Turn on the power to the printer, and press the FEED key on the operation panel. Feed the media and check that it stops at the position where one label has been peeled. CAUTION If the peeled label has not stopped at an appropriate position, due to differences in media types, media width, etc., adjust the MACHINE PEEL POSITION using the label printer utility extension function. Refer to 4.2 Obtaining the LabelPrinterUtility

CAUTION Do not apply a strong downward force to the peeler cover while it is open. Doing so may damage the peeler. If the peeling sensor is exposed to strong light such as direct sunlight, the peeling sensor may malfunction and the peeler may not operate correctly. If the media does not peel normally and becomes wound around the peeler roller or the platen, or if there is a paper jam, open the peeler cover and remove the media. If the media, etc., within the peeler cannot be removed, do not apply unreasonable force, but contact your retailer or representative office. When label media or backing paper is wound around the peeler roller, the peeler does not operate normally. Only use the peeler after eliminating the blockage. Allow the backing paper after peeling to hang in a vertical direction of the printer installation surface. Also, when a large quantity of the backing paper after peeling has accumulated, the backing paper does not hang vertically, and the backing paper may become entangled in feet causing the printer to fall or an injury. It is recommended that the backing paper be disposed of before it has accumulated in a large quantity. If the peeled label media is removed by peeling in the parallel or downward direction, deviation of the media may occur. Be sure to peel away from the backing paper in the upward direction. If the peeler cover is left closed for a long period of time, the components around the platen may become deformed. During transport, keep the peeler cover open. External media feed cannot be used. Set label media with a roll outer diameter of φ127 or less in the printer for use. If the media width changes after long-term use, there is a possibility that printing or feeding will be affected, depending on the state of wear of the platen and the peeler roller. If it is not possible to clean the platen and peeler roller or to improve the adjustment of the head balance and the media guide, it is recommended that the thermal head or the platen be replaced. It is recommended that the platen be replaced after 5 to 10 km (50,000 to 100,000 labels of length 10 cm), because the printing quality is affected. If dust or dirt is adhering to the peeling sensor, the peeling sensor may not operate correctly, so it should be periodically cleaned. If label media adhesive or paper dust are deposited on the platen, the peeler roller or the media hold-down bar, deviation of the peeling position or peeling defects may occur, so it is recommended that they be cleaned when replacing the media. Refer to 11. Maintenance

2. Configure pairing settings

Confirm that Bluetooth is enabled on the host PC before searching for Bluetooth devices. This product will be indicated as “CL-E300_XX” or “CL-E303_XX” (XX is the last 2 digits of the unique Bluetooth device address) when detected in the device search. Select this product from among the detected devices.

2. Configuring pairing settings

Normally, selecting the printer during device detection will transition directly to pairing settings. CAUTION Some host PC configurations and models may not transition directly to pairing settings after the printer is selected during device detection. — 126 — Functions

1. Communication status display by LED

2. Security settings available (authentication, encryption, and device search

restriction) This product is provided with the two security levels of high and medium. The difference between the security levels is whether or not there are authentication requests and encryption requests. An authentication request is required when starting a service search or iAP/ SPP connection, and there is the following relationship for the authentication and encryption requests of the two security levels, including whether or not there is support for SSP on the device. Device without support for SSP Security setting Service search authentication request PIN code connection authentication SPP connection authentication request Encryption request Medium High

Yes Yes Yes Yes Yes Yes Yes Device with support for SSP Security setting Service search authentication request PIN code connection authentication SPP connection authentication request Encryption request Medium High

3. Pairing information retention function (maximum 8; most recent 8 if 8 is exceeded)

4. Connection approval by means of secure simple pairing (SSP) or a PIN code

The initial value of the PIN code is the last 4 digits of the 12-digit address (excluding the colon “:”) that is printed by a self test print, and if the PIN code contains any alphabet letters (A to F), specify them in uppercase. (Example: When 01:23:45:67:89:AB, the initial PIN code is 89AB.) For a host with the SSP function, pairing is achieved without any additional operation. For a host without the SSP function, you will be asked for a PIN code so enter the PIN code. — 127 —

5. Connection update function

Executing “Bluetooth connection update mode” in the online configuration mode transitions to the discoverable state. Also, executing “All Bluetooth pairing information deletion mode” in the same configuration mode deletes the saved pairing information and transitions to a discoverable state. If the paring information on the host is deleted, the device may not be displayed when you perform a device search again unless you also delete the pairing information on the printer. If that happens, delete the pairing information with the connection update switch to transition to the discoverable state.

6. 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 Even when “No” is indicated for a request, do as requested if there is a request from the connected party. Encryption for the security medium setting is enabled only for an authenticated iAP/SPP connection. This function is enabled when shipped from the factory. 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. Ÿ When you want Bluetooth communication to cut off after printing is complete Ÿ When there are multiple iOS devices printing on the same printer Under such conditions, disable auto reconnection. Since processes such as the initial setup of the Bluetooth module are performed when the power is turned on, startup may take several seconds to complete. When large amounts of data will be transferred from a host, perform control such as transfer time and transfer data amount adjustment on the user side so that the transfer data buffers on both the printer and host do not become full. For pairing information deletion and reconnecting, refer to the following. Refer to 8.
