What functions are available in the firmware to adjust the printer for optimum print quality?
There are two types of adjustments available in the firmware to optimize image quality: Printhead Alignment and Banding Adjustment. Printhead Alignment adjusts the timing of the firing of the nozzles so that straight vertical lines are actually straight. Banding Adjustment adjust the paper feed mechanism precisely so that there is no horizontal banding with the multiple passes made by the printhead as it moves back and forth to print a section. Remember that the highest quality setting in the Photoshop plugin involves 16 passes of the printhead to print any area (32 passes for iPFX100 printers with Canon Media Types); if the feed amount between passes isn’t exactly right you will get some degree of banding. Note: According to Canon Tech Support, the banding adjustments are per media type. The last adjustment done (either manual or automatic) will over-write the previous adjustment for that media type. Posters to the Wiki have found that this is clearly true for the Far End Feed Adjustm
