Six Monthly Check
Every six months the printer should receive a complete examination. Check the
external and internal tubing for signs of ageing, kinking or leaking, and have them
replaced if necessary.
Every six months the ink filter unit (IF/01) must be replaced. This involves
opening the print head unit. Unscrew the four screws around the bottom edge of
the print head (not those further up) and lift off the top of the chassis, complete
with keypad, LCD display and electronics. Support the top out of the way or
disconnect the cables - do not let it hang!
Replace the ink filter, checking that it is
installed correct way around (an arrow is
printed on the filter to show ink flow
direction - toward the nozzle plate). To help
eliminate air in the ink system, fill the ink
filter with nozzle cleaner fluid before fitting.
When completed, perform a purge.
