After the floppy disk drive of the embroidery machine is used for a period of time, the magnetic head will be stained with dirt. The reason is mostly due to the dust in the air and the worn magnets on the floppy disk sticking to the magnetic head; or the floppy disk used is of poor quality, damp, and moldy. All the reasons. When reading and writing information on the floppy disk, the dirty head will not only scratch the disk, but also cause read and write errors. Therefore, it is necessary to clean the head regularly. The following editor of computerized sequins quilting embroidery machine introduces several cleaning methods for the head of the floppy disk drive.
1. Drop 2-5 drops of cleaning liquid on both sides of the reading and writing holes of the cleaning disk. The amount of cleaning liquid should be moderate. Too little amount will not clean the dirt on the surface of the magnetic head; if the amount is too much, it will remain on the surface when cleaning the magnetic head. The cleaning fluid will affect the life of the magnetic head. Sometimes it will cause short circuit of electronic circuit and burn out components.
2. Insert the cleaning disk dripped with cleaning fluid into the disk drive according to the direction of the arrow on the label, and close the door of the floppy disk drive. For the 5.25 inch cleaning disk, when the drive door is closed, the cleaning disk will rotate and you can hear the cleaning disk and The contact friction sound of the magnetic head. When the drive door is closed, the 3.5-inch cleaning disk will not rotate. The 3.5-inch cleaning disk needs to be read and written to make the cleaning disk rotate. You can enter commands such as DIR to make the cleaning disk rotate (Note; at the DOS command prompt), and repeat the operation several times after an error message appears. This method is only suitable for newly purchased cleaning disks. The reason is that after the DIR command is entered, the system still controls the floppy drive head like a read-write disk. Go to the root directory to search. The root directory of the floppy disk is on side 0 of the disk. If you use the DIR command every time you clean the head, position the head at a fixed position. Then the position of the 0 track will inevitably be seriously polluted, which will not achieve the cleaning effect on the magnetic head, and also reduce the use efficiency of the cleaning disk. The head cleaning program provided by HD-COPY and DISKDUPE can be used. These cleaning procedures can make the cleaning of the magnetic head by the cleaning disk safer, faster, and cleaner through the rotation of the cleaning disk and the radial back and forth movement of the magnetic head. The cleaning time should not be too long, generally 10-35 seconds.

3. Take out the cleaning disk and write down the number of times the cleaning disk is used on the label of the cleaning disk. Do not use the cleaning disk more than 15 times. If the cleaning disk is soiled by head dirt (as can be seen from the color change of the cleaning disk gasket), a new cleaning disk should be replaced.
4. After cleaning, do not insert the floppy disk for operation immediately. It should be 10-15 minutes after the cleaning liquid on the head is completely volatilized before inserting the floppy disk for operation. Otherwise, the magnetic head will be adversely affected, the cleaning fluid will get on the floppy disk, and the data on the floppy disk will also be destroyed.
The above is the introduction by the editor of computerized sequins quilting embroidery machine: How to clean the floppy disk drive of the embroidery machine.
