5)-2 Cautions on cleaning the printer
Cleaning frequency
It is recommended that the case of this printer be cleaned approximately once a week. If the
case is left uncleaned for a long period, dirt deposited on its surface may become impossible
to remove.
Cleaning method
• To avoid electric shock, be sure to disconnect the power cord from the electrical outlet.
• Use a dry cloth to wipe away dirt. If the dirt proves difficult to remove, slightly moisten the
cloth with water or a mild detergent solution.
6) Notes on the PAPER OUT LED turning off when the paper FEED switch is pressed
When no paper is detected and the PAPER OUT LED turns on (or flashes), this is the time when
the first no paper event is detected by the following detectors.
• With print stop invalid, the paper end detector (PAPER OUT LED turns on and the printer
cannot go offline).
• With print stop valid the paper end detector (PAPER OUT LED turns on and ERROR LED
also turns on, and the printer goes offline).
When the PAPER OUT LED is lit, pressing the paper FEED switch causes PAPER OUT LED to
turn off, and the states of the LEDs on the control panel change as follows:
• If the print stop is invalid and the paper end detector detects no paper, only the POWER
LED turns on (same as the normal situation)
• If the print stop is valid and the paper end detector detects no paper, both the POWER LED
and ERROR LED turn on (same as the offline situation).
Therefore, in cases where the PAPER OUT LED turns off when the paper FEED switch is
pressed, be sure to fully understand the above situations.
The states of the LEDs on the control panel when no paper is detected are listed in the following
table.

7) Other
Because the printer is made of metal panel with plating, the surface may become rusty.
