Introduction This section describes what you get in your shipping box and provides an overview of printer parts. This section also has procedures that describe how to open and close the printer and report any problems. Hello! ® Thank you for choosing a Zebra 2844-Z™ printer, a high-quality on-demand printer manufactured by the industry leader in quality, service, and value—Zebra Technologies Corporation.
Many illustrations in this manual show the TLP printer. While there are some physical differences between them, you can operate both printers using the same procedures. What’s in the Box? Save the carton and all packing materials in case you need to ship or store the printer later. After unpacking, make sure you have all parts. Follow the procedures for inspecting the printer to familiarize yourself with printer parts so you can follow the instructions in this book. 2 980410-001 Rev.
Inspecting the Printer Look at the outside of the printer and make sure that all parts are present. Opening the printer To access the media compartment, you must open the printer. Pull the release levers towards you and lift the cover. 980410-001 Rev.
INSPECTING THE PRINTER (continued) After opening the printer, check the media compartment. 4 980410-001 Rev.
Closing the printer For TLP printers, hold the top cover and press the “kick-stand” cover lock to release. MOVIE Lower the top cover. The ribbon carriage automatically folds up into place. Press down until the cover snaps closed. 980410-001 Rev.
Reporting Damage If you discover damage or missing parts: ■ Immediately notify and file a damage report with the shipping company. Zebra Technologies Corporation is not responsible for any damage incurred during shipment of the printer and will not cover the repair of this damage under its warranty policy. ■ Keep the carton and all packing material for inspection.
Getting Started This section describes how to set up your printer for the first time and use the most common operating procedures for loading media in tear-off mode and loading ribbon. Modes of Printing You can operate this printer in different modes: ■ Standard tear-off mode allows you to tear off each label (or a strip of labels) after it is printed. ■ In optional peel-off mode, the backing material is peeled away from the label as it is printed. After this label is removed, the next one is printed.
Attaching Power Supply Check the power supply to make certain it is appropriate for your input voltage. Warning: Use the Zebra-supplied power supply that came with your printer. Never operate the printer and power supply in an area where they can get wet. Serious personal injury could result! 1. Make sure the power switch is in the off position (down). 2. The DC power supply has a barrel connector on one end that must be inserted into the power supply receptacle on the back of the printer. 3.
Loading Roll Media When you load media, you must place the roll on the media hangers and then adjust the media guides. MOVIE You must use the correct media for the type of printing you require. When printing without a ribbon, you must use direct thermal media. When using ribbon, you must use thermal transfer media. The printer's ribbon sensor detects motion of the supply spindle.
Adjusting the Guides The adjustable guides direct the media toward the platen and print head. 1. Open the media guides by turning the guide adjuster knob to the rear. 2. Thread the media through the guides. 3. Close the media guides by turning the guide adjuster knob to the front. They should just touch, but not restrict, the edges of the media. 4. Unless you need to load ribbon, close the top cover.
Loading Ribbon MOVIE You must use thermal transfer media (accepts wax and/or resin transferred off a ribbon) when you use a ribbon in a TLP model printer. When loading ribbon, you install the supply and take-up rolls, then tighten the ribbon on the carriage. Install the Ribbon Supply Roll Before following these steps, prepare the ribbon by removing its wrapping and pulling its adhesive strip free. 1. Thread the ribbon through the carriage. 2. Press the right side onto the supply hub. 3.
Attach and Tighten the Ribbon You must align the ribbon so that it will be taken straight onto the core. 1. Attach the ribbon to the take up core. Use the adhesive strip on new rolls; otherwise, use tape. 2. Turn the ribbon take-up gear counter-clockwise (top moves toward rear) to remove slack from the ribbon. 3. Close the top cover. Remember that you need to release the cover lock, lower the top cover, and press down until the latches snap into place. 12 980410-001 Rev.
Auto Calibration NOTE: If you are using pre-printed labels, pre-printed label backing, or continuous media, see “Manual Calibration” on page 42. An auto calibration is performed when the printer is turned on (if media is loaded) or after a media error is cleared. When it is auto calibrating, the printer sets the sensor levels for, and determines the length of, the label you are using. If the status light flashes red, refer to “Manual Calibration” on page 42. 980410-001 Rev.
Operator Controls Power Switch Press up to turn ON or down to turn OFF the printer. CAUTION: The power should be turned off before connecting or disconnecting the communications and power cables. Feed Button Forces the printer to feed one blank label. Takes the printer out of a “pause” condition. (The printer is put into “pause” by either a ZPL II command or an error condition.) See “What the Status Light is Telling You” on page 37.
Printing a Test Printout Before you connect the printer to your computer, make sure that the printer is in proper working order. You can do this by printing a configuration printout. 1. Make sure the media is properly loaded and the top cover of the printer is closed. Then, turn the printer power on if you have not already done so. 2. When the status light is solid green, press and hold the feed button until the status light flashes once. 3. Release the feed button.
