Use only brushes instead of flat
springs for a heavier paper weight.)
• Adjust the pipe blow (f) with the nut (g) so that 10 to 20 sheets at the top will be blown.
• Adjust the inner suction cups by deflecting the plot (ch) so that the paper sheets between the
suction cups will be tightened.
• Adjust according to the type of paper the vacuum that is necessary for the sheet intake by the
transport suction cups with the regulator. The regulator is located on the air compressor. Check
the vacuum value on the manometer (i). Refer to the photo in Chapter 8.3.
• The regulators (j) and (k) are used for adjusting the requested pressure of air for blowing the
sheets apart.
• The regulator (l) is used for adjusting the stack working height in the automatic mode.
When the width of a sheet is smaller than the pitch of the internal suction cups (m), it is necessary to
loosen the screw (n) and then to turn the internal suction cups forward by 90°. The suction cups will be
out of operation. Turning is also necessary in order to prevent hitting the outer suction cups on the side

8.4 SHEET FEEDING PROBLEMS
• Paper is not acclimated.
• Incorrect underpressure and pressure.
• Paper is not cut off due to a dull knife. The stack has to be shaken.
• The side pilers are clamped too tight. There has to be a small gap.
• Stuck suction cups. Remove any dirt or sediment and clean.
8.5 FEEDER HEAD PROTECTION AGAINST FEEDER DAMAGE
If the feeder head foot sensor fails, the table may keep moving upwards. In order to prevent the table
from hitting the feeder head, there is a sensor under the supporting arm at the guide bar of the feeder
head.
Gate I (h) holds the stack of paper vertical to the front edge. If the head moves forward, the gate I turns
down in order not to obstruct feeding the sheets into the machine.
The in-feed roller mechanism consists of weight rollers (a), accelerating rollers (b), upper guides (c),
and sheet overlap sensor (d).
e d
c a b
9.2.1 WEIGHT ROLLERS
The weight rollers are always in contact with the paper sheets and press them onto the in-feed roller.
Their position is set by the manufacturer and should not be adjusted. If the paper weight is higher, the
pressure on the loading rolls has to be increased. A set of weights (e) is provided for that purpose. The
pressure can be changed by removing or adding a set of weights (e).
The accelerating rollers are used to increase the pressure to the in-feed roller when the gate II turns
down. The mechanism is driven by the pneumatic roll on the driving side. The amount of pressure is
controlled by the control system and is set by the manufacturer. The position of rollers is set by the
manufacturer and the adjustment should not be changed.
The upper guides (c) hold the paper to the bottom guide plate so that sheets will not jump over the gate
II.
Position
There are three upper guides on the machine. The position of the center one is set by the manufacturer
and does not change. The position of the outside holders should be changed according to the paper
width. They should be adjusted so that they are approximately 13/32 in. (10 mm) from the sheet edge.
Loosen the screws (j) and then move them.
The sheet overlap sensor protects the supporting pressure roll and prevents the film from sticking to its
surface.
Check its function daily after the machine is turned on. To do this, start the machine and put a separate
sheet of paper between the receiver and sender of the SQ4 sensor. Remove the sheet. The machine
should stop and the message, "Missing sheets," will display on the operator's panel.
The sensor can be repaired only by a GBC service technician.
The function of the gate II (a) is to hold a sheet of paper and to release it so that the overlap of the
following sheets are within the tolerance of ± 1/16 in. (1.5 mm).
11. ADJUSTABLE GUIDE PLATES
The guide plates (a) prevent paper from folding. The guides form the paper before the laminating roll.
Their position can be adjusted by the screw (b) after loosening the nut (c). If a thicker paper is
processed, the plates have to be lifted so that the sheets will not deform.
Thick paper setting
b
c
If lighter weight paper is processed, the plates have to be tipped down to reform the paper.
The machine is equipped with a Becker T4.25 DSK rotary wing type air compressor, which has its own
documentation. The compressor works without oil.
Important
Do not position the compressor where water, oil, or any other liquids can enter the intake port.
After the compressor is connected to the machine, the first adjustment of vacuum should be set to 5.8
psi (40 kPa).
The air compressor can be turned on and off during the machine operation with the air compressor
switch (a), located on the control panel.
The pressure and vacuum valve should be adjusted according to the paper size and thickness.
Tightening the valve causes the air compressor to produce a maximum vacuum and pressure, which
increases wear and electricity consumption.
Any air compressor function problem must be repaired only by a GBC Service technician.
CAUTION
During compressor installation, ensure that the compressor rotates in the direction of the arrow on the
compressor casing. If it does not, a GBC technician must change the electric supply phase.
If a line is apparent on the laminated sheet, radius R3 of the decurling bar (a) can be used for thin
paper. The line is caused by the decurling bar edge.
To change the radius of the decurling bar:
1. Loosen the four M8 screws.
2. Turn the decurling bar (a) over end to end to the desired radius. R2 has a 5/64 in. (2 mm) radius and R3
has a 7/64 in. (3 mm) radius.
The pull rollers pull the paper between the laminating section and snap rolls in order to level the sheets
on the decurling bar.
Regulating the paper pull
The paper pull can be changed by altering the gap between the rolls with the regulating screw. The size
of the gap between the lower and upper drawing rolls is marked on the scale.
The continuous web of laminating film has to be nicked so that the sheets can be separated in the
snapping mechanism. A knife with an oscillating motion is used for this.
Turn on the “KNIFE” switch to the “START” position to start the knives.
Position of the knife mechanism according to the paper width
The snapping mechanism separates the individual sheets, which are connected by the laminating film.
Controlling the upper snap roll dropping
In order to get good separation, the gap between the snapping rollers on the operator side of the rollers
must close first before on the drive side of the rollers. The motion should look similar to a scissoring
type of motion. Adjusting the flow controllers on the pneumatic cylinders makes this motion.
Creating the paper wave in front of the snapping rollers
Snapping Roller thrust Skewing Wave on Directioning roller regulator wheel the paper safety screw
Separation of some films will improve with the use of the skewing wheel. Place the wheel on the drive
side of the paper and apply just enough pressure to create a 1/2 in. (10 mm) wave in the paper just in
front of the snapping rollers to separate the sheets.
The wave is made by adjusting the directioning roller on the edge of the paper band and with its
directioning in the path out of the machine. (Only a mild adjustment is enough.)
Optional skewing section
An additional skewing section can be mounted behind the snapping section to make sheet separation
easier for special films.
The laminated sheets, coming from the snapping section, accumulate on the stacking table.
MIN.
MAX.
14.2 STACKING TABLE POSITION ADJUSTMENT
The stacking table position must be changed according to the selected sheet size and paper thickness.
The table height can be changed at the front table clamps. To do this, remove the screw in the clamp
and reposition the table as needed.
Three possible
table positions
The incline angle can be also changed by adjusting the length of the legs. There are six adjustable leg
positions.
The machine is shipped on a wooden pallet. The machine position on the pallet is shown below.
Use only a forklift or pallet truck to transport the machine. The forks must be long enough to reach past
the pallet supports of the machine at the further end of the truck, as shown below.
When the machine is taken off the pallet, it is necessary to:
• Unscrew the clamping screws
• Put the forks of the forklift between the pallet and machine frame
Moving the machine off the pallet to the floor is illustrated in the following illustration.
A GBC service technician must install the machine, put it into operation, and train the operating
personnel.

