Printing Preparation Process
The printer must be set up according to the following process before printing can be performed.
Refer to the description of each section for detailed information on each step of the process.
Loading Paper
Loading roll media (Standard model and cutter model)
  • 1.Press the cover release buttons on both the right and left sides to open the top cover.
  • CAUTION
    • Note the following precautions when the top cover is open.
      • Do not touch the thermal head.
      • Do not touch the cutter blades.
  • 2.Insert the media shaft through the core of the media roll and then install the media shaft guide.
    • The media shaft is designed to accommodate both 1-inch and 1.5-inch media roll cores by flipping it upside down. The media shaft has markings indicating which side supports the different core sizes. Select the media shaft orientation in accordance with the size of the media roll core.
  • Notes
      • Use media rolls that have the print surface on the outer side. Do not use media rolls that have the print surface on the inner side. Labels may peel when such media roll is back-fed.
      • If the media shaft is not installed correctly, the top cover or bottom of the printer will prevent media from feeding properly and cause paper jams.
  • 3.Set the media so that the media shaft guide is on the right side of the media when looking at the front of the printer.
  • 4.Press the media shaft guide onto the media roll so that the center of the media aligns with the center of the media shaft and then set the media into the printer.
    • 1.Assemble the media shaft and media shaft guide.
    • 2.Insert the media shaft through the core of the media roll and then set the assembly into the printer.
    • 3.Set the media in the printer and slide the media to the left from the perspective of looking at the front of the printer. Insert the media shaft guide into the paper at this position.
  • Notes
    • Too much abutment force by media shaft guide may cause improper feeding of media, which may negatively impact print quality.
  • 5.If using an integrated cutter model, insert the media through the cutter slit.
  • Notes
    • Insert media into the slit correctly. Failure to do so may result in improper feeding of media, which may cause paper jams.
  • 6.Make sure the media is in abutment with the left media guide and then adjust the position of the right media guide in accordance with the media width.
  • From the front of the printer, set in front of the edge of media by approximately 10 mm.
  • Notes
    • Too much abutment force of the right movable paper guide may cause improper feeding of media, which may negatively impact print quality.
  • 7.Slide the head balance adjustment slider located near the thermal head along the media size scale (inch) so that the position of the notch in the slider matches the media width.
  • CAUTION
    • Adjust the head pressure horizontal balance carefully so as not to damage the thermal head.
      Damaged thermal heads will result in poor printing, paper jams, and malfunction.
  • 8.Close the top cover.
  • Press the push marks on left and right sides at the top of the top cover and ensure that the top cover hooks on each side lock securely.
  • CAUTION
    • If the top cover is not securely locked, this may cause print errors, paper jams, and malfunction.
Loading Paper (Peeler model)
  • 1.Check whether the print mode is set to peeling mode.
  • Check whether the value of “Function Select” in the “After Print Setup” menu is set to “Peel”.
  • CAUTION
    • The peeler model can only be used in the peeling mode.
  • 2.Perform the operations of procedure 1 to procedure 4 in section “3.2 Loading Paper”.
  • 3.Peel the label from the backing paper.
  • Make sure that the area with the backing paper only is at least 20 cm from the end of the backing paper (illustration A).
  • 4.Grip the opening handles with both hands, and gently pull forward.
  • CAUTION
    • If the media hold-down bar is held down with a finger and the peeler cover is opened, there is a possibility of damage to the media hold-down bar.
    • Do not apply a strong downward force to the peeler cover while it is open. Doing so may damage the peeler.
  • 5.When the peeler cover is open, pass the backing paper between the peeling plate and the peeler roller.
  • 6.Pull down the backing paper further, so that it extends at least 7 cm from the peeler cover (illustration A).
  • 7.Make sure the media is in abutment with the left media guide and then adjust the position of the right media guide in accordance with the media width.
  • At this time, check that the label is not over the bottom sensor or fed past the bottom sensor (check that only the backing paper passes the bottom sensor).
  • Notes
    • Do not push the media guide against the media with too much force. This may negatively impact print quality.
    • If the label is over the bottom sensor, it may not peel off correctly during the first paper feed.
  • 8.Slide the head balance adjustment slider located near the thermal head along the media size scale (inch) so that the position of the notch in the slider matches the media width.
  • CAUTION
    • Adjust the head pressure horizontal balance carefully so as not to damage the thermal head.
      Damaged thermal heads will result in poor printing, paper jams, and malfunction.
  • 9.Close the top cover.
  • Press the push marks on left and right sides at the top of the top cover and ensure that the top cover hooks on each side lock securely.
  • CAUTION
    • If the top cover is not securely locked, this may cause print errors, paper jams, and malfunction.
  • 10.Pull the backing paper extending from the peeler cover downwards, and eliminate the slack.
  • 11.Close the peeler cover.
  • 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.
  • Notes
    • 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.
CAUTION
  • Do not apply a strong downward force to the peeler cover while it is open. Doing so may damage the peeler.
  • Ensure that the backing paper does not block the backing paper outlet after it is peeled off, and that it hangs perpendicular to 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 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.
Notes
  • Factors such as label media quality, adhesive, surface treatment, and the humidity and environmental temperature where the device is being used may prevent the label from peeling off properly.
  • 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.
  • 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.
  • 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.
Loading fanfold media
  • 1.Press the cover release buttons on both the right and left sides to open the top cover.
  • 2.Insert the fanfold media through from the external media feed port at the back of the printer.

