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.
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.
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, 10 Maintenance 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.
Knife Blade Replacement 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.
3. Remove the six 8-32 Button Head Screws and remove the left and right side covers. 4. Remove the entry guide and deflector bracket by swinging the carriage assembly out and inserting a 2.5mm Allen Key or ball driver through the holes in the frame to gain access to the screws. Note: The upper sensor shaft is not shown for clarity purposes. 5. With the entry guide removed, see the four exposed Phillips flat head screws holding the upper stationary blade.
6. Removing the upper stationary blade allows access to the wheel blade. Remove the wheel blade, bearing, and spacer. Replace the new parts in same order as removed and shown. Note: Be careful not to move the carriage assembly too much as the wheel blade will fall off. 7. Re-install the upper stationary blade with the four flat head screws removed from step 5. Be sure the wheel blade is behind the Stationary Blade and that the stationary blade is oriented so that the cutter edge is down. 8.
9. Re-install the covers and knobs.
Knife Blade Cleaning When the material starts to have poor cut along all or part of the cut edge, the knife blades will need to be removed and cleaned. Note: When cutting RFID tag stock the knife may need to be cleaned every 25,000 cuts depending on the adhesive layer used to construct the tag material. This may vary in frequency base on the supplies. The knife blades will need to be taken apart as surface cleaning is insufficient. Warning: Follow knife adjustment procedure exactly or damage will occur.
3. Remove the six 8-32 Button Head Screws and remove the left and right side covers. 4. Remove the entry guide and deflector bracket by swinging the carriage assembly out and inserting a 2.5mm Allen Key or ball driver through the holes in the frame to gain access to the screws. Note: The upper sensor shaft is not shown for clarity purposes. 5. With the entry guide removed, see the four exposed Phillips flat head screws holding the upper stationary blade.
7. Re-install the upper stationary blade with the four Phillips flat head screws removed from step 5. Be sure the wheel blade is behind the stationary blade and that the stationary blade is oriented so that angle is down. 8. Re-install the deflector bracket and entry guide. 9. Re-install the covers and knobs.
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.
8. 9. Run the printer again and see if there is a walking issue, if so repeat steps 4-6. 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. Loosen Screws Use “Jack” Set Screws to position the Feed Assembly one way or the other. 10. Once the stock is tracking through the printer without walking, the feed assembly can be secured. 11.
Knife Cam Adjustment The cam adjustment keeps the frame from distorting during operation and affects the cut angle slightly. 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.
Web Tracking Adjustment If the web is tracking through the SNAP 700 printer but is not tracking into the Knife square, there will be a buckle in the web. The tracking can be adjusted by rotating the thumb wheel on the Linear Knife located on the inboard side of the Knife. Buckle in Rear of Knife (Needs to be adjusted, cut will not be square.) Web tracking straight (No buckle) Ready to move to the next step Buckle in Front of Knife (Needs to be adjusted, cut will not be square.
1. Loosen the ¼-20 cap screw shown. Rotating the thumb wheel will rotate the knife in one direction or the other. 2. Rotate the thumb wheel toward the operator to move the outer edge of the knife to the left. 3. Rotate the thumb wheel away from the operator to move the outer edge of the knife to the right. After the knife is in the desired location, tighten the ¼-20 cap screw.
Adjusting the Sensor The SNAP 700 Linear Knife has the capability to sense through hole, slot, top reflective, or bottom reflective sense marks. The sensors are assembled so that the sender and receiver are opposite each other. See instructions below to line up the sensors if they need to be re-aligned. 1. Remove the feed knob and the sensor adjust knob. 2. Remove three 8-32 button head screws and the left side cover 3. Temporarily re-install the sensor adjust knob.
4. Remove the Phillips head screw securing the idler gear standoff shown and remove the standoff with gear so that the top and bottom sensor do not traverse together. 5. Rotate the sensor adjust knob so that the upper sensor travels directly over the lower sensor. This will ensure the sensors are in the correct location with each other. 6. After the sensors are directly over each other, remove the sensor adjust knob from the end of the shaft.
7. Re-install the idler gear removed from Step 4. 8. Re-install the left side cover and secure with the three 8-32 button head screws. 9. Re-install the sensor adjust knob and the feed knob.
Positioning the Sensor To position the sensor correctly for a thru-hole format, the web must be tracking through the printer and knife correctly. If not, see the section in this manual on web tracking. The center of the sensor block will need to be slightly off center to the hole that is being sensed. 1. Load supplies on and through the printer and knife and be sure the web is tracking correctly. Sense-Hole Move the sensor in the proximity of the hole that is in the web. 2.
sensors” and begin to run. If the sensor is not in the correct position, the printer will stop. Traverse the sensor over the hole so that the screw on the sensor is just to the left of the hole in the stock.
3. Start the printer back up, as the stock passes through the knife, the supply light on the 700 should light up each time the sensor senses a hole. If the printer stops and gives another sense mark error, repeat step 2 to move the sensor slightly.
Centering the Knife to the Web After the web is tracking through the printer and into the knife straight, it may still need to be centered going into the knife. 1. Turn off power to the printer. Unplug the stacker and remove it from the linear knife. Unplug the Linear Knife from the Snap 700 printer. 2. Remove the feed knob and the sensor adjust knob. For clarity purposes the knife if shown not attached to the printer. These instructions are stepped as if the knife was attached to a printer. 3.
