3.4. Installing Paper
Please ensure that the correct grade of paper is used with the APOS printer (see §2.3.2). It is
extremely easy to load a new paper roll into the printer by following these simple steps:
• Open the cover and remove the old paper core
• Drop the new roll into the reservoir so that it will rotate in the correct direction (i.e. so that the
emulsion side of the paper rests against the printhead)
• Hold the front edge of the paper outside the main cavity at the front of the printer
• Close the printer cover
3.5. Maintenance
The APOS printer is a high reliability unit which requires very little maintenance but may benefit
from cleaning as detailed below.
3.5.1. Cleaning the Printer
The external surfaces may be kept clean by wiping with a lightly damp cloth but this must only be
done after unplugging all electrical connections. Great care should be taken to ensure that the
inside surfaces are kept dry at all times and that the external surfaces are thoroughly dry before re-
making any electrical connections.
3.5.2. Cleaning the Printhead
Depending of the environment in which the printer is used, the printhead may accumulate dust.
Therefore it is necessary to clean it periodically in order to maintain a good print quality. The
cleaning period is dependent on the environment and the usage of the printer but the printhead
should be cleaned at least once a year or up to once a month in heavy duty applications. The
printhead should always be cleaned immediately if the print becomes visibly fainter due to
contamination of the printhead. To clean the printhead:
• Switch off the printer. Never clean the head immediately after printing, the printhead may
be hot.
• Open the printer cover and remove the paper roll.
• Clean the heating dots of the head with a cotton stick containing an alcohol solvent (ethanol,
methanol or IPA) but do not touch the printhead with you fingers !
• Allow the solvent to dry
• Reload the paper and close the cover
