 Paper saving functions

Memory switches MSW8-3 through MSW8-4 can be used to congure the settings

below, which save paper.

 Top margin suppression

The printer back feeds the paper before printing which reduces the blank space at the top edge of the paper.

The back feed amount can be specied.

 Line gap reduce

Automatically compresses the linefeed amount between lines. The compression

ratio can be specied.

CAUTION

Remove the partially cut paper before performing back feed for starting printing. The cut paper may be torn off in the next printing process, which may cause a problem.

 Auto side shift (MSW8-6)

This function dissipates heat load during frequent heat generation by a vertical

ruled line or other specic head heating element.

If no data is received within 15 seconds after each cut or print, the print position is

automatically slid N* dots to the right. The original print position is returned to at the

next slide timing.

* N is the MSW8-6 setting value.

CAUTION

 If the right margin is too narrow, this may result in some print characters being cut off.  This function is disabled under initial settings.  To enable this function, use MSW8-6 to specify an appropriate value for the maximum slide

amount.

Connecting the Interface Cable

1. Turn off the power.

2. Conrm the orientation of the interface cable and connect it to the port.

3. Insert the other connector rmly into the interface port of the host computer.

CAUTION

 When disconnecting the cable, always hold the connector.  Place the interface cable so that people do not trip on it.  Do not connect multiple interfaces at the same time.  Be careful not to insert the USB cable into the cash drawer kick-out connector.  To connect more than one printer to a single computer by USB, you must change the serial

number of the USB interface.

 There are models with a USB port on the interface board side.

With such a model, do not connect USB cables to both the printer main unit side and interface board side. If USB cables are connected to both, priority will be given to communication of the one connected to the port on the main unit side.

Pairing operation

You need to perform the operations below the rst time you establish a Bluetooth connection for Bluetooth data communication.

1. Detect Bluetooth devices

2. Congure pairing settings

——

1. Detecting Bluetooth devices

Conrm that Bluetooth is enabled on the host PC before searching for Bluetooth

devices.

This product will show up as "CT-S751_XX"(XX is last 2 digits of unique BD

address.) when it is detected.

Select this product from among the detected devices.

Note: You can search for devices and change the names.

When memory switch MSW13-5 is set to "No Response," nothing is displayed by

device detection.

You can temporarily switch this setting to device detection (detect mode) by opening

the paper cover and holding down the FEED button for two seconds. Detect mode

is exited when the connection between the host PC is terminated.

2. Conguring pairing settings

Normally, selecting the printer during device detection will transition directly to

pairing settings.

CAUTION

Some host PC congurations and models may not transition directly to pairing settings after the

printer is selected during device detection.

The operation required to congure pairing settings depends on whether SSP (secure

simple pairing) is enabled on the host PC. If SSP is enabled on the host PC, pairing can be achieved without additional operations. If SSP is disabled on the host PC, you will be prompted to input a passkey. Input the passkey as described below. Passkey Last four digits of the address on the self test printout (Letters A through F are uppercase) Example: If the address is 01:23:45:67:89:AB the passkey is 89AB. If you delete paring information from the host PC without deleting the corresponding pairing information on the printer, the printer may not show up if you detect devices again with the host PC. To delete printer pairing information, open the paper cover and then hold down the

FEED button for ve seconds.

Deleting pairing information on the printer will put the printer into discovery mode.

Auto reconnection

With iOS device Bluetooth communication, a connection between a paired iOS device and the printer is not automatically restored after it is lost. However, when auto reconnection is enabled, the printer tries to reconnect with an iOS device after two-way communication is enabled and automatically restores the connection.

——

CAUTION

This function is enabled when shipped from the factory. (MSW13-6) Auto reconnection can take some time to connect when the host is not an iOS device.

 Even if the partner device is an iOS device, the conditions below can interfere with the auto

reconnection function.

 When you want Bluetooth communication to cut off after printing is complete  When there are multiple iOS devices printing on the same printer

Under such conditions, disable auto reconnection.

Enabling and disabling auto reconnect

During self test, press the FEED button 3 times -> Auto reconnect = Valid During self test, press the FEED button 4 times -> Auto reconnect = Invalid At the end of self test, new setting will be printed as Auto reconnect [Valid] or [Invalid].

Refer to 4.3 Self Test
