„ Instrument and printer (option)
• To clean the instrument, wipe it gently with a soft cloth moistened with water or mild
detergent. Never use solvents such as benzene, alcohol, acetone, ether, ketones,
thinners or gasoline, as they can deform and discolor the case.
• Wipe the LCD gently with a soft, dry cloth.
„ Printer head
The MR9000 Printer Unit (option) does not normally require maintenance.
However, depending on the conditions of use, the life of the head and platen roller
may be reduced due to paper dust and foreign matter adhering to them as the printer
is used for a long time.
In such a case, perform the following procedure to clean the head.
Cleaning
Do not directly touch the printer head because there is the risk of it
being damaged by static electricity.
Required items: Ethyl alcohol, cotton buds
Wear an anti-static wristband when performing this work to protect against
static electricity.
Use a cotton bud moistened
with ethyl alcohol to gently wipe
the heating elements on the
head surface. Press the OPEN button to
open the cover so that you can
see the head.
