Cleaning the Print Head


Cleaning the Print Head Automatically

If the ink on the page looks splotchy or smeared, or if blank spaces appear in
characters, the print head should be cleaned. To automatically clean the print head,

Cleaning the Ink Jet Nozzles and Contacts

If print quality does not improve after automatically cleaning the print head, the problem
may be dried ink on the nozzles, contacts, or on the print cartridge bracket contacts.
(1) Remove the ink-jet cartridge.
(2) With a clean, water-dampened cloth, gently wipe the entire copper colored area,
including the nozzles and contacts.
To dissolve any dried ink, hold the damp cloth against the nozzles for a few seconds;
then gently blot and wipe dry.
(3) Allow the copper-colored area to dry, and re-install the cartridge.
(4) Press RETURN, and then CODE + SHIFT + INK CHG, and close the cover.
If the machine still fails to print properly, clean the bracket contacts in the carriage.
The bottom of the ink jet cartridge is covered with wet ink.
Avoid contact of ink with skin and clothing. Ink may cause irritation -
especially to the eyes.

    ​I have a brother dp 540cj and it has a built in diskette drive.
    I have a ibm thinkpad latop. I connected a Memorex external usb floppy drive to the ibm thinkpad laptop. i'm copying 3 files from the ibm thinkpap (notepad) to the square 1.44 mb diskette. no problem, the 3 files were copied to the diskette.
    ​I turn on the brother dp 540cj, select file manager, insert the square diskette. the brother dp 540cj open only the file names on the disk. I try to open word text on either of the 3 files on the disk and the brother dp 540cj don't open the word text in any of the 3 files. I have been trying for several days to open the word text on the files using the brother dp 540cj and don't have any further instructio​ns for this problem. I tried saving the file names to all coding - Unicode, ansi utf-8 and can't fix the electronic problem.
