18 Printer Overview Design Your Own Mounting Design Your Own Mounting The illustration below gives an example of a printer-mounting shelf: Figure 3-9 • Printer Mounting Additional space is required for paper loading and service access. Consider mounting the printer on a movable platform so that the printer can be maintained outside the printer enclosure. Note • We recommend making the output slot 97 mm wide. This width should accommodate all paper widths that the KR203 printers can handle.
Printer Overview Printing Printing The printing sequence starts with the leading edge of the media resting at the cut position after loading media or printing a previous receipt. The printer begins printing the page upon completion of the transfer of the image to the printer. When the page has finished printing, the printer cuts the receipt to finish. The printer then presents the receipt to the kiosk client.
20 Printer Overview Printing Page Modes The printer sets the following modes using the Windows driver. Variable Page Mode The length of the page (receipt) varies with the contents. Pages shorter than the minimum page (receipt) length will be extended to the minimum length. Pages (receipts) longer than the maximum page (receipt) length will print the maximum page (receipt) length, then place the extra data on additional pages (receipts). Fixed Page Mode The length of the page (receipt) is fixed.
Printer Overview Buttons, Indicators and Sensors Buttons, Indicators and Sensors The KR203 printer uses controls, indicators, and sensors to enhance the usability of the printer for the client’s kiosk experience, the kiosk operator’s service and maintenance duties, and expand the developer’s ability to provide printing and service information to the host kiosk system.
22 Printer Overview Manual Printer Reset Sensing and Error Reporting The KR203 has sensing and error reporting capability available to the printer for internal process control, status reporting to the host and custom printer software development by the software integrator. Many of these features and functions are supported directly by the Windows Driver. See Table 7-1, Application LED States on page 67 for error codes.
4 Connections Cabling and Cable Routing Always use cable tie downs, use locking connectors where possible, allow for kiosk component servicing, and avoid electrical noise sources. • All cables that are near the printer, media path, or media should be tied to the kiosk chassis or printer mounting hardware. The operator can accidentally disconnect the printer or other kiosk components when maintaining the kiosk. Cabling must not interfere with the proper operation of the printer and media.
24 Connections Attaching Power Attaching Power The KR203 printer has unique power requirements to operate efficiently, safely and within safety and compliance regulation guidelines. To achieve optimum performance, an approved power supply should be used to operate the KR203 printer. Refer to "Printer Power Supply – 808099-004" on page 57. If a non-Zebra supplied power supply is used with the KR203, it must comply with the following requirements.
Connections Attaching Power DC Power Plug Requirement The KR203 printer uses a locking two pin connector. The mating connector is Tyco part number 1445022-2. The wiring for this connector and to meet the power requirements should be 20 AWG insulated wiring (UL type 1007). Tyco 1445022-2 Ground +24 VDC Figure 4-1 • Power Plug Caution • Never operate the printer and power supply in an area where they can get wet.
26 Connections Connecting the Printer to the Host Connecting the Printer to the Host Interface Cable Requirements Data cables must be of fully shielded construction and fitted with metal or metallized connector shells. Shielded cables and connectors are required to prevent radiation and reception of electrical noise. Additionally, the USB cable should include a ferrite located at the end of the cable closest to the host computer.
Connections Connecting the Printer to the Host To minimize electrical noise pickup in the cable: • Keep data cables as short as possible (6 foot [1.83 m] recommended). • Do not tightly bundle the data cables with power cords. • Do not tie the data cables to power wire conduits. • Avoid fluorescent lighting and power supply components. Communicating with the Printer The only way to begin using your complete kiosk printing solution is to utilize the Windows Driver.

5 Media Designing Your Own Media Dispensing System Properly dispensing the media to the printer is critical to the operation of the printer and quality print. The media, roll or fan-fold, needs to flow smooth and free with minimal drag or binding. Ideally it should have a clean and cool location for dispensing and storing media. Loading or dispensing media to the printer should not have interference or access restrictions with the kiosk enclosure or internal components.
30 Media Designing Your Own Media Dispensing System Designing a Roll Support The design elements needed for a good media roll support are: • Simple design with no loose parts that can get misplaced, installed incorrectly, or require special techniques that can, when done incorrectly or carelessly, have the operator drop the media in the kiosk. • Minimal drag. Do not use wires, cables or bars as a roll holder - all of these cause the roll to stop and start and rock back and forth.
