HP8100 duplexer - minimum paper size

[LordSwad]

I get a warning when printing with 3in x 5in cards on the 8100 that this paper size is too small for the duplexer (it will still print single sided ok). I can't find in the documentation what minimum size the duplexer will handle. I'm trying to print record cards but I don't want to have to buy every size under the sun to find out what the printer can cope with.

Is it an HP Officejet Pro 8100 ? It supports the following sizes for cards

Index: 76.2 mm (3.0 inches) x 127 mm (5.0 inches)

Index: 127 mm (5.0 inches) x 203 mm (8.0 inches)

A6: 105 mm (4.13 inches) x 148.5 mm (5.83 inches)

A4: 210 mm (8.3 inches) x 297 mm (11.7 inches)

Hagaki : 100 mm (3.9 inches) x 148 mm ( 5.8 inches)

O**bleep**u Hagaki: 148 mm (5.8 inches) x 200 mm (7.9 inches)

Index Card Letter: 216 mm (8.5 inches) x 279 (11.0 inches)

It does not say about duplex for cards

According to this User Guide manual for the OfficeJet Pro 8100 printer, only the larger paper sizes are supported by the duplex unit:

The extract above only shows that part of the table which includes 'ticks' in the 'duplexer' column.

The shortest of the sizes shown in the extract is 257 mm (10.12").

I assume that the automatic duplex limitations are associated with the physical distance between various sets of rollers in the paper path.