roller heater has been turned off.
• Do not wear loose fitting clothes while you perform maintenance or adjust the machine.
• Use proper tools for maintenance and adjustment. Improper tools may cause injury.
• Use the eye protective shield while putting on springs.
• Maintenance and adjustment can be done only by a technician trained by GBC Service.
In the automatic operation the feeder table moves upwards in steps. When a new paper stack is
loaded, the table moves both upwards and downwards. To assure safe work, the following rules must
be observed.
Important
• The feeder lifting mechanism can be adjusted and greased only by a trained and responsible
person.
• Use the "STACK UP" and "STACK DOWN" buttons only for moving the table up and down.
• Grease the feeder head mechanisms only when the machine is stopped.
1.3 SAFETY NOTICES – MAIN DRIVE MAINTENANCE
The main motor drives, the feeder head, in-feed wheels, gate II, laminating roller, and drive
mechanisms are located opposite the operator’s side and are covered with a sheet metal cover. To
assure safe work, the following rules have to be observed.
WARNING
Obey the following precautions. Failure to do so can result in severe personal injury or damage the
machine.
• Cut the compressed air supply off to adjust the gate II and pressure roller mechanisms.
• The main drive mechanism can be adjusted by a trained person only.
1.4 SAFETY NOTICES – CHAINS AND BELT DRIVES MAINTENANCE

