3 Send the print job. The status light on top of the IR pod turns on. (Printing a complex document or using a software print spooler on your PC may delay the time it takes for the IR status light to turn on.) If the status light does not turn on, realign the port on your portable equipment with the pod, resend the print job and stay within the range of operation during printing.

4 If you have to move the device, for example, to add paper, make sure you stay within the range of operation to maintain the connection. If the connection is interrupted before your print job is complete, the IR port status light will turn off. You have from 3 to 40 seconds (depending on the host implementation) to correct the interruption and continue the job. In this case, the IR port status light turns back on.

5 The connection can be permanently broken (interrupted for more than 3 to 40 seconds) if the “sending” IR port is moved out of the range of operation or if anything passes between the two ports to block the transmission, such as a hand or piece of paper, or even direct sunlight. In this case, the job needs to be reprinted.
