Further details to solve eventual problems
If the print looks squashed
Check that the paper roll is sitting correctly in the paper
well and that the roll is the right way up. The paper should
be feeding off the bottom of the roll into the back of the
mechanism NOT off the top of the roll. Remove paper and
reload if necessary.
The printer prints “?” “!” or “*” in
place of the transmitted characters or it
does not action commands.
Check the handshaking line, parity setting and baud-rate.
The different characters denote particular errors: “?” -
parity error, “!” - framing error, “*” - over run error.
Note 1: in any case make sure you use thermal sensitive paper and that the paper roll is well set in its
bucket. Check that the sensitive layer of the paper is on the print-head side
Note 2: when resetting the printer, every running operation is stopped and all information sent before
resetting is lost.
8 CLEANING YOUR PRINTER
The A630/A631 printer is a highly reliable unit, which requires very little maintenance but will benefit
from cleaning as described in the next sections.
Before cleaning, unplug all electrical connections.
8.1 Cleaning the printer
Keep the external surfaces clean by wiping with a lightly damp cloth. Make sure that the inside surfaces
are kept dry at all times, and that the external surfaces are thoroughly dry before re-connecting.
8.2 Cleaning the print head
Depending of the environment in which the printer is used, the print head may accumulate dust. Therefore
it is necessary to clean it periodically in order to maintain a good print quality. The cleaning period
depends on the environment and the usage of the printer, but it should be cleaned at least once a year or up
to once a month in heavy-duty applications. The print head should always be cleaned immediately if the
print becomes visibly fainter due to contamination of the print head.
To clean the print head:
Switch the printer off.
Never clean the head immediately after printing, it may still be hot.
Open the cover of the printer and remove the roll of paper.
Clean the heating dots of the head with a cotton stick and a little alcohol solvent (ethanol, methanol or
IPA), but do not touch the print head with you fingers!
Allow the solvent to dry
Reload the paper and close the cover
