the paper supply is depleted referring to fig3 through 5 three different bucket positions are illustrated for three different receipt printing machine orientations associated with this invention fig3 depicts a feed bucket 21 that is angled at 14 u00b0 with respect to the horizontal plane which is typical of a machine orientation mounted to the top of a desk this position is given the designation 34 aa 34 fig4 depicts a bucket 21 that is at a substantially flat 0 u00b0 angle with respect to the horizontal plane which may also be characteristic of a desktop mounted receipt printing machine this position is given the designation 34 bb 34 fig5 depicts a bucket 21 that is at a substantially right angle 90 u00b0 with respect to the horizontal plane which is typical of a receipt printing machine that is wall mounted this position is given the designation 34 cc 34 referring to fig6 an enlarged view of the supply bucket 21 shown in fig3 through 5 is shown the supply roll 15 and the reflective sensing unit 11 are illustrated in three respective designated positions 15aa 11aa phantom view 15bb 11bb solid view and 15cc 11cc phantom view all of which correspond to the different bucket 21 orientations aa bb and cc fig3 through 5 the position supply roll 15aa 15bb or 15cc within the bucket 21 moves in accord with the orientation of the printer in respective positions aa bb or cc regardless of the orientation of the printer the reflective sensing unit 11 may readily be adjusted to maintain a reliable low paper condition signal referring now to fig7 there is shown a flowchart of the steps of the software implemented 34 de bounce 34 system that forms a part of the present invention two signals output status.
