[Brother only]Ink blur does not improve even after cleaning.
Please try the following improvement methods.
Dirt may have accumulated inside the printer
If cleaning does not improve the ink stain, there is a possibility that dirt has accumulated inside the printer.I can think of it.If ink is accumulated at the position shown in the photo below, the ink lump will cause the print head.
It may get dirty and cause ink blurring.
Ink stains collect on the circled part of the photo.After cleaning this part with a cotton swab etc.
Re-cleaning may clean the printhead and allow ink to come out.
If the problem persists even after trying the above, there is a possibility that the ink cartridge is defective. Jit Customer Service Office (Tel::0120-41-1630 Please contact us from 9:00 to 17:00).
