SELECTING A QUALITY FORM
Although the FormsPro 4000 series printers have been designed to handle difficult forms, you
may come across a form that does not feed reliably or provide adequate print quality on all
copies.
One of the main causes of paper misfeeds is a form that is “tented”. Tenting is a tent-like
bulge at the perforation when forms are unfolded from the box. The printer allows a
maximum form thickness of .025 inches, which a badly tented form may exceed.
Tenting is usually caused by glue drying on the perforation after the forms maker puts the
forms into the box, or forms which are not glued at all. Forms with solid glue lines which run
vertically down the entire form are the most susceptible. If you experience such a problem,
request “interrupted glue line” forms from your vendor. This method stops the glue
approximately three-quarters of the way down the form and then resumes gluing at the top of
the next form. The gluing should not begin too far below the top of the form or pages of the
form will be able to fan apart and be a potential cause of jamming.
Another area where not all forms are alike is in the quality of carbon paper used, or in the
way carbonless inks are applied. If the back copies of your form are too light, request a
quick-release carbon or a higher quality carbonless inking method.
REPLACING THE AC POWER FUSE
Use the following procedure to replace the fuse if it should ever become necessary:
1. Unplug the line cord from the back of the printer.
2. Use a phillips screwdriver to remove the two black screws that are located just above
the line cord socket.
3. Open the case like you would normally do when you load paper.
4. As viewed from the front of the printer, locate the AC cover in the right rear corner of
the chassis. Then remove the screw that secures the cover to the bottom of the chassis.
5. Carefully remove the AC cover to expose the AC wiring.
6. Carefully remove the fuse from the filter circuit board. Be careful not to damage the
fuse mounting clips.
7. For continued protection from the risk of fire or damage to the printer, replace the fuse
only with the same type fuse. Refer to the label on the AC cover for information about
the fuse.
8. Reposition the AC cover over the AC wiring. Be careful not to pinch any wires
between the cover and the chassis. Then reinstall the three screws.
9. Reconnect the line cord to its socket on the rear of the printer.
