1. Install the TR-10 Reel Assembly on
the machine by hooking the rear
bracket to the center tie bar of the
head assembly. Pivot the reel
assembly forward to seat the front
bracket over the front tie bar of the
head assembly.
NOTE: In order to run the stamp at a
position within 1/4” of the edge of
the media, install the 90-103-02B
Right Side Guide supplied with the
machine. This guide will permit the
positioning of the stamp at the top
edge of the media.
2. To position the reel, slide the whole

LABEL SENSOR ADJUSTMENT
THE L-250/350 HAS BEEN FACTORY CALIBRATED TO DETECT THE PRESENCE AND
ABSENCE OF LABELS UNDER MOST CONDITIONS. HOWEVER, WITH THE
VARIATION OF BOTH LABEL AND BACKING PAPER DENSITY, IT MAY BECOME
NECESSARY TO FINE-ADJUST THE SYSTEM.
1. Locate the LABEL SENSOR
ADJUSTMENT knob [Figure
9A] and red light emitting diode
[Figure 9B] on the non-operator
side cover. Turn the switch fully
COUNTER-CLOCKWISE to
position 1.
2. Thread labels/tabs/stamps into
the labeler following the
diagram [Figure 5 or Figure 8].
3. Turn the LABEL ADVANCE
[Figure 3D] knob until the first
label (or tab) just starts to peel
off the backing paper.
4. Turn the LABEL SENSOR
ADJUSTMENT [Figure 9A]
knob CLOCKWISE until the red
L.E.D. is illuminated.
5. Release the label pressure
roller (turn it off) and pull the
label material approximately
two inches out of the machine.
This ensures the backing paper
is the only part, which is seen
by the label sensor. The red
L.E.D. will not come on at this
time.
6. Turn the LABEL SENSOR ADJUSTMENT knob CLOCKWISE and count the number
of clicks the switch makes until the red L.E.D. comes on.
7. Now turn the switch COUNTERCLOCKWISE half the number of clicks that you
counted.
EXAMPLE: the light comes on at the sixth click. Now remove the tab from in front of
the sensor and turn the switch six clicks CLOCKWISE. The light comes on again. Now
turn the switch three positions back or COUNTERCLOCKWISE.
THE SYSTEM IS NOW CALIBRATED TO THIS TYPE LABEL.
THIS STEP CONCLUDES THE INITIAL SETUP AND ADJUSTMENT PROCEDURES.

OPERATING INSTRUCTIONS
1. After setting up the L-250/350 (see Setup Instructions), place a stack of envelopes
between the envelope guides.
2. Pull out the receiving tray one-inch more than the length of the envelope.
Note: If using a conveyor; slide out and remove the receiving tray.
3. Turn the speed control knob [Figure 10D] to minimum and press FEED switch [figure
10F]
4. Observe how the envelopes are feeding. If they are skewing, readjust the stripping
device [Figute2D]. Press the FEED switch again. The L-250/350 will stop. IF THERE
IS AN ENVELOPE BETWEEN THE EXIT ROLLERS, REMOVE IT SO IT DOES
NOT COVER THE MEDIA PHOTOSENSOR.
5. Set the LABEL POSITION switch to desired setting. Each position of the left switch
Figure 10A] moves the label 1/2". Each position of the right switch [Figure 10B] moves
the label 1/32".
NOTE: Any attempt place labels at a distance greater than the length of the envelope will
cause the labeler to feed media without affixing labels.
6. Make sure there is a label [Figure 11A] visible by the peeling mechanism of the
labeler [Figure 11B]. The photosensor that senses the presence of a label is located
Figure 10

