Power Requirements
The SureMark printers do not contain a power supply. When the printer is operating
in RS-232 mode, an external power supply must be attached to connector J2 of the
interface card of the printer. This connector is located under the printer and is
accessible without removing the printer covers. (See Figure 4 on page 12 for
thermal/impact SureMark printers, and Figure 5 on page 13 for single-station
SureMark printers.) Connector J2 has the following pin functions:
Pin Signal
1 +24Vdc
2 Not Connected
3 Ground
When the SureMark printer is operating in RS-485 mode, power is supplied to the
printer from the IBM POS system. The system supplies 5V, 24 V, or 38 V dc to the
printer.
When the SureMark printer has the USB feature installed and is using the powered
USB cable, 24V is supplied from the system unit.
When the SureMark printer has the USB feature installed and is using a 4-wire
cable with a Type B connector, you must use an external power brick (+24V dc).

v IBM 4694 systems (both SBCS and DBCS models)
