5-10 Cleaning Clogged Ink Jets
◆ Cleaning the Service Station doctor blade — with use over
time, the doctor blade that cleans excess ink from the ser-
vice station wiper blades will accumulate a buildup of ink.
This will reduce the cleaning effectiveness of the doctor
blade, resulting in “dirtier” wiper blades and more clogged
printhead jets. To keep the inkjets clear, regularly inspect and
clean the doctor blade with SolaChrome-HR Cleaning
Solvent.