  • Use a label detection sensor (Transparent sensor) for label media gaps and media with black marks.
  • Use the continuous media detection sensor (Reflective sensor) for continuous media with no notches or black marks.
  • Use a label detection sensor (Transparent sensor) for fan fold media.
  • Cutting at perforated lines is not recommended because an extremely large amount of paper dust and paper scraps will be generated.
    Furthermore, cleaning the platen at the start of use is recommended.
  • If the label pitch is 1 inch or less, configure an accurate label pitch with the [Small Media Adjustment] setting.
  • Use carbon-based ink with an OD value of at least 1.5 to print black lines.
  • The stop position and cut position may change depending on the width or type of media that is used.
    Adjust these positions using the Paper Position setting.
  • Media with perforated lines (including fanfold paper) cannot be used in the peeler model.
Adjusting Media Sensor Positions
Three types of media sensors can be used: the label detection sensor (transparent sensor), the black mark detection sensor (reflective sensor), and the continuous media detection sensor (reflective sensor).
The printer comes from the factory equipped with the label detection sensor (transparent sensor). Depending on the media used, it may be necessary to switch to using the black mark detection sensor (reflective sensor) or the continuous media detection sensor (reflective sensor).
Range of Paper Sensor Adjustment
The following figure illustrates the range of media sensor adjustment.
When using a label detection sensor (transparent sensor)
  • Adjust the position of the bottom sensor and upper sensor in accordance with the media width.
  • Be careful that media with black marks does not pass the media sensor.
  • Move the bottom sensor and upper sensor by the same number of steps from the position of the triangle (▲).
  • The range of bottom sensor and upper sensor horizontal adjustment is 10 steps between the triangle marks (▲).
  • Use a pen or other object with a narrow tip to unlock the bottom sensor and then reposition it.
    Lock the sensor in place once the new position has been determined.
  • CAUTION
    • Attempting to move the sensor while still locked may damage it.
  • Notes
    • The bottom sensor and upper sensor must be in alignment with each other.
When using a black mark detection sensor (Reflective sensor)
  • Set the bottom sensor at a position so that the center of the sensor window is in alignment with the center of the black line.
  • Notes
      • Do not install the upper sensor directly above the bottom sensor. Normal operation may not be possible.
When using the continuous media detection sensor (reflective sensor)
  • Move the bottom sensor close to the center of the width of the media.

If it is dirty, remove the dirt with the attached head cleaner (Sold separately).
If a label is stuck to the thermal printhead remove it.
Note: Do not use a metal object to remove a label stuck to the inside of the printer.
(This may damage the thermal printhead.)
If adhesive label material is stuck to the thermal printhead, remove it with a soft cloth soaked in ethyl alcohol.
Is the printer’s head pressure balance correct for the width of the media that is used? Use the slider to adjust the head pressure of the thermal print head.
Indication Check Corrective action
The printing position changes. Are the media correctly set? Correctly set the media.
Is the platen dirty?
Is it deformed?
If it is dirty, clean it with ethyl alcohol.
If it is deformed, replace it.
Note: Consult with the dealer that supplied the printer concerning the replacement.
Are the data contents and the command signals from the host appropriate? If an error message is displayed, check the content of the software and the communication status set by the host computer.
Are the menu values set appropriately? Set the correct menu values using the operating panel or the host computer.
Are the sensitivities of the media sensors appropriate for the media that is used? Set the media sensitivity to appropriate values.
If this does not solve the problem, change the “Sensor level” that is set in the “System setup.”
Indication Check Corrective action
A cutter error occurs. Is there any jammed media? If the issue is not resolved even after removing the jammed media and turning off and restarting the power, enable the cutter lock release mode and release the cutter lock.

Pairing operation
You need to perform the operations below the first time you establish a Bluetooth connection for Bluetooth data communication.
  • 1.Detect Bluetooth devices
  • 2.Configure pairing settings
  • 1.Detecting Bluetooth devices
  • 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.
Notes
  • Some host PC configurations and models may not transition directly to pairing settings after the printer is selected during device detection.
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 No Yes Yes Yes
      High 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 No No Yes Yes
      High Yes No Yes Yes
  • 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.
  • 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.
Notes
  • 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.
    • 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.
  • 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.
