Toner Specks and Tiny Dots Appearing On Printed Pages

Specks depending on how and where they appear can sometimes look artistic, and can also be more of like annoying. If you’re familiar with pointillism, it’s a painting technique in which small dots of varying colors are applied in the canvass to form an art. Another example would be the fireworks, specks of lights glittering in the air creating an amazing illusion of flickering stars.

But what if you’re printing a very important document, say, a report for a business meeting. Then after getting the printed material from the output tray of your printer, you noticed some toner specks on the printout. Would you still consider it a form of art or you’ll just be frustrated?

Toner specks or tiny dots that appear on printed pages are problems that printer users may encounter when the imaging drum of their machine is damaged. To further explain, let’s use the MFC-7860DW printer model as our example. It is not actually the Brother TN450 toner (model of replacement use for the sample unit) that has the problem.

The primary root cause of this problem is the imaging drum unit or probably the fuser unit. Either of these components may result to unwanted spots on your prints once they’re damaged. So basically what you need to do to fix the problem is of course replace the obsolete component. The sample unit above uses a separate toner cartridge and drum unit, so it’s not necessary to replace both of them.

Another possible root cause could be the type of media used in the printing process. There are specific types of papers that is suitable for certain printer models and documents. Parchments and acetate papers can also be used on some laser type printers, but not all of those would give the same result. The setting of the printer before you hit the print button is one important factor when printing. Wrong configuration may lead to such problems, as well as using rough-surface media that are not compatible to your printer model.

If you have examined the imaging drum and found out that it isn’t damaged, and you used the right media, but still the damaged exist. Maybe cleaning the machine is the right solution, particularly the corona wire and fuser unit. We’ll not go into much detail on how to clean these two components. But we’ll try to make a follow up post for the steps on how to clean them. For now, see if you can find a tutorial on to perform fuser/corona wire cleaning.
