Media Limits For Stapling; Stapler Operation - Lexmark W850n Manual

While if sheets with different widths are present on the compiler unit assembly, stapling is stopped when a
different width is detected. Such different-width sheets are forcibly ejected to the stacker media bin.

Media limits for stapling

The number of sheets to be stapled is limited to prevent damage to the stapler.
•
If the number of sheets of one set to be stapled exceeds the limit of the compiler unit assembly, the
exceeding sheets are not stacked on the compiler unit assembly, and are forcibly ejected to the stacker
media bin without being stapled.
•
After the forcible ejection of media, if the number of following sheets of one set to be stapled exceeds the
limit of the compiler unit assembly, the exceeding sheets are also ejected forcibly to the stacker media bin
without being stapled.
•
After that, even if the number of following sheets of one set to be stapled falls within the limit, the sheets are
also ejected forcibly to the stacker media bin without being stapled.
Upper limit of compiler unit assembly media capacity when stapling: default: 50 (variable (10 to 100) by the non-
volatile memory).

Stapler operation

The stapler stays at the front home position, that is, at the front staple (corner) position when the power is
turned on.
The stapler starts stapling when a set of sheets to be stapled is stacked on the compiler unit assembly.
The stapler does not move during stapling in the front staple mode.
In any mode other than the front staple mode, the stapler moves to the specified position, and then perform
stapling.