4. Loosen the thumb screw holding the upper and lower halves of the Linear Knife together. Loosen the lower right 10-32 E-S Nut mounting the knife pivot bracket to the main frame. The other three nuts are just tight enough to be able to slide with a Belleville washer. 5. Insert a flat blade screwdriver into the triangle and rotate left or right depending on which way the knife wants to move. 6. With the hex nuts loose, the bracket will now slide front to back.
7. Tighten the E-S Nut and the thumbscrew. 8. Feed the web through the knife and run some sample labels to see if the web is centered through the knife. 9. If web is not centered, repeat steps to take off upper half of knife and move mounting bracket to a more desired location. Repeat until there is the same amount of distance between the edge of the rollers and the sides of the web.
10. Once the web is centered, remove the web from the Linear Knife and remove the feed knob. 11. Install the left cover and reinstall the feed knob and the sensor adjust knob. 12. Thread the Linear Knife and run samples to check centering of the web.

Appendix A The SNAP 700 Printer will need minor alterations to have a Linear Knife installed. These alterations apply to both a new printer and a field installation. For new printer installation, see instruction “Installing the Linear Knife” and “Installing the Stacker on the Linear Knife”. For field installation, replace the original equipment rotary knife by beginning below. NOTE: Avoid personal injury or damage to the electronics in the printer by turning off the printer and disconnect the power cord.
Removing the Nip Assembly The Linear Knife will use the existing nip assembly and mount hardware from the printer. 1. The nip assembly is removed with a long #2 Phillips screw driver. Loosen the two 10-32 X ¾” Phillips head screws that mount the assembly to the frame and then remove the two screws. 2. Save the nip assembly and the two screws. They will be used to remount the assembly to the new linear knife.
Removing the Knife Assembly The Linear Knife has its own feed and will reuse the existing printer nip assemblies. The standard rotary knife assembly needs to be removed from the printer. Save this unit to convert back to a standard printer in the future. 1. To remove the knife loosen the two ¼”-20 x ½” cap screws using a 3/16” hex tool. 2. Retain the knife and screws for any future needs. These are not part of the new knife accessory.
3. Remove the feed / knife tie bracket. There are two 10-32 x1/4” Button head screws to removed using a 1/8” hex tool. 4. Printer is ready for the new knife to be installed.
Removing the Rear Cover 1. Turn off the power to the printer at the end of a batch so not to lose downloaded data and disconnect power cord. 2. Unplug all peripherals such as stacker, remote display, verifier, etc. Unplug power cord from wall outlet. Remove the stock and ink. Remove the back cover of the printer by removing (10) button head cap screws using a 3/32 Allen Key or T-Handle.
Installing the Linear Knife - Electrical Updates Replace the Motherboard Entry On field upgrades to the SNAP 700 printer, the motherboard entry bracket may need to be replaced. See the steps below to replace the entry bracket. A new SNAP 700 printer with the Linear Knife installed will already have the motherboard entry bracket installed onto the Snap 700 frame. 1. Label each connector to the MCB with the appropriate plug name printed on the board. Remove the connector from the board after labeling it. 2.
4. Remove the six screws holding down the motherboard. 5. Slide the motherboard back and out of the way to expose the three screws mounting the motherboard entry bracket. Remove the three screws. . 6. Pop out the motherboard plate from the opening and save to re-install into the new entry bracket.
7. Remove the last two screws holding the motherboard entry bracket to the base frame. Remove motherboard entry bracket. 8. With the motherboard entry bracket removed the printer should look something like this… . 9. Install the new motherboard entry bracket (with the 5 existing screws) back into the same place the old one was removed. Notice the new bracket now has three accessory openings for mounting harness connectors.
11. Slide the MCB upright back into the slot on the motherboard. 12. Install the screws mounting the upright bracket to the motherboard entry tray. . 13. Secure the upright bracket to the rear frame with the existing hardware as shown. 14. Reinstall all connectors to the MCB from the labels attached to each harness applied in step 1.
Install Internal Harnesses 1. Remove the two connector plates covering the large slot and hole as shown. 2. Find the Power Harness (05621139) and remove the nut. Slide one connector at a time through the nut. 3. Insert the two connectors from the power harness through hole in the motherboard entry bracket. 4. Once the harness is inserted into the hole, insert the nut over the connectors and secure the harness body to the motherboard entry tray.
6. Find the other internal harness (05621138) and remove the hardware mount kits and install onto the motherboard entry bracket from the back. 7. With all hardware removed, install the connector from the back of the motherboard entry bracket. Place one washer onto the standoff, insert through the hole of both the bracket and connector. Secure, with another washer, lock washer and nut. 8. Route harness between the upright frame and the rear frame.
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 1. Remove the upper mount shaft for ease of installing the Linear Knife. It will be reassembled a little later.
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. Extended Bracket 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.
7. Install the stacker mount shaft removed earlier through both holes of the knife mounting bracket. 8. Secure stacker mount shaft with existing ¼-20 x ½ Screw. 9. Reinstall the rear cover. Note: All but one cover mount screw will be re-used. The screw that sits behind the Linear Knife may be too hard to reach and thus will be left out.
Making Electrical Connections 1. Plug the D-Shell connector from the Linear Knife into mating receptacle on the printer. Tighten thumbs screws on connector. 2. Plug the round connector from the Linear Knife into the mating connector on the Printer. Screw the outer housing to secure the connector to the printer. 3. Plug power cord into the AC Entry. Do not plug into wall at this time. Connect any other cables that need to be connected to the printer.
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. 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.
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.
Installing the Stacker on the Linear Knife The stacker that was removed from the printer will be used on the accessory knife. 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.
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.
