e of treatment fluid by such accumulations. It is desirable to maintain the means of applying treatment fluid and the treatment fluid itself in an uncontaminated state to provide consistent printhead cleaning over the life of the printer. Also, metering the amount of treatment fluid applied in wiping is recognized as important. Consistent optimal cleaning effectiveness as well as print quality can be compromised by application of too little or too much treatment fluid. Too little treatment fluid results in less effective residue removal allowing undesirable accumulation. Too much treatment fluid can result in one or more nozzles being at least temporarily disabled due to excess treatment fluid being pushed into the nozzle by the wiper, or drawn into the nozzle by negative pressure associated with operation.
In sum there are many problems, including identifying optimal ways of applying treatment fluid to enhance wiping effectiveness, that have been identified but not resolved in known cleaning systems. It is therefore recognized that an improved cleaning system, particularly for printers using pigment-based inks employing high solids content and dispersants, is needed to provide and maintain optimal functioning of thermal inkjet printheads.

1. Field of the Invention
The present invention relates to a toll pass display assembly and system and, more particularly, pertains to removably retaining a toll pass in position for being scanned when driving a vehicle.
2. Description of the Prior Art
The use of other vehicle pass holders of known methods and apparatuses is known in the prior art. More specifically, other known vehicle pass holders of known methods and apparatuses previously devised and utilized for the purpose of holding toll pass card in place are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
