5 Quick Fixes for Most Zebra Thermal Printer Issues

Here are the top five methods that usually work for me when working on a variety of Zebra label printers – from the GK420 and GX420 series to the bigger 110xi and M4 printers.

Step 1: power reset

Switch the printer off using the switch at the back near the power socket. Give it two seconds, then switch it back on.

Step 2: reset to factory defaults

Hold down the single round button on the front panel. The indicator light will start a flash sequence: 1, 1-2, 1-2-3, and so on. When it flashes four times, release it. This resets the printer to factory defaults. See my other post for detailed information about factory resetting.

Step 3: Label width calibration

Hold down the button until the light flashes five times, then release it. This will make the printer enter label width calibration. It will print a series of widths, getting wider each time, on a label. When the printed width matches the label width (or your preferred setting), tap the button once to lock it in.

Step 4: All other calibrations

Hold down the button until it flashes twice, then release it. This will run an automatic set of calibrations

How to Clean Boot Symbol MC9090-G

41PpliNodjL._SY300_909XCLEANBOOT.zip

This file is intended for use when a CLEAN BOOT of an MC909X WM 5.0 device is required. Unzip the contents of this device to either the root of an SD Card (and place the SD Card in your device) OR the TEMP folder. Then follow the UPDATE LOADER boot instructions below.
909XCLEANBOOTANDBLANK.zip

This file is intended for use when both a blank Application Folder and a CLEAN BOOT of an MC909X WM 5.0 device is required. Unzip the contents of this device to either the root of an SD Card (and place the SD Card in your device) OR the TEMP folder. Then follow the UPDATE LOADER boot instructions below.

There are two methods to perform an Update Loader Boot on MC909X:

Method 1

  1. Navigate to the location where the ZIP file was unzipped
  2. Tap StartUpdLdr.exe
  3. After 20 seconds or so, the device will perform an Update Loader boot which will cause the PKGS.LST file deposited on the device to be processed. Leave the device on A/C power during the Update Loader process

Method 2

  1. Press the primary battery release on the mobile computer to partially eject the battery from the mobile computer.
  2. On an MC9090-G, while the battery is partially released, simultaneously press and release the trigger and the Power button.
  3. On an MC-909X-K or MC909X-S, while the battery is partially released, simultaneously press and release the left scan button and the Power button.
  4. Push the battery to fully re-insert it in the mobile computer. One audible click can be heard as the battery is fully inserted.
  5. The mobile computer initializes. During this time press and hold the trigger used on step #2 or step #3 (as appropriate) and place the device on A/C power either by placing it in a cradle or a CAM.
  6. The device will invoke an Update Loader boot, which will cause the PKGS.LST file deposited on the device to be processed. Leave the device on A/C power during the Update Loader process.

 

When the device has completed the process it will return to the Windows Mobile “”Tap the screen to set up your Windows Mobile-based device” screen. At this point, if you used an SD card, please remove it from the device. If you placed the files in the TEMP folder, they will be automatically erased by the CLEAN BOOT process.

Samsung Galaxy S3 for $99?

Seems that AliExpress is having a Samsung Galaxy S3 for $99 go up for sale (only 5) in about 11.5 hours. Not sure I can trust this, but for $150 (with shipping) I can at least replace the broken screen on the current Galaxy S3 I have that just broke today.

Lenovo Yoga 13 Fan Noise

[stextbox id=info]Update:

This is an update from “Bloo” on the Lenovo forum thread surrounding this issue.

tl;dr

I’ve approved an update that contains a new thermal map that spins the fans up later and to a lower RPM.  We plan to release an update to apply this new thermal map, along with a package that will restore the old thermal map in case anyone wants to backlevel.

[/stextbox]

I just purchased (11/19/12) the new Lenovo IdeaPad Yoga 13 from Best Buy and upon unboxing and turning on for the first time, I noticed the fan constantly runs. It’s rather annoying! Some research led me to the Lenovo support forums where there are plenty of others complaining about this. I’m going to dig into the problem a little more intimately soon I hope to see if it’s a power management issue or if there are some fan speed control settings hidden somwhere. There are 3rd party applications I’m aware of but I want a response from Lenovo on this. I’m contemplating returning this — it’s that annoying.

It seems (last updated today) that one consumer returned their purchased unit to Best Buy from a different city and the new system does not exhibit the fan noise issue. I am awaiting response as to which model he/she picked up as a replacement.
