Unit 3: Installation IEEE1284 PARALLEL INTERFACE The parallel interface is a plug-in module that can be installed by the user and conforms to IEEE1284 specifications. It automatically detects the IEEE1284 signals and operates in the high speed mode. If the IEEE1284 signals are not detected, it will operate in the slower standard Centronics mode. For this reason, an interface cable and host interface conforming to the IEEE1284 specification must be present to fully utilize the speed capabilities.
Unit 3: Installation UNIVERSAL SERIAL BUS (USB) The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be installed by the user. It requires a driver (shipped with each printer that has the interface installed) that must be loaded onto the PC and configured to support USB peripherals using Windows 2000 or above. Details for loading the USB driver are contained in the USB Interface Manual that is shipped with each printer with a USB Optional interface installed.
Unit 3: Installation SOFTWARE SPECIFICATIONS Corresponding Protocol TCP/IP Network Layer ARP, RARP, IP, ICMP Session Layer TCP, UDP Application Layer LPD, FTP, TELNET, BOOTP, DHCP NOTE: Print data can be sent by LPR and FTP of TCP/IP and dedicated socket protocol. Printer status is obtainable by dedicated socket protocol. NOTE: In the TCP/IP protocol enviroment, LPD and FTP are provided for printing; TELNET for variable setup; ARP, RARP, and BOOTP/DHCP for address setup.
Unit 3: Installation DIPSWITCH SETTINGS The dipswitches serve to initialize the configuration saved on the Wireless-LAN board, print the configuration, and make a selfdiagnosis. To communicate with the host,set the communication mode by through switches 5 and 6, then set the remaining switches to the OFF position. Print of configuration and self-diagnsis are operable only on the screen after turning on the printer. Ensure all switches are in the OFF position when operating the printer.
Unit 3: Installation ALL INTERFACES This chapter contains information that is applicable to all interface types offered. Recieve Buffer The data stream is received from the host to the printer one job at a time. This allows the software program to maintain control of the job print queue so that it can move a high priority job in front of ones of lesser importance. A multiple job buffer allows the printer to continuously receive print jobs while compiling and printing other jobs at the same time.
Unit 3: Installation RECEIVE BUFFER CONTROL Causes For Receive Buffer Near Full Receive buffer near full occurs when the remaing free space of the buffer drops to 0.95MB of 2.95MB capacity or when the remaining free space is available for storing 50 of 500 items in the history buffer. Release Of Receive Buffer Near Full Receive buffer near full can be released when the remaining free space rises to 1.95MB or when the remaining free space is available for storing 200 items in the history buffer.

Unit 6: Maintenance Figure 6-1a, Print Head Replacement Figure 6-1b, Print Head Replacement LM408-412e Operator Manual 6-4 PN: 9001155A
Unit 6: Maintenance INTERFACE BOARD REPLACEMENT Circuit boards generally have long lives due to the lack of moving parts. Generally, if a circuit board becomes defective, it is contributable to a negative external condition. If it is determined that the circuit board has become defective, search the printer over for possible visual factors that may have led to the damage. 1. Switch off the printer and disconnect power supply cord. 2.
Unit 6: Maintenance FUSE REPLACEMENT The fuse is wired to the power receptacle and protects the printer from power surges from the electrical source. If a surge of electricity reaches the fuse, its filiment will melt creating a disruption of the flow. In order to bridge the gap so the printer may again be functional, the damaged fuse must be replaced. 1. Switch off the printer and disconnect power supply cord. 2. Unscrew fuse cap (1, Figure 6-3) from fuse cylinder (2) located on rear housing cover (3).
Unit 6: Maintenance ADJUSTMENT PROCEDURES This chapter covers all of the printer and printer accessory adjustments. These adjustments include mechanical adjustments required following the replacement of components and assemblies, in addition to, the operational adjustments required following a job change. PRINT HEAD BALANCE ADJUSTMENT Print head balance is the equalization of pressure against the platen roller from one end to the opposite.
Unit 6: Maintenance PRINT HEAD ALIGNMENT Print head position has a direct impact on print quality. The print head must be parallel with the platen roller for the printed image to be consistent across the label. 1 Open the right housing cover to access print assembly (1, Figure 6-5a). 2 Ensure print head (2) is latched (3). 3 Look downward to print head (2) to locate head alignment plate (4, Figure 6-5b). 4 Ensure the values of alignment scales (A) and (B) are the same.
Unit 6: Maintenance RIBBON GUIDE ALIGNMENT If the print ribbon is not spread smoothly over the print head when it makes contact with the media, print voids will occur at the point of the ribbon fold. Typically, this is the result of the axis of one of the following not being perfectly parallel with the platen roller: ribbon spindle, print head, or ribbon guide. The purpose of the adjustable ribbon guide is to compensate for the axis deviations of the other two.
