Description / Specifications
Linear Knife Description
The SNAP Linear Knife is an add-on accessory for the SNAP 700 printer. It
mounts in place of the down stacker and in turn provides a mounting for the
down stacker.
The Linear Knife is designed to cut tag stock and stack into the down stacker. It
does not work with flimsy material such as care label tapes or pressure sensitive
materials.
The Linear Knife is removable if the other materials need to be processed on the
printer using the rotary knife. A training technician is required because the entry
into the printer electronics is required.

Installing Linear Knife – See Appendix A
See Appendix A for Linear Knife Installation Instructions.
Threading
To thread the stock through the SNAP 700 Linear Knife, bring the stock up
to the entry point of the knife. Once the stock comes in contact between the
upper and lower rollers, turn the feed knob clockwise. The stock will
traverse through the knife and exit out the nip assembly.
You will need to rotate both the printer feed knob and the linear knife feed
knob. The feed on the linear knife will not pull the material through the
printer. The feed in the linear knife is for take-up tension only.
Snap Linear Knife Installing Linear Knife – See Appendix A 9
Page 10
Maintenance
Cleaning Feed / Nip Rollers
The Linear Knife has a set of feed rollers that keep web tension between the
printer feed and the accessory knife. These rollers will need cleaning daily or
more often based on the materials being run,
1. Clean the rollers with isopropyl rubbing alcohol 70%. Do not use other
cleaning products as they may have a long term effect to roller life.
2. Turn off the power to the printer to clean any moving part to avoid
injury or damage to the printer
3. Apply the alcohol to a clean cloth and rub the rollers to remove any
surface build up. The rubber roller may become stained for contact
with the materials running through the printer. This should not harm
the roller or the material.
4. The rubber roller should be replaced at least once a year or before due
to ware or if the rubber starts to harden from age or UV lighting.

Warning: Follow knife adjustment procedure exactly
or damage will occur.
Warning: Turn off power to the printer to avoid
personal injury when adjusting, removing, or
replacing the knife assembly.
Replace the wheel blade when it becomes dull or nicked. The knife has a life
expectancy of 3 million cuts. Monitor the number of cuts through PCMate since
the printer does not have a cut counter. Stock both the wheel and stationary
blades to avoid down time in case of blade damage or jams.
Note: Replace both the wheel blade and the stationary blade as a set only.
Replacing only one can cause early failure of the blades.
When following the instructions below, use extreme caution as the blades are
very sharp.

Adjustments
Web Tracking in Center of Printer
NOTE: Cut quality and straightness requires the stock to track down the center of the printer because the Linear
Knife cuts across the web from both sides. Two settings adjust web tracking. The first setting is moving the web
front to back as controlled by the Feed Roller Assembly. The second setting is the position of the Web Guide
Assembly.
The Linear Knife makes one pass across the web for each tag cut. This means that if the knife starts its cut from
the near side of the web and the next cut starts from the far side of the web. The cut is done while the web is
moving through the printer. The knife has been designed when properly installed to be located in the center of the
feed roller assembly and the print head assemblies. If one or both of these setting are not correct the cut will vary
in width every other cut.
Setting the Web Tracking
Web tracking is the movement of the tag stock front to back in the Feed Assembly. To correct for this movement
there are four “Jack” Set Screws located on the inner mount bracket on the Feed Assembly. These will be adjusted
accordingly once the printer has been loaded with stock and run.
1. Load the printer with supplies (Stock & Ink) Make sure the tag stock supply roll is tight and the sides of the
roll are flat. If the roll is not flat it will track off the center of the print heads.
2. Leave the web guide open so the guides do not control the material moving through the printer.
3. Load the internal test format (see SNAP 700 user manual). The wide test format image will look like this.
The line running left to right should be in the center of the tag. The center of the line to the metal frame is
4” (101.6mm).
4. Start the printer, if the stock is walking toward the back of the printer, the outboard end of the Feed
Assembly needs to move toward the stacker. (Don’t worry if the knife cut is out of square, this will be
corrected later)
5. Loosen the three ¼-20 cap screws and turn the two left set screws 1/8 of a turn so that it will force the outer
end to move toward the stacker.
6. Snug the ¼-20 cap screws starting with the Upper right, then the lower, then the upper left.
7. Once all are snug, tighten the cap screws in the same order.
18 Adjustments Snap Linear Knife
Page 19
8. Run the printer again and see if there is a walking issue, if so repeat steps 4-6.
Loosen Screws
Use “Jack” Set
Screws to position
the Feed Assembly
one way or the other.
9. If the stock wants to walk toward the front of the printer, then position the feed assembly so that the outer
edge move slightly away from the stacker side, and reverse steps as previously stated.
10. Once the stock is tracking through the printer without walking, the feed assembly can be secured.
11. The Printer is now ready for the latest Operating System Installation. Download and install Operating
System Version 3.32.07.05 or later.
Setting the Web Guide
The web guide is located between the tag stock supply roll and the first print station in the web path. To set the
web guide correctly, get the tracking of the printer centered first. There are two set collars with thumbs screws
that will rest just off the material. Position these collars to steer the web correctly through the printer. Do not
try and force the stock more then 1/4” (5mm) as it can damage the edge of the tag stock.

