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.
