DRIVE CLEANING

Follow the procedure below to do drive cleaning. Here are some important points you should
know about drive cleaning.
Drive cleaning should be done only after head cleaning and head flushing fail to clean
the print heads successfully.
Drive cleaning is done by changing a bit switch setting in the SP mode and should
always be done by the service technician.
Drive cleaning forces the piezo element to switch off and on repeatedly to force ink out
of the nozzle ports. (The piezo element does not operate during head cleaning or head
flushing done with the operator panel or the printer driver.)
Drive cleaning consumes more ink than either head cleaning or head flushing and
requires more time to complete.
Only one print head at a time can be cleaned with this procedure.
Before you do this procedure, make sure the print cartridge of the color that is
causing problems is not almost empty. Drive cleaning cannot be performed if a print
cartridge is almost empty.
