Start Up
Important: During warm up, the coating roller gets heated up by the adhesive. It is very
important that the level of the adhesive be above the “full” block (top block, located in the
left side of the tray). If the adhesive is too low, the warm up will take longer and the roller
will have trouble turning.
Connect the machine to an approved outlet and switch the machine on by using the red
‘Power’ button mounted on the rear of the machine.
Warm up time is normally 55 minutes. When the machine has reached the correct operating
temperature the ‘ready’light on the front of the machine will illuminate. The motor can now
be switched on allowing the coating roller to turn. When switching on the motor, always
allow the roller to turn for 20 seconds to help it reach the correct operating temperature.
Adhesive Type
MXII Adhesive
Formulated for book covers and any application where a tight fold back and extra strong
adhesion is required. This adhesive never dries out so can be used at any time after coating and
sticks to almost any surface. Not suitable for products that require guillotining after gluing.
The MXII adhesive runs better at a lower temperature and a usual setting for this is with the
knob at the 12:00 o’clock position.
RP Adhesive
Formulated for any requirement where flat surfaces are to be glued together. Provides a stiffer
bond on flexible products and allows some re-positioning, especially if left open for a short
time. Will cure out over time and greatly reduces sticking to your guillotine blade.
This adhesive generally runs better at a higher temperature with the knob set around the 1:00
o’clock position.
Applying adhesive
The Maxit adhesive is very strong, so for most lightweight stocks or photographic papers
you only need a very thin coating. For textured or thicker stocks, such as canvas, you would
need a heavier coating.
Feed and catch leading edge Guide longer prints towards front

Page 6
1. Turn on the motor switch located at the front of the machine. Feed the print in with one
hand and catch it as it comes out with the other hand. Do not let the print drop down as it
exits. Turn off the motor after coating the print. Note: the motor should not be left running
for more than five minutes at a time or it will overheat and cut out. The motor will only start
to operate again when it has cooled down.
2. For longer prints, such as posters, take the leading edge as it exits and guide the print
back towards the front of the Maxit. The small upper roller is also driven and will assist with
guiding the poster back towards the operator.
Stock type
Ink Jet photo paper
Most photo paper has a resin coating on the back and should be run at a slightly lower
temperature. If the temperature is too high the heat will affect the resin coating. This will
cause the photo paper to stick to the roller and go under the stripper fingers. If you
experience this adjust the temperature knob from the 12 o’clock position to the 11 o’clock
position. You will then need to wait 25 minutes for the temperature to drop.
Lightweight paper
You should use a minimum stock of 60gsm and for thin papers should apply a thin coating
and set the temperature slightly higher. If the paper is too thin, it will receive cut marks from
the stripper fingers at the rear of the coating roller.
Mounting
After coating your print, MX adhesive will not dry out, so you can mount your print at any
time. However, with RP adhesive the substrate must be mounted within 2 minutes or
adhesion may be affected. The adhesive will stick to most surfaces including plastic, metal
and wood. After rolling down your print, you will immediately receive a permanent bond.
Maximum adhesion will be achieved after 24 hours.
Roll down print to substrate Place silicone release paper on
board to mount larger prints.
For smaller prints, simply line up the print on your substrate, then roll it down to eliminate
air, ensuring it makes proper contact with the substrate.
When lining up large prints place the board or other substrate on the table and place silicone
release paper on top of the board leaving the top two inches uncovered. The silicone paper
will keep the print from sticking while lining up the print. Then roll down the print to the first
two inches and slide down the release paper as you roll down the rest of the print. Save the
silicone release paper and use it as many times as needed.
To further improve bonding for RP adhesive, pass the glued sheets through a laminator,
pressure roller system or hand roller to ensure a permanent bond is achieved.

Adding Adhesive
Maxit adhesive comes in pellets which normally stick together in the bag. Either cut the
required amount with a knife or alternatively, refrigerate the product for approximately 2
hours. It is then easy to tear off the adhesive in the pieces you require.
When the adhesive level drops to the ‘add level’add more adhesive. It is important to
maintain the adhesive level at, or above, the ‘full’ level. If not, you will not achieve the
correct coating and it will take longer to warm up in the morning.
Add adhesive Bag dissolves too!
Pull down the front cover. Place approximately half of the adhesive pellets in the front of the
tray. You do not need to wait for the pellets to melt before using the Maxit. The bag is made
from a special material and is dissolvable in the hot adhesive.
Cleaning
Remove side screws Slide out top half of covers
Swivel top roller back
WD-40, although a lubricant, is excellent for cleaning adhesive from the outside casing. If
adhesive appears on the top roller, remove the screws from the sides of the Maxit, slide off
the top halves of the covers and swivel back the top roller. Then use WD-40 to clean it.