-10-
at the edge of the peeling mechanism. If the sensor does not see the label, any
attempt to run the labeler will result in failure to feed the media. A flashing light
indicates labeler is out of labels.
7. Depressing the LABEL switch [Figure 10E] will activate label-affixing circuitry in the
labeler. The yellow indicator light should be on. Depressing the FEED switch [Figure
10F] will activate feeding mechanism and labeling process.
8. Adjust speed to desired setting by turning the speed control knob [Figure 10D]. Add
envelopes to the labeler as needed. To stop the labeler, depress the FEED switch.
9. DO NOT FORGET TO REMOVE ENVELOPE FROM BETWEEN EXIT ROLLERS
PRIOR TO ACTIVATING LABELER.
10. If the labeler runs out of envelopes, it will automatically stop after a few seconds. The
green light in the FEED switch will start flashing indicating an OUT-OF-ENVELOPES
condition. Depress FEED switch to reset labeler. Load envelops between the guides
and depress switch to start the labeling process.
11. If there are no more labels, or, if two or more consecutive labels are missing, the
labeler will stop and the yellow LABEL OUT indicator light will flash.
12. The counter (H. Fig. 8) will advance one count with every label placed on an envelope.
It will only count when LABEL ON switch is activated. Maximum count is 99,999. To
reset the counter to 0, depress the COUNTER RESET switch (1, Fig. 8).
ZIP-SORT
With the ZIP-SORT switch ON [Figure 10C], the machine will stop every time a missing
label is detected. To activate this feature, manually remove leader label from each zip
code or carrier route prior to loading labels onto the labeler and slide the ZIP-SORT switch
to the ON position. Operate the labeler in the usual manner.
When a missing label is detected, the labeler will stop and the LABEL OUT indicator light
will flash. Depress the FEED switch to reset the machine, and, using the LABEL
ADVANCE knob, bring the next label to the peeling mechanism. Separate the labeled
pieces. Depress the FEED switch again to resume labeling.
WARNING
NEVER LEAVE THE L-250/350 WITH POWER ON FOR
A PROLONGED PERIOD. DAMAGE TO INTERNAL
COMPONENTS MAY RESULT!

USING AN OPTIONAL CONVEYOR WITH THE L-250/350
Warning: Before connecting a conveyor to the power outlet on the L-250/350, please be
sure it meets the following electrical specifications: 115 VAC and a maximum current
draw of 1 amp or less.
1. Slide out and remove the receiving tray. Position the conveyor against the labeler.
2. Plug the power cord from the conveyor into the conveyor receptacle on the rear of
the L-250/350. Turn on the conveyor’s power switch. The conveyor will now be
stopped/started by the tabber/labeler.
3. Depress the FEED switch on the labeler. The conveyor will start working. Depress
the FEED switch again and the conveyor will stop.
INSTALLING THE OPTIONAL TR-10 REEL ASSEMBLY
The reel assembly will allow the machine to utilize tabs supplied on a roll instead of the
standard fan-folded tabs. This assembly will also allow the L-350 to utilize stamps
supplied on a roll. The major benefits of this are fewer threading cycles as a roll can hold
as many as 10,000 tabs.
1. Remove the standard label feed tray.
2. Mount the reel assembly to the machine by hooking the rear bracket to the center tie
bar of the head assembly.
3. Pivot the reel assembly forward to seat
the front bracket over the front tie bar
of the head assembly.
4. To position the reel, slide the whole
assembly on the tie bars until the
tracking guides [Figure 11A] are over
the desired tabbing area.
5. Lock the reel in place with the
thumbscrew [Figure 11B].
6. Remove the reel support guide [Figure
11C] by pulling it off the reel shaft.
7. Mount a spool of tabs so it unwinds in a
COUNTER-CLOCKWISE direction with
tabs facing up. Reinstall the support
guide removed in step 6.
8. Route the tab supply around the brake
roller [Figure 11D] to the guide roller
[Figure 11A] in such a manner that the
tabs contact the brake roller while the
backing paper contacts the guide roller.
9. Loosen the two tracking guide screws and separate the guides.
10. Route the tab supply between the guides and clamp support rails.
Figure 11

-12-
11. With the tabs feeding straight through the clamp, move the two tracking guides
[Figure 11A] into contact with the backing paper edge.
Tighten the red thumbscrews.
12. Complete the tab routing through the sensor assembly, around the peel bar, through
the pressure rollers, and into the take-up roller split shaft see Figure 8 in this manual.
13. Center the sensor on the tab supply.
OPERATING HINTS
1. Fan out the envelopes before loading them into the tabber/labeler.
2. After loading the envelopes, tap the stack lightly to keep it straight between guides.
3. If doubles occur, check the stripping device for proper pressure setting.
4. Straighten out excessively curled envelopes.
