I just hooked it up, and it looks like it is banding. I have tried a head alingment, head cleaning, and auto band adjustment. Especially where there is a gradient from dark to light, you see it. I am testing on Epson semi gloss paper. Any suggestions? please help!!
The guys at ColorHQ where I purchased my printer told me to always use unidirectional printing because bidirectional printing caused visible banding in the shadows. From the Canon IPF5000 Wiki:
"To select Unidirectional printing in the Photoshop plugin, select the Main tab, then click on the Set button under the Media Type dropdown box. There is a checkbox in the lower left corner of the dialog box where you can select Unidirectional printing. For optimal color accuracy when making custom profiles, it is probably best to select Unidirectional when printing out the target, since these subtle changes have been reported to affect colors on other printers."
Also, are you printing from the plugin or through the Windows (or Mac) printer driver?

Please let me know the final outcome so I can add to the Wiki if different than the suggestion given above.