Adjustments
Loosen screws on top Adjustment screws at the front
Coating thickness: The coating thickness can be changed by adjusting the wiper blade.
Loosen the screws on top of the blade and then turn the two adjustment screws in front of
the blade. Clockwise will reduce the coating and counter clockwise will increase the coating.
These screws are a fine adjustment and need only small movements. Ensure you do not
adjust the blade against the coating roller or damage may occur.
When retightening the screws on top, ensure that the adhesive strippers (left and right)
are pressed against the roller ends and shaft otherwise there is a risk of adhesive leaking
into the machine. Left hand of the machine is shown in the picture below.
Temperature: There is a knob which adjusts the temperature of the adhesive and is located
under the front cover. If the coating is too sticky, you can turn the temperature up slightly
which will thin out the coating. If smoke starts appearing from the adhesive in the tray, then
the temperature is too high and it should be turned down.
Patchy coverage
If not set correctly, the Maxit can produce adhesive coverage that is patchy and not 100%. If this
happens, please check the following and make the necessary adjustments;
1. There are two triangle steps in each corner in the back of the tray and the full level in
front. They are all the same height. To see if it is level left to right, look at the adhesive
level versus the two triangle steps. To see if it is level front to back, look at the level
versus the triangles and the full step in front. If need be, place shims under the feet at
the bottom of the Maxit to level it out. Even if it is at the full level, add some more
adhesive so it is about 1/8" above the full level.

Page 9
2. Adjust the operating temperature:
MX Adhesive - If the knob is at the 12 o’clock position; turn it to 11 o’clock and if at the
1 o’clock position turn to 12 o’clock. Allow approximately 30 minutes for the machine
to achieve the correct new temperature.
RP Adhesive - If the knob is at the 11 o’clock position; turn it to 12 o’clock and if at the
12 o’clock position turn to 1 o’clock. Allow approximately 30 minutes for the machine
to achieve the correct new temperature.
3. Also it is important to keep the entire coating roller hot. Consequently, when you first
start using it in the morning or if you have not used it for a while during the day, turn
on the motor for 30 seconds before you use it to get the roller hotter.
4. If you are using it to coat multiple prints, then leave the motor running and you will find
any stringiness should be reduced or eliminated. Also make sure you keep the adhesive
level up to keep the roller hot. The adhesive should not come off on your fingers and
will not at the correct temperature.
Trouble Shooting Guide
Start Up
Issue: The ready light will not come on after 55 minutes, so the motor will not run even though
the adhesive is melted.
Cause: This is very rare, but can happen the first time you use Maxit due to a thermostat in the
machine being impacted during shipping.
Solution: A slight adjustment is needed on the motor thermostat. Contact your local dealer and
they will email you the instructions. Once you make the correct adjustment, you should not
need to do it again.
Issue: The adhesive is melting, but not getting hot enough.
Cause: Not enough power coming into the Maxit due to too many items plugged into the same
outlet or using a poor grade extension cord. Also, make sure the temperature knob has not
been moved to the left, lower than the 11:00 position.
Solution: Remove other items from outlet. Also see if you can plug directly into outlet instead
of using the extension cord. If you must use a cord, it needs to be heavy gauge.
Issue: Smoke coming out of adhesive in tray or very strong odour.
Cause: The Maxit is running too hot. It is not unusual for the Maxit to run hotter in your
premises than in our quality control room due to voltage variations. Also, running the motor for
long periods of time will heat up the adhesive significantly.
Solution: turn the temperature knob slightly to the left. If you are at the 1:00 position, turn it to
12:00. If at 12:00, turn to 11:00. The Maxit takes around 30 minutes to reset the overall
temperature.

Coating problems
One of the major reasons for poor coating is the adhesive being too low in the tray. There are
two steps in the front, left of the tray with the bottom step being the “add” level and the top the
“full” level. You must keep the adhesive well above the add level and up to the “full” level as
much as possible. This is the first thing you should check.
Issue: The first ½ of the paper comes out with a good coating, but the last ½ is streaky.
Cause: The adhesive level in the tray is too low. Also your coater may be on an unlevel surface
so the back of the machine is higher than the front. The adhesive level in front looks full, but
there is less adhesive in the back under the coating roller so it does not pick up enough
adhesive.
Solution: Level the front of the coater by placing shims under the front feet
Issue: Small misses in the adhesive coating on the back or some streaky areas in the coating.
Cause: The Maxit is running too hot. When running too hot the adhesive is less tacky so the
paper does not hug the roller well and does not pick up the proper amount of adhesive.
Running too hot also thins out the adhesive on the coating roller.
Solution: Turn the temperature down slightly to the left. If the knob is at the 12:00 position,
turn it to 11:00 and wait 30 minutes for the temperature to reset.
Issue: Receive a thin straight line of missed adhesive in the direction in which you are coating
the paper.
Cause: There is dirt or debris lodged between the wiper blade and coating roller and is blocking
the adhesive flow.
Solution: Loosen the screws on top of the wiper blade and use the two set screws in front of
the blade to bring the blade back, away from the roller. Clean out any dirt in the blade area. If
the blade is very dirty, you may want to remove it to clean it.
Issue: The paper comes out of the machine with “score” lines on the image side.
Cause: The paper is too thin, so it hugs the coating roller then goes over the stripper fingers
which marks it with lines.
Solution: Use heavier gsm paper. The minimum recommended weight is120gsm. With photo
paper minimum is 9 mils. If the paper is borderline, then you may be able to eliminate the lines
by increasing the temperature and thinning out the coating using the wiper blade.

Page 11
Issue: Coating is too thick or too thin
Cause: Position of wiper blade
Solution: Reset the blade using the instructions on Page 7of this operating guide.
Issue: Getting drops of adhesive on the leading edge of the paper.
Cause: Adhesive is building up on the leading edge of the stripper fingers after running the
motor for a while.
Solution: Turn off the motor for a minute and the drops should melt away. Also space the
fingers so there is the minimum amount needed under the paper. Reset the blade to produce a
thinner coating.
