Appendix

Sheet creation reference
You can use a sheet that you make yourself with this device in addition to the optional sheets that
we offer. If you make your own sheet, follow the specifications below.
(1) Sheet size
Height 110-335.6mm(4.3-14 inches), Width 63.5-228.6mm(2.5-9 inches)
However, Feed Length (L) must be
Do not cut or round the corners on the reference side (timing mark side). (See P.iv)
(2) Weight and thickness
g/m (grams per sheet)
2
mm (thickness)
(3) Paper quality
OCR paper, quality paper, or recycled OCR paper.
(4) Printing ink (printing surrounding mark fields)
When the wavelength of the OMR reading sensor light source is 940nm, use spectrum band
B900 to measure the PCS and use ink at PCS 0.15 or less. Print timing marks in ink at PCS
0.85 or higher.
When the wavelength of the OMR reading sensor light source is 660nm, use spectrum band
B680 to measures the PCS and use ink at PCS 0.15 or lower. Print timing marks in ink at PCS
0.85 or higher.
(5) Printing position accuracy
Parallelism
Perpendicularity
Other
(6) Prohibited printing zones
Do not print between timing marks, or between the top-end (bottom-end) timing mark and
the top edge (bottom edge) of the mark sheet.
Top-end margin*:
Bottom-end margin:
Side margin:
(7) Direction of paper grain
Feed a sheet in the direction of its grain to eliminate curling.
Width (W) × 1.3.
84 - 157
0.1 - 0.19
Adjust printing parallelism for timing marks and data marks 0.2mm or
less based on the cutting edge of the timing mark side.
Adjust printing perpendicularity for timing marks and data marks 0.2mm
or less based on the cutting edge of the timing mark side.
Adjust to ±0.2mm or less of specified measurements unless otherwise
specified.
9mm or more from the top edge to the first timing mark.
9mm or more from the last timing mark to the bottom edge.
4mm or more on the opposite side of the sheet's standard
edge.
