compressed air are available from many computer supply houses. The separator gap may not be
set properly.
Adjust the separators to the thickness of the mail piece.
A. Loosen the lock knobs to unlock all three H-Blocks.
B. Lift the H-Blocks to their highest position and lock in place.
C. Place a sample piece of material between the separator fingers (the lower section of the H-
Blocks) and the feed roller.
D. Lower only the H-Blocks that come in direct contact with the material and let them touch the
material.
E. Lock each separator in place. When lowering the H-Blocks, check that the material is between
the separator tabs and the feed roller.
Static buildup on materials can cause pieces to stick together and be pulled through the printer in a
batch. Be sure that material has been acclimated to the printer’s environment and you fan the
material prior to loading.
On the fixed head printers (WF81 and WF96) if normal adjustments do not stop a stream feeding
situation, try increasing the inter-piece gap to see if this reduces or eliminates the problem.
Worn separator tips could cause this problem also. See section 3.1.4 for more information.
Stack weight exceeded the product specification. Reduce the stack weight to be within spec to
improve the feeding performance.
The material had been processed too many times. For example, if for whatever reason, the
envelopes had been processed by inserters, printers, and other paper handling equipment multiple
times, there might be feeding issues due to drastically changed envelope physical characteristics.
3.3 What media size does Microsoft Add Printer Wizard Print Test Page require? (Both)
Microsoft Add Printer Wizard requires Letter size media; or A4 outside the US.
3.4 What media size does the driver’s Print Test Page (via Properties page) require? (Both)
Print Test Page requires Envelope #10 media; or Envelope DL outside the US.
3.5 What are the approved media types for the printer? (Both)
The printer can be used with envelopes, postcards, booklets-tabbed, self mailers, catalog envelopes and
paper. For more information, see Material Specifications in Section 2.5 of the Shuttle Head Service Manual
(SV61831) or Fixed Head Service Manual (SV61962); or the Appendix A in the in the appropriate Operator
Guide (see section 1.1.1).
3.6 The last few pieces in a stack do not feed reliably, what should I do? (Both)
The feeders work best with a stack of several inches of material in place. Either load additional material on
the stack, or tap or place light pressure on the top of the stack to get the last pieces to feed.
3.7 How much material can I put into the feeder and have it work correctly? (Both)
The feeders have been designed to work with a box of 500 #10 envelopes with is about 2500 grams of
weight. Any stack which weighs more than this will not feed properly. If the feeder takes a long time
pulling material from the stack and is continually showing fail to feed or out of material, try reducing the
amount of material in the feeder stack.
