Aligning sheets in a sheet restacking tray using rotating helical brushes

A sheet registering apparatus, comprising:

• a sheet-receiving tray;
• registration guides connected to said sheet-receiving tray and defining a corner in said sheet-receiving tray;
• a first rotating brush at a left side of said sheet-receiving tray, said first rotating brush having a vertical shaft relative to a base of said sheet-receiving tray and bristles attached to said vertical shaft in a right-hand pitch helical pattern;
• a second rotating brush at a right side of said sheet-receiving tray, said second rotating brush having a vertical shaft relative to said sheet-receiving tray and bristles attached to said vertical shaft in a left-hand pitch helical pattern;
• and
• a third rotating brush at a side of said sheet-receiving tray opposite said corner, said third rotating brush having a vertical shaft relative to said base of said sheet-receiving tray and bristles attached to said vertical shaft in a helical pattern.

A method of collecting and aligning print media sheets, said method comprising:

• receiving a print media sheet into a sheet-receiving tray;
• engaging said print media sheet with a tamper mechanism comprising a first tamper device adjacent to a first side of said tray, a second tamper device adjacent to a second side of said tray, said second side being opposite said first side, and a third tamper device adjacent to said first tamper device;
• and
• moving said print media sheet into said sheet-receiving tray toward registration guides, said registration guides defining a corner in said sheet-receiving tray.