Hooking Up the Printer and Computer Your printer will have one of two combinations of interfaces: MOVIE ■ Universal Serial Bus (USB), parallel and serial ■ USB, ethernet (using the Internal ZebraNet® PrintServer II™) and serial Each specific interface option—USB, parallel, ethernet, serial—is discussed individually. You must supply the required interface cable for your application. CAUTIONS:Keep the power switch in the OFF position when attaching the interface cable.
USB Interface Requirements Universal Serial Bus (version 1.1) provides a high-speed interface that is compatible with your existing PC hardware. USB’s “plug and play” design makes installation easy. Multiple printers can share a single USB port/hub. Parallel Interface Requirements The required cable (IEEE 1284-compliant is recommended) must have a standard 36-pin parallel connector on one end, which is plugged into the parallel port located on the back of the printer.
Communicating with the Printer Universal Serial Bus (USB) Communications The printer is a terminal device when using a universal serial bus interface. You can refer to the Universal Serial Bus Specification for details regarding this interface. Parallel Communications When using the parallel port, typically there is no setup is required once the cable is plugged in. If you should encounter any problems, consult the user’s guide that came with your computer.
Serial Communications (Continued) ^SC Command Use the Set Communications (^SC) command to change the communications settings on the printer. 1. With the host computer set at the same communications settings as the printer, send the ^SC command to change the printer to the desired settings. 2. Change the host computer settings to match the new printer settings. Refer to the ZPL II Programming Guide for more information about this command.
Adjusting the Print Width Print width must be calibrated when: ■ You are using the printer for the first time. ■ There is a change in the width of the media. Print width may be set by way of the five-flash sequence in “Feed Button Modes” (see page45) or refer to the Print Width (^PW) command (consult your ZPL II Programming Guide).
Operation & Options This section helps you get the most from your printer. You must use programming to control many of the printer’s functions. A few examples: ■ The ~JL command controls label length. ■ The ^XA^MTD^XZ command changes the printing mode to direct thermal; the ^XA^MTT^XZ command changes the printing mode to thermal transfer. ■ The ^XA^JUS^XZ command saves the new settings to flash memory.
Replacing Supplies If labels or ribbon run out while printing, leave the printer power on while reloading (data loss results if you turn off the printer). After you load a new label or ribbon roll, the printer flashes double-green until you press the Feed button to restart . Always use high quality, approved labels, tags and ribbons.
Printing in Peel-Mode ON OFF The optional dispenser allows you to print in “peel-mode” where the label backing follows a different path and the labels are presented one at a time for subsequent placement. Before using peel-mode, you must send the programming commands ^XA ^MMP ^XZ ^XA ^JUS ^XZ to the printer. Refer to your ZPL II Programmer’s Manual. 1. Remove several labels from the backing material. 2. Open the top cover. 3. Open the dispenser door. 4. Switch on the label-taken sensor. 5.
Printing on Fan-Fold Media Printing on fan-fold media requires you to set both the media hangers and the media guides in position. Lock-down Screw 1. Open the top cover. 2. With a sample of your media, adjust the media hangers to the width of the media. The hangers should just touch, but not restrict, the edges of the media. 3. Tighten the screw using a small Phillips driver #1. 4. With a sample of your media, adjust the guides to the width of the media.
Using the Cutter Option Printers that have a bezel with a motorized blade can dispense one or more forms that are then automatically cut from the media supply. This option cuts through continuous paper from rolls and liner between labels. Keep the cutter dry. Never use any solutions or solvents to clean the blade. Use the ^MM command to activate the cutter and the ^LL command to set the form length and gap distance. See the ZPL II programmer's manual.
Printing on Linerless Labels “Linerless labels” are a special label stock without a backing material or liner on the adhesive side. The media is wound upon itself with the adhesive on the back of the label in contact with the face of the label below. Direct-thermal LP printers can handle linerless labels when modified with a unique, non-stick platen coated with silicone.
Maintenance Cleaning When you clean the printer, use one or more of the following supplies that best suits your needs: DESCRIPTION Cleaning pens (12) Cleaning swabs (25) Cleaning cards, 4-in wide (25) Save-a-Print Head film, 4-in wide (3) The cleaning process takes just a couple of minutes using the steps outlined below. Printer Part Method Let the print head to cool for one minute, then use a new cleaning pen to swab the print elements (the thin gray line on the print head) from end to end.
Adhesives and coatings of media can over time transfer onto the printer components along the media path including the platen and print head. This build-up can accumulate dust and debris. Failure to clean the print head, media path and platen roller could result in inadvertent loss of labels, label jams and possible damage to the printer. Print Head Considerations MOVIE Always use a new cleaning pen on the print head (an old pen carries contaminants from its previous uses that may damage the print head).
Platen Considerations The standard platen (drive roller) normally does not require cleaning. Paper and liner dust can accumulate without effecting print operations. Contaminates on the platen roller can damage the print head or cause the media to slip when printing. Adhesive, dirt, general dust, oils and other contaminates should be cleaned immediately off the platen.
