Clean the printhead and paper—out sensor periodically to remove paper dust
and debris. Ata minimum, clean after every 100 rolls of use. Perform
these steps for cleaning:
1. Pull up the latch (14) and remove the paper roll.
2. Gently wipe the surface of the printhead and paper sensor with a cotton
swab soaked in isopropyl alcohol. When cleaning the printhead, touch
the printhead only with the cotton swab, not with your fingers.
Protect thermal paper printouts by following these guidelines:
e Do not apply tape or other adhesives over annotations or tracings on the
front side of the paper. Apply adhesives only to the back of the paper.
e — Store printouts only in paper folders. Do not store printouts in plastic
folders.
© Avoid extended exposure to sunlight, temperatures above 27° C (81° F),
or humidity above 70 percent.
The fuses are located in the rear panel of the instrument.
1. Place a thin, flat—blade screwdriver in the recessed area under the
retaining tab of the fuseholder. Twist the screwdriver to release the
retaining tab.
2. Pull the fuseholder out. Replace fuses with the same type, voltage
rating, and current rating. Refer to the parts list (pg. 5-9).
Many electronic semiconductor devices such as MOS ICs, FETs, optical
isolators,
or film resistors can be damaged by the discharge of static
electricity. It is very common for anyone to build up static charges,
especially when wearing synthetic clothes, and to transfer this charge to any
object touched. Such a discharge can damage or destroy Static Sensitive
Devices (SSDs). In most cases, the discharge is not even perceptible to the
person at fault.
In order to help prevent damage to SSDs due to static discharge, observe the
following precautions when performing any open-case test, maintenance, or
repair procedures:
