The e-mark is communicating with the user by acoustic signals and the lightpipe (LED bar around the e-mark). The colours and position of the lights, as well as the acoustic signals have different meanings. In general, red indicates a problem (no cartridge inside or very low battery) and yellow is a warning, e. g. that the battery is low. Blue is related to the WiFi connection and data transfer and green tells you that the e-mark is ready or battery is full. Please find the description of the different signals below.
What does the beeping mean?
Whenever an imprint is successfully transmitted to the e-mark or an imprint is finished, the e-mark beeps. When making a two- or three-line imprint, the beeps of the e-mark tell you when to change direction and move to a new line. When the e-mark keeps beeping and blinks red, this is a warning to put the e-mark into its docking station. Otherwise the print head may dry out, causing bad imprint quality. If you do not like the sound of the e-mark, it can be turned off in the settings.
What does a blue light mean?
Blue light refers to the connection and data transfer. An ongoing blue blinking around the e-mark indicates that an imprint is transferred from the App to the e-mark. The steady blue light on the back of the e-mark indicates that the e-mark is connected to a mobile device via WiFi.
What does a green light mean?
On the back side of the e-mark, a green light indicates that the level of battery is above 25 %, which turns yellow below a level of 25 % and red when reaching 10 %. During printing you will see a green light on the side which indicates that the e-mark is printing.
What does a red blinking light in the front of the e-mark mean?
It indicates that no cartridge is inside the e-mark. If a cartridge is inside and the light is still blinking red in the front, the cartridge is probably not in the right position and needs adjustment.
What does a yellow blinking light in the front of the e-mark mean?
It indicates that a wrong cartridge is inserted (not an original COLOP cartridge). Please only insert original COLOP e-mark cartridges.
If you have inserted an original cartridge, please check if a software update is available and update the firmware if necessary.
