Question about Zebra Z4Mplus Label Printer

1 Answer

White lines on labels.

I'm getting white lines on the front end of each printed label and I'm wondering if the printhead is going bad. I can crank up the heat settings and it helps for awhile but then it starts again. Any ideas? Can the printhead be changed easily or does a technician have to be used?

    Looks like I can get a 300dpi printhead at several locations online for around $500. Hopefully it will be easy to replace.

The thermal printheads can be replaced, all that is needed should be a Screwdriver. the problem that you will most likely have is finding a source for the replacement part

Gaps in barcode with Zebra S4M


The gaps run in the direction of the label feed? You have a bad printhead. Bad dots on the printhead prevent it from printing your format in the areas that you see the blank lines.
There is no easy fix other than replacing the printhead. You can prevent (or actually prolong the time between failures) in the future by periodically cleaning your printhead. It's recommended that you clean the printhead after every roll of labels. The printhead is underneath the hinged assembly. Over time, ribbon or adhesive from the labels builds up and causes dots to go bad - creating the blank lines you see. Clean your new printhead with rubbing alcohol.

Tip

Avoid buying a new thermal print head!!


Thermal printheads - white lines - - move your image!

Hi People,

I've been a printer engineer for many years now, before that i worked designing label formats and operating thermal transfer printers that produced over 2,500,000 labels daily. During my time operating thermal transfer printers I discovered that sometimes you can have a printhead that blows 1 pixel out, and no more will blow for 3 - 6 months! As sod's - law would have it, the blown pixel would be through a barcode or image, making the printer unuseable until the expensive (usually 300.00 - 1500.00 pounds) printhead has been changed. If you have many vertical white lines through your labels or tags, this might not work. Most makes of Thermal printers that have an LCD display will have margin settings and/ or image movement settings that you can change through the operator panel, you will have to consult your user manual. Simply move the image across the page until the white line caused by the blown printhead is in an unprinted area or sufficiently hidden between characters! In addition to this, if you are using software such as bartender, label matrix or similar, you should be able to edit the label image or label format on your Pc, and manipulate your label format in a matter of seconds, again moving or changing your data fields in a way that hides the offending white line between characters or in an unprinted area. I know this will not always work, but its worth a go as you could extend the life of your print head by upto 6 months.

Zebra lp 2824 faded printing


Many factors affect print quality: Heat settings, speed setting and label face stock quality and type are a great place to start. How old is your printer? How many labels have been printed through it (there is an odometer that tells your this on the config label). Is the printhead dirty? Use > 90% isopropyl alcohol on a cotton ball or microfiber cloth to gently clean the printhead.
I would start by checking the heat and speed settings in the driver - crank up the darkness and crank down the speed a notch or two at a time until you get the print quality that you are looking for. If all of this fails, you may need a new printhead (not too easy to replace on this model). Printheads are made up of an array of resistors. These can loose their electrical resistance over time and require more energy (controlled by the darkness setting) to get the same results as a new printer. Printheads, like labels and car tires are considered a consumable commodity.

All of the sudden my bar codes are not fully printing. Missing some lines on the bottom. Also the numbers are not printing rel clear. Have ran this label before and no problem. Now it is all bar codes.


Try cleaning the printhead, then print the zebra test print. (see user manual) or just print a solid black box 4" wide by 1" long. If you have white vertical lines through it you may need a new printhead.

If print test is good try increasing the heat/darkness setting

LP2844 Printing light


Click start on your computer, go to control panel-printers and faxes folder. Highlight your Zebra printer and select 'printing preferences'. You are looking for a place to turn up the heat settings "Head Settings" or "Heat Settings". These get reset down to the lowest setting when you continually open the cover without turning the printer off first....exposing the printhead to light.

White vertical line runs through a shipping label


The problem is that the printhead is damaged and will have to be replaced. Assuming there are no other letters in the TLP2844 model number you gave then the part number for the printhead is G105910-053 and will cost around $100. Hope that helps.

Zebra 140Xill problem


Whenever you open the printhead, the Pause led will light.

If you hit the Pause button, the printer should go back on-line and resume printing (if you didn't turn it off).

If that doesn't work, try the calibration button (labels will feed out), then the Pause button, then the Feed button.

If you don't want to toss too many labels when you calibrate, the "maximum label length" (or some name like that) can be adjusted through the front panel.