Media Media Mounting Considerations Media Mounting Considerations The KR203 printer uses direct thermal media which is chemically treated to react to heat. The printer has several basic requirements for dispensing the media to the printer from a roll or fan-fold media which include: 10/26/2010 • Align Printer with Media - The center line of the media roll or fan-fold stack should align with the center of the printer to provide the best image quality and keep the media un-damaged.
32 Media Media Mounting Considerations Media Supply Method The KR203 printer supports two media supply types: outside wound roll mount; and stacked fan-fold media. The media printing surface faces up towards the ‘top’ of the printer and away from the body of the printer. Printing Surface Printing Surface Figure 5-1 • Media Supply Media Input Aperture The KR203 printer has a wide aperture to support a range of media mounting locations.
Media Media Mounting Considerations The direct media input (or angle of contact with media guides - not shown here) will change as the media is being consumed. Minimum Clearance Area for Printer Power and Cabling This area should have a continuous physical barrier separating the media and folds from binding in the cabling, printer body, kiosk chassis seams, etc. Figure 5-3 • Media Aperture 10/26/2010 KR203 Hardware Integrator Guide P1028247-001 Rev.
34 Media Media Guide Media Guide The media guide is a required accessory and must be installed for the printer to work properly. The media guide is available in four widths as shown below: Figure 5-4 • Media Guide Width (mm) Part Number Width (mm) Part Number 58 09170-058-3 80 09170-080-3 60 09170-060-3 82.5 09170-082-3 A printer demo kit (Part No.
Media Media Guide 3. Insert the media guide under the printhead. Insert the T-shaped tab of the media guide into the “T”-slot, slide it forward, and fasten the screw. Figure 5-5 • Media Guide Installation 4. Close the printhead. Media Guide Calibration When the media guide is changed, the printer will signal media present even when none is. You must instruct the printer to detect the sensor it should use again.
36 Media Determining Thermal Media Types Determining Thermal Media Types The KR203 printer uses direct thermal media. Direct thermal media has a chemically treated print surface that uses heat to expose or darken the area where heat is applied. Thermal transfer media or ordinary un-treated paper requires ribbon or ink for printing while direct thermal media does not. To determine what type of media is being used and print surface of the media, perform a media scratch test. 1.
Media Black Mark Media Requirements Black Mark Media Requirements The printer is optimized to detect black marks printed with IR sensitive ink and ignore preprint in IR blind ink. For 80 and 82.
38 Media Preparing a Media Roll for Use Preparing a Media Roll for Use 1. Turn the new media roll as shown below. Temperature-sensitive coating 1 Figure 5-6 • Paper Roll Orientation 2. Tear off a full turn of the media from the roll. Caution • This is important since the outer end of the paper is usually fixed to the roll with some type of glue or self-adhesive substance that might otherwise cause paper jam or even print head damage.
Media Preparing a Media Roll for Use 3. The loading process works best with the cut as a square, straight edge. Cut the paper in a suitable angle. If the media is not cut square and the operator does not have the ability to cut or tear a straight edge, then the printer can fail to load the media or even cause a media jam. The media should not make contact with the platen roller before the sensor detects the media.
40 Media Loading Media Loading Media Automated Media Loading The printer is designed to detect media when it is inserted into the empty media input slot at the rear of the printer. The printer begins turning the platen (drive) roller when the leading edge of the media passes over the media sensor. The printer will then feed, cut, and eject a blank receipt and then go to a ready state (solid green status indicator).
Media Loading Media Manual Media Loading Manual media loading is intended for maintenance operations, such as printhead cleaning and removing media jams. Please use the automated media loading procedure (page 40) to load media for normal operations. 1. Open the printhead. 2. Insert the media through the rear of the printer and under the open printhead. Pull the media just past the cutter and platen (drive) roller.
42 Media Clearing Paper Jams Clearing Paper Jams Should a paper jam occur, follow the procedure below: Clearing the printhead: Caution • The printhead becomes hot while printing. To protect from damaging the printhead and risk of personal injury, avoid touching the printhead. Caution • Always disable printer power by un-plugging the printer from the kiosk power supply or turning off the printer and/or kiosk power. 1. Carefully cut the media at the rear of the printer. 2.
