ABSTRACT:
A sheet feeder in a printer has a sheet loader, a pickup roller for feeding a cut sheet from the sheet loader, and a sheet feed roller for feeding the cut sheet supplied from the pickup roller for printing thereon data by a printing head. The pickup roller first feeds the cut sheet toward the sheet feed roller which rotates in a reverse direction, whereby the leading edge of the cut sheet is abut to the sheet feed roller. The pickup roller is then stopped and released from the cut sheet whereby a skew of the cut sheet is corrected. Subsequently, the sheet feed roller rotates in the forward direction to feed the cut sheet.
