Problems with image when printing onto laser labels.

replace the fuser unit

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

your problem is not good fusing. try with a different fuser.

BYPASS TRAY is sed when printing onto paper with a size not loaded into a paper tray or onto thick paper, overhead projector transparencies, postcards, envelopes or label sheets Can be loaded with up to 150 sheets of plain paper, 50 overhead projector transparencies, postcards, label sheets or sheets of thick paper, or 10 envelopes referred to as the "bypass tray" throughout the manual. (See page 2-60....ATTACHED )

These labels are supposed to be for laser or inkjet . A inkjet basically sprays the ink to print. A laser deposits plastic powder and then uses heat to melt it or fuse it to the paper. To get a good inkjet print you need a softwaer paper, to get a good laser print you want a harder paper and a glue that can handle the heat. I had a quick look at customer complaints on that product and you are not alone. Either the printing is coming off (inkjet) or the label is coming off inside the printer.

One of the other problems with labels in lasers can also be how the paper is printed. The paper can be rolled around a few rollers and drums. This action can be pretty close to how you peel the labels off of the backer sheet. Add a bit of heat to make the glue loosen up a bit and you get your problem.

Setting to thicker paper should have helped but the best thing you could do is print it flat. Most laser printers have a back tray that is usually closed. When opened the tray lets the paper come out without having to go around rollers. If your model doesn't do that about the only thing I could suggest is to try to print the labels on a cold printer. So that would mean one page or so at a time with a wait for it to cool down. You could also try a differant brand or another avery type but you may end up with a label collection if they prove to have the same problem with your printer.

The "ghost" image is "burned" onto the drum.

A laser printer is supposed to charge specific "dots" on the drum, and the toner-ink is supposed to stick only to those "dots", the paper is pressed against the drum, and then the "fuser" uses heat to "melt" the toner-ink onto the paper, to produce the printed page.

You need to replace the drum.

lsu stands for laser scanning unit. it tansfers the image onto the transfer drum, common problems are horizontal sync, i would suggest a replacement lsu

The drum is one of the most important major part of a laser printer. This part of the printer is so sensitive that fingerprints on it will ruin it and will cause poor print quality. If this is damaged then you will definitely need to have it replaced. This may cost a bit because it is a major component of a printer.

Laser printers works this way. A laser beam projects an image of the page to be printed onto an electrically charged rotating drum coated with selenium. Photoconductivity removes charge from the areas exposed to light. Dry ink (toner) particles are then electrostatically picked up by the drum's charged areas. The drum then prints the image onto paper by direct contact and heat, which fuses the ink to the paper.

I work in the comercial printing game, what your describing sounds like the surface finish used on these labels is only suited to black toner. Black requires the least amount of heat to set, where as colours require more radient heat the lighter the colour gets from black. Try printing a black/monotone lable and see if you still get this blistering problem.

Question, when the printer prints is there an image of the data on the ribbon when it spools onto the ribbon takeup spool? If so, the ribbon may be installed backwards. I'm sure you know what you are doing but one must check even the smallest detail when trying to solve these strange problems. If the ribbon is installed correctly and there is no image of the data on the ribbon you may be dealing with a bad printhead and the printhead needs to be replaced.
