2) The installed cartridge is unknown.
3) The possibility of ink-low error is displayed only by printer LED. (The information
is not displayed on the host computer.)
4) The print job cannot be canceled from the host computer when an error has occurred.
After the cause of the error is resolved, the printer can be recovered by pressing the
RESUME button on the printer's operation panel. The error can then be recovered on
the host computer, although the ongoing print job is deleted.
Plug and Play is not supported.
<Possibly occurring problems>
1) The host computer occasionally fails to recognize the infrared port of the printer in
4Mbps communication. "Hard power reset," i.e. disconnection of the printer from mains
power and removal of the battery, is required to recover from this condition. The
frequency of occurrence and the duplication are low. In case of frequent occurrence,
however, this problem can be avoided by lowering the communication speed.
2) If the cleaning operations, etc., start during printing, the error message "Write error"
may be displayed on the host computer. When the cleaning operations, etc. are
finished, the error message disappears, and printing operations continue.
3) If another operation is executed at the host computer (eg., launching another
application) while printing a large file (printing photo images from Photoshop etc.),
paper may automatically be ejected, or the printer may reset.