Unit 6: Maintenance LABEL SENSOR POSITIONING The label sensor assembly provides a mounting apparatus for the eye-mark, gap, and paper-end sensors. Position adjustment of the label sensor is not required when using standard label media. When non-standard media is used, place a section of the media on the media ramp oriented as if loaded for printing. Manually grasp the sensor assembly and move it laterally so that the sensor indicators embossed in its side are aligned with the reference marks on the media.
Unit 6: Maintenance RIBBON SPINDLE TENSIONING The printer has two ribbon spindles; one to supply ribbon medium from the rear of the printer past the print head to the spindle closest to the front for the purposes of rewinding the used medium. The rewind spindle is coupled to the drive train and draws the ribbon medium forward incrementally with the print media (label/tag) comparable with gearing ratios. For a proper function, the spindles must be individually adjusted with the correct drag.
Unit 6: Maintenance OPERATIONAL ADJUSTMENTS These operational adjustments are for fine tuning the printer as necessary following the configuration process and are largely confined to the four potentiometers located on the operator panel. Refer to the table below for their function. POTENTIOMETER PITCH DESCRIPTION/PROCEDURE Is to be used in conjunction with the configuration adjustments. Make course adjustments there and then fine tune here.

Unit 7: Appendix GLOSSARY Bytes A collection of 8 bits used in the binary system. Capacity As it relates to RFID, the number of bits or bytes that can be programmed into a tag. This may represent the bits accessible to the user or the total number - including those reserved to the manufacturer (e.g., parity or control bits). Capture Window/Field Region of the scanner field in which an RFID tag will operate. Cavity A recessed area in something.
Unit 7: Appendix GLOSSARY Diode Allows current to flow in one direction but not the other to protect sensitive electronics. A diode functions by compositing two conductive materials with one possessing low resistance to electrical current on one side and high resistance on the other. Dipswitch Complex A group of tiny switches directly attached to a circuit board to enable configuration for a particular type of application. These switches are two-position: On/Off.
Unit 7: Appendix GLOSSARY Factory Programming Relative to RFID, the programming of information into a tag occurring as part of the manufacturing process resulting in a read-only tag. Field Programming In RFID, programming that usually occurs before the tag is installed on the object to be identified enabling the introduction of data relevant to the specifics of the application. However, the tag would typically have to be removed from its object.
Unit 7: Appendix GLOSSARY Key The button on a panel that may be pressed to send an electrical signal to influence a predetermined activity. Keyed A physical object shaped in a manner so as to prevent unwanted movement or to ensure desired movement. Kg (Kilogram) A unit of weight measure within the metric system. Kilo-Bytes Used to describe data transfer rates or storage capacity of approximately 1000 bytes.
Unit 7: Appendix GLOSSARY Modulation In RFID, the methods of altering carriers in order to transmit the encoded information. Nest A set of similarly shaped objects with one smaller and resting within the other. Nominal The point between a positive and negative deviation which is considered to be optimum. Nut A small metal block with a threaded hole through its center for screwing onto a bolt.
Unit 7: Appendix GLOSSARY Print Head The device on a direct thermal or thermal transfer printer containing the heating elements that causes an image to be transferred to print media. Processor A programmable device that performs all the instruction, logic, and mathematical processing in a computer - is the brains of the computer. The processor is a microchip that is installed on a motherboard (primary board) that coordinates hardware components. Also referred to as “CPU”.
Unit 7: Appendix GLOSSARY A system of finding the position or location of assets. RFID Tags A microchip attached to an antenna that is packaged in a way that it can be applied to an object. The tag picks up signals from, and sends signals to, a reader. The tag contains a unique serial number, but may have other information and come in many forms, such as smart labels that can have a barcode printed on it, or can simply be mounted inside a carton or embedded in plastic.
Unit 7: Appendix GLOSSARY Simultaneous To take place at the same time. Sleeve A thin hollow material that is inserted onto another to provide proportionate spacing. Snap Ring A circular clip that may be applied to a shaft, etc. to prevent another object from moving - used to retain objects in position. Solid An item that is not porous. An item that is not transparent or translucent. Spacer Any object of purpose to maintain a specific distance from two other objects - example: a sleeve or washer.
Unit 7: Appendix GLOSSARY Troubleshoot The act of locating the source of a problem or problems. Two-Dimensional Two of the projectories of an object: X axis is the distance left and right and the Y axis is the distance up and down. In a two-dimensional perspective, the Z axis is not recognized. Uniform The state of multiple objects being the same. Units Any fixed quantity, measure, etc.
