APPENDIX D – Paper Quality Guidelines
General
These paper quality guidelines are general recommendations. Paper beyond these specifications may work as
well, however it should be tested before use. Paper is a material that reacts intensively to adverse temperature
and humidity conditions. The observance of proper conditions as defined below is therefore essential for trouble-
free operation of TowerFeed. Please also refer to the corresponding guidelines in the printer manual.
Paper Quality and Surface
Bond type papers and papers with slight rag content are recommended. For papers with high rag content, as well
as very light and air mail papers, feeding tests must be conducted to check for satisfactory performance before
regular use. Paper with embossed or heavy printing should be tested in TowerFeed before use, as well. Papers
with glossy or structured surface are not recommended. Individual sheets in a stack must not be damaged,
warped more than 3 mm (0. 12") at an angle of max. 20° or creased, since all these may reduce the feeding
performance.
Paper Weight
The specified paperweight is 60 - 95 g / m
2
(16 - 24 lb.). Other paperweights must be tested before use.
Tolerance
Paper must be cut to the appropriate size dimension within a tolerance of
±
1.0 mm (
±
0.04"). The paper stack
must be cut square to within a tolerance of 90°
±
0.1°.
Recommended Storage Environment
Temperature:
18°C - 24°C (64°F - 75°F)
Relative humidity:
40% - 60%
