Verify Latch Operation:
- Open and close the printhead assembly, verify that the latch is fully engaged. If you are unable to get
the printhead to latch, the side plate is too low.
- Pressing down on the printhead assembly should not cause the latch to loosen or reveal any gap at the
latch point. If there is a gap or movement in the latch then the side plate is too high.
- Print some sample labels. If degraded print quality or ribbon tracking problems are observed then the
side plate is not positioned correctly.
Step 3: Installing the Peel & Present Mechanism
Position the Peel and Present Mechanism
for mounting on the front of the printer.
Tighten the Mounting Screw to secure
the mechanism to the printer.
This completes the installation process.
Proceed to Loading Media to begin use.

Loading Media
With the Peel and Present option, labels printed in a batch will be automatically be separated from the
backing material and dispensed “on-demand”– that is, printing will occur only after a previously printed
label has been removed from the printer.
Press in the Latch to open the mechanism.
Swing the mechanism open.
Load the printer with media (see the
Operator’s Manual for detailed instructions). Latch
Load media into the printer as you normally
would for tear-off operation (see the
Operator’s Manual for details), however,
extend an additional 12 inches (30 cm) of
media out the front of the printer.
From this 12 inches (30 cm) of media, remove
all of the labels, so that only the Backing
Material remains.

Note: The Media Retainer can be used in place of the Media Clip for a more consistent rewound roll. The Media
Clip and Media Retainer cannot be used together.
Put the leading edge of the Media into a Slot on the Internal Rewinder and insert the Media Clip. Be
sure the leading edge of the Media is cut square and that is inserted evenly into the slot.
Manually rotate the Internal Rewinder to remove slack from the Media.
Plug in and turn ‘On” the printer. After initialization, press the FEED Button to align the next label to
the top of form position. (If a peeled label is presented, remove it to proceed.) The printer is now ready
for on-demand use.

Setup, Configuration, and Operation
The Peel and Present option is plug and play; no setup or configuration is required. As soon as power is
applied, the printer senses and enables the Present Sensor for operation.
During operation, when a label is present (blocking the sensor), the yellow Stop Light on the front panel of
the printer will flash to prompt you that a label awaits removal.
With printers equipped with an LCD display, the display will read “REMOVE LABEL”
Notes: (1) The operation of the Present Sensor can also be controlled via software commands from the host. Be
sure that your software program is properly configured for use with this option. (2) If the Present Sensor is
disconnected without first powering off the printer, the printer will behave as if there is a label blocking the
sensor. Turn the printer off and then back on. The printer will reconfigure itself to operate without the
Present Option
Unloading the Internal Rewinder
When the Internal Rewinder becomes full remove the Media Clip. Grasp the used backing material and
pull it from the Internal Rewinder.
Note: Never allow the outer diameter of backing material to exceed 4 inches (102 mm) on the Internal Rewinder.
Periodic Maintenance
The Peel Mechanism Rollers will need to be disassembled and cleaned approximately every 100,000
inches to ensure trouble free operation. This cleaning interval may be more or less depending on the type
of adhesive on the back of your media. Heavy or “gummy” adhesive will require more frequent cleaning.
