Cleaning; Regular Maintenance - Sekonic SR-1800 Operating Manual

Cleaning

Make sure to turn the power off and remove the power plug from the outlet before
cleaning. Failure to do so may result in electric shock.
WARNING
External parts are made of plastic. Do not use benzene, paint thinner, or any other
volatile substances and chemical solvents. Doing so may result in discoloring or
deformation.
Caution
Regular Maintenance
When the rollers and reading sensors become dirty, various types of malfunction problems may
occur. Maintain the device regularly as discussed below. Maintenance frequency will depend on
usage (frequency of use, quality of sheet used, etc.) When you become aware of dirt or other
foreign objects, clean them off.
(1) Cleaning the device and its external parts
Wet a soft cloth with thinned neutral detergent, squeeze it hard and clean the device lightly
with it. At this time, prepare a dry cloth as well and wipe the device so as not to leave
moisture on it.
(2) Cleaning the rollers
· Clean the rollers according to the frequency of use and the stained conditions since stains
on them may be transferred to sheets and may cause a malfunction when sheets are fed
(once every a few days).
· Clean the rollers, in particular, after a large number of sheets or sheets fitted with copy
carbon are fed.
· Use antiseptic alcohol (ethanol) to clean the rollers.
· Use a soft cloth slightly wetted with antiseptic alcohol (ethanol) to lightly wipe off stains.
(3) Cleaning the Read Sensor
Since the read sensor is covered with optical lens, clean it with a soft cloth or cleaning paper
wetted with a small amount of antiseptic alcohol (ethanol) so as not to damage the glass.
CAUTION:
Handle the sensor with extreme care since the reading level will be degraded and a reading
error may occur if it is flawed.
(4) Maintaining the sheet feed path
Wipe off dirt such as bits of torn sheet with a soft cloth or cleaning paper wetted with a small
amount of antiseptic alcohol (ethanol).
