Colop e-mark User manual

Causes
Make sure the ambient temperature is within the
recommended operating temperature. Excessively high
temperatures accelerate the desiccation process, while too
low temperatures can cause the ink to freeze. If the cartridge
was exposed to such a temperature, place it in an operating
temperature environment and allow it to acclimatize for a
period of time (at least half an hour).
After a shutdown period of several days, the print head may
be dried out.
If the e-mark hasn`t been into the docking station he will dry
out.
If the docking station's protection cap does not seal properly,
it may cause the printhead to dry out.
If the protection cap of the docking station is too dirty, it may
cause the printhead to dry out.
