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
Plotter pen and cartridge
pen replacement
When the trace printing (trend line) fade away or becomes less visible, replace
the cartridge pen with new one.
When the letters of digital printing fade away or become less visible, replace the
plotter pen with new one.
(See “6-1.2. How to set plotter pen and cartridge pen”.)
Chart replacement
A chart paper can last about a month when fed at a speed of 25mm/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.
Do not lubricate the mechanical section such as the main shaft and gear.
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 pens 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.
