TECHNICAL ISSUES

SERVICE PORT

Please note that this service port is designed for service operation only and is not for end users. A conversion cable (P/N: 21863157600) is required to connect this port to a RS-232 port to communicate with the host under protocol 9600 bps, none parity check, 8 data bits, 1 stop bit for that purpose.

Improper use of this port may jeopardize the printer!

DIP SWITCHES

A set of DIP switches can be found at bottom of MP-300 when the battery is removed as in below picture. Please note that these DIP switches are mainly designed for service operation only and is not for end users. For normal operation of MP-300, all switches must be set to “OFF”. Improper

settings of these

switchesmay jeopardize the printer!

The only adjustable switch for the user could be the switch position 1. When this switch is set to “OFF”, the printer prints under normal printing mode. When this switch is set to “ON”, the printer prints under high power printing mode with following cautions. The high power printing mode helps darken the low duty ratio graphs/logos. However, if the high power printing mode is applied on a high duty ration graph/logo, the battery life will be greatly reduced.

BAR CODE PRINTING

For adequate readability of printed bar code, it is advisable to set the bar code width to 3 (default value) or above.

For ladder type bar code printing, the bar code height is limited to 54

dots.

BATTERY POWER

The length of each service session of a fully recharged battery depends greatly on printer power loading and battery condition. For reference, an average brand new fully charged battery has been tested to support continuous printing under BlueTooth interface for about 7 and half hours with printed paper roll length of 420 meters.
