Datamax ST-3210 - Printhead Cleaning

S-Class 41
4.4.1 Printhead Cleaning
Declining print quality (for example, streaking or smudging) is usually
caused by a surface build-up of dirt on the printhead; see Section 3.5.2. If
left unattended, this build-up can lead to permanent printhead damage.
Clean the Printhead as follows:
 Turn ‘Off’ and unplug the printer. (ST Models: Raise the access
cover; see Section 3.2.)
 Slide the Printhead Latch to the ‘Unlocked’ position and then raise
(or, in the case of SV Models, lower) the Printhead Assembly.
 Using a cotton swab dampened
with isopropyl alcohol gently wipe
the Printhead surface, paying close attention to the Burnline,
cleaning until all build-up is removed.
CAUTION
NEVER use a sharp object to clean the Printhead. Damage can
result.