Important
• As far as maintenance is concerned, the chain lubrication and chain tightening are the only
allowed maintenance operations. Other maintenance and repair activities have to be provided
by GBC service.
1.5 SAFETY NOTICES – TWIN KNIFE MAINTENANCE AND CHANGE
The twin knife has a very sharp edge and therefore the following safety rules have to be observed.
WARNING
Obey the following precautions. Failure to do so can result in severe personal injury or damage the
machine.
• Use a 4 mm Allen wrench to adjust the knife position. The wrench can be put through the oval
holes at the upper part of the Plexiglas cover of the twin knife.
• Do not touch the sharp edges of the knives during adjustment or changing of the knives. The
knives can be held only away from the sharp edges.
• When handling the knives, put them in a safe place outside of the machine where no one can
get injured.
The solid safety Plexiglas cover must be installed every time when new or original knives are tested or
adjusted.
The feeder table is suspended on two roller chains and guided on two guide bars. Only a technician
trained by GBC Service can change or tighten the roller chains.
2.1.1 Chain Tension Adjustment
• The solid safety covers do not have to be removed for tightening the chains.
• Tighten the chains using the tightening screws on the feeder frame.
2.1.2 Chain Replacement
1. Disassemble the sheet metal safety covers.
2. Disconnect the chain from the tightening screws.
3. Take the old chain off.
4. Put a new chain on.
5. Connect the chain to the tightening screws and tighten the chains so that the table will go up
evenly in the horizontal position.
6. Install the sheet metal safety covers.
2.1.3 FEEDER TABLE TROUBLE SHOOTING
•The feeder table moves uneasily although a stack is not loaded.
Check the tighteness of the chains or tighten the chains properly. Clean or oil the guide strips.
•The automatic feeder table lifting is not working reliably.
The problem can be removed only by a GBC Service technician. Maintenance consists of
regular lubrication of the functional parts according to the lubrication plan and removal of the
excess grease and dust.
The feeder table is suspended on the roller chains (h) and driven by the electric motor with a gearbox
(j). The chain is clamped to the table on both sides. The torque from the motor is transferred through
the drive shaft on both sides of the lifting mechanism, which eliminates binding.
The feeder head is protected by a sensor from damage in the case of:
• The feeder head foot slides from the paper stack and the feeder table automatically rises up.
• The capacity sensor on the front of the paper stack fails.
The sensor is located under the feeder head and is close to the clamp.
If the sensor stops the machine for one of the reasons described above, do the following:
1. Switch the power off with the main power switch.
2. Remove 1 to 1-1/2 in. (25 to 35 mm) of paper from the top of the paper stack.
3. Check to see what caused the machine to stop.
The above procedure can be performed only by a technician trained by GBC Service.
If the sensor must be adjusted so that it will not prevent the normal function of the feeder head and will
stop the table movement just when the feeder head is slightly lifted around the guide bar after the
feeder (stack) hits the feeder head, the adjustment can be performed only by a GBC Service
technician.
2.5 ROTARY VALVE ADJUSTMENT
For correct feeding, it is necessary to precisely adjust the paper release from the suction cups. The
adjustment should be performed by turning the rotary valve (p). The release moment has to be 1/16 to
5/64 in. (1.5 to 2 mm) in front of the front dead center of the suction cup motion. The correct position of
the rotary valve is adjusted by the manufacturer and it is marked by a screwed hole in the hollow.
The adjustment can be performed only by a GBC Service technician.
The feeder head drive consists of the main motor (q) and the variator (r). The torque is transferred to
the head by the cardan shaft (s). Any adjustment can be done only by a GBC Service technician.

A section view of the accelerating rollers controls is shown below.
Maintenance should be performed as follows:
1. Disassemble the sheet metal safety cover.
2. Change the defective components.
3. Install the sheet metal safety cover.
The mechanism is driven by the pneumatic cylinder (f) on the driving side. The gate II mechanism is
controlled by the control system and is set by the manufacturer. The position of rollers is set by the
manufacturer and the adjustment should not be changed.
If the compressed air is cut off to the pneumatic roll (f), the spring (h) retracts the pressing roller so that
it does not contact and deform the feeding roller. Ensure that the spring is in good working order.
Only a technician trained by a GBC Service technician can change the pneumatic cylinders or
electromagnetic valves.
Pneumatic cylinder controlling the accelerating roller
Gate II is controlled from the pneumatic cylinder (b), which turns the lever (c) and therefore the whole
bar with the gate (a).

2.10.2 GATE II POSITION
The upper edge of the gate II must exceed the guide plate by 3/32 to 7/64 in. (2.3 to 2.7 mm). The
position is set by the manufacturer and can be adjusted only by a GBC Service technician.
The following should be performed by two people. To reassemble the pressure roll, reverse the steps.
1. Put two 1/2 x 2 in. x 4 ft. (10 x 50 mm x 1.2 m) bars under the pressure roller.
2. Disconnect the pneumatic cylinder pins from the pressure roller arms.
3. Unscrew the two pressure roller arm pivots from both arms of the pressure roller.
4. Roll the pressure roller with the arms from the front position to the gap between the
laminator and separator, and take them out of the machine.
2.14 SNAPPING ROLLER BELT
Assembly and disassembly can be performed only by a technician trained by a GBC Service
technician. If a belt fails, it must to be changed. The proper belt type is given in the parts catalog and it
is also printed on the upper surface of the belt. All the tighteners need to be loosened when the belts
are changed.
It is necessary to lubricate and inspect the different parts regularly in order to prolong the machine
function and life.
Weekly:
• Check the condensate quantity in the air treatment unit. If the condensate level in the
container exceeds 15/64” (20 mm), let some condensate out.
• Check if the covers are installed and all screws secured
• Check the correct function of sensors

