Frequently Asked Questions - EC-80320 EC Line

How do I load labels into the EC-80320?

Open the top cover, remove the media guide, place the label roll on the spindle, adjust the guides to fit the label width, and feed the label through the sensor and exit slot. Close the cover and press the feed button to align.

What type of labels can I use with this printer?

The EC-80320 supports thermal transfer and direct thermal labels. You can use paper, synthetic, or polypropylene labels on rolls with a maximum width of 80 mm. Ensure labels have a gap or black mark for sensor detection.

How do I connect the printer to my computer?

Use the provided USB cable to connect the printer to a USB port on your computer. Alternatively, you can use the serial RS-232 port. Install the appropriate driver from the included software CD or download from the EC Line website.

Why is the printer not printing?

Check if the printer is powered on and the USB cable is connected. Ensure labels are loaded correctly and the sensor detects them. Verify that the print head is clean and the ribbon (if using thermal transfer) is installed properly. Also check that the driver is selected in your software.

How do I clean the print head?

Turn off the printer and let it cool. Use a cotton swab dipped in isopropyl alcohol to gently wipe the print head in one direction. Allow it to dry completely before printing. Perform this regularly to maintain print quality.

Can I print without a ribbon?

Yes, if you use direct thermal labels. Ensure the printer is set to direct thermal mode in the settings. Direct thermal labels darken when heated, so no ribbon is needed. However, the print may fade over time.

What software can I use to design labels?

The printer is compatible with popular label design software like BarTender, NiceLabel, or Seagull Scientific. You can also use generic Windows label printing applications. The printer emulates ZPL and EPL commands for flexible integration.

How do I change the ribbon?

Open the top cover, remove the empty ribbon core, unwind the new ribbon and attach it to the take-up spindle. Route the ribbon through the print head assembly according to the diagram inside the printer. Close the cover and feed a few labels to seat the ribbon.

The labels are printing with poor quality, what should I do?

Check the print head cleanliness and condition. Adjust the darkness/contrast setting in the driver or software. Ensure the ribbon and labels are of good quality and compatible. Also verify that the platen roller is clean and not worn.

How do I reset the printer to factory settings?

Turn off the printer, press and hold the Feed button while turning on the printer. Wait until the LED flashes, then release the button. The printer will reset to default settings. Note that this will erase any custom configurations.

The printer's information is listed in the main interface, the left side of which is the model and description and the right is the IP and MAC address. What's more, the assign mode (dynamic/static) is noted behind the IP address.

Fig2-12 Setting printer's IP address

1) Correlative description for IP address settings

In order to search and set printer's IP address conveniently for the first time, the factory default setting is DHCP mode which assigns IP address dynamically. If there is no DHCP server in the connected LAN and printer is set to DHCP mode as well, then it will use the internal pre-set address (IP: 10.0.0.1, Subnet Mask: 255.255.255.0) automatically.

It is suggested that printer's IP set to static in actual usage, which can cut down the time when initializing the Ethernet interface as the printer is turned on and prevent IP conflicts (The dynamic address used in printer may conflict with another one). The network segment part of the IP address and Subnet Mask must be the same as those of PC connecting with a printer.

For example, the address of working PC is 192.168.0.1/255.255.255.0 (IP/Subnet Mask), then which of printer should be set to 192.168.0.x/255.255.255.0 (x=2\~254 and should avoid the IP in used. It is not restricted for NetFinder to search printers in the same network but different segment parts (can not stride gateway). Relative glossary of IP address may refer to corresponding information.

2) Setting printer's IP address

Select the printer information to be modified (black frame appears), click "Assign IP" button. Set the IP in the dialog box appearing.

Check the "Use DHCP" if need to assign dynamic address, the settings above will be disabled

automatically. Please make sure there is a DHCP server in the network, or the printer can not receive an effective IP address.

When to specify static address, uncheck "Use DHCP" and fill in "IP address", "Subnet Mask" and "Default Gateway". If there is no gateway in the network, fill 255.255.255.255 in the "Default gateway". "IP address" and "Subnet Mask" should obey the assigning rules of local LAN (Ethernet), please enquire the administrator of networks which the printer connects to for more details.

Click "OK" to send address setting information to the specified printer. The printer takes response after "Close this window on success" is checked, and then this dialog is closed automatically. Select "Reload Timer" then the software will wait for the printer's response. Generally, printer will take response in a circle time if network connection is correct.

Click "Cancel" if you abandon the modification.

Chapter6 Troubleshooting and Maintenance

6.1 Maintenance

To prolong the printer's life, make sure that the printer is well away from heaters and other sources of extreme heat, and the surrounding area is clean, dry, and free of dust.

Cleaning paper case and thermal head periodically is the main task of maintaining the printer. We will talk with this problem in this section. It is noted that make sure to power off the printer before maintenance.

Clear printer:

Dirt and dust does the most damage to the printer. Clean the paper in the printer and accumulated dirt in the thermal head as well despite the outer case of the printer prevents greater part of dust from invading.

Clean printer case:

Remove the dirt in the printer case with clean, soft cloth, and take out the paper pieces with a nipper.

Attention: Be careful not to scratch the printer parts when cleaning.

Clean the printer periodically according to the prescription as follows.

Periodical cleaning: Once every 6 months or 300 work days

Cleaning tool: Dry cloth (Soft cloth if metal parts)

6.2 Error Message on the Control Panel

When the malfunction is occurred, the printer will be off-line and give an alarm through indicators. You can make out different malfunction through the Table A-4 shown below.

Table A-4: Error message on the control panel

Error indicator	PAPER OUT indicator	Malfunction	Solution
Blink fast OFF	Cutter error Re-posit the cutter
ON OFF	Cover is open Close the	cover tightly
OFF ON	Paper near end Load the	paper again
ON ON	Paper out Load the paper	again
Blink	OFF	Thermal head over hot	Recover automatically

6.3 Cutter Jammed or Error

If the auto-cutter was jammed, open the upper cover and take out the paper. If the upper cover can not be opened and the cutter still can not return to the normal position after restarting the printer, pull out the small cover upper the auto-cutter so that the cutter can

come out. Rotate the white plastic gear by hand in the direction of arrow to make the cutter return to the normal position which is shown as figure 6-1.
