This chapter describes how to perform routine maintenance.
To ensure the continuous high quality operation of your B-492L/R, you
should perform a regular maintenance routine. For high throughput it
should be done on a daily basis. For low throughput it should be done on
a weekly basis.
To maintain the printer performance and print quality, please clean the
printer regularly, or whenever the media or ribbon is replaced.
1. Turn the power off.
2. Open the top cover.
3. Turn the head lever and pinch roller lever to position
@, then open the
ribbon shaft holder plate.
4. Remove the ribbon and media.
5. Clean the element of the print head with the print head cleaner or a
soft cloth slightly moistened with ethyl alcohol or isopropyl alcohol.
WARNING!
1. Be sure to turn OFF the
power of the power supply
unit before performing
maintenance. Failure to do
this may cause an electric
shock.
2. To avoid injury, be careful
not to pinch your fingers
while opening or closing the
cover and print head block.
3. Be careful when handling
the print head as it
becomes very hot
immediately after printing.
Allow it to cool before
performing any
maintenance.
4. Do not pour water directly
onto the printer.
CAUTION!
1. Do not allow any hard
objects to touch the print
head or platen, as this may
cause damage to them.
2. Do not use any volatile
solvents including thinner
and benzene, as this may
cause discoloration of the
cover, print failure, or
breakdown of the printer.
3. Do not touch the print head