1. Move the rotary knife carriage to the
center of the stationary knife.
2.
Adjust the inboard and outboard cam to
just barely touch the frame. Hold the came
in the desired position while tightening the
screws.
Knife Cam Adjustment
The cam adjustment keeps the frame from distorting during operation and
affects the cut angle slightly.

connectors on the daughterboard and
MCB.
Note: If the Snap 700 printer has the RFID
upgraded knife motor, be sure to
disconnect the motor connector from the
daughterboard. Having both knife motors
plugged in to the daughterboard will make
the Linear Knife motor fail.

Place the SNAP 700 back onto table.
Installing the Linear Knife – Mechanical Updates
The Linear Knife is ready to install on the printer. Position the printer where
you want to use the system. Relocating the printer with Linear Knife installed is
not advised as they are too heavy and not stable enough to move without
damage.
Installing the Lower Frame Support for the Linear Knife
46 Snap Linear Knife
Page 47
Installing Linear Knife onto the Lower Frame Support
4.
Position the knife unit so that it rests onto
the lower frame support. Position it so
that the extended bracket sits behind the
Feed of the SNAP 700.
The rear end of the mounting bracket
should be resting against the front cover.
NOTE: The knife will be centered to the
web path when the bracket is in contact
with the back cover. This is critical to
knife cut registration
5.
Install a ¼-20 x ½ Phillips Head Screw
through the SNAP 700 Feed and into the
Extended Bracket of the Linear Knife.
Be sure that the Knife is still resting on the
lower frame support.
6.
Line up the upper knife unit and the lower
frame support and secure with the
thumbscrew provided.

connected to the printer.
Snap Linear Knife 49
Page 50
1.
The nip assembly will be installed using
the same screws that mounted it to the
Printer.
2.
Place the top screw back through the
original mount hole and install the screw
but leave it loose by approx 3/8” (9mm).
Start the bottom screw but do not tighten
that screw as well.
3.
Push the nip assembly towards the frame
that it’s being mounted to and turn the
shaft to engage the drive with the driven
roller.
Installing the Nip Assembly
The nip assembly that was removed from the printer to make room for the new
knife will be installed on the Linear knife. Skip this section if the Linear Knife
already has a Nip Roller Assembly.
50 Snap Linear Knife
Page 51
4.
The nip assembly will be installed using
the same screws that mounted it to the
printer.
5.
Holding the nip assemble tight to the frame
with the drive engaged tighten the two
mount screws.
6.
Finished installed assembly.

1.
Remove the stacker mount on the back of
the stacker and replace it with the Stacker
Mount Block supplied with the Linear
Knife (P/N: 05627843).
2.
Slide the stacker onto the two shafts of the
knife assembly. The back of the stacker
must be in back of the nip assembly
stripper plate. This allows the cut tags to
fall into the stacker and not catch on the
stacker frame.
3.
Move the stacker’s back until the stacker
upright is approx 1/8” past the back edge
of the web.
Installing the Stacker on the Linear Knife
The stacker that was removed from the printer will be used on the accessory
knife.
52 Snap Linear Knife
Page 53
4.
Set the stacker platform angle with the
right end set as high as possible to begin
with. Once the stacker starts to fill with
tags a more desirable angle can be found to
provide a stack that can be handled to
unload.
The stacker may not be able to hold a full
stack of tags based on the tag being
stacked. RFID tags have a chip imbedded
in them so the tag is not uniform in
thickness. This will cause the tags to tip or
rock around. The number of tags cut and
stacked can be controlled by PCMate in
the format with a stop between batch
configurations.
5.
Plug the Stacker connector into the side of
the printer.
Plug power cord into wall and turn on
Printer. Note: The stacker will not work if
the Stacker Harness is not connected to the
Printer prior to turning on the printer.
