1 . When printing on a single cut sheet that is narrower than the carriage movement range, once the printer has been put in the cut sheet mode and the sheet of paper has been inserted, the following operations should be avoided: turning the power supply switch on or off, opening the cover, issuing the return home command (ESC), or sending a reset command through the interface.

When the carriage moves away from the home position, it may come in contact with the left end of the paper, causing a paper jam.

2.The cut sheet waiting state can be canceled by the DLE ENQ 3 command.

3.Use the ASB function to correctly determine the paper state. See Example Print Control for Cut Sheet later in this section.

Transmit Status Identification

The values of specific bits are fixed in the status information transmitted by the printer, so that the status bytes of commands can be identified. The user can therefore confirm the command to which the status belongs, as shown in the following table.

When using Auto Status Back (ASB), however, process the consecutive three-byte code (except for XOFF) as ASB data after confirming the first byte of the ASB. Otherwise, the status transmitted by using the command and the status of the second and following bytes of the ASB cannot be differentiated.
