Zebra Lp 2844-Z printer flashing green and red alternately?

I have a Zebra LP 284-Z label printer. The LED flashing green and red alternately. It means the FLASH memory is not programmed. It was working fine yesterday. I do not know how the memory got lost. I called
Zebra tech support. They told me they never see this kind problem. And He is doing research on it. It has no removable memory on the board. Everything is soldered on the board. Please help.

Thank you.

    The power to a 2844 was accidently removed due to a pure connection. When turned on only solid orange. We removed cover to check – now it flashes red and green. Could I be the same problem?

    Does not print my inventory labels, only a random series of letters and numbers on many labels.

-Install ZDownloader from Zebra's web.- visit this page and do nothing to use in step 3 part to download for your stable firmware, only find and download it
-Turn off printer and get ready on Zdownloader sofware-You could see easly "Auto Detect Printers" on ZDownloader, press and hold the label feed button and keep your finger in there then click the "Auto Detect Printers", if you are seeing your printer in list now, continue to keep your finger in feed button-Select the firware.prg file, right click with select your printer in list and click "Download to Selected." -you are still keeping your finger in feed button in this time. You will see the feeding will start and your problem fixed.
Sorry for my english, haven't got enough practice.

Sounds like it's in firmware download mode. Try sending firmware to it.

My zebra prints blanks. Tried resetting the mode. Turned it off. Held the feed button, turned it on, and when it flashed red I let off. It stays green and doesn't flash again. What am I doing wrong?

My work has the same label printer and when installed had the same problem. be sure that your settings are correct. underr the start buttton on the task bar click on "printer and faxes" find the "zebra 2844 " and right click on the bottom of this sub menu click on "properties" there should be two rows of tabs to choose from click on "printer settings" then select "printer default" on all available ie: fonts, spoolong format, line sub. click "apply" then "ok".

Try to calibrate the label length.
with the feed button pressed switch on the printer.
Keep the button pressed until you have Seven flash of the green led and release the button.
The printer will do a manul callibration.
After that when you press the feed button it should feed one label

I have Zebra LP 2844-Z printer and the barcodes

Here are 3 suggestions.

Check that your label size definition is correct, measure your label height in mm and check that your printer driver settings match.

Perform a calibration. How?? when printer is on labels loaded and green light, hold feed key and wait for 2 blinks then release feed key. (If you release it after 1 flash you will print a configuration label)

If you are using Zebra Designer, download latest version of Zdesigner V2. Install latest printer driver V2.63. This driver & Zdesigner allows you to calibrate the printer directly from within Zdesigner. Go to File/Printer settings/ advanced options and click calibrate at bottom of page. when printer calibrates then tick the box USE PRINTER SETTINGS and printer will now work properly.

Zebra LP 2844 is stalling out on every print.

Maybe the printer is not getting a good calibration on the label. If the status LED is a steady RED when trying to print, then the printer thinks its out of labels. A manual calibrationi could solve that.

1. Turn the printer off
2. press and hold down the FEED key while turning on the printer.
3. keep pressing the key until the status light flashes once, then let go
4. The printer will auto-calibrate for the size of label and then should be ready to use.

Press FEED once after its done and 1 label should feed.

Hope that helps !

Flashing red light

Hi Quadralady,
I found these possibilities listed in the manual:

1. Perform media length sensing.
2. Possible problem with label stock. Use only approved
labels and tags.
3. Possible label jam.
4. Insufficient memory for label size. Check the printer
memory configuration.
5. Possible software problem. Refer to the programming

Zebra LP 2824

the error you are getting is a label size error. a label variance of as little as 1/203th of an inch can cause this.

you need to recalibrate the printer to the media, hold feed when powering up the printer letting go once the light flashes 4 times. this will force the printer to autodetect the label size.

if you are specifying the label size in you software or driver settings, measure and double check the label size
