Chapter 5 Maintenance and Inspection
5.1 Maintenance
To maintain the equipment always in its best condition, it is important to perform maintenance checks and record the
results. Thus, potential problems can be detected early and trouble can be avoided.
5.1.1 Daily check
Without printer paper, you cannot obtain necessary information. Therefore, check the remaining quantity of printer
paper as follows:
(1) Open the paper cover on the front panel.
(2) Check the quantity of printer paper remaining. If red lines appear at the edges of the paper, replace it
with a new roll (the red lines indicate there is one meter or less remaining).
(3) If there is a sufficient quantity of paper, or after a new roll of paper has been set, close the paper storage
cover.
5.1.2 Periodic check
The self-diagnostic tests check the status of each function of the equipment on a per-block basis. Conduct periodic
checks as directed below.
(a) Operating procedure
