RIBBON SPECIFICATIONS
Appendix C describes the ribbon specifications which must be met to
ensure optimum performance of the HP2566C/HP2567C printer.
Overall Dimensions Overall Ribbon Length:

Ribbon Fabric The ribbon should be .0036 to .0042 inch (.0914 to .1067 mm) thick
nylon fabric. Quality ribbon fabric should have 716 to 742 threads per
in2 (111 to 115 threads per cm2).
Only new ribbon fabrics are recommended for use in the HP256X
printers. Current methods used for re-inking used ribbons do not ensure
complete re-saturation of the ribbon. Excess ink on the surface of the
ribbon tends to come off the ribbon in clumps and contributes to print
bar contamination. Ink build up on the hammers can cause them to fire
incorrectly.
Splices or repair patches in the body of the ribbon material between
conductive pads should also be avoided.

Conclusion Since it is impossible to test all ribbons available for use in the printer,
Hewlett-Packard recommends that ribbons conform to the specifications
outlined in this document for optimum printer performance. The part
number for the recommended ribbon for the HP2566C/HP2567C printer
is 9282-0545A.
