Unit 3: Installation PRINTER INSTALLATION This chapter provides guidance on how to station, connect, and load the printer once unpacked. Following printer setup, proceded to the next chapter for information on interface selection. SITE LOCATION • Stationed away from hazardous materials. • Stationed within an enclosed structure that conforms to the printer’s enviromental requirements. • Stationed within operational distance of the host based on interface specifications.
Unit 3: Installation Figure 3-3, Printer Mounting Host Computer Breaker Box Applicator Power Cord OR Interface Cable EXT Interface Printer Interface Card Figure 3-4, Printer Connection ATTENTION: Figure 3-4 displays the printer interfaced with a host computer. However, the printer may also be interfaced with a PLC, keyboard, scanner, etc.
Unit 3: Installation MEDIA SELECTION The size and type of labels to be printed should have been taken into consideration before printer purchase. Ideally, the media width will be equal to, or just narrower than, the print head. Using media that does not cover the print head will allow the platen roller to tread upon its surface resulting in premature wear. The media edge will also wear a groove in the platen roller affecting print quality.
Unit 3: Installation MEDIA LOADING To load label media, unlatch the print head and remove any remnants that may exist of the prior media supply. Feed the free end of the media from the printer’s left side, beneath the shaft of the media guide, between the upper and lower halves of the label sensor, across the top of all forthcoming rollers, and through to protrude six or more inches beyond the printer chassis.
Unit 3: Installation OPERATIONAL MODE SELECTION There are two modes of printer operation: Dispense or Continuous. The difference between the two is the way that the label and paper backing is ejected. Before printer configuration, one must determine which mode will be used. This chapter identifies and defines the functional differences between the two.
Unit 3: Installation INTERFACE SELECTION This unit presents the printer interface types and their specifications. These specifications include detailed information to assist in the selection of the most appropriate method for the printer to interface with the host. The five acceptable interface methods are: • RS232C High-Speed Serial • IEEE1284 Parallel • Universal Serial Bus (USB) • Local Area network (LAN) Ethernet • 802.
Unit 3: Installation RS232C HIGH-SPEED SERIAL INTERFACE INTERFACE SPECIFICATIONS Asynchronous ASCII Half-duplex communication Bi-Directional Communication Data Transmission Rate 9600, 19200, 38400, 57600 bps Transmission Form Start, b1, b2, b3, b4, b5, b6, b7, b8, Stop (b8 will be omitted if using 7 bit oriented) Data Length 7 or 8 bit (selectable) Stop Bit 1 or 2 bit (selectable) Parity Bit ODD, EVEN, NONE (selectable) Codes Used ASC II Character Codes: 7 bits, Graphics: 8 bits Control Codes
Unit 3: Installation READY/BUSY INTERFACE SIGNALS PIN DIRECTION SIGNAL DEFINITION 1 Reference FG (Frame Ground) 2 To Host TD (Transmit Data) - Data from the printer to the host computer. Sends X-On/X-Off characters or status data (bi-directional protocols). 3 To Printer RD (Receive Data) - Data to the printer from the host computer. 4 To Host RTS (Request to Send) - Used with Ready/Busy flow control to indicate an error condition.
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 Figure 3-10, Socket Connection Diagram Lt408 Operator Manual 3-15 PN: 9001152A
Unit 3: Installation ALL INTERFACES RECEIVE 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. It acts much like a Print buffer to maximize the performance of the host and the printer.
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 CLEANING PROCEDURES Cleaning of the printer is a necessary maintenace activity to ensure print quality and longer printer life. There are two basic types of cleaning involved; the removal of loose debris and the removal of residue. Use a soft cloth and/or a pneumatic blower to remove debris from the printer. This process should be performed prior to the removal of residue.
Unit 6: Maintenance REPLACEMENT PROCEDURES This unit provides in-depth instruction on all primary component and assembly replacement, in addition to most secondary components. Use the text in conjunction with their accompanied graphics to ensure complete comprehension throughout the process. Especially observe all cautionary or warning notations. FUSE REPLACEMENT Fuse access may be gained externally without having to remove covers, etc.
Unit 6: Maintenance ROLLER REPLACEMENT The printer’s three rubber rollers are considered to be high-wear components due to constant treading of the print media and ribbon stock against their contact surfaces. This constant contact will eventually wear grooves into the rubber material and negatively effect print output. The procedure below applies for all three rubber rollers. However, some rollers do not incorporate the use of spacer (5) so in those cases, that process is to be ignored. 1.
Unit 6: Maintenance ADJUSTMENT PROCEDURES This unit 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 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.
Unit 6: Maintenance PRINT HEAD PRESSURE ADJUSTMENT Print head pressure adjustment allows for the print head to be adjusted to accommodate different media types (thicknesses). The pressure setting switch is two position (normal, high). The table that follows correlates the media used with a pressure setting. PRESSURE/BALANCE ADJUSTMENT Paper Width (inches) Dial Setting 2.17+ 0.612 to 2.16 2.56+ 0.62 to 2.55 1 2 3 4 PRESSURE REQUIREMENTS Paper Thickness (inches) 0.003 to 0.008 0.008 to 0.
Unit 6: Maintenance PRINT HEAD BALANCE ADJUSTMENT Print head balance is the equalization of pressure against the platen roller from one end to the opposite. If the print head balance is out of adjustment, the printed image will be darker on one side of the label than the other and the media will be prone to travel in the direction of least resistance. The adjustment of print head balance on the label can be subjective.
Unit 6: Maintenance RIBBON GUIDE ADJUSTMENT 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: ribbon spindle, ribbon roller, print head, or ribbon guide. The purpose of the adjustable ribbon guide is to compensate for the axis deviations of the other three.
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 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 DESCRIPTION/PROCEDURE VOLUME Adjusts the audible decimal level for error indication. Power on the printer, place on-line, and open the print head. When the beep is emitted, adjust the volume level accordingly.
