INK REFILL
If logo becomes faint, refill it with logo ink following the procedure given below.
Ink inlet
1. Remove the printer cover.
2. Take out the logo in the direction of the arrow. (Fig. 1)
3. Pour two or three drops of ink through the ink inlet provided on the logo back.
(Fig. 2)
4. Mount the logo in the reverse order of taking out.
5. Replace the printer cover.
Precautions
1. The logo ink first gives a clear print 10 to 15 hours after being poured into the logo.
Therefore, refilling after the daily business is most effective.
2. Overinking should be avoided. This will create a blurry print.
3. The ink is exclusively used for the logo.
Do not apply the ink to the ink ribbon and ink roller.
* When the supplied ink is exhausted, purchase the logo ink specified by SHARP.
