Ricoh EMP 156 User Manual page 157

If the "Sample" button or the "Auto Proof Sample" function is used while
printing in duplex mode on pre-printed paper, the print image will not be
printed to the intended paper side.
Do not use the "Sample" button or the "Auto Proof Sample" function when
using paper with predetermined page numbering.
MOP and Reverse Page Order Limits
There are many complex factors in calculating the estimated Multiple Output
Printing (MOP) or Reverse Page Order limits. The disk partitioning scheme,
fragmentation, page block boundaries, edge-to-edge, printer emulation, and
sheet/page object overhead all affect the actual MOP or Reverse Page Order
limit as seen by the end user. Therefore, the stated MOP or Reverse Page
Order limits are defined in terms of "at least this many" sheets per MOP or
Reverse Page Order sets.
:
NOTE
A sheet is defined as a physical paper sheet. Although a duplex sheet may
print data on the back side of the sheet, the sheet is still considered one (1)
physical sheet in this context.

Accounting Slip Sheet
Client IP Address, Client Network Name, User Name, Document Name, Department
Name, and Charge Code are not printed on the Accounting Slip Sheet when the print
job is sent from the printer driver. (User Name and Document Name may be printed if
the LPR protocol is used).
When using Transit Pass Unit Type 156 and Finisher
When an image such as bold lines, etc., are printed on one side of the folded
centermost sheet, and the other side of the page is blank, the bold lines, etc.,
may be slightly transferred to the blank page (ghost print). When using the
Finisher, please confirm by printing one set in beforehand. Please lower the
print density of the printer if ghost-print occurs.
When stitching more than 20 sheets of 75g/m2 (20lbs.) or less paper at the
top/side/corner, paper edge alignment may be uneven at the stitched corner,
leading to paper jams. It is recommeneded to use 75g/m2 (20lbs) or heavier
paper.