Replacing the Platen Removal MOVIE Open the printer and remove any media. 1. Using a pointed stylus (such as tweezers, small slot-head screwdriver, or razor-knife), unhook the tabs on the right and left sides. Then rotate them forward. 2. Lift the platen out of the printer’s bottom frame. Assembly Make sure the right bearing is on the shaft of the platen. 1. Align the platen with the gear to the left and lower it into the printer’s bottom frame. 2. Rotate the tabs back and snap them into place.
Replacing the Print Head In the event you need to replace the print head, read the procedure for your model of printer—either direct-thermal LP or thermal-transfer TLP—and review the removal and installation steps before actually replacing the print head. MOVIE Prepare your work area by protecting against static discharge. Your work area must be static-safe and include a properly grounded conductive cushioned mat to hold the printer and a conductive wrist strap for yourself.
Direct-Thermal LP Model Before following the steps in this procedure, open the printer by pulling the release latches forward then lifting the top cover. Removal 1. Use a #1 Phillips driver to loosen the four screws that hold the latch frame to the top case. MOVIE 2. Grasp the print head spring and pull it to the left; then, slide it free of the latch frame. 3. Gently pull the wire bundles from the print head. 4.
Replacing the LP Print Head (Continued) Assembly 1. Route the print head cables under the latch shaft and plug the print head cables into the receptacles on the print head. 2. Hold the print head against the bracket while replacing the screws and washers; attach the ground wire using the right screw and washer. Use a #1 Phillips driver to tighten the screws. 3. Slip the left end of the print head spring into the left side of the latch bracket; then slide the right end into the other side.
Thermal-Transfer TLP Model Before following the steps in this procedure, open the printer by pulling the release latches forward then lifting the top cover. Remove any ribbon from the carriage. MOVIE Removal 1. Grasp the print head spring and pull it to the left; then, slide it free of the carriage. 2. Use the spring to pry the print head clip off the right side of the carriage. 3. Pull the print head and bracket forward. 4. Use a #2 Phillips driver to remove the screw that holds the ground wire. 5.
Replacing the TLP Print Head (Continued) Assembly The new print head comes with the clip and ground screw attached. 1. Align the print head and bracket to plug the left and right connectors into the black and white wire bundles. 2. Attach the ground wire and secure it with the screw. Use a #2 Phillips driver to tighten it. 3. Insert the bracket pegs into the left side of the carriage. 4.

The printer is not receiving power.
3. The printer has failed its power on self test (POST). ■ If this error occurs right after you turn on the printer, contact an authorized reseller for assistance. There is a shortage of memory. ■ If this error occurs after you have been printing, turn the printer power off and on. Then, resume printing. 4. The printer is receiving data. ■ As soon as all of the data has been received, the status LED will turn green; then, the printer will automatically resume operation. 5.
7. The print head is under temperature. ■ Continue printing while the print head reaches the correct operating temperature. The print head is over temperature. ■ Printing will stop until the print head cools to an acceptable printing temperature. When it does, the printer will automatically resume operation. 8. FLASH memory is not programmed. ■ Return the printer to an authorized reseller. 980410-001 Rev.
Print Quality Problems No print on the label. ■ You must use the correct media for the method of printing you require. When printing without a ribbon, you must use direct thermal media. When using ribbon, you must use thermal transfer media. The printer's ribbon sensor detects motion of the supply spindle. ■ Is the media loaded correctly? Follow the instructions in “Loading the Media” on page 9. The printed image does not look right. ■ The print head is dirty.
The printing does not start at the top of the label, or misprinting of one to three labels. ■ The media may not be threaded under the media guides. Refer to “Loading the Media” on page 9. ■ The printer needs to be calibrated. Refer to “Auto Calibration” on page 13. ■ The correct media sensor may not be activated. Manual calibration selects the media sensing method for the labels being used (refer to the ^MN command in the ZPL II Programming Guide).
Manual Calibration Manual calibration is recommended whenever you are using pre-printed media or if the printer will not correctly auto calibrate. 1. Make sure media is loaded. 2. Turn on the printer power. 3. Press and hold the feed button until the green status LED flashes once, then twice. Release the feed button. 4. The printer will set the media sensor for the label backing being used.
Troubleshooting Tests Printing a Configuration Label To print out a listing of the printer’s current configuration, refer to the one-flash sequence in “Feed Button Modes” on page 45. Recalibration Recalibrate the printer if it starts to display unusual symptoms, such as skipping labels. See “Auto Calibration” on page 13. 980410-001 Rev.
Resetting the Factory Default Values Sometimes, resetting the printer to the factory defaults solves some of the problems. Follow the four-flash sequence instructions in “Feed Button Modes” on page 45. Communications Diagnostics If there is a problem transferring data between the computer and printer, try putting the printer in the communications diagnostics mode.
Feed Button Modes Power Off Mode (Communications Diagnostics Mode) With the printer power off, press and hold the feed button while you turn on the power. The printer prints out a listing of its current configuration. After printing the label, the printer will automatically enter a diagnostic mode in which the printer prints out a literal representation (see Figure 23) of all data subsequently received. To exit the diagnostic mode and resume printing, turn off and then turn on the printer.
