3.8 Can I print a permit or other graphic on windowed envelopes? (Both)
The specification rules out window envelopes for two reasons. The first reason is that the printer is an
addressing printer and addresses are not printed on window envelopes. The second is that feeding of
window envelopes can result is significant skew and or jam issues with the material. Any customer that
wants to print just a permit or other graphic on a windowed envelope (stuffed or empty) is welcome to do
so. However we reserve the right to inform the customer that Pitney Bowes is not responsible for the
overall performance of the printer on such a job.
4. Fixed Head
4.1 General
4.1.1 Can Nozzle Keep Alive and Periodic Purge be run at the same time? (Fixed)
Yes, but it is strongly recommended that the user only use one or the other at a given time or on a given
job. The recommended mode of operation is Purge on First Piece coupled with Nozzle Keep Alive. Only if
the quality of the piece is of the utmost importance should Periodic Purge be used to keep the nozzle clear
and functioning properly.
Since a purge pattern can take up to 3” of material to print, it is strongly recommended that for any
materials shorter than 5” (127 mm) that only Nozzle Keep Alive is used and neither Purge on First Piece
nor Periodic Purge be employed.
4.1.2 Why am I getting “Paper Too Long” error? (Both)
Paper Too Long error is cause by the fact that the envelope trail edge did not show up as expected. In most
cases, it is a result of feeder stream feeding material. To eliminate the problem, first reset the H Block
separator gap.
Next, make sure the thickness adjustment is appropriate. On the WF96, you also need to make sure the
transport takeaway rollers have sufficient force applied, moving the crank to lower notches to increase the
force if necessary.
If the problem persists, check the separator tip on the H Block for severe worn flats.
For WF81 replace the tip if necessary. For WF96, rotate the separator tip to an unworn position if available.
If not, replace the separator tip.
4.1.3 Is it normal for the feeder to start and stop during the printing process? (Both)
Yes, it is. When the printer is waiting for data to be transmitted from the PC and it is not to print, the feeder
will stop. This occurs more often in printing through TCP/IP or when the envelope layout is very
complicated. It also could be due to the PC configuration.
It is likely that the settings in the PC are restricting the network throughput. This can be improved by
turning Advanced Printing Features off in the driver when submitting the job.
If you are using TCP/IP, try swapping to USB (if possible) and see if the problem is resolved. If it is, then
the network capability or settings are the problem.
If the problem still persists, try and reduce complexity of the print piece by either removing elements from
the layout or placing fixed portions into an overlay to load into the machine before the job starts.
It is better to adjust the Transport Speed down or the Feed Gap to manual and increase it until the feeder
does not stop regularly during the job. This is better for the printer and provides better throughput through
the machine as well as better quality operation.
The printer is also prone to encountering other errors when it is cycling the feeder on and off during a job.
This is another reason to change the job settings to eliminate the potential issue.
