Thank you for purchasing a Dumor machine
This is a short instructions for the A4 and A3 card cutters.
What the machine will do
- Cut regular uncoated card stock from a A4 or A3 sheet into various length visit cards in 1 pass.
Limitations
(See diagram 1)
Paper is to be clean cut, no lip or hooking, square cut, even width and parallel sided, flat, no end curl.
Uncoated, unlaminated stock up to 350 gsm (A4 machine) or 320 gsm (A3 machine).
Working principle
The sheets are stacked in the infeed tray up to the load line.
(1)
see pictures at end of the manual
They are pushed forward to the front stop.
The machine is started.
The feeding wheels will move from home position
(2)
and rotate one turn, the cam
(3)
will raise the tray and engage the sheet
against the feeding rubber on the feed wheel
(4)
during the feeding part of the turn.
The single sheet will start to feed past the separator fingers
(6a)
(if the height is correctly set) and be engaged by the grey second-
ary roller.
(5)
The infeeding rollers will return to home position and stop with the cut off
(6)
facing the sheet so as not to drag/hold back the sheet
that is being fed in.
The lead edge of the paper passes over a IR cell
(7)
and sends a signal to the main-board that the sheet is on the way.
The machine then counts the start position of the sheet and calculates the stops at pre determined intervals to allow the cross
cutting blade
(10)
to cut the sheet into cross strips as selected by the user program.
The sheet then advanced under the slitting cassette
(8)
where it is slit into individual cards.
The cut off waste is deflected into a lower waste bin.
(9)
The cards fall into the reception tray.
The cross blade is a scissors type blade set
(10)
and is generally self sharpening and good for around 1.000.000 cuts.
The linear slitters
(11)
are also self sharpening and are generally good for 500.000 cards.
1- User set up
Mechanical set up
Setting the paper separation according to the caliper of the paper being run.
1 Set the separator finger gap
(6a)
to let only 1 sheet through at a time.
If the gap is too tight then the sheet will not feed.
If the gap is too large 2 or more sheets will feed in at one time and cause a
blade jam.
To adjust this there are:
2 knobs
(12)
on the front side of the machine that lock the tray in position;
loosen to free up the tray for adjustment.
They must be loose for next step to work or you will damage the levelling system.
Two Levelling screws
(13)
with red indicator needles to move the tray lower or higher; thus altering the finger gap to suit the card
being used.
Turn anti clockwise to lower the tray and increase the gap
Turn clockwise to raise the tray and decrease the gap
Twelve O’clock on the dial is the
zero
setting for 220 gsm paper
The adjustments are minute.
The adjustments have to be done equally on both sides.
The adjustment is correct when only 1 sheet will feed through at one time.
