C–40 Appendix C – Continuous Form Stacker
Test Data
Media tested: medium weight bond (18–24 lb.) and heavy
weight bond (>24 lb. and <40 lb.)
Under nominal temperature and humidity
1 mis-stack in 6000 pages
1 mis-fold in 3000 pages
Under conditions of extreme temperature and humidity
1 mis-stack in 4000 pages
1 mis-fold in 2000 pages
NOTE: A mis-stack is defined as any media movement in the stacker which results
in a fatal printer fault (printer halts), causes the media to overflow the
stacker, or requires operator intervention. A mis-fold is defined as
abnormal media handling in the stacker which allows printing and stacking
to continue and does not result in paper jams, fatal printer faults, or stacker
overflow.
Extensive testing has proven that the stacker performs reliably when stacking
20 lb. paper with a 1/32” tie, eight cuts per inch and 20 lb. microperf paper.
Products which may result in stacker mis-stacks or mis-folds are:
S
16 lb. (or lighter) paper
S
Microperf paper of less than 20 lb. weight
S
Light paper at high humidity
S
Paper with perforations having more than 8 cuts per inch
S
Label stock with a weak backing and several labels per sheet.
Auto Stacker Interface Specifications
S
3–24VDC is required to operate the solid-state relay.
S
At 5VDC, the relay draws <4mA
S
The potential across these wires should exist when paper begins to move (as evidenced
by the PMOVE signal on the engine/controller interface) and continues for about 0.5
seconds after the PMOVE signal is absent.
S
The connector on the Stacker is a Molex Mini-Fit Jr. Receptacle, (Molex P/N 39–01–2020).
S
The matching plug on the OEM’s connecting wire is the Molex Mini Fit Jr. Plug (Molex P/N
39–01–2021).
S
Maximum cable length from the printer to the stacker is undefined at this time.
S
No shield ground is provided at the stacker end. This prevents undesirable ground loops.
