12. Inspection and Maintenance
12-1. Routine Inspection
Check the remaining amount of chart and recording condition on a daily basis to keep the unit in good condition. When
any abnormality is found, take an appropriate action according to the
“11. Troubleshooting”.
Maintenance/inspection item
Operation
Ribbon cassette
replacement
A ribbon cassette used for printing can last two to three months in
continuous use, depending on the operating condition.
When the print becomes less visible, replace the ribbon cassette with new one.
(See
“6-1.2. How to attach ribbon cassette”.)
Chart replacement
A chart paper can last about 20 days when fed at a speed of 20mm/H
continuously.
When the end of chart nears, an end mark (red line on the right edge of
chart) appears. In this case, replace the chart with new one.
(See
“6-1.1. How to set chart paper”.)
Cleaning
Wipe away dirt on the unit with a soft, dry cloth or a cloth dampened with
warm water or neutral detergent.
Do not use chemical solvents including thinner and benzine to prevent the unit surface
from melting. The chart guide is made of acrylic. It may produce a crack when a
chemical solvent is used.
12-2. Consumable Parts and Replacement Guideline
The unit includes some consumable parts. To use the unit for a long time in good condition, we recommend that these
parts be replaced regularly.
Do not replace parts other than chart and ribbon cassette by yourself. Not only does it fail to
replace properly, but it also may pose dangerous situation. Make sure to contact CHINO
’s
sales agent for replacement of consumable parts.
