We at PAXAR hope that you will come to appreciate the efforts and quality which have gone into producing your PAXAR 676 Printer and wish to remind you that you are our number one priority. We welcome any constructive comments or criticisms so that we may continue to offer you the best printer in the industry for years to come.
Warranty Information Limited Warranty PAXAR Systems Group, Division of PAXAR Corporation, extends the following warranties to the original purchaser of a PAXAR 676 which has been installed and operated using recommended procedures and operating conditions. Parts Parts found defective in material or workmanship will be replaced at no charge for a period of six months following the machine's shipment date.
Fabric Tapes, Card Stock, Heat Seal, and Pressure Sensitive rolled stocks. The printer interfaces to a computer or a main frame system that allows for computer input or even design of a label with PAXAR’S PCMate Plus's "FORMATTER" program. The printer can generate a complete label printed on two sides, with up to two colors on the top and a third on the bottom.
Support for blank or pre-printed fabrics, blank or pre-printed card stock and die cut blank or pre-printed pressure sensitive Interface PAXAR PCL via RS232 serial port - 9 pin D-shell Control Panel Push-button printer function with 2 Line x 24 Character International LCD Backlit Display Dimensions 17.0"...
This specification describes the hardware and application software requirements for the Personal Computer that is connected to the PAXAR 676 Printer. The PAXAR 676 Printer uses a DOS Version of PCMate or a Windows version of “PcMate Plus / Formatter ”. These applications create the tag or label formats (layouts) then fill and transfer data to the printer through the serial port of the computer.
30" deep to 32" high. Refer to Figure 2. Figure 2 - Recommended Workstation Layout. The location of the PAXAR 676 printer should be based on human factors. The printer should be located in an area that maintains optimum flow of your product while providing for the operator’s comfort.
AC Power Line PAXAR requires that the electric service be 10 Amps @ 115VAC or 10 Amps @ 230VAC. This will allow the computer and any additional support or service equipment to be plugged into the same service. Any electrical service which is supplying a PAXAR printer or peripheral equipment connected to a PAXAR printer should follow standard electrical code practices including proper grounding and neutral requirements.
Inspect the machine for shipping damage. If obvious damage is discovered, contact PAXAR for further instructions - in the U.S.A. at (570)-888-9116. In countries other than the U.S.A. please contact your local PAXAR supplier. Figure 3 Shipping Crate. Save the shipping materials to relocate the unit or return to factory for service.
Fuse Configuration The main fuse(s) on the Paxar 676 are located inside the AC power entry receptacle. The entry has a fuse drawer that holds the fuse(s) and selects the appropriate line voltage. If the number in the window DOES NOT match the AC line intended to be supplied to the printer, DO NOT plug the power cord in.
Installing the PC Interface Cable The 676 requires a 9-pin RS232 cable. This cable is provided with the printer. If the cable was not found it can be order from PAXAR (Part no. 351124). The male end of the cable should be connected to the 9-pin D-shell female connector that is located on the right side of the printer.
Printer Operation Loading Stock Figure 4 - Stock Threading LOADING STOCK FOR THE FIRST TIME 1) Adjust the unwind width wider than the roll of stock to be loaded. Set the stock roll on the unwind between the guides with the stock unwinding from the top clockwise.
Butt Splice NOTE: DO NOT RUN BUTT SPLICES THROUGH THE PRINT STATIONS The PAXAR 676 has been designed keeping the operators need to change supplies quickly and often in mind. Re-threading the stock is quicker than butt splicing. If however you have determined a butt splice is necessary, after loading a new roll of stock onto the unwind tape the free ends together.
Print Head Operation The print head modules are to be opened and closed for threading of stock and ink. The unit must also be opened to clean the head and for print head replacement. Later in the manual, under separate headings, cleaning and replacement will be covered.
NOTE: Make sure that the ink-ribbon take-up core and the ink-ribbon supply roll are both against the ink backer plate so that the ink ribbon tracks straight through the print station. Printer Operation • 19 Users Manual Model 676...

Adjustments Feed Roller Pressure General The rubber pressure roller is supported by an eccentric shaft mounted in bearings located in vertical slots in the front and rear mounting plates of the drive module. These bearings are supported by compression springs and controlled by cap screws located in the top of the bearing mounts.
A micro switch in the stacker rails allows the printer to detect a full load of labels in the stacker. The stack full condition will stop the machine when the stacker is full. Adjustments • 37 Users Manual Model 676...
Sensor Adjustments: All the micro switches and optical sensors in your 676 printer were calibrated at the time your printer was manufactured, however from time to time it may become necessary to readjust / recalibrate due to the large variety of stocks and inks that can be run on the machine.
Before making any adjustment to any of the three print station tangent points confirm the following: - Is the ink and stock loaded in the printer correctly? Adjustments • 39 Users Manual Model 676...
- Is the proper ink and stock loaded in the printer for the format downloaded? - Is the strobe setting(s) on the front panel set according to the ink and stock loaded in the printer? - Is the ink and stock of known types? - Are the correct width platen rollers installed in the print stations for the stock width loaded in the printer? To actually adjust the tangent continue as follows:...
The switch on the inboard stacker up right is used to stop the printer when the stack is full. A thumb screw adjustment is provided to set the stack height. Warning: some stock materials can not be stacked to the full height of the stacker because of excessive weight. Adjustments • 41 Users Manual Model 676...
Machine Set Up Sequence 1) Power off the printer, remove the media and ink and thoroughly clean it from the unwind to the stacker using alcohol and a clean soft cloth. The print heads should be cleaned as per the Print Head Cleaning instruction section in the manual. 2) Load a full roll of an average width media and ink on the printer.
- NEVER use anything metallic on or near the printhead. - Alcohol and a cotton swab are the recommended items to use when cleaning the printhead. RECOMMEND PAXAR "MASTER CLEANING KIT" # 921338 Procedure: -The Printhead should be cleaned every two to four hours of continuous usage. A good cleaning of the print head after eight to twelve hours of continuous usage should be done.
- Never use anything abrasive to the sensor and light bar. - NEVER use an alcohol based solution when cleaning the sensor or light bar. - Dry air or a cotton swab are the PAXAR recommended items to use when cleaning the sensor and light bar.
12) Replace the media and ink and double-check your work. Power the machine on and make sure that no adverse effects are noted. Maintenance • 45 Users Manual Model 676...

A) On the front panel arrow down to PRINT HEAD SETUP using the MODE button and press ENTER. B) Arrow down to HEAD CATEGORY for the print station you replaced the head in.
Lubrication Procedure General The 676 series printers are factory equipped with either composition bearings not requiring lubrication, pre-lubricated bronze bearings, or pre-lubricated needle bearings. The one exception is the rub cams on either end of the rotary knife. Periodic cleaning of the printer and removal of dust will greatly enhance the length of the time the printer will function.

676 as well. Matching stock and ink widths If your customer is running multiple media and multiple widths on their Paxar machine, Great! They are taking advantage of one the most compelling features of our printers: multimedia capability. Our printers can also reduce the width of the ink to only that area being printed.
Solution: Replace the printhead. Note current life counts on the printer. If less than 500,000 inches, return for a pro-rated credit. If problem continues: Check that the machine has all the static upgrades. Double check the connections and wires. Appendix E • 71 Users Manual Model 676...
Printhead Cleaning Procedure Printhead performance and life are influenced by proper handling and cleaning. • Dirt on the printhead which causes problems is often too small to see. • Exercise care in handling printheads as they are very susceptible to static.
