Zebra Label Printing Solution

The printer is just one of three parts of a printing solution. To print; you need a printer (ZD621 or ZD421), compatible media (thermal transfer ribbon cartridge or rolls, and thermal transfer media; or just direct thermal media), and software (driver, applications or programming) to tell the printer what to do and print. The printer can print without being connected to other devices or systems.

The media may be labels, tags, tickets, receipt paper, fan-fold stacks, tamper proof labels, etc.

Zebra assists you with label design and print with the free label and form design software: ZebraDesigner ™ for Windows PC operating systems.

Zebra provides a complete suite of free Link-OS software applications and drivers to configure printer settings, print labels and receipts, get printer status, import graphics and fonts, send programming commands, update firmware, and download files.

The Zebra web site or your reseller will be able to help you identify media for your desired use case.

Modes of Printing

You can operate this printer in many different modes and media configurations:

• Direct thermal printing: uses heat sensitive media to print.

Introduction

• Thermal transfer printing: uses thermal transfer ribbon cartridge or ribbon rolls, where heat and pressure transfers ink from the ribbon to media.

• Standard Tear-Off mode: allows you to tear off each label/receipt or batch print a strip of labels and tear them off after it is printed.

• Label Dispense Mode: if an optional dispenser is installed, the backing material can be peeled away from the label as it is printed. After this label is removed, the next one is printed.

• Media Cutting: if an optional media cutter is installed, the printer can cut the label liner between labels, receipt paper or tag stock.

• Linerless media printing with Cut or Tear-Off label options: allows for easy pick and place label applications.

• Stand-alone: the printer can print without being directly connected to a computer.

• A printer with the color touch display option can use menus to access and print a label

format/form.

• A Link-OS App connecting via Bluetooth (Wireless option).

• An auto running label format/form (programming based).

• A data input device connected to the printer’s USB Host port or serial port. This mode

accommodates data input devices, such as scanners, weigh scales, a Zebra Keyboard Display Unit (ZKDU), etc.

• Shared network printing: printers configured with Ethernet (LAN) and Wi-Fi interface options include an internal print server.

Controls and Indicators

This section discusses the two user control panel variations and their functionality.

User Interface

The primary user controls are found on the front of the printer. The ZD-Series Desktop printers support two user interface options.

• Standard User Interface — This interface provides basic control and status needed by an operator. Printer operating status is reported by five (5) icon indicator lights. The icons represent several functional areas of operation. The indicator lights, as a group, provide a wide range of printer status notifications when used in combination. They are visible from a greater distance than you can read on a printer with a display. Go to Meaning of the Indicator Light Patterns on page 41.

• This interface supports operator tasks of replacing printing supplies (labels, receipt paper,

transfer ribbon, etc.) when prompted by two indicators.

• Status indicator’s icons represent a functional area of printer operation.

• Status indicator lights typically use color to show the operator the functional status of the printer.

The status indicator lights may be off (not lit), red, green, or amber (orange/yellow). Red is ‘needs attention’ or ‘not ready’. Green is for ‘ready’ or ‘functioning’. Amber (orange/yellow) is for busy or active process (data downloading, over-temperature cooling cycle, etc.). An off or un-lit status indicator does not require the operators attention.

• A status indicator can flash (blink), fade (bright to off), alternate between colors, or remain on in a

variety of patterns that denote various printer activities, and operational status as a group.

• Control buttons are used in various combinations to access internal utilities that calibrate the

printer to your media and make limited print settings.

• Color Touch Display and Interface — The Color Touch Display interface provides easy access to printer setup, configuration, and is customizable for all user types. The interface includes all the Standard User Interface controls and indicators to provide you with common functionality and behaviors for these Link-OS printer models.

• The display option provides written printer status and messages.

• The display supports 19 languages, selectable by the operator, or with programming.

• It has a menu system. Users can make changes to print settings (darkness, speed, etc.), run

utilities, and set wired and wireless communication interfaces (Serial, Ethernet, Wi-Fi, etc.) that are installed on your printer.

Media Roll Core Size Adapters

Adapter Kits

The media roll adapters kit includes three pairs of media roll adapters. The kits are for the following inner

diameter (I.D.) media cores

• 38.1 mm (1.5 in.)

• 50.8 mm (2.0 in.)

• 76.2 mm (3.0 in.)

Adapter Usage

• The adapters are intended to be permanently installed in the printer.

• They may be changed to support other media roll sizes that require one of these adapter sizes.

• The adapters may wear out if they are changed too much.

• Removing the media adapters to print on standard roll cores may leave plastic pieces in the media

roll holders side areas that rub against the roll. Push those attached pieces back into the side of the media roll holder.

Installing Media Roll Adapters

1. Place one screw in the top adapter mounting hole of both of the roll holders. Start turning the screws

clockwise using the T10 wrench until the tip of the screw is just protruding through the inside of the roll holder. The screws are self-tapping.

2. Place the adapter on the inside of the roll holder. The large side of the adapter is on top. The smooth

side (no ribs) faces the middle of the printer.

3. Align the adapter’s top screw hole to the protruding screw tip and pinch it tightly to the roll holder body.

Tighten the screw until there is no gap between the adapter and roll holder. Do not tighten beyond this point. Over tightening will strip the thread.

4. Insert a screw in the bottom adapter mounting hole. Pinch the adapter tightly to the roll holder while

tightening the screw. Tighten the screw until there is no gap between the adapter and roll holder. Do not tighten beyond this point. Over tightening will strip the thread.

Print Resolution Upgrade Kits

There are four (4) print resolution upgrade kits. The same procedure is used to change all the printhead resolution upgrade kits. Both the printhead and platen (drive) rollers must be changed and are resolution dependent. The printer automatically detects the change in printheads and the platen roller materials are identified by color.

Standard Printing

• Change the printer from 203 dpi to 300 dpi printing.

• Change the printer from 300 dpi to 203 dpi printing.

Linerless Printing (for Direct Thermal ZD621 printers only)

• Change the printer from 203 dpi to 300 dpi printing.

• Change the printer from 300 dpi to 203 dpi printing.

Printheads used in the upgrade kits include a 203 or 300 marking to help you keep the unpackaged upgrade printhead separate from the original printhead. The original printhead contains no marking identifying its print resolution.

The platen (drive) rollers are colored differently to help you keep from accidentally using the old platen roller. Go to Identifying Platen Drive Rollers Types on page 32.

Installing the Printhead Resolution Upgrade Kits

1. Turn the printer off and disconnect the power.

2. Use the platen roller replacement procedure. Go to Platen Cleaning and Replacement on page 255.

3. Use the printhead replacement procedure. Go to Replacing the Printhead on page 259.

4. Re-attach power and turn the printer on. The printer will automatically detect the change in printhead

(but not the platen) when the printer verifies the printer’s configuration.

IMPORTANT: For best results and the latest printer features and operation, download and install the latest printer firmware. Go to Updating Printer Firmware on page 273.