WARNING
These buttons should only be used by service technicians for machine adjustment and for testing the
function of M1 and M2 motors. Do not use these buttons in any other way.
The displayed number of the actual value of the IRC encoder is used for visual control of the correct
function of this element. During the machine operation (the main motor is turning) it adds the number
up to the maximum value, then it resets and the action repeats.
The maximum number of the IRC encoder is the maximum caught number, which is proportional to the
paper format. This number will reset by switching the “SNAP IMPULSE” button off. It means that if the
format is changed to a smaller one, it is necessary to switch the “SNAP IMPULSE” button off and thus
the number will reset.
The machine error is signaled by yellow indicator ERROR (lit up continuously or blinking) and the
error/status message on the operator's panel in the right at the top. By touching this part of the panel,
you get to the Error Screen where the error/status is described in detail.

for the orientation check of this sensor.
• The error will reset as soon as temperature sensor ST2 shows the correct value. The error can
be suppressed by turning the heating off with the “HEATERS” rotary switch on the machine
control panel to STOP.
3.2.18 Error – temperature sensor Pt100 short – heating on the end sides
Status indication:
• Yellow ERROR indicator is lit up continuously.
• Operator's panel, Main Screen, 1st status line: ERROR
• Operator's panel, Main Screen, 2nd status line: Pt100 end side
• Error Screen:
Sensor of temperature
is short
- end sides
Status correction:
• The error is possibly caused by disconnection of conductors 511, 512 or of the connector
connection of these conductors. See DA-41-400n, sheet 4. Repair.
• A possible error of sensor Pt100 – ST2. Replace it.
• Note:
At 80 °F (25 °C) it is possible to measure the resistance of this sensor of approximately 110Ω
for the orientation check of this sensor.
• The error will reset as soon as temperature sensor ST2 shows the correct value. The error can
be suppressed by turning the heating off with the “HEATERS” rotary switch on the machine
control panel to STOP.
3.2.19 Status – the stacking unit attached to the machine is not running (it is stopped)
Note:
Applicable only in case a stacking unit is attached to the machine.
Status indication:
• START button/indicator is blinking.
• Yellow ERROR indicator is lit up continuously.
• Operator's panel, Main Screen, 1st status line: STATUS
Operator's panel, Main Screen, 2nd status line: Stacking mach.
Error Screen:
Stacking machine
is not running
Status correction:
• The attached stacking unit must be set into operation by pressing the “START” button before the
machine is started. Then the laminating machine can be started with the “START” button.
3.3 TROUBLESHOOTING – PROBLEMS ARE NOT INDICATED ON THE
CONTROL PANEL
3.3.1 Error – heating on the laminating roll is not active – end sides or middle
Possible indications of statuses:
• Bad laminated sheets quality
• A Part of the laminating roll is colder than the others
• The difference between the sections on the laminating roll was established by the contact
thermometer
Status correction:
• Check fuses FU1 (heating on the end sides) and FU2 (heating in the middle), if broken, replace
them.
• Check if no error is reported when rotary switch HEATERS is turned to position START and
contactor KM7 is activated. If not, the error is possibly caused by disconnection of conductors
1001, 215. See DA-41-100n, sheet 10.
• Check the correct function of power solid state relays A1 (heating on the end sides), A2 (heating
in the middle). If defective, replace them.
• The error is possibly caused by disconnection of conductors 503 - N, 506 - N or it is probably in
the connector connection of these conductors. See DA-41-400n, sheet 4. Repair.
3.3.2 Error – the snap roll is not turning while the machine is running and the SNAP
MOTOR rotary switch is in the START position
Possible indications of statuses:
The snap roll is not turning while the machine is running and the “SNAP MOTOR” rotary switch is in the
“START” position.
Status correction:
• Check circuit breaker FA2 if it is in position I. If not, set it to position I.
• The error is possibly caused by disconnection of conductors 312 - N, 313 – N, 314, 315, 316.
See DA-41-100n, sheet 3. Repair.
• The error may be caused by disconnection of conductor 909, which control frequency inverter
U2. Repair. See DA-41-100n, sheet 9.
• Frequency inverter U2 failed. Reset the error by the control unit or by switching the machine off
and on. More detail about the frequency inverter - see the Mitsubishi manual.
