If You Have Problems Reseating a Printhead
When printheads are installed, in extreme circumstances it is possible
that the printer will not recognise them. This will be visible on the
front panel with the message “Replace p
ULQWKHDG´ RU³&KHFN SULQWKHDG /
Abort
´ where one or more of the squares are flashing. Each square
represents a printhead, with the flashing ones representing printheads
where the printer has detected a problem.
When you reseat or replace a printhead, the flashing filled square
changes, for one or two seconds, to an hour-glass. At this point, the
printer is testing the printhead. Don’t remove or insert another
printhead while this test is being done.
■ If the test is successful, the hour-glass reverts to its normal
nonflashing filled state.
■ If the test fails, the hour-glass will change back to a flashing filled
square. To correct this, make the following checks:
1 Remove all four printheads completely from the printer. On the front panel
the displayed message will change to show four flashing lights.
