operated repeatedly, until a ‘

select pen park ON, and the ENTER key is operated. This causes the pens to fan out, allowing easy access
(figure 3.2.5). Further movement of the pens is inhibited until pen park is selected OFF.
CARTRIDGE REPLACEMENT
Once the printhead is parked, the exhausted colour cartridge can be removed by gently pulling on it. The new
printhead is now taken out of its package (using the tip protection clip) and inserted onto the colour-select motor
shaft (figure 3.2.5). Restrain the cog (drive gear) behind the cartridge with one finger, and gently rotate the
colour cartridge until the tab at the rear of the cartridge drops into the associated hole in the cog. It should be
ensured that the cartridge is properly retained.
When the recorder is mounted in a sloping panel, the intensity of the printed dots may be reduced, As the rear
of the case is lower than the front. See section 6 for dot intensity adjustment details.
