Zebra ZD620: Troubleshooting and Cleaning
Standard Interface Controls
1. Power Button — Turns power ON and OFF in the printer. It is also used to initiate low-power sleep
and wake states.
• Initial Power ON — Press the Power button until the printer’s indicator lights flash on. The
indicator lights will flash on and off in various combinations while the printer does self-diagnostics,
configuration checks, and integrate optional components which will take several seconds to
complete.
The Status indicator will turn solid GREEN indicating the printer is ready for normal print
operations.
• Sleep Mode — Pressing and releasing the button once will cause the printer to enter Sleep
Mode. The printer will turn off after storing various configuration and status information in memory.
All the indicators will be off except the Status Indicator will slowly change between On and Off to
indicate Sleep Mode.
• Power OFF with Sleep Mode Delayed — Press and Hold the button for 4-9 seconds. The
operator can start a batch print job and put the printer into the low power consumption state of Sleep
mode — after the job has finished.
• Power OFF / Shutdown — Press and Hold the button for 4-9 seconds. The printer will turn OFF.
• Power Failure Recovery Mode — This printer feature is activated by a hardware jumper setting
on one of the optional Printer Connectivity Modules installed in the printer. See Setting the Power
Failure Recovery Mode Jumper.
• The printer will automatically Power ON when plugged into an active (ON) AC power source.
• Supports Sleep Mode and Power OFF with Sleep mode Delayed.
• A Power OFF/Shutdown will reset the printer and then runs the Initial Power ON sequence.
Note • The Power Failure Recovery Mode is only available on printers with a Printer Connectivity Module
installed in the printer.
2. Status Indicator — Primary status indicator for overall printer health and operational status. This
indicator is also known as the Power indicator.
• Green: Ready for print and data activity.
• Green, Slowly Changing between ON and OFF: Printer is in Sleep Mode.
• Red: Media out, media detection error, head (cover/printhead) open, cut error, printhead
authentication failure.
• Amber: Printhead Over Temp (temperature), printhead element failure, out of memory while storing
content (formats, graphics, fonts, etc.), and interface power fault for USB Host or Serial ports.
• Blinking Amber: Printhead Under Temp (temperature)
• Blinking Red: Printhead Over Temp (temperature) — this status is coupled with blinking red Pause
indicator. Requires cooling and printer restart.
3. Pause Indicator — The printer is in Pause mode when the Pause indicator light is on. A label (print
form) or all labels (print forms) in the print buffer’s queue can be canceled when the Pause indicator is
on using the Cancel button.
• Amber: The printer is paused. Print, label FEED (advance), and other label routines are suspended
until the pause state is removed by pressing the Pause button.
• Blinking Red: Printhead Over Temp (temperature) — this status is coupled with blinking red Status
indicator. Requires cooling and printer restart.
4. Data Indicator — Indicates the status of data transfer activity.
• Off: Data is not being transferred.
• Green: A data communication operation has not finished but is not actively being transferred.
• Blinking Green: Data communications are in process.
• Blinking Amber: Out of memory while storing content (formats, graphics, fonts, etc.).
5. Supplies Indicator — Indicates media (label, receipt, tags, transfer ribbon, ribbon cartridge, etc.)
status.
• Red: There is a media out condition.
• Blinking Red: Ribbon Out.
• Blinking Red and Amber: Ribbon Cartridge Low (ZD420 Cartridge printers only).
• Blinking Amber: Ribbon In (ZD420 Cartridge printers only) detected while the printer is attempting
to print in direct thermal mode.
6. Network Indicator — Indicates network activity and status.
• Amber: 10 base Ethernet (LAN) connection detected.
• Green: 10/100 Ethernet (LAN) connection detected or when Wi-Fi (WLAN) has a strong signal and
is connected.
• Red: when an Ethernet (LAN) or Wi-Fi (WLAN) fault occurs.
• Blinking Red: during Wi-Fi (WLAN) association.
• Blinking Amber: during Wi-Fi (WLAN) authentication.
• Blinking Green: when Wi-Fi (WLAN) has completed but has a weak signal.
7. Cancel Button — Cancels print jobs.
• Only functional when the printer is in the Pause state.
• Pressing the Cancel button once causes the printer to cancel printing the next format in the print
buffer.
• Pressing and holding the button for two seconds cancels printing of ALL pending formats.
8. FEED (Advance) Button — Advance a label (print form/format).
• Feed One Label - Pressing (and releasing) the FEED button when the printer is not printing, causes
the printer to advance media one (1) blank form/format length (label, receipt, tag, ticket, etc.).
• Advance Multiple Labels - Pressing and Holding the FEED button when the printer is not printing,
causes the printer to advance labels until released. It finishes advancing to the beginning position of
the next label.
• Reprint Last Label (activated via a SGD command: ezpl.reprint_mode) - The intended purpose
of this feature is to allow reprint of a failed media print. If the printer runs out of media (paper, labels,
transfer ribbon, etc.), then the printer can re-print the last label (print form/format). The print buffers
that stores the print image available for reprint is cleared when the printer gets turned off or is reset.
9. Pause Button — Pauses print and media movement actions.
• Pressing the Pause button will stop print activities and place the printer into a ‘Pause’ state. The
printer will complete printing a label that is printing before it pauses.
• The Pause indicator will display Amber (orange/yellow) to indicate the Pause state.
• Pressing the Pause button while in Pause state will return the printer to normal operation. If printing
a multi label (form/format) job or another print job is waiting to print in the print queue, then the
printer will resume printing.
Open the Printer
To access the media compartment, pull the release latches towards you and lift the cover. Check the media compartment for loose or damaged components.
ESD Caution • The discharge of electrostatic energy that accumulates on the surface of the human body or other surfaces can damage or destroy the printhead and other electronic components used in this device. You must observe static-safe procedures when working with the printhead or the electronic components under the top cover.
Closing the printer
Lower the top cover. Press down in the middle of the cover in front until the cover snaps closed.
Zebra Printer Calibration:
The Zebra Printers (the ones that print tags and labels) will not calibrate utilizing the software drivers. This is a manual process, thankfully it is very simple, and does not appear to have to be done every time. Just at random intermittent intervals of the devices choosing.
For the immediate needs though follow the instructions below.
- Put your tags or labels into the machine.
- Press and hold the Pause button and the X button for a up to 5.8 seconds.
- The printer will perform a calibration tear off the excess and throw them out.
- After calibration the printer should look like the one in this printer. A solid green light on one side and a solid red light on the other.
If your printer is not printing a hang tag or label correctly check the movable sensor to make sure that it is middle as show below.
Restart Chrome
Still Not Printing
After trying recalibrating and ensuring the sensor is aligned in the center as shown it the picture on pg. 7 you will need to contact your Area Manager and they will need to restart your stratus core (Big Hammer). If the printers still do not print the Area Manager will instruct you on next steps
Cleaning ZD620
Your Zebra printer may require periodic maintenance to keep your printer functional and printing high
quality labels, receipts, tags, etc
Cleaning Supplies
The following printer cleaning supplies are recommended for use with your printer:
• 99% pure Isopropyl Alcohol wipes, (Never re-moisten cleaning materials used
to clean the printer).
• Fiber-free alcohol wipes for media path, guides, sensors and media path and interior.
• Can of Compressed Air.
Important •
The cutter mechanism does not require maintenance cleaning. DO NOT clean the blade or mechanism. The blade has a special coating to resist adhesives and wear.
Important •
Using too much alcohol can result in contamination of the electronic components requiring a much longer drying time before the printer will function properly.
Important •
Do Not Use an air compressor in place of the can of compressed air. Air compressors have micro contaminants and particles the get into the air system and damage your printer.
Eye Injury Caution •
Use eye protection to protect your eyes from flying particles and objects when using compressed air.
Recommended Cleaning Schedule
Interval: Clean the printer after every 5 rolls printed.
